Ford’s TwinForce.. err, sorry, EcoBoost motors have really gotten the attention of the automotive world lately, but GM is not to be outdone in the powertrain department. GM plans to fit a turbocharged version of it’s 1.4 liter four-cylinder in future iterations of the Chevrolet Cobalt and Saturn Astra.
The 1.4 liter motor already exists in non-turbo form in the European Opel Astra. If sucessful in small cars, these engine could see duty in mid-sized cars as well. Jim Queen, GM’s Chief Engineer, optimistically added, “You’re going to see turbocharged four-cylinders in vehicles that no one could have ever imagined that they would be in.” Oh the possibilities.
Turbocharged direct injection motors have provided automakers with a cost-effective method to improve mileage in wake of increased CAFE standards, without sacrificing our thirst for well-motivated machines.
With Ford expecting half a million EcoBoost-powered cars on the road by 2012 and GM ready to start seeking out more widespread use of its upcoming 1.4 turbo four-cylinder, the saying, ‘no replacement for displacement’ has become all but irrelevant.
