Well I did a few laps with these cars and wow.... awesome!
200BHP seems quite easy to handle, I didn't spend much time with them.
260BHP is a very nice car: I did a race session on Brands Hatch with it and I find it a nice challenging car. It's drivable, with it will trick if you are unfocussed. I like this car most of the three.
320BHP was just a bit too much for. I just couldn't deal with the major understeer at Brno. Even if my front turns into the corner, my rear just drags it away in a straight line. These cars are the real challenge, but they are a too big a challenge for me right now.
I also like the fact that you can actually lose your wheels, even online, which will blow your race. Adds a challenge for, as I can now not afford to hit the wall too hard.
I have yet to test the two new tracks, Estoril and Imola, but that will not remain for long.
Good expansion! (although not fullly debugged yet)
