Prius vs TDI fuel economy


The most recent Autoweek article rates the VW Jetta TDI with higher fuel economy than the Prius. There are plenty of articles that show the opposite... the Prius gets higher fuel economy than the TDI, especially in town/city driving.

This guy on livejournal posted the results of a real-world test in Canada involving some cars we're all familiar with. As with CR's results, in a real-world test, the small diesel car didn't even come close to the mileage of the bigger (midsize) Prius.

Mileage on the Highway
All four cars got more than 40 mpg, and the Prius hit 50. Amazingly, the One-Calorie Toyota Echo squeaked above its EPA highway number (39) to 41 mpg. The diesel, at 42 mpg, fell 2 mpg behind its EPA rating.

Mileage in Town
The Prius again scored at the top with 52 mpg. Dr. Diesel, in last place at 33, was a bit of a surprise. We expected more. Diesels are at their best, relatively speaking, under light loads; they inject very little fuel and they have no throttling losses. Again, the One-Calorie Echo did superbly at 42 mpg.
