The BWM 5 xDrive30d is a 4×4 crossover SUV with all the performance of a sports saloon whist delivering a very impressive fuel economy and relatively low CO2 emissions. Certainly the car has a very upmarket image, it is very robust with a superb quality of build, and a firm ride.

On the downside, although it does perform reasonably well off-road, by no means can the car be considered a true off-roader, though for occasional off-road it is fine and with the potential of adding additional seats it can easily transport seven occupants on the daily school run.

Taking the whole of the BMW 5 series there are a number of engine options but by far the most popular are the diesel powered models which account for over 90% of sales. There are two of these which deliver 235 bhp and 386 bhp. There are also a 272 bhp 3 litre and a 355 bhp V8 4.8 litre petrol engines available.

The BMW 6 xDrive35d was launched in 2008. This model moved on a little from the 30d and is less bulky and a little lighter. It also handles better than the previous model and of the two Motors it generally has a higher level of performance. Out of the total BMW 6 range the 35d is the most popular. In fact this uses a very similar engine to 30d but the latter has a single turbo charger whilst the former has twin turbochargers and produces 286 bhp.

Bothe the BMW 5 30d and the BMW 6 35d are luxurious cars with very high levels of comfort. The driving experience is excellent and there is good all-round visibility.

In 2010 BMW added the X3 xDrive30d and the X3 xDrive35d to the BMW 3 series range. Both have 8 speed automatic gearboxes and several additional features including 18 inch alloy wheels. Maximum power output is makes 313 bhp and the 0 to 62 mph acceleration time is 5.8 seconds.
