Since its introduction in the early 60’s, the Ford Mustang has experienced periods of highs and periods of lows. The good thing about the Mustang is that Ford has never taken its eyes off this iconic car. It is a testament to good old-fashioned engineering backed by powerful engine muscle. There have been many variations of the Ford Mustang during the years, and we’ll have a look at a few that seemed more special than the others. Some of these cars are limited-edition (less than 5,000 units) and some have large production numbers (more than 100,000) but they have one thing in common. They are the among the best muscle cars in the world.

New cylinder head design combines key parts into single aluminum casting

PONTIAC, Mich. – 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. Read more!
