The BMW X5 3.0d uses an engine with high-precision piezo crystal injection technology for better economy and emission figures. This advanced technology, combined with the introduction of an all aluminium crankcase that saves 25kg in weight compared to the former 3.0-litre diesel engine, sees the new X5 record improved performance figures. It is now seven per cent more fuel efficient with a combined fuel consumption figure of 32.5mpg while also emitting eight per cent less CO2. The 3.0d engine records 231g/km.
While the new X5 is more economical it still comes with increased power. Output from the 3.0d engine is 231hp, up six per cent compared to the previous model, and maximum torque is 520Nm, up four per cent. This peak torque is available from 2,000 to 2,750rpm offering near instantaneous reactions for swift yet refined motoring. Such an advanced engine powers the BMW X5 3.0d from zero to 62mph in 8.3 seconds before going on to a top speed of 134mph (130mph for a non-Dynamic Package equipped model).
Based on the world’s lightest production six-cylinder petrol engine, the BMW X5 3.0si comes equipped with BMW’s patented Double VANOS and VALVETRONIC variable valve technologies for high performance, yet economical, motoring. Put simply, Double VANOS determines when the engine’s valves open, while VALVETRONIC determines by how much. The net effect of both systems is that the engine is always operating at its optimum efficiency with only the exact amount of fuel needed being used. This is why the X5 3.0si has a combined fuel consumption of 25.9mpg (an 18 per cent improvement compared to the previous X5 3.0i) and an emissions figure of 260g/km, but still delivers maximum driver enjoyment.
Developing 272hp at 6,650rpm, the high-revving nature of the engine and its sonorous exhaust note set it apart from the competition. Peak torque of 315Nm is attained at 2,750rpm for in-gear responsiveness, with zero to 62mph dispatched in 8.1 seconds. Top speed for the new BMW X5 3.0si is140mph (when fitted with the Dynamic Package).
Representing the flagship of the range, the BMW X5 4.8i with its 355hp engine is faster from zero to 62mph and has a higher top speed than the supercharged Range Rover Sport or a Mercedes Benz ML500 Sport. The 4,799cc V8 powers the car to 62mph in just 6.5 seconds before going on to a top speed of 150mph (when fitted with the Dynamic Package). Despite such scintillating performance, fuel consumption is a respectable 22.6mpg on the combined cycle and emissions are 299g/km.
