Diesels are very popular these days. They perform well, with stump-pulling torque, and are vastly more efficient than their gasoline-powered counterparts. Whereas a few decades ago a diesel engine would be written off as a smokey, slow oil-burners, these days the demand is very high, and former negative diesel traits have all been eliminated due to the advanced technology of today.
Perhaps the most impressive diesel offerings come from the German manufacturers. BMW , Audi , and Mercedes all offer several diesel engines that are every bit as desirable — if not more — as their respective gasoline versions.
Audi has an innovative new spin on the turbo-diesel with itsA6 . It is still a mono-turbo setup, but with an electric turbo chiming in to help out at lower revs. This innovative design will virtually eliminate turbo lag and provide even more oomph off the line than diesels are already famous for.
