For driving pleasure in two worlds: whichever engine you choose, efficiency and performance are the hallmarks of all three diesel and petrol engines in the BMW X5. The xDrive50i with a V8 engine impresses with its power and sophistication while the xDrive35i with a straight six-cylinder engine lets its efficiency speak for itself. And with BMW's EfficientDynamics technologies, performance isn't scarificed in the name of efficiency. The 2011 BMW X5 xDrive35i with a 3.0L inline six-cylinder engine accelerates from a standstill to 100 km/h in the same 6.8 seconds as the prior year's model with a 4.8L V8 engine (the 2010 BMW X5 xDrive48i). Sophisticated power and outstanding efficiency are the hallmarks of the BMW straight six-cylinder engine of the xDrive35d diesel engine. You don’t have to fly business class to be able to experience instant acceleration to top speeds with negligible interruption. The eight-speed automatic transmission with Steptronic in the BMW X5 not only ensures incredibly soft gear changes across all eight gears; it also significantly reduces fuel consumption. Exclusive, stylish - and unmistakably powerful: the M Sport Package accentuates the dynamic character of the BMW X5. Bumper and running boards in body colour as well as entry sills with the M logo are only the first in a long line of powerful and sporting impressions. Thanks to xDrive, the BMW X5 maintains perfect traction even on difficult road conditions. This intelligent system uses its Dynamic Stability Control sensors to detect the early signs of instability and reacts instantly as needed.
