The '''GM High Feature engine''' (also known as the '''HFV6''', and including the '''3600 LY7''' and derivative '''LP1''') is a family of modern [[DOHC]] [[V6 engine]]s produced by [[General Motors]]. The series was introduced in 2004 with the [[Cadillac CTS]] and the [[Holden Commodore (VZ)|Holden VZ Commodore]].

It is a 60° 24-valve design with aluminum block and heads and [[sequential multi-port fuel injection]]. Most versions feature [[Continuous variable valve timing|continuously variable cam phasing]] on both intake and exhaust valves and [[electronic throttle control]]. Other features include piston oil-jet capability, forged and [[Deep Rolling|fillet rolled]] [[crankshaft]], sinter forged [[connecting rod]]s, a [[VLIM|variable-length intake manifold]], twin knock control sensors and [[Direct Ignition#Direct ignition|coil-on-plug ignition]]. It was developed by the same international team responsible for the [[GM Ecotec engine#Ecotec|Ecotec]], including the [[Opel]] engineers responsible for the [[General Motors 54° V6 engine|54° V6]], with involvement with design and development engineering from [[Ricardo plc]].{{cn|date=January 2024}}

GM's Australian auto division [[Holden]] produced a HFV6 engine under the name "[[#Holden High Feature engine|Alloytec]]."

== History ==
The HFV6 was designed, tested, and produced in a joint program by [[Holden]] and [[Cadillac]].{{cn|date=January 2024}} A majority of designs into the new alloy construction, transmission pairing, and first use in production were all undertaken in Detroit (and manufactured in [[St. Catharines, Ontario]]). Holden was charged with developing smaller engines (Holden 3.2 LP1 and Saab 2.8 Turbo LP9) as well as their own Holden 3.6 and 3.0 HFV6 (called the [[#Holden High Feature engine|Alloytec]] V6) for local models.

Cadillac and Holden both tested variations of these engines in the United States and Australia.

== 2.8 ==
=== LP1 ===
A {{convert|2792|cc|L|1|order=flip|abbr=on}} ''LP1'' variant was introduced in the 2005 [[Cadillac CTS]]. It was also used on the Chinese 2008 CTS. It has a {{convert|89x74.8|mm|in|2|abbr=on}} bore and stroke, [[sequential multi-port fuel injection]] and a 10.0:1 compression ratio. The ''LP1'' was built in St. Catharines, Ontario.

[[File:2006 Saab 9-3 SportCombi engine.jpg|right|thumb|250px|2.8&nbsp;L turbo V6 in a 2006 [[Saab 9-3]]]]

''This engine is also known as a A28NET, Z28NET, Z28NEL or B284.''

The ''LP9'' is a 2.8L [[Turbocharger|turbocharged]] version used for the [[Saab 9-3]], [[Saab 9-5]], and other GM vehicles. It has the same bore and stroke as the [[naturally aspirated]] [[#LP1|LP1]], however the compression ratio is reduced to 9.5:1. The engine is manufactured at Holden's Fishermans Bend engine factory in Port Melbourne, Australia, while GM Powertrain Sweden (formerly Saab Automobile Powertrain) is responsible for turbocharging the engine. Global versions of this engine use the same horsepower rating for both metric and imperial markets – [[Horsepower#Mechanical horsepower|mechanical horsepower]] – while the Europe-only versions are rated in [[Pferdestärke|metric horsepower]].

The {{convert|3564|cc|L cuin|1|order=flip|abbr=on}} ''LY7'' engine was developed primarily by [[Holden]] and introduced in the 2004 [[Holden Commodore (VZ)|Holden VZ Commodore]] and 2004 [[Cadillac CTS]] sedan. It has a 10.2:1 compression ratio, Sequential multi-port fuel injection, and a bore and stroke of {{convert|94x85.6|mm|in|2|abbr=on}}. Lower-powered versions only have variable cam phasing on the inlet cam (LE0). Selected models also include variable exhaust. The engine weighs {{convert|370|lb|kg|abbr=on}} as installed.

This engine is produced in several locations: St. Catharines (Ontario), Flint Engine South (Michigan), Melbourne (Australia), Ramos Arizpe (Mexico), and Sagara (Japan) by Suzuki.

Suzuki's engine designation is ''N36A''.

The dual-fuel {{convert|235|hp|kW PS|0|abbr=on}} ''LW2'' version was able to run on petrol and [[autogas]]. The LW2 engine was based on the low-output LE0 V6. It featured a factory-fitted dual-fuel system developed by IMPCO, different valves, and hardened titanium valve seats. This motor was available exclusively in Holden vehicles from 2005–2012.

=== LLT ===
The {{convert|3564|cc|L|1|order=flip|abbr=on}} ''LLT'' is a direct injected version based on the earlier LY7 engine. It was first unveiled in May 2006, and the DI version was claimed to have 15% greater power, 8% greater torque, and 3% better [[Fuel economy in automobiles|fuel economy]] than its port-injected counterpart. The ''LLT'' engine has a [[compression ratio]] of 11.3:1, and has been certified by the [[Society of Automotive Engineers|SAE]] to produce {{convert|302|hp|kW PS|0|abbr=on}} at 6300 rpm and {{convert|272|lbft|Nm|0|abbr=on}} of torque at 5200 rpm on regular unleaded (87 octane) gasoline.

=== LWR ===
The ''LWR'' is dedicated LPG 3.6-liter engine. Introduced in the MY 2012 [[Holden Commodore (VE)#Series II|Holden VE Commodore]], Based on the 3.6-litre LY7 engine, the LWR had a vapour injection system. The vapour injection system injected gas directly into the [[air intake]] runner, thereby preventing excess gas from circulating through the air intake system. Although liquid LPG injection generally produces more power, [[Holden]] justified vapour injection on the grounds of lower fuel consumption, lower {{CO2}} emissions, reduced pumping and parasitic losses, and start-up reliability in hot weather.

The dedicated LPG LWR engine produced peak power and torque of {{convert|180|kW|PS hp|0|abbr=on}} at 6000 rpm and {{convert|320|Nm|lbft|0|abbr=on}} at 2000 rpm. The LWR engine was mated to GM's six-speed [[GM 6L50 transmission|6L45]] [[automatic transmission]] and, over the combined ADR 81/02 test cycle, the Commodore Omega achieved fuel consumption of {{convert|11.8|L/100 km|abbr=on}} – an improvement of 1.6 L/100 km compared to its dual-fuel LW2 predecessor. Furthermore, the LWR engine exceeded [[European emissions standards|Euro 6 emissions standards]].
* Specially hardened valves and valve seats.
* A redesigned cylinder head and manifold for improved air flow.
* Variable exhaust valve timing (the LW2 engine only had variable intake valve timing)
* Specially-developed fuel injectors.
* New pistons with pentroof-style centre-domes and valve eyelets for a higher compression ratio of 12.2:1 (compared to 10.2:1 for the dual fuel engine).
* A new fuel rail and a new LPG fuel filter.

=== LF4 ===
The ''LF4'' is a higher-performance variant of the LF3 for use in the [[Cadillac V-Series#ATS-V|Cadillac ATS-V]] and [[Cadillac CT4#CT4-V Blackwing|Cadillac CT4-V Blackwing]]. Changes to the LF3 include:
* Turbochargers with low-inertia titanium-aluminide turbines and vacuum-actuated wastegates for more responsive torque production
* Compressors matched for peak efficiency at peak power levels, for optimal track performance
* Patent-pending low-volume charge-cooling system that optimizes packaging efficiency and maximizes boost pressure
* To compliment the quick spooling turbochargers, lightweight titanium connecting rods that reduce inertia of the rotating assembly were used on all ATS-V models, while only manual transmission CT4-V Blackwing models featured titanium connecting rods. 10-speed automatic CT4-V Blackwing models featured steel connecting rods.<ref name="TitaniumRods">{{cite web |title=Only Some Cadillac CT4-V Blackwing Engines Have Titanium Rods |url=https://gmauthority.com/blog/2021/04/only-some-cadillac-ct4-v-blackwing-engines-have-titanium-rods/ |website=GM Authority |publisher=GM |date=April 2021 |access-date=30 March 2025}}</ref>

== 7.2L V12 ==
On March 21, 2007, ''[[AutoWeek]]'' reported that GM was planning to develop a 60-degree [[V12 engine|V12]] based on this engine family to power the top version of Cadillac's upcoming flagship sedan. This Cadillac would essentially have had two 3.6L High Feature V6s attached crankshaft-to-crankshaft and would have featured high-end technologies including [[Direct fuel injection|direct injection]] and [[cylinder deactivation]]. If this engine were developed, it would have displaced 7.2 liters, and produced approximately {{Convert|600|hp|kW PS|0|abbr=on}} and {{convert|540|lbft|Nm|0|abbr=on}} of torque. Development of the engine was reportedly being conducted in Australia by Holden, with a potential HSV or Statesman application.<ref name=AutoweekPR20070321>{{cite press release | title = AutoWeek Breaks Major Cadillac News in March 26 Issue | publisher = prnewswire.com | date= 2007-03-21 | url = http://www.prnewswire.com/cgi-bin/stories.pl?ACCT=104&STORY=/www/story/03-21-2007/0004550743&EDATE= | access-date=2009-01-04}}</ref>

In August 2008, GM announced that development of the V12 had been cancelled.<ref name=autospies20080821>{{cite news | title=Cadillac cancels plans for V12 XLKS flagship sedan | work=autospies.com | url=http://www.autospies.com/news/Cadillac-cancels-plans-for-V12-XLKS-flagship-sedan-33871 | date=2008-08-21 | access-date=2009-01-04}}</ref>

==Timing chain issues==
Earlier production 2.8L, 3.0L, 3.2L, and 3.6L engines with the three chain design suffered from premature timing chain failures because of a faulty PCV system and extended oil change intervals. Most of the problems occurred on pre-LFX engines.<ref>{{Cite web|url=https://www.motor.com/magazine-summary/gm-3-6l-engine-problems-eye-electronics-november-2013|title = MOTOR}}</ref>

==Holden High Feature engine==
{{unreferenced section|date=March 2023}}
[[Holden]] sold a HFV6 engine under the name '''Alloytec'''. The High Feature moniker on the Holden produced engine is reserved for the twin cam phasing high output version. The block was designed to be expandable from 2.8&nbsp;L to 4.0&nbsp;L. High Feature V6 engines were previously produced in Fishermans Bend, [[Port Melbourne]], [[Australia]], and remain in production at the following four manufacturing locations: [[St. Catharines Engine Plant]], [[St. Catharines]], [[Canada]]; [[Flint Engine South]] in [[Flint, Michigan]], [[United States]]; [[Romulus Engine|Romulus Engine Plant]] in [[Romulus, Michigan]]; and [[Ramos Arizpe Assembly|Ramos Arizpe, Coahuila, Mexico]]. The assembly lines for the St. Catharines and Flint facilities were manufactured by Hirata Corporation at its powertrain facility in [[Kumamoto, Japan]]. Most of the designs of this motor happened in Flint. They were first produced for the Cadillac range.{{cn|date=March 2023}} The engine block and cylinder heads are cast at [[Defiance Foundry]] in [[Defiance, Ohio]].
