GM High Feature engine
The GM High Feature engine is a family of modern DOHC V6 engines produced by General Motors. The series was introduced in 2004 with the Cadillac CTS and the Holden VZ Commodore.
It is a 60° 24-valve design with aluminum block and heads and sequential multi-port 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-length 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.
GM's Australian auto division Holden produced a HFV6 engine under the name "Alloytec."
History
The HFV6 was designed, tested, and produced in a joint program by Holden and Cadillac. A majority of designs into the new alloy construction, transmission pairing, and first use in production were all undertaken in Detroit. Holden was charged with developing smaller engines as well as their own Holden 3.6 and 3.0 HFV6 for local models.Cadillac and Holden both tested variations of these engines in the United States and Australia.

It has the same bore and stroke as the naturally aspirated LP1, however the compression ratio is reduced to 9.5:1. The engine is manufactured at Holden's Fishermans Bend engine factory in Port Melbourne, Australia, while GM Powertrain Sweden is responsible for turbocharging the engine. 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.
