Despite the X1 getting the new TwinTurbo four-cylinder engine, the U.S. market is rumored to initially receive the X1 xDrive35i. The high-end X1 is equipped with the N55 turbo six-cylinder engine which produces 300 horsepower.
Last week, BMW made the headlines of many automotive publications with the announcement of their new four-cylinder TwinPower 2.0 liter engine. Dubbed N20, the engine will be first used in the new X1 xDrive28i and produces 245 horsepower and 350 Nm of torque (258 lb of torque).
The engine can be matted to a 6-speed manual transmission or a 8-speed automatic transmission.
In the EU test cycle, the BMW X1 xDrive28i runs with 7.9 liters/100 km or 35.7 mpg imp (an improvement of 1.5 liters / 5.7 mpg), has CO2 emissions of 183 g/km (down by 38g).
Closely modelled on the BMW in-line six-cylinder engines, the all-new 2.0-litre engine with all-aluminium crankcase comes with BMW TwinPower Turbo technology features high-performance twin-scroll turbocharging system, High Precision Injection direct petrol injection with innovative solenoid injectors, and the latest further enhanced version of the BMW-patented VALVETRONIC variable valve control system.
Car and Driver reports that the BMW X1 xDrive28i with the new engine will make its debut in Europe only and no news around an U.S. debut are available at this time.
Their sources mention that eventually the turbo four should replace the naturally aspirated 3.0-liter six in all BMW products. Car and Driver was told the 2012 Z4 will be one of the first recipients on our shores, followed by the new 3-series and 1-series. Once those models arrive, and assuming the M3 follows through with its move to a turbo six, BMW will have an all-turbocharged lineup.[Source: C&D]
