Top 10 Cars We’re Tired Of Waiting For

10. Mazda6 Diesel

The Mazad6 was supposed to be available in the U.S. with a diesel engine by now, but the company continues to delay delivering an oil burner here. We even had the chance to drive a prototype version of the new engine in the last generation vehicle back in 2011. The engine exists in other markets and we know it’s a solid performer, so what’s stopping it from coming?

Mazda says can’t meet emissions standards in North America without sacrificing performance. The Japanese automaker doesn’t want a costly urea treatment system, and other options aren’t up to snuff with the brands idea of how the engine should perform.
