I doubt that Kubica and Webber are some 40-50 kgs heavier than Heidfeld.Quote:

As far as I know Brawn GP have a KERS optimized car running without KERS, it doesn't seem to handicap them in any way.
Not having KERS on board gives the possibility to use 25-35 kgs of ballast compared to a KERS car, this means a slightly better handling and better tire conservation during the race.
Having KERS on the car means you get a somewhat less good handling (especially under braking) than the non KERS car, maybe a bit more tire wear but not sure and +60KW of power for 8% of a lap.
IMO the FIA should have brought the minimum weight to an even higher amount but even then someone will whine about being disadvantaged because of his height.
Didn't Honda construct two chassises during '08 - one for KERS and another one not? Current BGP is obviously using the latter one.Quote:

If a "KERS-car" and a "non-KERS car" both run without KERS, then I think the latter one may have an advantage as the KERS-compromises haven't been taken into account in design and it has been possible to concentrate more on performance maximizing. Well, at least this is my interpretation. :)
I wonder, how much is it going to hurt BMW's progress if they need to prepare two different cars for each GP weekend. Or isn't it a big deal at all? Another relatively unknown case that needs to be found out in the future.
Why speculate when you can see for yourself :p :Quote:

Any source for they having to different cars one optimized for KERS and one for racing without KERS?
That is all nice and well from a belletristic POV but it doesn't explain the actual differences and how that would influence the performance of the cars.Quote:

Well, I have been reading a lot of things over the winter, so it may be possible that Honda and Toyota have been mixed up in this regard.Quote:

Renault with its heavy front end was the first one to announce their decision to run with KERS at Melbourne. At the other end of the scale we have the biggest doubter Toyota with its short front end and more rear-biased weight balance. Coincidence?Quote:

Don't know, all I can say is that you can't tell the weight bias of a car by only looking at it because it's shape is dictated by aerodynamic laws in the first place.Quote:
