The Turbocharged Four-Cylinder Makes Its Triumphant Return

It's been almost 40 years since BMW released the 2002 Turbo, and until now, turbocharged four-cylinders from BMW have been nonexistent on U.S. shores – save the lone 1983 F1 race in Long Beach. That's set to change later this year when BMW brings its all-new turbo'd 2.0-liter to the States as its entry-level engine.

Despite the misleading name of TwinPower, this new four-pot is only packing one turbocharger (a twin scroll unit) and fitted with direct injection, double VANOS variable camshaft technology and VALVETRONIC variable valve control. The result is 245 horsepower (up 15 hp from the current 3.0-liter inline-six) and 258 pound-feet of torque (up from 200 lb-ft), available at an oh-so-low 1,250 rpm.

相信这几张图很多人会非常感兴趣的~

Combined with a choice of either a six-speed manual or the eight speed automatic pulled from the 5 series GT, a dual mass flywheel, electric water pump, a 14 mm offset crank, start-stop tech and an LDS coating that reduces weight and improves cooling, overall efficiency is up and fuel consumption and emissions are down. Fitted to the new X1 xDrive28i, the math adds up to 7.9 liters of fuel per 100 km, or just under 30 mpg on the U.S. cycle.

When is this new four-pot coming our way? BMW is set to announce the first U.S. vehicles to get the new turbocharged 2.0-liter at this month's New York Auto Show, but the smart money is on the 3 Series and X3, along with the entry-level 128i.
