A trip to slippery Sussex proves the worth of our saloon’s all-wheel drive system
Allan Muir
14 March 2017

A run from London to West Sussex and back via lanes liberally sprinkled with leaves, mud and other low-friction substances provided a timely reminder that there are more benefits to having four-wheel drive on a car like the 3 Series than just extra traction under acceleration.

Our 320d xDrive felt rock-solid and surefooted, but whether it was more rock-solid and surefooted than a rear-drive 320d would have been is hard to say without a back-to-back comparison. It certainly inspired confidence, which can only be good. The 320d’s xDrive system divides drive 40/60% front to rear under normal conditions but can send 100% of drive to either axle if needed.

Hard acceleration on a slippery surface is interesting; there’s a tiny bit of slip (unlike that of my Land Rover Discovery Sport, for example) before drive is shuffled around and full traction is found, and the driver can feel what’s going on through the steering, just a little. The steering is slightly sticky at times, but that could be to do with the way the electric assistance is calibrated rather than the fact that the car is all-wheel drive.

The BMW may have the traction of an all-paw SUV, but it doesn’t have their ability to soak up potholes. In Sussex, the 320d – on 19in alloys and low-profile tyres – slammed into two unseen craters with a level of violence that I haven’t experienced with the Discovery Sport. No obvious damage was done to alloys or tyres, but the impacts were painful enough that we’ll keep an eye on them.

Clearly there are more suitable cars for coping with British roads than a low-slung, big-wheeled saloon, four-wheel-drive or not.

This review is so vague and provides so litttle information about this BMW. And this is the standard now for automotive journalism a mere hint of what the car may be like .... "but whether it was more rock-solid and surefooted than a rear-drive 320d would have been is hard to say without a back-to-back comparison." but never will there be so much as a comparison with the other BMW mentioned. Instead you keep us in the dark. Silly.

Yu autocribblers annoy me. You prattle on as if everyone was born with the intention of going hell for leather on two wheels round corners and lurid slides mimiking drifters round a round-about!! Get real please. 99.9% of readers here do not even try to do it. So can we please have serious tests and reporting. Meanwhile of course 4wd is always going to be more safe. Sad about the pollution of all diesels. They should be forced to stop production NOW not when our children are dying

Pitifully inept article; March 14, 'Winter almost here'? I won't be back, you've lost another reader.

This got my goat too. The article was staggeringly vague, not to mention the references to a Discovery Sport that isn't in any way a natural car to compare this with. More often than not, Autocar, readers are left wondering if your Editor does any actual editing. You know, reading journalists' output with a critical eye as to content, language, grammar and general sense.

It does make you wonder how 'normal' people drive their 'normal' cars manage to drive anywhere ! I have no doubt that 4 wheel drive can be a boon in snow and ice, but most drivers take account of the conditions and do not need to buy something like this.

Reads like it has been plagiarised from a local rag that was printed in November.

I have never heard anyone, especially a car journalist, compare an SUV with a saloon before! Totally pointless comparisons...

Filler…nothing more. Amateur hour is back again...

This is not good journalism. I live in Norway, and drive for half of the year on low friction surfaces in a front wheel drive low slung car, as does most of the rest of the population of the Nordic countries. We do it with winter tyres, not 4 wheel drives (some exceptions, granted). If Autocar would have the balls to do a winter tyre test, most people would realise that its much safer, much cheaper, and much more effective to spend £400 on winter tyres, than optioning £1500 of 4 wheel drive. But the car manufacturers wouldn't like that would they.... ....oh no.....

    The Citroen C3 Aircross has got funky looks and a charming interior, but it's another small SUV, and another dynamic miss. Numb steering is just one thing keeping it from class best

    Diesel version of Skoda’s junior SUV is unobtrusive and undemanding, but we’d still go for the silkier petrol version of the Karoq

    Is the third gen Citroën C3 ‘fresh and different’ enough to take on its supermini rivals? We spend six months with one to find out

    A satisfying rework of the X3 that usefully improves its handling, cabin finish, space and connectivity to make this BMW a class front-runner again
