We already know that the 2012 Chevrolet Camaro V6 models make more power – rated at 323-hp (an increase of 11 over the 2011 engine) while makes no compromise to fuel-economy. How does it do that?

Here’s what GM says:

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.

“Reducing engine mass of this magnitude doesn’t happen often,” said Ameer Haider, GM assistant chief engineer for V6 engines. “Engineering usually looks for reduction in terms of grams not pounds. It’s just like removing a set of golf clubs from your car when you don’t need them – ultimately it saves fuel. When combined with other mass reductions, the customer will see better fuel economy over time with better performance.”

“The new, patented design benefits the customer in all the key areas without any tradeoffs, said Haider. “Emissions, performance, fuel economy, and noise all improve with the integrated exhaust manifold.”
