BMW’s Diesel Surprise

With the 2009 BMW 335d Sedan, it might seem the German automaker is taking a big risk with its reputation as the originator of the sports sedan by plopping a diesel engine under the hood.

Happily that is not the case.

The 335d is free from the three “Ss” that cloud Americans’ view of diesel cars: smoky, stinky and slow. New technology has vanquished the first two; turbo charging eliminates the last.

The 335d is BMW's first clean diesel passenger car for the North American market.

Driving the 335d on the infield road course at AAA Speedway erased any doubts. Despite burning a different fuel, this car possesses all the traits of a gasoline-powered 3-Series. Rapid acceleration, crisp handling and sure-footed braking are in abundance. Pitched into a corner, the car takes a set and drifts just enough to get around the apex quickly, thanks to the optional Sport Package ($2,150). Gear shifts are quick and smooth with the Steptronic automatic transmission, which is good because the 335d doesn’t come with a manual gearbox.

Good manners on the track are only part of the diesel Bimmer’s street cred. A bevy of standard features include advanced safety features, Xenon headlights, heated mirrors, rain-sensing wipers and heated windshield washer jets. The AM/FM CD/MP3 audio system has an auxiliary input for music players, but the iPod and USB adapter will set you back $400—a bit steep in our view.

Diesel power’s big advantage over gasoline is fuel economy. If you spend a lot of time driving on the highway, the EPA-estimated 36 MPG will be more than welcome. City driving rates a respectable 23 MPG. The 335i notches 17 city and 26 highway.

Suggested retail starts at $44,725, including $825 destination charge. The 335d qualifies for an IRS tax credit of $900.
