The age of the diesel supercar has dawned. Ferrari should worry.

Diesel rush begins: VW Jetta TDI Officialy Out

Lovers of both fuel mileage and torque can finally rest easy, Volkswagen of America is now officially selling its 50-State-approved, clean diesel engine in either the Jetta sedan for $21,990 or Jetta SportWagen wrappers for $23,590. Equipped with the six-speed DSG transmission, both Jetta gets an EPA rating of 29 miles per gallon in the city and 40 on the highway. We expect to see better real-world numbers, though we're a bit wary of VW's advertising its alternate rating of 38/44 -- a number that is impossible to compare with anything else currently available. In any case, the $2,000 premium for the TDI engine will be lessened somewhat by the Fed's $1,300 tax credit which applies to either TDI model. Look for an early test of the oil-burner on these pages shortly.
