Head Games: 2012 Chevy Camaro Adds Power, Saves Fuel
New cylinder head design combines key parts into single aluminum casting
In auto production, more power, better fuel economy and fewer emissions rarely appear together. But the 2012 Camaro 3.6L direct injection V6 engine achieves all three by combining the exhaust manifold with the cylinder head into a single aluminum casting.
Each integrated exhaust manifold cylinder head – a V6 has two — replaces a cast iron exhaust manifold, six bolts, a gasket and a heat shield and three bolts. By eliminating this joint, the potential for a gasket failure is eliminated. And the change reduces engine weight by 13 lbs. or 6 kg per engine. Reducing mass helps improve fuel economy and the 2012 Camaro 2LS model is EPA estimated at 30 mpg highway. <Continued HERE for more info, photos, and video>
