If I were to tell you that a BMW with a diesel engine can "beat" a Prius in fuel economy, would you believe me? No, I didn't think so, cause I would not believe it either. Two writers for the Sunday Times in London, have decided to see if the official fuel economy numbers released by the manufacturers will actually match in a real time scenario. The cars they decided to put head to head, were the BMW 520d with a 2.0-liter diesel engine and the hybrid Toyota Prius.
Fair game? Well, most of us wouldn't think so, but they still went ahead and scheduled a test to take place on a route from London to Geneva.
The BMW 520d got 41.9 mpg while the full-hybrid Prius, 500 pounds lighter, got 40.1 mpg, of course, U.K gallons(we were too lazy to do the conversion).
Here are some other interesting fragments from their report.
Whilst the BMW "doesn't have the external look of a green car and you don't get the same self-righteous glow when you are driving it," it does have a series of energy-saving features BMW calls EfficientDynamics: battery recharge when braking, good aerodynamics, low rolling resistance, a continuous fuel consumption gauge on the dashboard, and a six-speed manual transmission that is rated as improving fuel economy by about 10%. Testers found the 520d "not startlingly quick … [but] it cruised happily at the French autoroute limit (dry conditions) of 78mph towards the champagne region." When the trip was done, the BMW still had a third of its tank in reserve.
Now, we can we all say to BMW: what are you waiting for?? Bring us the diesel engines already.
