GM announces new turbocharged 2.8 litre V-6 engine

Detroit, Michigan – General Motors announced a new 2.8 litre turbocharged V6 engine,

The global V-6 engine family also includes a 2.8L V-6 VVT normally aspirated version
which debuted in the 2005 Cadillac CTS, as well as a 3.6L V-6 VVT version that also

and SRX, as well as the Buick Rendezvous and LaCrosse. It is available under the
Alloytec brand name in the 2005 Holden Commodore, Calais, Berlina short wheelbase,
Statesman and Caprice long wheelbase, Ute, Cab Chassis and Crewman. All use variable
valve timing for optimal performance and emissions control.

The 2.8L V-6 Turbo is built at Holden’s Port Melbourne, Australia facility, along
with 3.6L variants of the global V-6.
