That's my modest answer for the skeptics and the haters which says - without impartial and reliable proof - that is "slow" or "slower than expected and bla bla bla..." and try to guess the "real numbers" - with which title...: we don't know - :
0-100: 6.0 seconds real
0-200: 19.9 seconds real
0-250: 38.1 seconds real
Sorry guys: your pessimistic theories needs evidences before to talk too much... Ok, it's not powerful as a Lamborghini or a light weight car as a Lotus, but this OPC is still a good car and an amazing hot hatch, that does his job for everyday drive, or sunday free fun on mountain road ("average legal..."), or for trackday beginners which doesn't want to win the Le Mans 24 hours and doesn't want to demostrate nothing... and just wants a car to have fun, and then come back home with wife and kids, and go shopping without necessity to have 2 cars ;-) It's built for this, and it can do this very well: is still a stock car for hobby people... why you take everything so serious as every car should be "a racing car for The Stig..."?! This car is well done: faster and preciser than you can expect. The heavy weight anyway has got a small advantage: is less nervous to drive in extreme conditions, and so it's easier 'cause is smooth.
By the way: what's the point of this silly discussion? Don't lie to ourselves: except for the german autobahn, when you'll be able to find the space to find out the accelerations time...?! Useless
