Engineers were able to improve intake airflow through extensive simulation and bench testing. By getting more air into the engine, horsepower was increased along with exhaust flow. Additionally, engineers managed to shave 13 pounds from the overall weight of the engine, which ultimately helped improve fuel efficiency.
The 2012 Camaro 2LS model will now boast 30 miles per gallon on the highway, up from an also respectable 29 mpg from 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.”
