Yahoo Autos How a Device Ford Patented in 1999 Is Saving V8s
The naturally aspirated V8 is a dying breed. With every new iteration of a performance car, it seems we lose the N/A V8 to a smaller displacement engine with turbochargers attached to it. The sad thing is, the N/A V8 is one of our favorite engines. They all have a distinct character, oh, and they all sound pretty damn cool.
Thankfully, there are some N/A V8s that are still on the market, but that number is getting smaller and smaller everyday. American muscle cars are all on the list and have maintained V8s even in the face of increasing emissions controls and regulations. While the Challenger seems to eschew any and all compromises to emission controls, the Camaro's V8 features cylinder deactivation to improve fuel economy. And the Mustang? Well, in 1999, Ford developed something called the Charge Motion Control Valve. The system is able to make the engine very fuel efficient at low RPM and in situations where you're not hard on the throttle, but then doesn't get in the way when you want to go flat out.
