Toyota makes the best cars. I think their hybrids are fantastic. If they had a diesel hybrid you’d get 100 miles per gallon and the electric phase would also contribute to the power.
A few years ago Mercedes displayed a diesel hybrid at the NY Auto Show (which I always make it a point to attend).On the door was "4.1L/100KM"...meaning just over a gallon used every 62 miles.It was expressed that way because the car was only scheduled for sale in Europe.It's my understanding that there are at least several diesel hybrids available today in Europe.
