The 2012 Chevrolet Camaro will feature 323 horsepower, or 11 more ponies than the 2011 model. Engineers were able to add extra power by allowing the high-tech mill to breathe better. To do this, intake airflow was improved by seven percent through extensive simulation and bench testing. As a result, power is up by 11 horsepower, while exhaust flow is improved by 10 percent. Engineers also manged to remove an incredible 13 pounds from the 3.6-liter by integrating the exhaust manifolds into the aluminum cylinder head. This change meant that a pair of old-school iron manifolds, 12 bolts, a pair of gasket and heat shields with six more bolts were eliminated.
