Official: BMW 2.0-liter Turbo Coming to the USA in 2011, Replaces 3.0-liter Straight-Six


We knew BMW's brand-new 2.0-liter turbocharged four-cylinder engine was coming to the States but now, the Bavarian automaker has made it official. The German company released a statement saying the first cars to be equipped with the force-fed four-banger will "arrive later this year" in the USA. The 2.0-liter unit made its debut on the X1 compact crossover and will eventually replace BMW’s trademark normally aspirated 3.0-liter inline six. While BMW's US division has yet to announce which models will get the new engine, in Europe, the automaker has already confirmed the powerplant for the Z4 coupe-roadster and the 5-Series range.


In the U.S., the naturally aspirated 3.0-liter inline-six is currently available on these models:
-128i Coupe / Convertible 230HP
-328i Sedan / Coupe / Convertible / Sports Wagon / xDrive 230HP
-528i Sedan 240HP
-X3 xDrive28i 240HP
-Z4 sDrive30i 255HP
There's a strong possibility that BMW will offer the new 2.0-liter turbo on all of these models in the U.S. but this has yet to be confirmed.

BMW's more for less 2.0-liter unit combines twin-scroll turbocharging with high-pressure direct-injection and the firm's VALVETRONIC intake control. In the X1, the maximum output of 240 horsepower is achieved at 5,000 rpm, or 1,500 rpm lower than in the normally-aspirated 3.0-liter inline six. The peak torque of 260 lb-ft, comes on tap at just 1,250 rpm, which according to BMW, is not only 30% more torque than the aforementioned inline six, it also peaks 1,500 rpm earlier. On top of that, BMW says the four-pot also returns 16 per cent better fuel consumption and lower CO2 emissions.
