Efficiency combined with performance is what BMW promises to offer U.S. consumers with the new 335d and the awkwardly named X5 xDrive35d. Both vehicles are fitted with a twin-turbo 3.0-liter inline-6 diesel engine that generates a healthy 265HP and an even more impressive 425 pound-feet of torque at just 1,750 rpm – for comparison, the Corvette Z06’s LS3 V8 makes 423 lb-ft. BMW claims that the 335d goes from naught to 60mph in 6.0 seconds while delivering 36mpg on the highway. The heavier X5 diesel hits the 60mph mark in 6.8 seconds and offers an average fuel economy on the highway of 26mpg.

Prices for the U.S. market have been set at $44,725 (including destination and handling) for the 335d sedan and at $52,025 (including fees) for the X5 xDrive35d. BMW supports that both diesel models are eligible for the IRS Alternative Motor Vehicle Credit meaning that buyers will qualify for a maximum tax credit of $900 for the 335d sedan and $1,550 for the X5 xDrive35d.

“This is an important launch for BMW,” said Jim O’Donnell, President of BMW of North America, LLC. “Both of these vehicles have outstanding fuel efficiency while offering performance that delivers on the promise of the Ultimate Driving Machine. With up to nearly 600 miles of range, these BMW Advanced Diesels will be perfect for the way Americans drive.”

The production versions of the BMW 335d Sedan and X5 xDrive35d will make their North American debut next week at the Los Angeles International Auto Show.
