Had the fortune of racing one of these on a private road.
They are quick - not quite as quick as the 172 but very very close. I decided that I would follow and had too back off twice from getting close to him. 1st Time was top end of 3rd and then top end of 4th. Was rather frustrating really coz each time I had to back off he was obviously still accelerating and it just meant that I wasnt accelerating so he probably got the impression that it was even.
The 0-100 times confirm that it is slightly slower - not by much though....
Fast cars !
