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.
