Do Clean Diesel vehicles have the same problems that gave diesel a bad name, such as smoky exhaust, engine knock or trouble starting in the cold?
No. Today’s modern diesel engines no longer smoke and have no trouble starting in cold weather. In fact, thanks to the amount of torque available and diesel vehicles’ reputation for long-term dependability, more and more people prefer Clean Diesels such at the Jetta TDI (named 2009 Green Car of the Year) to gasoline-powered vehicles.
