The ''' | The '''3600 LY7''' (and derivative '''LP1''') are members of [[General Motors Corporation|General Motors]]' new '''High Feature''' (or '''HFV6''') engine family of modern [[DOHC]] [[V6]]s. This new family of engines was introduced in 2004 with the [[Cadillac CTS]]. [[Holden]] sells the HFV6 under the name '''Alloytec'''.

It is a 60° 24-valve design with aluminum block and heads and [[Fuel injection|Sequential Electronic 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, forged connecting rods, a [[VLIM|variable intake manifold]], twin knock control sensors and coil-on-plug ignition. It was developed by the same international team responsible for the [[GM Ecotec engine|Ecotec]], including the [[Opel]] engineers responsible for the [[GM 54-Degree V6 engine|54° V6]], with involvement with design and development engineering from Ricardo, Inc. | |||
High Feature V6 engines are produced at Fisherman's Bend in [[Port Melbourne]], [[Australia]], [[St. Catharines]] in [[Canada]], and [[Flint Engine South]] in [[Flint, Michigan]], [[United States]]. | |||
== 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 Catherines). Holden had the job of developing smaller engines (Holden 3.2, LP1 and LP9 Turbo)<!-- Not sure how to include an internal link --> as well as their own Holden 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. | |||
== Alfa Romeo == | |||
[[Alfa Romeo]] uses the High Feature engine design, though with many modifications, as the [[JTS engine|JTS]] V6. The Alfa unit features lean-burn technology as on many other engines from the company. It displaces 3.2 L (3195 cc) and has an output of {{convert|256|hp|kW PS|lk=on|abbr=on}} at 6200 rpm and {{convert|237|ftlbf|Nm|abbr=on|lk=on}} torque, with [[gasoline direct injection]] allowing a high [[compression ratio]] of 11.25:1. The engine is also equipped with cam-phasing on both inlet and exhaust side, thus the name "TwinPhaser". | |||
Alfa Romeo only acquires the core designs and productions of the HFV6. It is then taken to their factory and modified for their performance, fuel economy and soundtrack. | |||

The 3.6 L (3564 cc) '''LY7''' version was introduced in the 2004 [[Cadillac CTS]] sedan. It has a 10.2:1 compression ratio and produces {{Convert|255|hp|kW|0|abbr=on}} at 6200 rpm and {{auto ftlbf|252}} at 3100 rpm. The bore is 3.70 in (94.0 mm) and the stroke is 3.37 in (85.6 mm). In some applications, including the [[Buick LaCrosse]] and [[Holden Commodore]], the LY7 has an output of 235 to 262 hp (175 to 195 kW) and 225 to 251 ft·lbf (305 to 340 N·m) depending on the vehicle induction and exhaust system designs.

Manufacturer | General Motors |
---|---|
Also called | Alloytec V6 |
Type | DOHC 60° 24-valve V6 |
Production | 2004– |
Predecessor | 54° V6 |
Dry weight | 168 kg (370 lb) (3.6 V6 High Feature engine) |
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 pasing 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, 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, Inc.
High Feature V6 engines are produced at Fisherman's Bend in Port Melbourne, Australia, St. Catharines in Canada, and Flint Engine South in Flint, Michigan, United States.
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 Catherines). Holden had the job of developing smaller engines (Holden 3.2, LP1 and LP9 Turbo) as well as their own Holden 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.
Alfa Romeo
Alfa Romeo uses the High Feature engine design, though with many modifications, as the JTS V6. The Alfa unit features lean-burn technology as on many other engines from the company. It displaces 3.2 L (3195 cc) and has an output of 256 hp (191 kW; 260 PS) at 6200 rpm and 237 ft·lbf (321 N·m) torque, with gasoline direct injection allowing a high compression ratio of 11.25:1. The engine is also equipped with cam-phasing on both inlet and exhaust side, thus the name "TwinPhaser".
Alfa Romeo only acquires the core designs and productions of the HFV6. It is then taken to their factory and modified for their performance, fuel economy and soundtrack.
Applications:
- 2005 Alfa Romeo 159
- 2006 Alfa Romeo 159 Sportwagon
- 2005 Alfa Romeo Brera
- 2006 Alfa Romeo Spider
Holden 3.2
Holden has built its own 3.2 L version of the High Feature engine in Australia. Branded with the Alloytec name like the 3.6 L version, this version produces 227 hp (169 kW) at 6600 rpm and 219 lb·ft (297 N·m) at 3200 rpm.
Applications:
- 2007 Holden Captiva
- 2007 Opel Antara
LY7
The 3.6 L (3564 cc) LY7 version was introduced in the 2004 Cadillac CTS sedan. It has a 10.2:1 compression ratio and produces 255 hp (190 kW) at 6200 rpm and 252 lb·ft (342 N·m) at 3100 rpm. The bore is 3.70 in (94.0 mm) and the stroke is 3.37 in (85.6 mm). In some applications, including the Buick LaCrosse and Holden Commodore, the LY7 has an output of 235 to 262 hp (175 to 195 kW) and 225 to 251 ft·lbf (305 to 340 N·m) depending on the vehicle induction and exhaust system designs. The lower powered versions only have variable cam phasing on the inlet cam. Selected models also include variable intake. The engine weighs 370 lb (170 kg) as installed.
This engine is produced in North America and Australia.
On the Lambda crossover SUVs (Saturn Outlook, GMC Acadia, and Buick Enclave) it produces 275 hp (205 kW) and 251 lb·ft (340 N·m). The Holden Alloytec version has been modified to meet Euro III emissions standards and has an output of 262 hp (195 kW) and 251 ft-lbf (340 N-m). A dual fuel 235 hp (175 kW) version able to run on petrol and autogas (LPG) has also been produced by Holden in Australia.

- 2007 Suzuki XL-7
V12
On March 21, 2007 it was reported by AutoWeek that GM is planning to develop a 60-degree V12 based on this engine family to power the top version of Cadillac's upcoming flagship sedan. This engine would essentially consist of two 3.6 L High Feature V6s attached end-to-end on a single crankshaft, and would feature such high-end technologies as direct injection and cylinder deactivation. If so, the engine would displace 7.2 liters, and produce 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. [11]
In August, 2008, GM announced that development of the V12 had been canceled. The CAFE standards are most likely to blame. [12]
