Diesel may cost more than regular gasoline (about $0.24 more per gallon, per AAAâs current figures) but itâs much richer in energy â between 25% and 30% richer. The new BMW 328d (d for diesel) gets better mileage than the gas-powered Smart fortwo coupe. And it produces 180 horsepower, compared to the Smartâs measly 70.
Speed is more critical on a diesel than a gas engine. On the highway, in the 50-75 mph range, the fuel economy will go down about 3 mpg for each 10 mph increase in speed. A gasoline engine will lose about 1-1/2 mpg for each 10 mph increase in speed.
