For reasons too boring to explain, I did a lap of the M25 on Monday, every mile of which took place in rain of biblical proportions. In that time I saw six single car accidents. One was a knackered old Cavalier and another an even older Mazda MX-5. But the remaining four, from a Range Rover to a Porsche 911 were all in their youth and had one other thing in common: four-wheel drive.

Crash Coincidence? I think not. I was driving a modern rear-wheel drive car and after a few flashes of the traction control light, I was left under no illusions as to the available grip levels. If I’d had four-wheel drive, I doubt I’d have had a clue. That’s one problem. The second is the morons who so often drive all-wheel-drive cars, convinced an extra pair of drive shafts somehow grants them immunity from nature. The third are car manufacturers who implicitly or otherwise market all-wheel drive as a safety system. It is not.

Before my M25 experience I asked a senior Volvo engineer what, as a representative of perhaps the most safety oriented car brand, he thought of four-wheel drive as a safety feature. His reply was interesting, particularly as Volvo sells cars both with and without four-wheel drive:AU_1870_l
