The LW2 engine was based on the low-output LE0 V6. The dual fuel 235 hp (175 kW 238 PS) LW2 version was able to run on petrol and autogas. Catharines (Ontario), Flint Engine South (Michigan), Melbourne (Australia), Ramos Arizpe (Mexico), and Sagara (Japan) by Suzuki. This engine is produced in several locations: St. The engine weighs 370 lb (170 kg) as installed. Selected models also include variable exhaust. Lower powered versions only have variable cam phasing on the inlet cam (LE0). The 3.6 L 217.5 cu in (3,564 cc) LY7 engine was developed primarily by Holden and introduced in the 2004 Holden Commodore and 2004 Cadillac CTS sedan. Output is identical to the LF1.ġ68 kg (370 lb) (3.6 V6 High Feature engine) The LFW is a flexible fuel version of the LF1, capable of running on E85, gasoline, or any mixture of the two. The LF1 is a 3.0-litre (2,994 cc) version with a bore and stroke of 89 mm × 80.3 mm (3.50 in × 3.16 in) produced between 20 equipped with spark ignition direct injection (SIDI) and a 11.7:1 compression ratio. In 2011, production of the Cadillac SRX with the LAU engine ceased, but the engine remained in use in the Saab 9-4X until 2012, when production of that model came to an end. The LAU is GM's new code for the LP9 Turbo engine, its usage starting with the 2010 Cadillac SRX. 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. 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. It has the same bore and stroke as the naturally aspirated LP1, however the compression ratio is reduced to 9.5:1. The LP9 is a 2.8 L turbocharged version used for the Saab 9-3, Saab 9-5 and other GM vehicles. This engine is also known as a A28NET, Z28NET, Z28NEL or B284. It has a 89 mm × 74.8 mm (3.50 in × 2.94 in) bore and stroke, sequential multi-port fuel injection and a 10.0:1 compression ratio. It was also used on the Chinese 2008 CTS. ![]() Holden had the job of developing smaller engines (Holden 3.2, LP1 and Saab 2.8, LP9 Turbo) as well as their own Holden 3.6 and 3.0 HFV6 (called the Alloytec V6) for local models.Ĭadillac and Holden both tested variations of these engines in the United States and Australia.Ī 2.8 L (2,792 cc) LP1 variant was introduced in the 2005 Cadillac CTS. 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. The HFV6 was designed, tested and produced in a joint program by Holden and Cadillac. GM's Australian auto division Holden produced a HFV6 engine under the name "Alloytec". 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. 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. Most versions feature continuously variable cam phasing on both intake and exhaust valves and electronic throttle control. It is a 60° 24-valve design with aluminum block and heads and sequential multi-port fuel injection. The series was introduced in 2004 with the Cadillac CTS and the Holden Commodore (VZ). 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.
