One of the activities we got a chance to participate in last weekend was a circuit drive on the skid pan at GM’s proving grounds at Lang Lang, here in Australia.
The two outer lanes of the skid pan were wetted down and our challenge was to get the cars around the course as quickly as possible. We travelled the outer ring half way round, then switched to the inside ring to do a full circle, then switching back outside again for another half-lap.
We did the exercise in Sportcombis and a convertible, but Swedish engineer and rally driver, Peter Johansson, had a go at it in the Turbo X. This quick circuit was filmed by one of the local TV stations for an automotive TV show.

I’m not sure what speeds Peter got to here, but in our runs (we drove in pairs) we were regularly getting up around 70 km/h on the inside circuit. That mightn’t sound lightning quick to you, but when you’re on the slick stuff it’s definitely fast enough to make a sweeping bend into a reasonably tight corner. It’s a constant task to keep looking ahead and stay on course.
In your head you feel like the car should be breaking traction at any point – but it never does. We had a fair bit of water on the surface and it definitely heightened your concentration, but the car never felt out of shape. The ESP isn’t overly obtrusive but it’s obviously working.
Saab may not have invented ESP but they’ve done a heck of a job developing and implementing it, making it a standard inclusion on the Saab equipment list. They recently handed it down to Holden here in Australia, too, and the same software is now standard on the top-selling Commodore range.
