New Car: 2011 BMW 740i/iL


Americans will finally see a rational application of BMW’s Euro-centric EfficientDynamics mantra when BMW unveils six-cylinder versions of its 7-series at the Detroit auto show in January. The 740i will occupy the lowest rung on the company’s executive-sedan ladder, below the plenty-powerful 750i, the extreme 760i, and the slightly ridiculous ActiveHybrid 7.

Power comes from BMW’s twin-turbo inline-six, which in this application makes 315 hp at 5800 rpm and 330 lb-ft of torque at a low 1600 rpm. Keeping track of BMW’s turbocharged sixes is becoming more complicated by the day; this represents a higher state of tune than the 300-hp twin-turbo version used in the 1-, 3-, and 5-series, which is separate from the high-output, 335-hp version recently announced for the Z4 sDrive35is, which is also different from the new single-turbo unit that also makes 300 hp and is debuting in the 5-series GT this spring. The engine will be backed by a six-speed automatic in the 7-series. The sixed 7 will look just like its V-8 siblings and will likewise be offered with a short (740i) or long (740Li) wheelbase as well with the full menu of packages and standalone options.

If we’re going to have to deal with downsized engines, at least the one sliding into the 7 is a sweetheart, and this car sure does make a lot more sense than the ActiveHybrid 7. Fuel economy hasn’t been disclosed, but we can safely expect mileage slightly better than the 15 mpg city/22 highway that the twin-turbo V-8 750i achieves, but not quite as good as the 535i’s 17/26 ratings. Let’s say maybe 16/24.

When the models launch in the spring of 2010 as 2011 models, it will have been 19 years since the U.S. was offered a six-cylinder 7. Mercedes hasn’t sold a six-cylinder S-class since the end of the car’s last generation, so, at least for now, the 7-series will own the six-cylinder (non-hybrid) luxury-sedan market.
