The '''Audi A4''' is a line of luxury [[compact executive car]]s produced from 1994 to 2025 by the German car manufacturer [[Audi]], a subsidiary of the [[Volkswagen Group]]. The A4 has been built in five generations and is based on the [[Volkswagen Group B platform]]. The first generation A4 succeeded the [[Audi 80]]. The automaker's internal numbering treats the A4 as a continuation of the Audi 80 lineage, with the initial A4 designated as the B5-series, followed by the B6, B7, B8, and the B9.

The B8 and B9 versions of the A4 are built on the [[Volkswagen Group MLB platform]] shared with several models and brands across the Volkswagen Group. The Audi A4 [[automobile layout]] consists of a [[Front-engine, front-wheel-drive layout|front-engine design]], with [[transaxle]]-type [[transmission (mechanics)|transmissions]] mounted at the rear of the engine. The cars are [[front-wheel drive]], or on some models, "[[quattro (four wheel drive system)|quattro]]" [[all-wheel drive]]. The A4 is available as a [[Sedan (automobile)|sedan]] and [[station wagon]]. Historically, the second (B6) and third generations (B7) of the A4 also included a [[convertible]] version. For the B8 and B9 versions, the [[convertible]], along with a new [[coupé]] and 5-door [[liftback]] variant, was spun-off by Audi into a new nameplate called the [[Audi A5]].

It has been manufactured in [[Ingolstadt]] since its beginning, in [[Changchun]] [[China]] by [[FAW-VW]] since 2003 and in [[Aurangabad]] [[India]] by [[Audi India]] since 2007.<ref>{{Cite web|url=https://www.automobilesreview.com/auto-news/audi-starts-production-audi-a4-india/5106/|title=Audi starts production of new Audi A4 in India|website=AutomobilesReview.com|date=2 October 2008 }}</ref>
 
The B9 generation A4 and A5 will be replaced by B10 version of A5, as part of Audi's new naming convention.<ref>{{Cite web|url=https://www.autoexpress.co.uk/audi/a5/363773/new-2024-audi-a5-audi-a4-all-name|title=New 2024 Audi A5 is an Audi A4 in all but name|website=Auto Express}}</ref>

The first generation Audi A4 (known internally as the '''''Typ'' 8D''') debuted in October 1994,<ref>{{cite book| last=Buckley| first= Martin| title=BMW Cars| year=2002| publisher=Motorbooks| isbn= 978-0-7603-0921-6| page=158| chapter=The 1990s: New Models, New Markets, New Directions}}</ref><ref>{{cite web|title=Audi A4 |website=AutoGush |url=http://www.autogush.com/6671-audi-a4.html#.Ucx_o_nVCK9 |access-date=2013-06-27 |url-status=usurped |archive-url=https://web.archive.org/web/20130601162129/http://www.autogush.com/6671-audi-a4.html |archive-date=1 June 2013 |df=dmy }}</ref> with production starting November 1994 and European sales commencing in January 1995 for the 1995 model year.

It had a [[Front-engine, front-wheel-drive layout|front-mounted]] [[longitudinal engine]] and [[front-wheel drive]]. Many variations of the A4 were also available with Audi's [[quattro (four wheel drive system)|quattro]] [[four-wheel drive]] system. The A4 was initially introduced as a four-door [[sedan (automobile)|saloon/sedan]]; the Avant ([[station wagon|estate/wagon]]) was introduced in November 1995 and went on sale in February 1996.

Development began in 1988, with the first design sketches being created later that year. By 1991, an exterior design by Imre Hasanic was chosen and frozen for November 1994 production by 1992. The interior design was later finalized in 1992, with pilot production commencing in the first half of 1994. Development concluded in the third quarter of 1994, preceding November 1994 start of production.<ref>{{cite web |title=Picture |format=JPG |url=https://www.audiworld.com/news/99/sketches/sketch7.jpg |access-date=3 June 2018}}</ref><ref>{{cite web |url=https://www.audiworld.com/news/99/sketches/sketch5.jpg |title=Design sketch of exterior |format=JPG |access-date=3 June 2018}}{{dead link|date=April 2025}}</ref><ref>{{cite web |title=Design sketch of dashboard |format=JPG |url=https://www.audiworld.com/news/99/sketches/sketch13.jpg |access-date=3 June 2018}}{{dead link|date=April 2025}}</ref><ref>{{cite web |title=Design sketch of door panel |format=JPG |url=https://www.audiworld.com/news/99/sketches/sketch14.jpg |access-date=3 June 2018}}{{dead link|date=April 2025}}</ref>

A wide range of engines were available in European markets, between 1.6 and 2.8&nbsp;litres for [[petrol engine]]s; and a 1.9-litre [[diesel engine]] available with [[Volkswagen Group]]'s VE technology, capable of achieving a {{cvt|90|PS|kW bhp|0}} or {{cvt|110|PS|kW bhp|0}}. The 2.6 and 2.8-litre [[V6 engine]]s which had been carried over from the old [[Audi 80|80/90]] proved popular, although in North America, the 2.8-litre engine was the only V6 that was available there until 1997. A 2.4-liter version was developed especially for the Thai market, where import duty jumped from 60 to 100 percent on cars of over 2,400&nbsp;cc displacement.<ref name="Fujita">{{Cite web |last=Florer |first=John |title=Audi A4 |url=https://audispeed.com/audi-models/audi-a-series/audi-a4/ |access-date=2024-02-09 |website=Audispeed|date=30 January 2024 }}</ref>

The Audi A4 was the first model in the Volkswagen Group to feature the new 1.8-litre 20v engine with [[multi-valve|five valves per cylinder]], based on the unit [[Audi Sport]] had developed. A [[turbocharger|turbocharged]] 1.8T version produced {{cvt|150|PS|kW bhp|0}} and {{cvt|210|Nm|lbft|0|lk=on}} torque. Moreover, a [[quattro GmbH]] special edition of the B5 1.8T was later available in Germany and Europe, for which the engine's power output was raised to {{cvt|180|PS|kW bhp|0}} and {{cvt|235|Nm|lbft|0}}. Five-valve technology was also added to a reengineered V6 family of engines in 1997, starting with the 2.8-litre V6 30v, which now produced {{cvt|193|PS|kW bhp|0}}, followed by a 2.4-litre V6 which was a downsize from the previous 2.6 litre, {{cvt|150|hp|0}} engine, but with a power increase to {{cvt|165|PS|kW bhp|0}}.

Audi also debuted their new [[tiptronic]] automatic transmission on the B5 platform, based on the unit [[Porsche]] developed for their [[Porsche 964|964]]-generation [[Porsche 911|911]]. The transmission is a conventional [[automatic transmission|automatic]] gearbox with a torque converter offering the driver a fully-automatic operation or manual selection of the gear ratios.

The B5 marked Audi's continued move into the midsize luxury car segment, having started this trajectory notably with later model years of the preceding [[Audi 80#B4 .281991.E2.80.931996.29|Audi 80/90 B4]]. Despite initial mechanical problems, overall build and assembly quality were lauded both by the automotive press and within Audi and Volkswagen, and at the time, parent company Volkswagen declared the B5 the company-wide build quality benchmark for all its other models.

===Facelift (1999–2001)===

The Audi A4 B5 saw nearly constant minor changes and alterations throughout its seven-year run. Moreover, a significant [[facelift (automobile)|facelift]] was introduced for the 1998 B5 model year at the 1997 [[Frankfurt Motor Show]], with sales beginning in Europe in early 1998. The 2.8-litre 30-valve [[V6 engine]] replaced the 2.8-litre 12-valve. A 2.5-litre V6 [[Turbocharged Direct Injection]] [[diesel engine]] with {{cvt|150|PS|kW bhp|0}} was standard on the Quattro. A six-speed manual gearbox was available, as well as the new high-performance [[Audi S4]], now part of the A4 lineup (the previous S4 had been an [[Audi 100]]). Cosmetic updates included new rear lights, headlights, door handles, and another minor exterior/interior changes.

In mid-1998, the 1.8 20vT engine available outside Europe had its power output raised to {{cvt|170|PS|kW bhp|0}}. The previous [[Kühnle, Kopp & Kausch|KKK]] K03 [[turbocharger]], although fundamentally unchanged, received revisions on the turbine side to prevent cracking due to heat.{{Citation needed|date=April 2009}} The 12-valve V6 was replaced by the 30-valve unit which had been available in Europe for two years.

A further facelift took place across the A4 and S4 platform in February 1999 as a 1999.5 model; changes were largely cosmetic but affected many components, such as both front and rear bumpers, the front and rear lights, the center console, and door handles.<ref>[http://www.audi-sport.net/vb/a4-s4-forum-b5-chassis/21095-a4-s4-faq-look-here-first-before-posting-questions.html?s=effa15359f9df4e926e0cde2e5cab52d#post548541 Audi Sport FAQ],{{dead link|date=April 2025}} retrieved 2012-04-01</ref> While outer body shell changes from the pre-facelift model were superficially subtle, it meant that no two body panels were directly interchangeable between each other. This facelift was known at Audi as a ''Grosse Produktaufwertung'' (''Major Product Upgrade''), as was also signified by facelift cars now carrying the denomination "8D'''2'''".

In 1999 Audi also debuted an even higher performance '''''R'''enn'''S'''port'' model (rennsport literally translates as ''racing sport''), the [[Audi RS4|RS4 Avant]], like its predecessor [[Audi RS2 Avant|RS2]], available only in the Avant bodystyle.

===Safety===
In the [[Euro NCAP]] safety and crash tests, the Audi B5 A4 received 3&nbsp;stars for front- and side-impact protection, but the last star is flagged to indicate that the driver may be subjected to a high risk of chest injury in the side impact.<ref name="euroncap.com">{{cite web |url=http://www.euroncap.com/tests/audi_a4_1997/14.aspx |title=Audi A4 |access-date=1 June 2008 |work=EuroNCAP.com}}</ref>

The next A4, internally designated '''''Typ'' 8E''', debuted on 10 October 2000, now riding on the [[Volkswagen Group B platform#B6|Volkswagen Group B6 (PL46) platform]]. The car's new styling was developed under Peter Schreyer between 1996 and 1998, inspired by the Bauhaus design language of the C5 (second-generation) [[Audi A6]] introduced in 1997. The 1.6-litre base model powerplant remained unchanged, but most other [[petrol engine|petrol/gasoline engines]] received either displacement increases, or power upgrades. The 1.8-litre 20-valve [[turbocharger|Turbo]] was now available in two additional versions, with {{cvt|150|PS|kW bhp|0}} or {{cvt|180|PS|kW bhp|0}}, this one with a standard six-speed [[manual gearbox]], while the naturally aspirated 1.6-litre [[straight-four engine]] and 2.8-litre [[V6 engine|V6]] were replaced by 2.0-litre, and all-[[aluminium alloy]] 3.0-litre units, still with five valves per cylinder, the most powerful of which was capable of {{cvt|220|PS|kW bhp|0}} and {{cvt|300|Nm|lbft|0}} of torque. The 1.9 [[Turbocharged Direct Injection]] (TDI) engine was upgraded to {{cvt|130|PS|kW bhp|0}}, with [[Unit Injector|Pumpe Düse (Unit Injector)]] (PD) technology, and was now available with [[quattro (four wheel drive system)|quattro]] permanent [[four-wheel drive]], while the 2.5 [[V6 engine|V6]] TDI high-end model was introduced with {{cvt|180|PS|kW bhp|0}} and standard quattro. This generation of quattro consisted of default of 50:50 front to rear dynamic torque distribution. A [[Robert Bosch GmbH|Bosch]] ESP&nbsp;5.7 [[electronic stability control|Electronic Stability Programme]] (ESP) system, with [[anti-lock braking system]] (ABS), [[brake assist]], and [[electronic brakeforce distribution]] (EBD) were standard across the range.

The Avant was introduced in June 2001 and arrived in European showrooms in September 2001.{{citation needed|date=February 2014}}

For 2002, Audi increased power in the 1.8 Turbo engines to {{cvt|183|PS|kW bhp|0}} and {{cvt|190|PS|kW bhp|0}} – the 190&nbsp;PS variant designated by a red 'T' on the boot lid. Available with four wheel drive and in the 2.5 TDI intermediate version to {{cvt|163|PS|kW bhp|0}}. A 2.0 engine with [[gasoline direct injection|Fuel Stratified Injection]] (FSI) was also available. A year later, Audi reintroduced the S4, now powered by a {{cvt|344|PS|kW bhp|0}} 4.2&nbsp;L [[V8 engine]], as well as an A4 Cabriolet [[convertible (car)|convertible]] variant ('''''Typ'' 8H'''), finally replacing the [[Audi 80|80]]-based Audi Cabriolet which had been discontinued in 2000. It included an electro-hydraulic operated roof, which lowered in under 30 seconds and incorporated some styling changes, such as body-coloured lower bumper and sill panels, which later found their way to the saloon version. The Audi A4 Cabriolet version was co-developed and manufactured by [[Karmann]].<ref>{{Cite web|url=https://www.audiworld.com/articles/production-of-the-new-audi-a4-cabriolet/|title=Production of the New Audi A4 Cabriolet|date=26 March 2002}}</ref>

Audi introduced a [[continuously variable transmission]] developed by [[LuK]], named [[multitronic]], which replaced the dated conventional automatic transmission on [[front-wheel drive]] models. There have been widespread complaints from consumers around the world that the transmission box is prone to electronic glitches as well as mechanical problems.<ref>{{cite web |url= http://www.audi-gearbox-problems.co.uk |archive-url= https://web.archive.org/web/20101220011534/http://www.audi-gearbox-problems.co.uk/ |archive-date= 20 December 2010 |title= Audi Gearbox Problems |access-date= 2012-04-15 }}</ref><ref>{{cite web|url=http://www.audi-forums.com/b6-forum/47603-cvt-reality-check.html|title=CVT reality check|access-date=2012-04-15}}</ref>

Borrowing from the [[Audi A6]], the boot was redesigned to remove the extension of the top edge with a smoother fold line. The rear light assemblies now formed part of the top line, these styling cues were eventually borrowed by other European as well as Asian manufacturers.<ref>{{cite web |url=http://www.boldride.com/ride/2000/audi-a4#gallery/4 |title=Audi A4 specification |date=2011 |access-date=29 April 2015 |archive-url=https://web.archive.org/web/20160409145742/http://www.boldride.com/ride/2000/audi-a4#gallery/4 |archive-date=9 April 2016 }}</ref>

A sport package named 'Ultra Sport' was introduced in the North American market shortly before the B6 was replaced by the B7. It included aluminium interior trim and door sills, [[Audi S and RS models#S line|"S line"]] steering wheel, front and rear spoilers, side skirts, and [[quattro GmbH]] designed 18-inch RS4 alloy wheels.

Audi introduced a heavily facelifted A4 in late 2004, with the internal designation of '''[[Volkswagen Group B platform#B7|B7]]'''. Although given a new platform designation, the B7 was essentially a heavily facelifted and revised version of the B6, with revised steering settings, suspension geometry,{{specify|date=February 2014}} new [[internal combustion engine]] ranges, navigation systems and chassis electronics (including a new advanced [[Robert Bosch GmbH|Bosch]] ESP&nbsp;8.0 [[electronic stability control|Electronic Stability Programme]] (ESP) system). The front grille assembly changed to a tall trapezoidal shape in the same manner as the C6 (third-generation) [[Audi A6]]; however, the dashboard and interior were virtually unchanged from the B6 aside from minor detailing.

Audi's internal platform nomenclature uses PL46 ('''p'''assenger car '''l'''ongitudinal platform, size '''4''', generation '''6''') for both B6 and B7 chassis. The '''''Typ'' 8E''' and '''''Typ'' 8H''' internal designations are also carried over from the B6 A4 range, but now have an additional identifying suffix – 8EC for the saloon, 8ED for the Avant, and 8HE for the Cabriolet.

The engine lineup received many additions. The 2005 introduction of [[gasoline direct injection|Fuel Stratified Injection]] (FSI) on the 2.0 TFSI and 3.2 [[V6 engine|V6]] FSI [[petrol engine|petrol/gasoline engines]], as well as other refinements, increased power output to {{cvt|200|PS|kW bhp|0}} and {{cvt|255|PS|kW bhp|0}}, respectively. These engines both use a four-valve per cylinder configuration. The prior 5-valve design was incompatible with the FSI direct injection system (due to the siting of the fuel injector, now discharging directly into the combustion chamber). The 2.0 [[Turbocharged Direct Injection]] (TDI) [[diesel engine]] now combined [[Unit Injector|Pumpe Düse (Unit Injector)]] (PD) technology with 16 valves, while the larger 2.5 TDI V6 diesel was superseded by a 3.0 V6 TDI, offering a {{cvt|204|PS|kW bhp|0}} model during the year 2005 which was upgraded to a {{cvt|233|PS|kW bhp|0}} model in 2006. A 2.7 V6 TDI was added later.

[[Torsen]] T-2 based [[quattro (four wheel drive system)|quattro]] permanent [[four-wheel drive]] remained as an option on most A4 models. Audi retained the 5 speed manual transmission with the 1.9 TDI and 2.0 non turbo petrol engines while introducing the 6 speed manual for all higher output variants. As before, [[multitronic]] [[continuously variable transmission]] (CVT), now with selectable 'seven-speeds', was an option on front-wheel drive models, whilst a conventional [[ZF Friedrichshafen|ZF]] [[list of ZF transmissions#6-speed auto|6HP 6-speed]] [[tiptronic]] [[automatic transmission]] was an option on the quattro [[four-wheel drive]] models.

In addition to the [[Audi S4]], which carried over the [[powertrain]] from the B6 S4 – Audi reintroduced the [[quattro GmbH]] developed [[Audi RS4]] ('''RS''' for '''''R'''enn'''S'''port'') to the lineup, for the first time on the [[sedan (automobile)|saloon/sedan]] and [[Convertible (car)|Cabriolet]] body, and with a naturally aspirated, but high-revving 4.2-litre [[V8 engine|V8]] FSI engine. Another inclusion on the RS4 was the latest generation [[Torsen]] T-3 Quattro 4WD system, which uses a 'default' asymmetric 40:60 front-rear dynamic torque distribution bias. This new asymmetric center differential was initially only available on the RS4 but was added a year later on the S4. The remainder of the B7 A4 range still used the T-2 50:50 default dynamic split center diff.

[[File:Audi A4 DTM Edition front.JPG|thumb|left|Audi A4 DTM Edition]]

A variant, developed by [[quattro GmbH]], was first introduced in May 2005, named "Audi A4 DTM [[special edition|Edition]]". It was inspired by Audi's race cars of the 2004 [[Deutsche Tourenwagen Masters]] and was reintroduced in 2006 as a regular option. The 2.0T FSI engine received revised software mapping to the ECU, which increased the output to {{cvt|220|PS|kW bhp|0}} and {{cvt|300|Nm|lbft|0}} of torque. It was available with front-wheel drive, or Quattro four-wheel drive.

The B7 Cabriolet model arrived later than the other two body variants, being first shown in late 2005 and with sales beginning in February 2006. New on the Cabriolet was an entry-level 2.0 TDI version, which was not offered with the Multitronic CVT gearbox. The Cabriolet version was produced by [[Karmann]] until February 2009.<ref>{{cite web | url = http://www.nord-west-media.de/index.php?id=3198 | archive-url = https://web.archive.org/web/20090304051931/http://www.nord-west-media.de/index.php?id=3198 | archive-date = 2009-03-04 | title = Letztes Audi A4-Cabriolet läuft heute vom Band | trans-title = Final Audi A4 Cabriolet to leave the production line today | language = de | publisher = Nord-West-Media TV & Nachrichten GmbH | work = Nord-West-Media TV | date = 2009-02-20 }}</ref>

In 2007 Audi introduced a version of the B7 named the 'Special Edition', which built on the S-Line specification and also included the black optics pack, the RS4 style 8J X 18 '7-arm double-spoke' design alloy wheels, Two-tone Graphite/Black Volterra leather, 3-spoke sports leather/Alcantara multi-function steering wheel with gear knob and hand brake handle in Alcantara with silver stitching, ventilated cross-drilled front disc-brakes, black tailpipes and black roof rails (Avant model only). It also had a power increase of 20 PS, giving an output of 220 PS on the 2.0T model.

According to 2007 Swedish vehicle inspection data, the Audi A4 Avant with [[diesel engine]] is the most reliable vehicle available on the market, with vehicle inspection rejection rate of 0.0% in three-year-old category.<ref>{{Cite web|url=http://www.tuulilasi.fi/valokeila/?subarea=uutiset&article=149985&page=2 |archive-url=https://web.archive.org/web/20081218221850/http://www.tuulilasi.fi/valokeila/?subarea=uutiset&article=149985&page=2 |archive-date=18 December 2008 |title=Mallisarjat vikojen yleisyysjärjestyksessä |trans-title=Model series in order of frequency of defects |language=fi}}</ref>{{Failed verification|date=March 2012}}

When the successor B8 A4 range was introduced, the B7 series A4 was restyled and [[rebadged]] as the [[SEAT Exeo]] in 2008 with changes to the front and rear plus interior trim from the A4 Cabriolet. The entire Audi B7 A4 production line from Audi's [[Ingolstadt]] [[list of Volkswagen Group factories|plant]] was dismantled and sent to [[Volkswagen Group]]'s [[SEAT]] factory in [[Martorell]], Spain.<ref name="exeo">{{cite web|url=http://www.carmagazine.co.uk/Drives/Search-Results/First-drives/SEAT-Exeo-first-drive/|title=Seat Exeo (2009) CAR review|last=Kirk|first=Julian|date=4 November 2008|work=Car Magazine|access-date=13 January 2009}}</ref>

[[File:2012 Audi A4 B8 interior.jpg|thumbnail|left|Interior (facelift)]]
Audi released the first official pictures of the [[Volkswagen Group B platform#B8|B8]] series A4 in August 2007 and unveiled the car to the public at the September 2007 [[Frankfurt Motor Show]]. [[sedan (automobile)|Saloon/sedan]] and Avant ([[station wagon|estate/wagon]]) models are offered. The Avant was unveiled to the public at the March 2008 [[Geneva Motor Show]]. For North America's destined models, the B8 continued in production for the 2016 model year, while Europe began deliveries on the 2016 B9 model.

The B8 A4 is built on a variant of the [[Volkswagen Group MLB platform|Audi Modular Longitudinal Platform]], a platform that is also used in the [[Audi A5]] [[coupé]]. While prior A4 chassis were limited in [[wheelbase]] due to the relationship between the engine, transmission and front axle, the MLP allows for a reduced front overhang, resulting in a greater wheelbase length without the same increase in overall length.<ref>{{Citation | last =Monticello | first =Mike | title =2009 Audi A4 3.2 Quattro | journal =[[Road & Track]] | volume =60 | issue =2 | page =104 | date =October 2008 }}</ref> This effectively redistributes the centre of gravity slightly rearwards, improving handling by better balancing vehicle mass between the front and rear axles. The estimated static front:rear weight ratio of the B8 A4 is approximately 55:45, depending on body style and engine. The relocation of the steering rack in front of the axle also improves handling over previous A4 platforms.{{Citation needed|date=March 2009}} Key to the implementation of MLP is the novel mounting of the [[Differential (mechanical device)|differential]] in front of the clutch. This is achieved by driving the flywheel/clutch remotely by means of a 'top hat' shaped drive plate, between which the differential lay shaft passes, whilst power transmission to the final drive is via an inclined transfer shaft which runs the length of the transmission unit. Whilst the platform retains Audi's "overhung" engine mounting position, the front axle is now 152mm further forward than the previous B6/B7 generation platform.<ref>{{cite book|title=Audi A5 – Self Study Programme|date=January 2007|publisher=Audi AG|page=30|url=http://training.avme.net/admin/Upload/SSP/4801_392%20Audi%20A5%20generell.pdf|access-date=5 January 2015|archive-url=https://web.archive.org/web/20150105113255/http://training.avme.net/admin/Upload/SSP/4801_392%20Audi%20A5%20generell.pdf|archive-date=5 January 2015|df=dmy-all}}</ref> The transfer shaft, however, has the effect of creating a large "bulge" on one side of the transmission tunnel, which on right-hand drive versions forces the pedals to be badly offset, which has attracted criticism from the British motoring press in particular.

The B8 A4 has increased in wheelbase by {{convert|160|mm|in|1}} and in length by {{convert|117|mm|in|1}} over the prior B7, which has allowed for increased rear seating legroom. Although the overall dimensions have increased, the curb weight has dropped some 10%. The boot (trunk) has also increased to {{convert|480|L|cuft|1}} for the saloon (sedan) version. The A4 Avant will have a maximum capacity of {{cvt|1430|L|cuft|1}} with the rear seats folded down.

Reception has been mixed, with praise for the Audi A4's increased size, giving it best-in-class rear legroom and trunk space in the compact executive car segment.<ref>{{cite news|url=http://www.iol.co.za/motoring/latest-launches/audi-a4-replacement-hot-and-cool-1.852835|title=Audi A4 replacement: Hot and cool|last=Rutherford|first=Mike|date=6 November 2007|work=iol.co.za|access-date=11 May 2011}}</ref> Its inline-4 2.0 TFSI engine, while efficient providing plenty of torque, was considered lacking and less refined compared to 6-cylinder engines of lighter rivals who posted faster acceleration times. However, the [[Audi S4]] [[sports sedan]] has been well-received for its V6 3.0 TFSI engine's power and efficiency.<ref>{{cite news| url=https://www.nytimes.com/2009/12/27/automobiles/27ulrich-best.html?pagewanted=2&_r=1&sq=Ford%20Taurus%20disappointing&st=cse&scp=1 | work=The New York Times | title=A Holiday From Wishful Thinking | first=Lawrence | last=Ulrich | date=27 December 2009 | access-date=2 May 2010}}</ref><ref>{{cite news| url=https://www.nytimes.com/2009/02/08/automobiles/autoreviews/08audi-a4.html?_r=1&pagewanted=2 | work=The New York Times | first=Lawrence | last=Ulrich | title=A Class Act Matures in Size and Price | date=8 February 2009}}</ref><ref>{{cite web |url=http://www.newcartestdrive.com/review-intro.cfm?Vehicle=2009_Audi_A4&ReviewID=4525 |title=2009 Audi A4 Review, Prices, Photos |publisher=New Car Test Drive |access-date=11 October 2010 |archive-date=14 January 2010 |archive-url=https://web.archive.org/web/20100114094230/http://newcartestdrive.com/review-intro.cfm?Vehicle=2009_Audi_A4&ReviewID=4525 }}</ref>

The B8 A4 was facelifted in early 2012. During a model, cycle changes are made to integrate new technologies and to keep the model competitive. These changes are referenced based on the model year (MY) of the car. In Australia, the B8 has undergone 2 revisions leading to three variants, the B8, B8 MY10<ref>{{cite web|url=http://www.ozaudi.com/forums/showthread.php/19978-MY10-changes-for-Australian-Audi-range |title=MY10 changes for Australian Audi range |publisher=Ozaudi.com |access-date=2011-05-16}}</ref> and B8 MY11.

The [[quattro (four-wheel-drive system)|quattro]] permanent [[four-wheel drive]] system uses the latest [[Torsen]] T-3 centre [[differential (mechanical device)|differential]], with a default 40:60 front to rear asymmetric torque distribution ratio (used first on the [[Audi RS4#B7|B7 RS4]]) as standard. (Previous A4 Quattro models split torque with a default front:rear 50:50). The additional torque bias applied to the rear wheels helps mimic the driving dynamics of rear-wheel drive cars.

Audi was reported to stop offering 3.2L V6 models in 2010 model year,<ref>{{cite web|last=Lavrinc |first=Damon |url=http://www.autoblog.com/2009/04/22/audi-dropping-3-2-liter-v6-from-2010-a3-a4-and-tt/ |title=Audi dropping 3.2-liter V6 from 2010 A3, A4 and TT |publisher=Autoblog.com |date=22 April 2009 |access-date=2010-10-20}}</ref> but still offers them as of August 2011 (Germany).

All [[petrol engine]]s use [[gasoline direct injection|Fuel Stratified Injection]] (FSI), and all [[diesel engine]]s use the [[common rail]] fuel delivery (with a pressure of {{convert|1600|bar|psi}}), with [[piezoelectricity|piezo]] [[fuel injection|injectors]] of their [[Turbocharged Direct Injection]] engines.

With the 2012 facelift (the B8.5) came additional 163ps TDIe and TDI Ultra engines, the latter requiring the addition of [[adblue]] allowing for cleaner running, both of which fell into the lower emissions tax bracket for the UK, yet presenting a significant performance improvement over the base 136ps and mid-range 143ps models.<ref>{{Cite web|url=https://www.autocar.co.uk/car-review/audi/a4/first-drives/audi-a4-20-tdie|title = Audi A4 2.0 TDIe |first1=Vicky |last1=Parrot |date=2012-03-16}}</ref>

====Transmissions====
In 2009, Audi announced the seven-speed [[Direct-Shift Gearbox|S-Tronic]] [[dual clutch transmission|dual-clutch]] automatic transmission as an option for A4 in the UK and European markets.<ref>AutoBlog.com [http://www.autoblog.com/2009/02/06/audi-a4-and-a5-get-s-tronic-gearbox-abroad-u-s-still-waiting/ Audi A4 and A5 get S-Tronic gearbox abroad, U.S. still waiting]{{dead link|date=April 2025}}</ref>

All A4L models include Speed 8 [[multitronic]] [[Continuously variable transmission|continuously variable]]/[[manual transmission]], except for A4L 3.2 FSI quattro, which includes Tiptronic [[automatic transmission]].

Volkswagen settled a class-action lawsuit in 2013 involving the failures of the CVT transmission in its Audi A4 and A6 automobiles for model years 2002–2006.<ref>{{cite web|url=http://www.thenationaltriallawyers.org/2013/10/audi-cvt-suit-settlement-given-green-light/|title=Audi CVT Suit Settlement Given Green Light|work=The National Trial Lawyers}}</ref>

The facelift model of the Audi A4 was released in 2012 for the 2013 model year. It features redesigned LED headlamps and taillights, front air dam with fog lamps, and closely set twin exhausts. Interior changes include Bluetooth connectivity for audio streaming (nav equipped models only) and a redesigned ignition key. Controls for air-conditioning, infotainment, and power windows gain chrome clasps. Other detail interior changes include larger steering column stalk switches first seen in the D4-series [[Audi A8]] and a simplified layout for the HVAC control panel – for example the temperature setting for the heated seats is now directly set by a single button and is no longer controlled using the MMI dial. The A4 includes a radio with eight speakers as standard, while the MMI navigation system with voice dialogue is optional. A new "Drive Select System" allows drivers to choose comfort, dynamic, individual, or efficiency modes for fuel-efficiency. The power output of the 1.8 TFSI engine is 170 BHP and 320 Nm of torque – up 10 BHP and 70 Nm from the previous versions. Electromechanical power steering is standard.

In Europe, the wide range of Audi A4 saloon and Avant estate are available with the 1.8 TFSI, 2.0 TFSI, and 3.0 TFSI gasoline engines (same 7-speed S tronic and 3.0 TFSI supercharged V6 as the [[Audi S4]] but detuned to 272bhp and 292lb ft of torque in the A4 3.0 TFSI) [http://motoringme.com/reviews/twin-test-bmw-335i-vs-audi-a4-3-0-tfsi/ Twin Test: BMW 335i Vs Audi A4 3.0 TFSI…], as well as 2.0 TDI, 2.0 TDIe, and 3.0 TDI diesel motors. Trim levels are Attraction, Ambition, and Ambiente. In the UK, the A4 range is offered in SE, SE Technik, Technik, S line, and Black Edition model grades. All-wheel-drive Quattro is offered in most engine and grade combinations.

For North America, the facelift model Audi A4 sedan is only offered with a 2.0 TFSI turbocharged inline-4 gasoline engine, while the performance upgrade remains the [[Audi S4]] with a 3.0 TFSI supercharged V6 gasoline engine, and no diesel engines were offered.[https://www.motortrend.com/reviews/2013-audi-a4-s4-first-drive/] Model grades are Premium, Premium Plus, and Prestige. The Avant was discontinued, leaving the Allroad Quattro as the only station wagon body style. For the 2016 model year, the A4 and S4 continued in B8 production. The B9 A4 would not reach the North American market until the 2017 model year, while the S4 variant would not be available until the 2018 model year.

The fifth-generation of the A4 was revealed in June 2015 when pre-production versions were released to the motoring press, with the official launch occurring at the [[Frankfurt Motor Show#2015|Frankfurt Motor Show]] in September 2015.<ref name="autocar.co.uk">{{cite web|url=http://www.autocar.co.uk/car-news/new-cars/2015-audi-a4-revealed|title=2015 Audi A4 - latest pictures and details - Autocar|website=www.autocar.co.uk}}</ref> This generation of the A4 is the fifth to carry the A4 badge and is commonly referred to as the '''B9''', representing the ninth generation of the Audi 80/A4 series, which were originally (but no longer) based on the [[Volkswagen Group B platform|B platform]]. The B9 is slightly larger than the outgoing B8, but Audi claims the new A4 is around {{cvt|120|kg|lb|0}} lighter than its predecessor due to the use of its new lightweight aluminum-hybrid construction. The B9 also comes with a number of A4 firsts such as virtual cockpit, Apple CarPlay and Android Auto, full-color head-up display, and Audi pre-sense.

Common misconception is that the “B9” or 8W Generation started in 2017, because that’s when the USA market got it but it was available in European markets in the model year 2016. 

=== Trims ===
The Audi A4 launched with three petrol, and four diesel engines.<ref>{{Cite web |date=2015-06-28 |title=High tech all the way – the new Audi A4 and A4 Avant |url=https://www.quattroworld.com/blog/high-tech-all-the-way-the-new-audi-a4-and-a4-avant/ |access-date=2024-07-12 |website=QuattroWorld |language=en-US}}</ref> US models received only the gasoline versions which consisted of the base 2.0L turbo found in the ultra model, the standard 2.0L turbo in the standard grades, and the V6 engines offered in the S4 and RS4 (3.0L and 2.9L respectively). The Ultra introduced Audi's new high efficiency variant of the EA888 that achieves best in class fuel economy through the use of an increased compression ratio engine (9.6:1 to 11.7:1) with shorter compression and longer-expansion phases. It sends this power through a 7-Speed dual-clutch powering the front wheels only. This allows the A4 to achieve an EPA rating of 27 city/37 highway/31 combined.<ref>{{Cite web |title=Audi |url=https://media.audiusa.com/releases/114 |access-date=2024-07-12 |website=media.audiusa.com}}</ref> This variant was only offered until 2020 at which point it was rebranded to the 40 TFSI. Performance figures are shown under the engine variants below.

Available model grades are Premium, Premium Plus, Ultra Premium, Ultra Premium Plus and Prestige. Ultra models featured improved fuel efficiency and reduced emissions, and were only available in the FWD configuration. Every other model was available in either FWD or Quattro. The S Line and Black Optic packages were also made available. The S Line package uses skirts, bumpers, seats and wheels from the Audi S4, and adds an aluminum inlay to the interior consoles. The Black Optic package, or Black Edition, also uses the S4's body kit, but replaces the exterior's chrome trim with black counterparts.

A slight facelift was introduced in 2019, featuring new front and rear bumpers inspired by the [[Audi RS 4]]. Additionally, the Titanium model grade was introduced to replace the Ultra Premium and Ultra Premium Plus models.

=== Facelift (2020–2025) ===
The facelift model, also known as the '''B9.5''', was made available in 2020. It brought the A4's aesthetic in line with the S4, [[Audi A6|A6]], [[Audi A7|A7]] and [[Audi A8|A8]]. In addition to redesigned headlights and taillights, almost every body panel on the A4 was altered, with only the hood, trunk and roof remaining untouched. Notably, the character line that ran the length of the A4 was removed, with creases added to the front and rear fenders in its place. While the interior was largely untouched, the mechanical controls for the infotainment center were replaced with a touchscreen and larger display. Following the facelift, the A4 and S4 now share their body panels, with their grilles and badges being the only external distinctions between the models.

Post-facelift, the Titanium model was removed from production, leaving only the Premium, Premium Plus and Prestige model grades. Additionally, US delivered Post-facelift A4's are only available in the Quattro configuration. Whereas front wheel drive continued to be available for the rest of the world. Noting that the B9.5 introduced Quattro-Ultra technology, a system which can disconnect the all wheel drive to save fuel during specific driving conditions, thus negating the disadvantage of Quattro's additional fuel consumption. The Black Optic and S Line packages also return for select models. The Black Optic package can be equipped on any Premium Plus or Prestige Model, while the S Line model can be applied to any Premium Plus or Prestige Model with a 45 TFSI engine. The S Line package makes no changes to the exterior beyond its badging, as the A4 and S4 now share their body kits. It instead provides an aluminum inlay for the interior, improved seats, and stainless steel pedals.

In addition to the above packages, Audi also manufactures aftermarket accessories for the A4, including decals, spoilers, mirror caps and tail pipes.
