The 3600 LY7 (and derivative LP1) are members of General Motors' new High Feature (or HFV6) engine family of modern DOHC V6s. This new family of engines was introduced in 2004 with the Cadillac CTS. Holden sells the HFV6 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.
It is a 60° 24-valve design with aluminum block and heads and Sequential Electronic 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 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.
High Feature V6 engines are produced at Fishermans Bend in Port Melbourne - Australia, St. Catharines in Canada, and Flint Engine South in Flint, Michigan - United States. The assembly lines for the St. Catharines and Flint, Michigan facilities were manufactured by Hirata Corporation at their powertrain facility in Kumamoto, Japan.
History
The HFV6 was first designed, tested and produced in a joint team by Cadillac and Holden. A majority of design into the new alloy construction, transmission pairing and first use in production were all undertaken in Detroit (and manufactured in St. Catharines). Holden had the job of developing smaller engines (Holden 3.2, LP1 and LP9 Turbo) as well as their own Holden 3.6 HFV6 (called the Alloytec V6) for local models.
Cadillac and Holden both tested variations of these engines in US and Australia. North America and Australia remain the only two places that manufacture the HFV6.

LP1
A 2.8 L (2792 cc) LP1 variant was introduced in the 2005 Cadillac CTS. It has a 89.0 mm (3.50 in) bore, a 74.8 mm (2.94 in) stroke, and a 10.0:1 compression ratio. The LP1 was built in Saint Catharines, Ontario.
Applications:
| Year(s) | Model | Power | Torque |
|---|---|---|---|
| 2005–2007 | Cadillac CTS | 210 hp (157 kW) @ 6500 rpm | 194 lb⋅ft (263 N⋅m) @ 3300 rpm |
LP9
This engine is also known as a A28NET, Z28NET or B284.
The LP9 is a 2.8 L turbocharged version used for the Saab 9-3 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. GM Powertrain Sweden (Saab Automobile Powertrain) was responsible for turbocharging the engine and it is built in Port Melbourne, Australia. Note that 'global' versions use the same horsepower rating for both metric and imperial markets (using imperial horsepowers) while Europe only versions are rated in metric horsepowers. Max torque are without torque limits used in some versions.

LLT
The 3.6 litre (3564 cc) 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 percent greater power, 8 percent greater torque, and 3 percent better fuel economy than its port-injected counterpart. The LLT engine has a compression ratio of 11.3:1, and has been certified by the SAE to produce 302 horsepower (225 kW) at 6300 rpm and 272 lb⋅ft (369 N⋅m) of torque at 5200 rpm on regular unleaded (87 octane) gasoline. This engine debuted on the 2008 Cadillac STS and CTS.[8][9] GM will use a LLT in all 2009 Lambda-derived crossover SUVs to allow class-leading fuel economy in light of the new Corporate Average Fuel Economy (CAFE) standards. In the Lambdas, LLT engine produces 288 horsepower (215 kW) and 270 lb⋅ft (366 N⋅m) of torque.[10][11][12]

LFX
The LFX is an enhanced version of the LLT engine. Introduced in the MY2012 Chevrolet Camaro LS, it is 20.5 pounds (9.3 kg) lighter than the LLT, due to a redesigned cylinder head and integrated exhaust manifold, and composite intake manifold. Other components like the fuel injectors, intake valves, and fuel pump have also been updated. Power and torque are up slightly from the LLT. The compression ratio is 11.5:1. The LFX also features E85 flex-fuel capability.

LCS
The 3.6 litre (3564 cc) LCS is derived from the direct-injected LLT for use in hybrids, using the two-mode system.[13] Differences from the LLT include a slightly lower compression ratio, 11.3:1, and lower power and torque peaks. It was to debut in the 2009 Saturn Vue Hybrid, where it would make 262 hp (195 kW) at 6100 rpm and 250 lb⋅ft (339 N⋅m) of torque at 4800 rpm.[14] Fuel economy 6–8 km/liter in city, 9–11 km/liter on highway Applications:

LF3
The 3.6 L twin-turbocharged version for the 2014 Cadillac CTS and 2014 Cadillac XTS has been announced at the 2013 NYAS.[15]
The engine is rated at 420 hp (313 kW) of power @ 5750 rpm and 430 lb⋅ft (583 N⋅m) of torque @ 3500-4500 rpm (with 90% of torque being available at 2500-5500 rpm) and helps the CTS achieve 0-60 mph time of 4.6 seconds with an 8-speed automatic transmission.
In essence, the twin-turbo 3.6L V6 is the force-inducted variant of the popular LFX V6 currently found in the Cadillac ATS, XTS, and SRX, among many other GM models, with several important upgrades, including:
- All-new cylinder block casting
- All-new cylinder head castings
- Strengthened connecting rods
- Forged steel crankshaft
- Continuously variable valve timing
- Large 38.3 mm intake valves and 30.6 mm sodium-filled exhaust valves
- Machined, domed aluminum pistons with top steel ring carrier for greater strength
- 10.2:1 compression ratio
- Patented, integrated charge air cooler system with low-volume air ducts
- Two turbochargers produce more than 12 pounds of boost (80 kPa)
- Vacuum-actuated wastegates with electronic control valves
- All-new direct injection fuel system
- Tuned air inlet and outlet resonators, aluminum cam covers and other features that contribute to exceptional quietness and smoothness.

V12
On March 21, 2007 it was reported by AutoWeek 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 3.6 L High Feature V6s attached crankshaft-to-crankshaft and would have featured such high-end technologies as direct injection and cylinder deactivation. If so, the twin-engine would have displaced 7.2 liters, and produced approximately 600 hp (447 kW) and 540 lb⋅ft (732 N⋅m) of torque. Development of the engine was reportedly being conducted in Australia by Holden.[16]
In August, 2008, GM announced that development of the V12 had been cancelled.[17]
