BMW introduces diesel 2015 X3 before Chicago Auto Show

BMW's successful X3 SUV is getting new features for 2015, the company said on Wednesday before the Chicago Auto Show. For the first time in the U.S., a diesel engine will be offered on the midsized 'ute, as will a lower-cost rear-wheel drive model.

The BMW X3 xDrive28d -- quite a mouthful -- will deliver 180 hp and a robust 280 lb-ft of torque using a 2.0-liter, TwinPower turbo diesel engine. Power is transferred through an eight-speed automatic transmission. BMW says this version can get to 60 mph in less than 8 seconds.

Other engine options include the company's excellent 3.0-liter turbocharged I6 making 300 hp and its 2.0-liter turbocharged I4 making 240 hp and 260 lb-ft of torque. “xDrive” branded cars will feature all-wheel drive, "sDrive” signifies rear-wheel drive.

For efficiency, eco pro mode activates a coasting function that disengages the powertrain at speeds from 30-100 mph when the driver takes his foot off of the accelerator.

The 2015 X3 is nearly identical in size to the outgoing model. It features redesigned twin-circular headlights or full LEDs, a bigger grille and new front and rear bumpers. Its LED turn signals move to the exterior mirrors.

Two main trim packages will dominate the X3 landscape: xLine and M Sport. The first features metal inserts in the bumpers, satin aluminum side cladding and bars in the intakes, and simulated under guards. The M Sport gets M aerodynamic parts, high-gloss trim, sport seats and an Anthracite roof liner. It will also come with a sportier transmission setting and upgraded steering and suspension.

BMW's iDrive system comes standard on the X3, as does the Ford-like Smart Opener system that opens the hatch with a wave of the foot. The rear storage area can be configured to accommodate multiple types of cargo.

The rear-drive X3 sDrive28i starts at $39,325, the xDrive28i costs $40,725 and the xDrive35i goes for $45,825. The diesel xDrive28d starts at $42,825. The 2015 X3 goes on sale this spring.
