In latest issue of German AMS is 458 Italia compared with MP4-12C. 458 won in points. BUT... MP4-12C is a faster car.

458 Italia

0-100:  3.5s

0-200:10.4s

0-260:19.2s

 

MP4-12C

0-100: 3.3s

0-200: 9.2s

0-260:16.7s

Also 458 is with almost 1550kg around 70kg heavier then MP4-12C. Another interesting issue MP4-12C DCT is geared a la recent Porsche PDKs-that means that 7th gear is used a overdrive. On 458 situation is totally different, 7th is power gear(max is in 7th) and 5th and 6th gear are relatively short in comparison.
