GM Announces New Direct-Injection Engine Range Photo:

General Motors has improved its fuel-saving credentials by adding a direct-injected 3.0 litre V6 and 2.4 litre inline four to its range of powerplants, both of which deliver more power, greater torque and better fuel economy than their port-injected predecessors.

The direct-injected four-banger will be fitted to the 2010 Chevrolet Equinox crossover and produces 134kW and 232Nm from its 2.4 litres, while the 3.0 litre V6 thumps out a respectable 187kW and 290Nm. The V6 will power the 2010 Equinox, 2010 Buick LaCrosse and 2010 Cadillac SRX.


Direct injection uses less fuel than the more traditional port injection to create the same amount of power and torque, while higher compression ratios and greater combustion efficiency help deliver reduced emissions. By GM?s estimates, the application of direct injection will save drivers of the 2.4 litre Equinox 507 litres of petrol over 24,140km.


But despite the obvious environmental and fuel-saving benefits of direct-injection technology, GM?s local arm Holden has yet to apply such tech to the home-grown Commodore range. It?s not like such a swap isn?t feasible either, for in addition to the aforementioned four-pot and V6, GM?s engine catalogue also features a direct-injected variant of the VE Commodore?s LY7 3.6-litre V6.

More power, more torque and lower fuel consumption are there for the taking, all Holden needs is to embrace direct injection with the same vigour as its American cousins.
