== Overview ==

Since the 156's introduction, various four cylinder engine configurations were available and included the ''[[Alfa Romeo Twin Spark engine]]'' (1.6&nbsp;L - {{cvt|120|PS|kW}}, 1.8&nbsp;L - {{cvt|144|PS|kW}} and 2.0&nbsp;L - {{cvt|155|PS|kW}}) 16 [[Four-stroke cycle engine valves|valve]] models with [[variable valve timing]], along with the [[straight-4]] 1.9-litre 8-valve {{cvt|105|PS|kW}}. The range also included a [[straight-5]] 2.4-litre 10-valve {{cvt|136|PS|kW}} ''[[JTD]]'' [[common rail]] [[turbodiesel]] engine. Until January 2002, the range-topping engine was the venerable 2.5-litre 24-valve [[Alfa Romeo V6 engine|''Busso'' V6]] - now with [[double overhead camshaft]]s and [[multi-valve|four-valve]] heads - rated at {{cvt|190|PS|0}}.

Initially the 156 range was available with different options (packs) like a sport pack that included Blitz clothing, [[MOMO (company)|Momo]] leather interior and [[Recaro]] seats, it also included {{convert|16|in|mm|adj=on}} wheels, lowered suspension and leather-trimmed [[steering wheel]] and [[Gear stick|gear knob]]. The Lusso pack added with Momo's [[mahogany]] steering wheel and gear knob and for Nordic countries, a special winter pack consisting of fog lights, headlight washers, and heated seats was available.<ref name="alfaromeopress.com" />

Starting from 1999 a five-speed ''[[Selespeed]]'' automated manual transmission was available as an option on the 2.0-litre Twin Spark version and a four-speed automatic ''Q-System'' on the 2.5-litre V6 version,<ref name="alfaromeo.com.au">{{cite web |url=http://www.alfaromeo.com.au/default.asp?action=article&ID=17556 |title=Alfa Romeo history 1990–2000 |website=alfaromeo.com.au |access-date=25 April 2007 |archive-url=https://web.archive.org/web/20070219155309/http://www.alfaromeo.com.au/default.asp?action=article&ID=17556 |archive-date=19 February 2007 |url-status=dead }}</ref> the Q-system provided the option of using the car as a normal automatic or being able to shift manually with [[H-pattern]],<ref name="autoweb.com.au" /> it has three automatic modes: city, sport and ice.

A significant addition to the 156 range came in 2000 with the introduction of the '''Sportwagon''' [[station wagon]] or estate bodystyle, debuting at the [[Geneva Motor Show]]. The new bodystyle was in development from 1998 by [[Stola (automotive company)|Stola]] under the project code '932 AF'. According to Stola's records the initial considered name was "Powerwagon".<ref>{{Cite web|url=https://www.studiotorino.com/index.php?option=com_content&view=article&id=510:19980202-156-sw-2&catid=50&lang=en&Itemid=840|title=STUDIOTORINO - 19980202_156_sw|website=studiotorino.com|access-date=14 September 2022}}</ref> While not a core part of the company's range, estate versions of the Alfasud and 33 - the first to carry the name Sportwagon - were produced and a 75 Sportwagon was shown at Geneva, but became an early victim of the Fiat takeover. The Sportwagon was also available with Boge-[[Nivomat]] self-levelling hydropneumatic rear suspension.<ref name="italiaspeed">{{cite web|url=http://www.italiaspeed.com/new_models/new_models_2003/156_restyling/156restyling_05.html |title=Alfa Romeo 156 restyling article, page. 5 |access-date=25 April 2007 |archive-url=https://web.archive.org/web/20120225135854/http://www.italiaspeed.com/new_models/new_models_2003/156_restyling/156restyling_05.html |archive-date=25 February 2012 |url-status=live }}</ref> The Sportwagon was marketed as a lifestyle estate without large carrying capacity.<ref name="carenthusiast.com">{{cite web |url=http://www.carenthusiast.com/roadtests.html?article=439 |title=2003 Alfa Romeo 156 2.0 JTS Sportwagon review |access-date=6 August 2007 |website=carenthusiast.com |archive-url=https://web.archive.org/web/20120207185904/http://www.carenthusiast.com/reviews.html?mode=article&id=439 |archive-date=7 February 2012 |url-status=dead}}</ref> The Sportwagon bodystyle filled a gap in the market that Alfa Romeo had distanced themselves from since the [[Alfa Romeo 33 Series|33]] [[SportWagon]] of the 1980s.

In 2001 engines were upgraded to comply with the [[Euro III]] standards and were rated at {{cvt|120|PS|kW}} (1.6&nbsp;L), {{cvt|140|PS|0}} (1.8&nbsp;L), {{cvt|150|PS|0}} (2.0&nbsp;L) and {{cvt|192|PS|kW}} (2.5&nbsp;L).

==Design==
Designed by Alfa Centro Stile under the guidance of head designer [[Walter de'Silva]] the 156s shape was intended to be distinctly Alfa Romeo.<ref name="uk.cars.yahoo.com">{{cite web |url=http://uk.cars.yahoo.com/car-reviews/car-and-driving/alfa-romeo-156-75.html |title= Alfa Romeo 156 Women's view |access-date=27 January 2008|website=uk.cars.yahoo.com |archive-url=https://web.archive.org/web/20110605235718/http://uk.cars.yahoo.com/car-reviews/car-and-driving/alfa-romeo-156-75.html |archive-date=5 June 2011}}</ref> Its styling included high, curved flanks, retro styled front door handles, recessed rear door handles, and a deep [[Grille (car)|grille]] requiring an off-centre licence plate holder. The design featured visually deemphasized rear door handles and accentuated front handles, giving the illusion of a coupé profile. The design was influenced by the Alfa Romeo 1900, Giulietta and Giulia.<ref name="alfa156.net">{{cite web|url=http://www.alfa156.net/fr_index.html?/history.html |title=History of Alfa Romeo 156 (project 932) (v2.0) |access-date=25 April 2007 |website=alfa156.net |archive-url=https://web.archive.org/web/20110723010156/http://www.alfa156.net/fr_index.html?%2Fhistory.html |archive-date=23 July 2011 |url-status=dead }}</ref> The 156 achieved a [[drag coefficient]] (''C''<sub>d</sub>) of 0.31.<ref name="alfaromeopress.com" />

The original interior uses a scalloped upper dashboard and a simple centre console. The main controls and displays are angled to the driver. The interior design lacks cup holders.

The 156 Sportwagon features fold-down rear seats to increase the luggage area normally covered by a privacy screen.

2002 saw an update to both the interior and exterior of the 156.

==Facelifts==

===2002 facelift (first series)===

2002 also saw the arrival of a [[Facelift (product)|facelifted]] interior with different matte-finish surfacing and chrome highlights.
This new version featured the [[Alfa Romeo 147|147's]] dual-zone digital [[Air conditioning|climate controller]] while the interior climate could also be controlled via an air quality sensor.<ref name="www.alfaromeopress.com">{{cite web|url=http://www.alfaromeopress.com/press/article/296 |title=New Alfa 156 and Alfa 156 GTA |access-date=5 February 2009 |website=alfaromeopress.com |archive-url=https://web.archive.org/web/20140512221153/http://www.alfaromeopress.com/press/article/296 |archive-date=12 May 2014 |url-status=live }}</ref> A different choice of colours were available for the interior, with the option of a two-tone interior very much like that on offer from its European rivals. A wider range of options including [[xenon]] lighting, tele-informatics (CONNECT and CONNECT NAV) and a [[Bose Corporation|Bose]] stereo system were available, the stereo system could now also be operated via buttons on the steering wheel. Also, the ''Selespeed'' gearbox control system was updated, buttons on the steering wheel were replaced by paddle shifters, as seen on the earlier [[Alfa Romeo 147]]. In the center console, the designers added a multifunctional display with [[trip computer]], fault, and service monitor.

The upgrade also included [[electronic stability control]] VDC (Vehicle Dynamic Control) with an emergency brake assist device and slip control [[Traction control system|ASR]] (Anti Slip Regulation) came as standard. Additionally, an MSR (Motor Schleppmoment Regelung) was added to the car, this device prevents wheel skidding by restoring torque to the engine for example when the gear is shifted down abruptly under conditions of low grip. Passive safety was also made better, all versions got window [[airbag]]s as standard. The 2.0&nbsp;L ''[[JTS engine|JTS]]'' {{cvt|165|PS|kW}} engine with [[gasoline direct injection]] replaced the 2.0-litre Twin Spark engine, offering more low end torque and more power than the Twin Spark. The diesel engines were also uprated. The only notable difference exterior-wise was body-coloured mirrors and bumper strips which were earlier black.

===2003 facelift (second series)===
Late 2003 saw the launch of a facelifted 156, with new front and rear [[Fascia (car)|fascias]] designed by [[Giorgetto Giugiaro]].<ref name="www.alfaromeopress.com/">{{cite web |url=http://www.alfaromeopress.com/press/article/330|title= New Alfa 156 and Alfa Sportwagon |access-date=5 February 2009|website=alfaromeopress.com |archive-url=https://web.archive.org/web/20160306202527/http://www.alfaromeopress.com/press/article/330 |url-status=dead |archive-date=6 March 2016}}</ref> A new top-of-the-line model was added to the line up called TI (Turismo Internazionale) designating a sporty kit, this version was equipped with modified suspension, bigger wheels (215/45 17") and leather-trimmed interior. The GTA models never received the exterior update. Diesel engines underwent a major overhaul which included a new four-valve per [[cylinder head]]s and a second stage common rail injection with 1400 bar maximum injection pressure with up to five injections per cycle for lower noise, consumption, and higher performance. They were rated at 140/150&nbsp;PS (103/110&nbsp;kW) for [[straight-4]] 1.9-litre 16-valve and {{cvt|175|PS|kW}} for [[straight-5]] 2.4-litre 20-valve.

The '''156 GTA''' and '''156 Sportwagon GTA''' were launched at the [[Frankfurt Motor Show#2001|Frankfurt Motor Show]] in September 2001. The GTA was named after the [[Alfa Romeo GTA]] from the 1960s, the letters GTA meaning Gran Turismo Alleggerita ({{langx|en|lightened Grand Tourer}}). Developed alongside the [[Alfa Romeo 147|147 GTA]],<ref name="CCFS">{{Cite web|title=Alfa Romeo 156 Gta Review {{!}} CCFS UK|url=https://www.classiccarsforsale.co.uk/reviews/classic-alfa-romeo-reviews-156-gta|website=www.classiccarsforsale.co.uk|access-date=6 May 2020}}</ref> it was an exclusive high-performance model hand assembled on a dedicated production line separate to the standard 156 models.

Development of the GTA styling models and engineering design was entrusted in early 2000 to [[Stola (automotive company)|Stola]] with styling data provided by Centro Stile. Stola completed six prototypes that were further mechanically assembled by Alfa Romeo. Two of those protypes were presented at the Frankfurt Motor Show.<ref>{{cite web|url=https://www.studiotorino.com/index.php?option=com_content&view=article&id=546:200002-156gta-2&catid=53&lang=en&Itemid=841|title=STUDIOTORINO - 200002_156gta|website=studiotorino.com|access-date=14 September 2022}}</ref>

2,973 berlinas and 1,678 Sportwagons were built until the GTA production stopped in October 2005, as the V6 engine as unable to meet emissions regulations and due to the 156 being replaced by the [[Alfa Romeo 159|159]].<ref name="CCFS"/><ref>{{Cite web|url=https://www.rac.co.uk/drive/car-reviews/alfa-romeo/156/156-gta-2002-2006/|title=Alfa Romeo 156 GTA (2002–2006) used car review|website=www.rac.co.uk|access-date=6 May 2020}}</ref> The GTA was sold in limited numbers, with right-hand drive vehicles holding a premium over left-hand drive vehicles due to their rarity.

The very first GTA was sold via online auction, from 13 to 23 September, the duration of the Frankfurt Motor Show.

This engine is praised universally for its sound and revving capabilities.<ref>EVO Magazine August 2011 page 77</ref> This was the largest iteration of the engine built by Alfa Romeo. The engine has a {{cvt|93|mm|in}} bore and a {{cvt|78|mm|in}} stroke, displacing at {{cvt|3179|cc}}. It was rated at {{cvt|250|PS|kW hp|0}} and {{cvt|300|Nm|0}} of torque. Overall, the car weighed {{cvt|55|kg|lb|0}} more than the standard V6 156.<ref>{{Cite web|title=Alfa Romeo 156 GTA: Unsung Hero | first = Chris | last = Rees | work = PistonHeads|url= https://www.pistonheads.com/news/euro-cars/alfa-romeo-156-gta-unsung-hero/31912| access-date=6 May 2020}}</ref>

The GTA variants shared a common interior with post-facelift 156 variants. The doors, boot lid and bonnet were also shared. All else was unique to the GTA, with the engine specifically made by [[Fiat]] and [[Maserati]] Research Centres.<ref name="www.alfaromeopress.com"/>

The GTA did not receive the [[Giorgetto Giugiaro|Giugiaro]] designed facelift introduced on the 156 in 2003, but continued with the acclaimed [[Walter de Silva]] design to the very end of production.

The steering was also made faster, only 1.7 turns from lock to lock compared to 2.1 in normal models. The GTA had also larger brakes ([[Brembo]]), at front {{convert|305|mm|in}} discs and rear {{convert|276|mm|in}}. The front discs were later upgraded to {{convert|330|mm|in}} to cope with the performance potential.

===156 Sportwagon Q4===
In 2004 '''Sportwagon Q4''', an [[all-wheel drive]] version of the Sportwagon was launched in some markets. The Q4 (short for Quadrifoglio 4) system used three differentials, the central one being of the [[Torsen]] C [[Limited slip differential|limited slip]] type; it added about {{cvt|150|kg|lbs|0}} to the vehicle weight. [[Graziano Trasmissioni]], the Turin-based transmission specialist, developed this system.<ref>{{cite web|url=https://www.autonews.com/article/20040223/SUB/402230756/2004-geneva-auto-show-cooked-under-pressure|title=2004 GENEVA AUTO SHOW: Cooked under pressure|access-date=2 July 2019|date=23 February 2004|website=autonews.com}}</ref> A raised ride height meant the Sportwagon Q4's was {{cvt|1458|mm|in|1}} tall. Other than the ride height, special 5-spoke 17-inch wheels and a "Q4" badge on the tail set the Sportwagon Q4 apart from the front-wheel drive 156 versions. The Sportwagon Q4 was only available on [[Left- and right-hand traffic|LHD]] markets, with no [[Left- and right-hand traffic|RHD]] models being built or sold. The only available engine was the 1.9 M-Jet diesel with {{cvt|150|PS|kW hp|0}}.

===156 Crosswagon Q4===
[[File:2005-03-04 Motorshow Geneva 150.JPG|thumb|right|156 Crosswagon Q4]]

The '''Crosswagon Q4''' was launched in 2004 with a [[Crossover (automobile)|crossover]] look and enhanced off-road capabilities. The Crosswagon's ride height was raised further compared to the Sportwagon Q4, giving the car better [[approach and departure angles]]; at {{cvt|1497|mm|in|1}}<ref name="alfa.co.nz">{{cite web |url=http://www.alfa.co.nz/News/Archives/News_2004/Vehicles/Alfa_156/Alfa_Romeo_takes_to_the_Alps/MenuId/293.aspx |title=Alfa Romeo takes to the Alps in Switzerland with the Alfa 156 Crosswagon |access-date=25 April 2007 |website=alfa.co.nz |archive-url=https://web.archive.org/web/20120207001357/http://www.alfa.co.nz/News/Archives/News_2004/Vehicles/Alfa_156/Alfa_Romeo_takes_to_the_Alps/MenuId/293.aspx |archive-date=7 February 2012 |url-status=dead }}</ref> it was {{cvt|6.5|cm|in|1}} taller than a standard 156. Tall-sidewall [[Tire#All season|all-season tyres]] on 17 inch wheels were standard. The only available engine was 1.9 M-Jet diesel rated at {{cvt|150|PS|kW hp|0}}. The Crosswagon was made to look more like an all-terrain vehicle by unique front and rear bumpers and door sills with steel inserts. After the introduction of the [[Alfa Romeo 159|159]] in 2005 the Crosswagon remained in production, and in 2007 it was the last 156 model to be discontinued.

==Specifications==

===Platform and suspension===
The 156 uses a platform derived from the [[Alfa Romeo 155]], (together with [[Fiat Bravo and Brava|Fiat Bravo/Brava]][[Fiat Marea|/Marea]]), which in turn was derived from the Fiat Group's "Tipo" (Also known as C1) platform. However, it is sufficiently different from the original "Tipo" one to be seen as a new platform.<ref name="fiat-tipo-portugal.com">{{cite web|url=http://fiat-tipo-portugal.com/curiosidades.htm |title=Tipo's derivatives |access-date=24 July 2007 |website=fiat-tipo-portugal.com |archive-url=https://web.archive.org/web/20120305183446/http://fiat-tipo-portugal.com/curiosidades.htm |archive-date=5 March 2012 |url-status=dead }}</ref><ref name="alfaworkshop.co.uk">{{cite web|url=http://www.alfaworkshop.co.uk/alfa_romeo_156.shtml |title=Alfa Romeo 156 |access-date=24 July 2007 |website=alfaworkshop.co.uk |archive-url=https://web.archive.org/web/20111227103908/http://www.alfaworkshop.co.uk/alfa_romeo_156.shtml |archive-date=27 December 2011 |url-status=live }}</ref> This version of the C1 (Type 2) platform has significant modifications to its suspension, chassis, and rigidity, making it not a simple "clone" or "rebadge" of the Bravo/Brava. The 156 is a highly developed [[front-wheel drive]] car; (the Cross/Sportwagon Q4 offered [[four-wheel drive]] in [[left-hand drive]] markets) with a double high [[Control arm|wishbone]] front suspension and updated version of [[MacPherson strut|MacPherson]] type rear suspension,<ref name="alfaromeopress.com" /><ref name="156-156Sportwagon 2004 Brochure">{{cite web|url=http://australiancar.reviews/_pdfs/AlfaRomeo_156-156Sportwagon_1999-III_Brochure_200402.pdf|title=2004 Brochure |access-date=2 November 2018}}</ref> which consists of a telescopic vertical strut with coaxial spring and two transverse links of different lengths and a longitudinal strut. This structure means that the rear wheels have a tiny [[Steering#Four-wheel steering|passive steering]] ability.<ref name="italiaspeed"/> Weight saving materials (mainly aluminium) have been used in several parts both front and rear suspension.

For the 156 GTA, weight saving materials were also used in many other parts like magnesium framed front seats and dashboard frame. The 156 GTA only shared common parts with other 156 variants with respect to the facelift interior, doors, bonnet and boot lid.<ref name="goauto.com.au">{{cite web|url=http://www.goauto.com.au/mellor/mellor.nsf/story2/A9487CD80711A695CA2569E7001DEDE9 |title=Alfa Romeo / 156 / Twin Spark sedan |access-date=7 January 2007 |website=goauto.com.au |archive-url=https://web.archive.org/web/20120410084533/http://www.goauto.com.au/mellor/mellor.nsf/story2/A9487CD80711A695CA2569E7001DEDE9 |archive-date=10 April 2012 |url-status=live }}</ref>

==Use in law enforcement==
The Alfa 156 sedan and the station wagon were widely used by the Italian and other police and other law enforcement forces. In Italy it was used by [[Carabinieri]], [[Polizia di Stato]], [[Polizia provinciale]], [[Polizia Penitenziaria]] and [[Guardia di Finanza]]. Subsequently, the 156 was replaced by the more modern Alfa Romeo 159.
