Re: Motorweek: 335i road/track test
Not really. It's industry trend unwritten rule to make cars to understeer for safety reasons.
To induce oversteer, 4 to 5 brakes, combined with a hard lock a la B. McLaren,J. Rindt, E. Fittipladi or F. Alonso.
Should be left to F1 drivers tough, since this could be criminal, literally.

Re: Motorweek: 335i road/track test
I understand understeer is induced purposely by auto manufactures to save many a novice driver from him/herself when they are pushing the limit of a cars capability. Otherwise that would be gross negligence exercised on their part. The way I should have put it probably should have been the fact that they switched DSC off and the car still understeered a good deal; more for the driving enthusiast that takes his car to the track, dont' have to worry as much about ending up in a ditch because of one misguided reflex.
I agree though oversteer should be left to the pros, I doubt many have the nerves to tolerate such extreme motion behind the wheel.

Re: Motorweek: 335i road/track test
It is hard to judge the amount of understeer especially when the driver is not taking the apex.
I would say there is reasonable understeer when you take the apex and use the entire width of the track, but judging from the series of events that occurred and when the comment was made- I would say, yes there was a bit of understeer but the comments were grossly exaggerated.
The other point worth mentioning is the tire configuration along with the various tire pressures. The staggered configuration also implies different mechanical grip levels between the front and the rear tires. Excessive front tire pressure relative to the rear will also contribute to understeer conditions as well.

Re: Motorweek: 335i road/track test
Interesting... Did anyone notice how when on the track the driver braked into the turn and the brake lights came on, and then another set of lights next to the brake lights came on? Anyone notice this? Never seen it before? What would trigger those lights to come on?

That lighting system is standard all on modern day BMW's. The system features two brake lights, the first coming on for regular braking (more or less), while the second light indicates hard braking.

Bruce's explanation is totally right.
I noticed that too... saw this system at work for the first time in this video...

I moved your post to the start of this thread.
I remember seeing on a pre-facelift 7er... Way cool.
