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 engines produced by General Motors. The series was introduced in 2004 with the Cadillac CTS and the Holden Commodore (VZ).

It is a 60° 24-valve design with aluminum block and heads and sequential multi-port fuel injection. Most versions feature continuously variable cam phasing on both intake and exhaust valves and electronic throttle control. Other features include piston oil-jet capability, forged and fillet rolled crankshaft, sinter forged connecting rods, a variable-length intake manifold, twin knock control sensors and coil-on-plug ignition. It was developed by the same international team responsible for the Ecotec, including the Opel engineers responsible for the 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 "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 Alloytec V6) for local models.

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

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]]

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

The LP9 is a 2.8L 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, 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 – mechanical horsepower – while the Europe-only versions are rated in metric horsepower.

= LWR =

The LWR is dedicated LPG 3.6-liter engine. Introduced in the MY2012 Holden 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 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 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.

Starting with the 2016 Cadillac models, a new generation of High Feature V6s were developed.{{cite web|url=http://media.cadillac.com/media/us/en/cadillac/news.detail.html/content/Pages/news/us/en/2015/mar/0320-cadillac/0320-cadillac-36l.html|access-date=5 April 2015|title=All-New, Advanced 3.6L V-6 to Drive Cadillac CT6|date=20 March 2015}} These new engines have redesigned block architectures with bore centers increased from {{convert|103|mm|in|abbr=on|sigfig=4}} on prior HFV6 engines to {{convert|106|mm|in|abbr=on|sigfig=4}} and a redesigned cooling system to target the hottest areas while also facilitating faster warm-up. They also incorporate engine start-stop technology, cylinder-deactivation, 2-stage oil pumps, and updated variable valve timing featuring intermediate park technology for late-intake valve closure. Both engines debuted in the 2016 Cadillac CT6.{{cite web|title=Cadillac Next-Gen V-6 Engines Led by 3.0L Twin Turbo|url=http://media.gm.com/media/us/en/gm/news.detail.html/content/Pages/news/us/en/2015/mar/0320-cadillac/0320-cadillac-twin-turbo.html|website=GM Media USA|date=20 March 2015|publisher=GM|access-date=20 March 2015}}

Chevrolet Colorado

7.2L V12

On March 21, 2007, AutoWeek reported that GM was planning to develop a 60-degree 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 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.{{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}}

In August 2008, GM announced that development of the V12 had been cancelled.{{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}}

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.{{Cite web|url=https://www.motor.com/magazine-summary/gm-3-6l-engine-problems-eye-electronics-november-2013|title = MOTOR}}

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 L to 4.0 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 Plant in Romulus, Michigan; and 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.
