I know everyone is throwing out numbers like the G80 is 500 pounds heavier but its really not  a lot of it comes down to what the added weight is doing and I think some of it is added engine bracing which should help and the car being wider probably adds some weight but helps with grip as well. A decent chunk of it is probably to meet increasing safety standards which is unfortunate...I don't think anyone is buying this car for the crash test rating  |
Speaking about throwing numbers, according to SA/AMS to
M2C was 9 seconds faster around the 'ring than the
M2 they tested for a 60kg (132lb) weight gain which translates to a 6.7% improvement in power-to-weight. Most of that weight gain is from the engine, wheels, brakes and added bracing.
The weight gain of the G8XC over the F8XC will be more in the 300~350lb range for the RWD, which is quite substantial, especially considering that most of that weight is on the front axle. This translates to a ~5.7% power-to-weight advantage over a F8XC and only ~1% over a F82 M4cs. This will be even worse for the AWD version which will be 400~500lb heavier than the F8X. Further, the extra weight does not come from what they've added over the F8X, the added weight comes from what they have not removed.
