Before you go tearing my head off, yes I know diesel engines have been in cars for many years and yes I do know that Mercedes has even had many diesel cars in the US. With the new clean diesel standards and the ultra-low sulfur diesel many more car makers are getting into the market.. or at least thinking about it. So what is the big deal with these cars? In my opinion, this is the beginning of the revolution of affordable diesel cars in the United States. Sure these cars are expensive luxury cars, but just wait till this Bluetec engine trickles down and finds its way into other DCX vehicles. Imagine a diesel Sebring, 300M, PT Cruiser, Jeep Wrangler. So until then, we can all just keep dreaming, wishing, and drooling over these sweet Benz's.
