BMW X3 Has A Turbo Four-Cylinder

BMW is extending the usage of its N20 turbocharged four-cylinder engine by creating it the base powerplant for the 2013 X3 SUV. The BMW X3 xDrive28 will apply the twin-scroll turbocharged 2.0-liter engine that generates 240 hp as well as 260 lb-ft of torque. Twin-scroll turbocharging indicates that the exhaust stream of cylinders one and four adhere to a separate route to the turbine wheel from cylinders two and three. It minimizes back pressure at low engine rpm, enhancing 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.

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 stop/start system improves fuel economy by 3 percent, BMW says. The system can be switched off with a button by the ignition.
