2011 BMW 528i: A Word About Its Fuel Efficiency

December 14, 2010

lf you're willing to spend this much money on a luxury sedan, you're probably not living paycheck to paycheck. Or maybe you are, which would make you stupid, but that's another subject.

We'll assume that the majority of 5 Series buyers have sufficient means to spend on what they want. So why buy the "small" engine in such a big sedan?

Most will assume it's to save money on the initial purchase, but some people might actually buy it to save gas over the long haul. And that's not a totally ridiculous idea. So far, our 528i has averaged 24.5 miles per gallon in its first 6,000 miles or so.

Not a huge number, but we've been wringing it out pretty hard to get a feel for the engine and its new eight-speed transmission. On some of the more highway-heavy tanks, we recorded as much as 31 mpg, which is right around its EPA rating.

Along the way, few have complained about a lack of power. It's not fast by any means, but it's not slow either. If you were at all interested in getting decent mileage, there would be little reason to complain about the overall performance of the "small" engine.
