Isn't the 458 aluminium bodied?
Anyhow, whilst discussing the GT2RS on another board someone posted a link to some performance figures for the 458 which are outrageous...
Weight: 1533 kg
Top speed: 328 km/h
0-100 km/h in 3,3 s
0-160 km/h in 6,5 s
0-200 km/h in 9,7 s (!!!)
0-250 km/h in 16,0 s (Enzo: 16,1 s)
400 m: 11,0 s (213 km/h)
If accurate, they are all fairly amazing - pretty much as fast as an Enzo and taking the 'baby' Ferarri's performance to an entirely new level.
The 0-100mph (160kph) time of 6.5s is 0.3s quicker than a 997 Turbo S, despite the Turbo S getting to 60mph 0.4s faster... so the 458 covers 60-100mph 0.7s faster than the Porsche... astonishing.
For perspective, a McLaren F1 was timed at 6.3s for 0-100mph by Autocar back in the day.
Not sure how the Scuderia/Stradale version can be significantly faster than that.
