artur777:

 4.1 up to 100 km/h - very close to GT3

up to 200 km/h it will be 13,5 secs? faster than M5?

 

So would the price!
 

Anyway, it may be very close with PDK, but as the speed increases so will the distance between the gt3 and C2S x51. In the end x51 will offer great performance albiet less than a gt3 at close to the cost of one without all of the gt's advantages including a stronger residual.
