The new BMW 1 Series Coupé features rear-wheel-drive dynamics and seating for four (2+2). The BMW 135i is powered by BMW's twin-turbocharged 3.0-liter inline six-cylinder engine, which produces 300 horsepower and direct piezo gasoline injectors, twin low-mass turbochargers and air-to-air intercooling. The car accelerates from 0-62 mph in 5.3 seconds. The engine features on-demand engine coolant pumps that improve fuel economy. Starting in the spring of 2008 in the U.S., the 1 Series Coupe will be available in two versions; the 128i and the 135i, with an M Aerodynamic Kit.
