how precise is a piece of string?
Excuse this first paragraph, this is just an aspie engineer being aspie..
"aluminium, carbon fibe and plastic" is hardly precise. Firstly, by carbon fibre, you mean CFRP and by plastic you mean a polymer the precise nature of which you do not divulge and I suspect that by aluminium you in fact mean an aluminium alloy. Furthermore you make no mention of the precise P within which the CFR is contained nor the nature of the CFs and their orientation nor do you mention the precise construction of the overall composite structure or the manner in which it is affixed to the other structures.</aspie>
An E92 M3 (as pictured) will do 0-60 in 3.9 seconds with M-DKG and ~4.1 without so I seriously doubt it's going to be slower to 50 than a car which takes 3.7 seconds to get to 37mph and 7.2 to 60, that would imply it does the 37-50 sprint in 0.4 seconds (assuming the slower manual box M3) and 50-60 in 3.1 seconds.
Yes, those numbers stack up don't they? Was my mum driving the M3?
I have nothing against the i3, I think it's an impressive car and it's commendable that BMW are pushing the boundaries like this AND I quite like the looks!
They only need to knock 95kg off the weight and 0.5 seconds of the 0-60, add 44mph to the top speed, give it wider tyres (say 205) and a proper driving position and ride height, bin the ABS and it'll be about as desirable as my current car (a 10 year old Clio :p).
