How entirely fitting it was that the day of this test was that day that always comes each autumn.
You know the one. It’s Monday morning. You leave the house in darkness. It is pelting with rain. You know that you’ll not return before darkness. There is no question about it: you will need a decent coat, from this very day forward, until the return of spring.
The only question is what car should accompany you from this day forth, too. A car for squalid, wet road conditions during which, when the asphalt isn’t merely covered in rainwater, it’s covered in mud, frost, wet leaves, snow, ice or gritted slush.
Conventional wisdom and shrewd advertising suggest that you want four-wheel drive. However, do you need it and, if so, how large a vehicle do you want with it? A full-blown 4x4? A rapid estate? A sports car, supercar or conventional hatchback? Is either front-wheel drive or rear-wheel drive completely out of its depth?
To answer all of these questions and more, we gathered together the cars that you see here. Five are four-wheel-drive, and each a different kind of vehicle: our SUV is a Range Rover Sport with a supercharged engine; the sporting GT car is a Porsche 911 Carrera 4S; the hatchback is a fast one, a Volkswagen Golf R; the family estate another fast one, an Audi RS4; the archetypal all-weather supercar is Nissan’s GT-R.
In the front-driven corner, we have a fairly regular hatchback in the shape of a Mini Cooper, and representing rear-wheel drive cars is a Toyota GT86. Both are light and wear sensible rubber.
We’ve left it to the discretion of those who supplied the cars as to which OEM tyres their cars arrived wearing.
At 13deg ambient temperature, theoretically it was too warm for winter tyres to enter their optimum zone, but some winter tyres can disperse more water than their ‘summer’ counterparts.
As it is, the Range Rover’s Continental Crosscontacts are winter-proof anyway, and all of the other cars came on conventional rubber bar the 911, which arrived wearing Pirelli Sottozero winters.
To complete the equation, we enlisted MIRA proving ground’s wet handling circuit and wet straights, on which we ran five different tests. Our Vbox supplied the data. Our spreadsheet did the mathematics. By the end, we will know in a fairly scientific fashion which car is, beyond doubt, the best in the wet.
Test 1: 70-0mph
Fairly straightforward test, this. You’re travelling on a motorway at the legal limit when somebody swings into a lane in front of you and loses control. You have to stop. Now.
Here, four-wheel drive is, of course, no use whatsoever, because none of the wheels is driving. What helps are good tyres, little weight and sound weight distribution. Which is why the Mini Cooper steals a very early advantage, stopping in just 55.2m.
It’s a good result that is almost matched by most of the other cars here. Toyota’s GT86 is one exception. Despite being light and on generous rubber (215/45 R17) it needs 60.1m.
The other exception is the Nissan GT-R, whose 255/40 ZR20 front and 285/35 ZR20 Dunlop Sport Maxx tyres simply won’t bite initially. There’s also its notable 1740kg kerb weight. So even though it slows from lower speed with lots of conviction, it takes a long time to get going. Ditto the Range Rover Sport, whose tyres do what they can but cannot alter the fact that it weighs over two tonnes.
