BMW X3 gets a turbo four-cylinder

The turbocharged four-cylinder engine in the 2013 BMW X3 is rated at 240 hp.




BMW is expanding the use of its N20 turbocharged four-cylinder engine by making it the base powerplant for the 2013 X3 SUV.
The X3 xDrive28 will use the twin-scroll turbocharged 2.0-liter engine that produces 240 hp and 260 lb-ft of torque. Twin-scroll turbocharging means that the exhaust stream of cylinders one and four follow a separate path to the turbine wheel from cylinders two and three. It reduces back pressure at low engine rpm, improving throttle response.
BMW says the xDrive28i will go from 0 to 60 mph in 6.5 seconds, on its way to an electronically governed top speed of 130 mph. Fuel-economy ratings haven't been released.
In addition to the new engine, BMW has upgraded the list of standard features on the X3. Basic equipment now includes auto start/stop, Driving Dynamics Control with Eco Pro, a power tailgate and 18-inch wheels.
The stop/start system improves fuel economy by 3 percent, BMW says. The system can be switched off with a button by the ignition.
Driving Dynamics with Eco Pro mode can be accessed through the center console. The system improves fuel economy by optimizing drivetrain, heating, air-conditioning and electrical functions by dialing those functions back. It also displays driving tips on the iDrive and fuel saved as bonus miles added to range.
The X3 reaches showrooms in May and is built at BMW's plant in Spartanburg, S.C. The xDrive28i will cost $37,995, while the xDrive35i will cost $43,595, including destination and handling.
