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.
A gallon of ethanol contains less energy than a gallon of gasoline. The result is lower fuel economy than a gallon of gasoline. The amount of energy difference varies depending on the blend. For example, E85 has about 27% less energy per gallon than gasoline (mileage penalty lessens as ethanol content decreases).
