Todd, why do you think the 1.6 is significantly more difficult to drive at the limit? Is it primarily the compromised geometry when the car is lowered? Now that we an get more camber up front without going so low, might there be a net benefit from running a bit higher? At the moment our cars are fairly high but the control arms & steering still start on the wrong side of horizontal, but we can't go up much more and still get enough rear camber. So again we are stuck between compromises and can't evaluate the trade offs between geometry and overall height.
Personally I don't think the car is significantly harder to drive. If anything it just reacts quicker, so your reflexes and car control better be on point.
That being said, and this has been brought up before, I feel the car is harder to race, maybe that is what Buras was trying to say? We'll see what he responds.
It is VERY hard to defend a position in a 1.6. If I take a defensive line into a corner, I will be lower in the rpm curve and the lack of torque will kill me on exit - I will very likely be passed on the straight. On the other hand, if a 1.8 takes a defensive line ahead of me, he can use his torque on corner exit to maintain his position. Because of this, there are some corners on every track where I will simply not attack a 1.8, even if I get a good run, because I know I will lose the side by side drag race off the corner and just slow us both down.
I agree with the majority of the poll, the 1.6 needs something, but not much.
