The new X5 inherits the latest 2933cc aluminium six-cylinder turbodiesel already in service in the 3-series. This engine not only produces more power and torque than the previous 3.0d but is also cleaner and leaner. All new X5s get a revised six-speed automatic gearbox as standard. With a secondary damper unit, the torque converter operates with less slip to increase efficiency and shift speed with no detrimental effect on refinement.
Our test X5 comes equipped with the 3.0-litre diesel engine that will account for the majority of UK sales; the diesel took 93 per cent of the previous model’s volume, and that’s unlikely to change this time. The rest of the range is made up of two petrol engines: a 3.0-litre six and a 4.8 V8. They’ll all be automatic, too; there’s no longer a manual X5 option.
At 232bhp, the X5’s diesel engine is one of the more powerful in its class, and it gives this 2225kg SUV a healthy turn of speed. We recorded a 0-60mph time of 7.9sec (Audi’s Q7 takes 8.6sec and the Range Rover Sport TDV6 needs 11.9sec), and there’s a broad spread of power throughout the 3.0d’s rev range. Peak torque of 383lb ft is developed at 2000rpm, so response from low revs is excellent too. The X5’s brakes (ventilated discs all round) give good stopping power, while pedal feel is pretty good too.
The six-speed automatic gearbox shifts for the most part smoothly and quickly, but can prove slightly indecisive on occasion if you’re pressing on.
There’s also the option of shifting yourself via the X5’s new electronic shift lever. Though this takes up less space on the centre console and needs less effort to move, it’s fiddlier than a standard lever to use, and it’s all too easy to knock the X5 into neutral if you drive with your hand resting on it. BMW claims it gives an ergonomic advantage, but we’re not yet convinced.
