I don't think he drives like that any more, the 05/06 Renault was tailor made for Alonso's under steering style .

[quote="timbo"][quote="mahesh248"]The article talks about over-steering drivers putting in a lot of steering and happy to do so, but I have seen Alonso doing the same with an Under steering - Championship winning Renault in 2005 and 06 .[/quote]
That's different "lots of steering". In an oversteering car you have to be ready to work with the steering a lot -- not in amplitude but in frequency, putting a lot of correction as you go. OTOH if you have understeer you have to turn wheel more for the same response.
And as far as Alonso goes, he seems to prefer a little more steering ratio than other drivers, so a lot of that impression is simply cause he's having a slower steering.[/quote]


Yea , that is right , Thanks

I was actually talking specifically OF his 05/06 Renaults... :lol:

You can see that he just throws in the steering. Take for example Turns 1, 4 and 9 here - it looks as if he's turned a bit too early; but then closer to the apex he just slams a lot of lock on; quickly.

Have to be careful about how I phrase this. It's not the understeer in and of itself that's the benefit, it's having less load transfer on the rear axle (assuming you're RWD and have quite a bit of output power) than on the front. Understeer does typically come with that directional change.

Anyway, you will be able to get on the power earlier because your inside rear tire will have more load on it - and generally on a road course car that is your limiting factor. Of course the driver has to recognize that as well, that they have to sacrifice a little mid corner to get the exit speed - and exit speed is king. If they are stubborn and just keep trying to push the hell out of the center and botch their line, then yeah you'll have a completely screwed corner - exit included.

“A lot of the performance limit of a car is set by stability; if your driver can't hang on to it, you have to introduce understeer in that zone. If you have a driver better able to deal with oversteer in zones that induce it, you'll have a less understeery car elsewhere and therefore more total grip over the whole lap. The great drivers – Ayrton Senna, Nigel Mansell, Michael Schumacher – all had that ability. Like-for-like, compared with other drivers, they wanted more front end.”
Few things you have to think about. First, it's ridiculous to just describe a car as just "neutral" or "understeer" or "oversteer." Balance and feel are a function of speed, longitudinal acceleration, lateral acceleration, and even vertical acceleration. You could be understeer on the brakes, neutral in pure steering, and oversteer on throttle. Or even in pure cornering you could be neutral, even understeer in slow easy maneuvers and oversteer in quick transitions. Beyond that, what drivers call "understeer" or "oversteer" is open to interpretation.

Second, a truly "neutral" car to many drivers probably won't feel "neutral." I could write a paper on this but in short, the driver's job is to poke and prod at finding the limit. On a RWD car a good bit of this is feeling corner exit out with the throttle... and on a "neutral" RWD car with a lot of power it will be VERY easy to provoke it into stepping the rear out or spinning. "Neutral" can very much feel like an "oversteer" car, and to get a "neutral" feel you will probably need to dial in some amount of understeer.

For that reason, drivers who can cope with a car that's very finely balanced and easy to piss off, will have engineers get the car closer to a theoretical max. A virtual driver, as the article implies, can be tuned to be ridiculously good at such things, moreso than any human.

Then you have certain cases where you need heaps of understeer to go fast just because it's the only way of getting power down on exit.

Or you can drive a porsche 930 and be in oversteer in every condition listed above.

He adapts his style to suit the car, that is why he is so quick. He drives the car how it should be driven.

I had read an article a couple years ago about it. Look how he changed his driving style from 06 to 07. It was night and day.

The 05 and 06 Renaults were chucked around like that because that was the fastest way to drive them.

Even after the mass damper was removed from his car, he changed his driving style by the very next race, and had clawed back the lost time in 2 or 3 races and still got the championship.

Yes that is true. Alonso knows and can adapt to the style that is needed to driver the car at hand. He's like a Blade master of cars.
