2012 Chevy Camaro Gets More Power and Better Fuel Economy

The 2012 Chevy Camaro is a little “greener” thanks to some updates that give it more power, but at the same time saving more gas and putting out fewer emissions.

The 2012 Camaro 3.6L V6 gets a new integrated exhaust manifold cylinder head that replaces a cast iron exhaust manifold, six bolts, a gasket and a heat shield and three bolts. This change reduces the engine weight by 13 pounds, which has helped to improve the gas mileage of the Camaro. The Camaro 2LS model now gets 30 mpg on the 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.” 2012_chevy_camaro_exhaust_manifold3.jpg

The 3.6L V6 now puts out 11 more horsepower (323-hp) thanks to a new larger intake valves, which have improved intake airflow by seven percent. Exhaust flow is also 10 percent better than the V6 in the 2011 model.

“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.”
