[QUOTE]I've been frequenting a VW TDi group to learn more about how to get the most out of my new turbodiesel work truck. Some of the VW TDi owners brag about getting 35 mpg in town under favorable conditions, which agrees with the EPA estimates. But our 2002 Prius gets an honest 45-50 mpg in town (our main driving location) in warm weather, and consistently over 40 mpg fully loaded on long 75 mph trips. At 65 mph with lighter loads it will turn in 50-60 mpg. Efficiency, absolutely. It is also the most fun of any car I've driven since I had to sell my beloved Lotus 30 years ago.[/QUOTE] You might also check out Fred's tdi page tdiclub.com - some of those guys are getting 65mpg with their TDi's, although prolly not at 75mph, and they have their motors 'tuned' a bit... FWIW, in decent weather, my '02 Accord has gotten 40mpg on long 75mph trips while using A/C, but it is a 4cyl./5-spd.
