The 2009 Volkswagen Jetta TDI is coming to VW dealers this summer as the first of the new batch of 50 state clean diesels and the official EPA fuel economy numbers are now out. The diesel has come in with ratings of 30mpg on the urban cycle and 41mpg on the highway cycle. Those numbers are a bit lower than expected, with Volkswagen having implied previously implied that 40mpg both city and highway were possible. More recently they have indicated that real world highway figures of up to 60mpg were possible.

Regardless of the expectations we might have had, these numbers are a huge improvement over the current 2.5L five cylinder and 2.0L turbo offerings. The 34mpg combined figure is a 41.7 percent improvement over the 2.5L and 36 percent boost over the 2.0L. The Prius is rated at 48/45mpg city/highway. We'll be looking forward to our chance to evaluate a new Jetta TDI to see how it does in the real world.

Update: We just talked to VW spokesman Keith Price about the EPA numbers and his response was that the VW TDIs typically do better in real world mileage performance than the official ratings. We'll reserve judgement until we get our hands on one in late June.
