Diesel is proven technology. With the introduction of ULSD in 2007 now the US can fuel the advanced clean diesels that are already made in Europe. Diesels get 30% better mileage than the same internal combustion engine and last longer. The uplift for diesel is less than the uplift for hybrid drive train. No battery replacement issues. Diesels will kick hybrids ass.
