BMW X5 2004 review: first drive

The latter is familiar as it's been around for a few years and is used in umpteen BMW models.

The diesel only recently came to light in the upgraded X5 all wheel drive.

It replaces a similar engine in the earlier X5 but is a significant step up in performance, economy and operating characteristics.

This second generation diesel is surprisingly powerful at 150kW but even more impressive is the amount of torque it generates – 480Nm at 2000rpm.

That's more torque than BMW's the 4.4-litre, petrol V8 engine.

It drives through a six speed manual or optional six speed automatic (tested-$84,000) that gives strong, seamless acceleration at will and uses less than 10.0 litres/100km in the process.

There really is no down side to this excellent engine apart from the inconvenience of filling the tank at sometimes grubby and smelly diesel bowsers.

In addition to the new diesel engine, the X5 came in for a styling massage inside and out and also gained a new all wheel drive system called xDrive that is more effective off road and for general driving.

Specification levels across the range have also been increased but an extensive options list remains. As usual, a number of electronic systems modulate traction and drive.

Safety is well addressed with 10 air bags, ABS and a five star NCAP rating.

The six speed auto almost perfectly matches the engine's output but has an annoying deceleration trait at slow speed with perceptible down changes.

A sequential change mechanism is provided but is superfluous because of the performance available in normal D mode.

Despite its hefty weight, the vehicle handles well – better than most SUVs, and gives a comfortable, firm ride. Mind you, there are limits but the drive experience will please most drivers.

The X5 is equally amenable around town or on a trip and surprisingly proficient off road.

Virtually no noise or vibration intrudes into the cabin.

The luxurious interior has seats for five with a large load space in the back.The spare is a space-saver.

Standard equipment is extensive and the audio system is excellent. But fuel economy is the real surprise with at least 1000km available on one tank, more if you are careful. And with this comes performance at least on par with the petrol 3.0-litre and close to the V8. Can't argue with that.
