understeer

We started with understeer, aggressively chased that and ended up with a lot of oversteer.

John Martens, Delphi's project manager for ARS, says the system uses a yaw plane reference model similar to those of electronic stability control setups but adds a dynamic function that effectively reduces both understeer and oversteer at all speeds.

Oversteer, understeer -the technology sorted you out.

With the Aussie, who suffered with a touch of understeer on his qualifying lap, on Michelin tyres to Button's Bridgestones, the 11-10 looks top value.

It will also be the first model to use a new-generation electronic stability programme (ESP incorporating understeer control (CSV).

But there was disappointment for series leader James Courtney as the Australian could manage only the sixth fastest time after some set-up adjustments caused a touch of understeer.

When it does slide it's neutral on a dry surface and tends to understeer in the wet.

If, for some reason, a tyre pressure monitoring system, plus auto headlamps and wipers don't keep you out of the bushes, then standard ABS, EBD and Emergency Brake Assist should do, while plusher models also get ESP stability control and CSV understeer control.

It features air-conditioning, six airbags, front and rear electric windows, anti-skid control, stability and understeer control, heated mirrors, a CD player, keyless entry and a trip computer.

A Handling Pack includes ESP and traction control, understeer control and tyre pressure monitoring.

So if you're honking into a corner and get a bit of understeer (a frontwheel skid) the system sends power to the outside wheels and pushes it round the corner.

"I had understeer in the first stint so in the first pit stop I asked for some more wing and I think it helped so the middle stint was better, but I was still suffering a bit of understeer.
