The BMW tuning specialist has revealed a 350-horsepower twin-turbo X3 at the Geneva Motor Show.
Having revealed the B3 Biturbo at Geneva, Alpina also took the wraps off its BMW X3 program dubbed the XD3 Biturbo. Based on the xDrive35d, the XD3 Biturbo is powered by a full-aluminum 3.0-liter straight-six unit with two turbochargers, common-rail direct injection and variable turbine geometry, which produces 350 horsepower and 516 pound-feet of torque. The result is a 0-62 mph time of 4.9 seconds (just 0.2 slower than the X5 M) and a top speed of 158 mph.
Despite all that power, the Alpina XD3 returns fuel economy of 41.5 mpg thanks in part to the specially-made ZF eight-speed automatic transmission. Typical Alpina styling extends to a more dynamic front spoiler with integrated air intakes, a custom exhaust manifold, stainless-steel exhaust with dual double-ended elliptical tailpipes and 21" wheels. Interior enhancements include leather upholstery, sports seats, xenon headlights, a sports steering wheel, an Alpina instrument panel with digital speedometer and gear indicator, and Alpina door sills, floor mats and emblems in the seatbacks.
