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'''. 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 [[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. The lower powered versions only have variable cam phasing on the inlet cam. Selected models also include variable intake. The engine weighs {{convert|370|lb|abbr=on}} as installed. | |||

== 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 {{Convert|600|hp|kW|0|abbr=on}} and {{auto ftlbf|540}} of torque. Development of the engine was reportedly being conducted in Australia by Holden. <ref name=AutoweekPR20070321>{{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= | accessdate=2009-01-04}}</ref> | |||
In August, 2008, GM announced that development of the V12 had been canceled. The CAFE standards are most likely to blame. <ref name=autospies20080821>{{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]] | accessdate=2009-01-04}}</ref> | |||
