Alpina XD3 Biturbo

Alpina has presented its own take on the BMW X3 today at the kickoff of the 2013 Geneva Motor Show. At its heart is a straight-six, full-aluminum 3.0-liter engine with two turbochargers, common-rail direct injection and variable turbine geometry. It has a maximum output of 350 HP (257 kW) at 4,000 rpm and a peak torque of 700 Nm (516 lb-ft) reached between 1,500 and 3,000 rpm.
Despite the powerful engine, the Alpina XD3 Biturbo manages to have a fuel consumption of only 6.8 liters / 100 km (41.5 mpg US or 34.5 mpg UK) while CO2 emissions stand at 180 g/km. This was possible thanks to the ZF eight-speed automatic transmission designed specifically for this model.
Other highlights of this heavily modified X3 include electronically-adjustable dampers, 20-inch Alpina Classic wheels with Michelin Pilot Super Sport low-profile tires, custom exhaust manifold, stainless steel exhaust system with dual double-ended tailpipes, along with several interior enhancements such as a sport steering wheel with blue/green stitching, door sills, floor mats, gear indicator and a digital speed read-out.
