Test 3: 30-0mph on a mixed surface
This split braking test is like the acceleration one, only you stop rather than go. Simples.
Tyres and brake sizes and weight affect the result here, but because speeds are low, it’s just as much about the cleverness of the electronics. Anti-lock, electronic brake-force distribution and stability control all play a part. The driver might have to wind on a little lock here and there, but largely he’s a passenger.
Pleasingly, the results are all satisfactory. The quickest stopping time is 3.28sec, for the 911 again, presumably because of the water dissipation allowed by its winter tyres, and the slowest time is the Range Rover’s, presumably on account of its mass, at 3.93sec. The gap between second (impressive Golf R) and sixth (GT86) is only 0.17sec. The Mini needs the most steering correction.

Test 4: Lateral g
I’ve said it before and I’ll say it again: four-wheel drive gives you traction, not grip. At least, I thought I knew that.
Yet the two cars that displayed the least lateral grip around our wet circular track were the Mini and GT86. Two-wheel-drive. I think it’s because when they push wide, more power only makes things worse. That and the GT86’s slow stability control system.
However, with the other cars, great stability is garnered by their four-wheel drive systems. When one axle lets go, they apportion power intelligently to the opposite end and then grip is regained.
For the most part, they’re accompanied by excellent electronics so that none of them is a stranger to the high side of 0.6g. However, here the Golf R – hitherto merely a near front-runner – comes to the fore. That it can maintain a lateral g figure of 0.665g is unsurpassed here. The next best is Nissan’s GT-R, whose powertrain finally reveals its impressive shuffling capabilities.
The rest of the 4wd cars are at the 0.62sec-something mark, but that’s way ahead of the 0.5sec-something of the 2wd cars. Although tyres give you grip and 4wd gives you traction, without traction, you can’t exploit the fullest extent of the lateral grip.

Test 5: Lap time
The final test is the only one for which the stability control systems are switched off. We’ve tested them enough already and, come on, seriously, what did you expect when slides are in order? Besides, all of these cars go faster with the stability control switched off (we tried it), and this is, it’s true, as much a test of amusement as it is outright ability.
Scoring high on both fronts are the Golf R and 911 C4S. The 911 feels like it would make a terrific rally car. It’s easy to use its weight distribution on turn-in to keep the nose tucked in, and then drive it out on the power with a little corrective lock applied.You can do similar in the Golf, to an extent, only without the advantage of an engine hanging over the rear. However, the Haldex 4wd system’s ability to apportion power to the rear before the fronts have even relinquished grip is a boon. The RS4 has similar traits, too.
