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 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 crankshaft and 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.


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 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 highcompression 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.

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 Convert|227|hp|kW|0|abbr=on at 6600 rpm and auto ftlbf|219 at 3200 rpm.

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. Selected models also include variable intake. The engine weighs convert|370|lb|abbr=on 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 Convert|275|hp|kW|0|abbr=on and auto ftlbf|251. 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 Convert|235|hp|kW|0|abbr=on version able to run on autogas (LPG) has also been produced by Holden in Australia.

The 3.6 liter (3564 cc) LLT is a direct injected version of the LY7. It was first unveiled in May 2006, and was claimed to have 15 per cent greater power, 8 per cent greater torque, and 3 per cent better fuel economy than its port-injected counterpart. It has a compression ratio of 11.4:1, and has been certified by the SAE to produce convert|302|hp|kW at 6300 rpm and auto ftlbf|272of torque at 5200 rpm on regular unleaded (87 octane) gasoline. This engine debuted on the 2008 Cadillac STS and CTS. [ [http://www.edmunds.c...otopanel..2.*#5 Detroit Auto Show: 2008 Cadillac CTS ] ] [ [http://news.windingr...-rating-to-302/ Uncategorized | NextAutos.com and Winding Road ] ] 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 convert|286|hp|kW and auto ftlbf|255 of torque.

The 3.6 L (3564 cc) LCS is derived from the direct-injected LLT for use in hybrids, using the two-mode system [ [http://eogld.ecomm.g...&page=5&butID=3 Model Information - Online Ordering Guide ] ] . Differences from the LLT include a slightly lower compression ratio, 11.3:1, and lower power and torque peaks. It will debut in the 2009 Saturn Vue Hybrid, where it will make Convert|262|hp|kW|0|abbr=on at 6100 rpm and auto ftlbf|250 of torque at 4800 rpm. [http://media.gm.com/...0Hybrid_SAE.pdf]

LP9 Turbo

The LP9 is a 2.8 L turbocharged version is used for the Saab 9-3 and other GM vehicles. It produces Convert|255|hp|kW|0|abbr=on EEC at 5500 rpm and auto ftlbf|258 between 1800 and 5000 rpm. It has the same bore and stroke as the naturally-aspirated LP1, however the compression ratio is reduced to 9.5:1. There is also other variants available, with Convert|230|hp|kW|0|abbr=onEEC and auto ftlbf|280 EEC. GM Powertrain Sweden (Saab Automobile Powertrain) has been responsible for the turbocharging of the engine. The engine is built in Port Melbourne, Australia.

Suzuki builds the High Feature V6 at its Sagara, Japan plant for the Suzuki XL-7 SUV under license from General Motors. Displacing 3.6 L, this engine produces Convert|252|hp|kW|0|abbr=onat 6500 rpm and auto ftlbf|243 at 2300 rpm.

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 injectionand cylinder deactivation. If so, the engine would displace 7.2 liters, and produce approximately Convert|600|hp|kW|0|abbr=on and auto ftlbf|540 of torque. Development of the engine is reportedly being conducted in Australia by Holden. [http://www.prnewswir...04550743&EDATE=]

не осилил, че это, по русски можно


Это краткая история антаровского дрыгла V6 .Ну там, откуда взялся, куда ставился, где производился, в каких модификациях выпускался.

А я вот без понятия, какой у нас мотор=)

И из перечня тоже не понял.

блок - люминь?

балансирные валы есть?

вариатор фаз тока на впуске или на выпуске тоже?

длина впуска - меняется?

Так там тоже общие слова по 190к-ватный 3,6 литровый мотор. Там я понял, что люминиевый блок и что бывает и переменный коллектор и двойной "ванос". Но такой смысл, что вроде не во всем семействе это все сразу ставится. У нас же нету непосредственного впрыска, который там тоже бывает.

Но я как бы про всё семейство информацией хотел поделиться. Об антантовском варианте все давно в TIS всё узнали.

Все уже тщательно изучили ТИС? )


Не вижу смысла его тщательно изучать, но то что меня интересует, я посмотрел.


Я не понимаю, к чему такой вопрос?
