With gas prices so high, the mpg is very important to me. My '89 F-150 with 5.0 liter V-8 only gets about 16. My father's Golf TDI gets >40 with a torkey and sporty 1.9 litre 110 hp Diesel engine. I wish, Ford would develop an engine rivallign the Tuareg's V-10 Diesel... Here in Thailand, about 85% of all cars and trucks are Diesel powered.
