I just came back from ice driving in Finland, 3 full days at the ice track.
31 918 owners there, majority of them was spent in a C2S to learn car handling and then driving C4S to learn the difference between RWD and AWD during drifts, then moved onto Turbo S and GT3RSs, also have time to do laps in a 918 and GT3Cup car.
Universal opinion among the 31 owners is that the C2S is an utterly shit car, at least on ice. Everyone hates the turbo lag. Not very noticeable in 1st gear, but when we went drifting the damn thing in 2nd or 3rd gear, there is no immediate power, it was basically full throttle then wait perhaps half a second before it comes on, but during drifts we need immediate power to adjust the car's attitude and we get no help.
Same with the C4S but it was more nimble and agile with the AWD setup, and forgiving too. I had no trouble hold a drift for complete circles after a couple tries, actually until I had enough, which I never managed to do in a C2S.
Granted we are all amateurs, relying on power more than car control to hold drifts, as the pros has no problem handling the car with ease. For us amateurs without too precise throttle control, we either spin out due to the sudden power surge or understeer because not enough power was provided, hardest for us to control. But granted, it was quite satisfying to do complete laps sideways in the C2S once we work around the shortcomings.
Everyone loves the Turbo S on ice, what a machine, not much turbo lag we can noticed, but also the fact that we can do much higher speed in it so that power delivery is less of an issue as we can rotate the car with weight shift by braking alone and than hold the drift with throttle, the driven front wheels helps to stabilize the drift angle.
My favourite is the GT3RS, linear power delivery means I have power whenever I was to, I get exactly what I want. It almost behaves like the AWD cars. During one session my son was having a demo ride with the pro, I was gonna wait in the pits for him to come back, but I cannot resist driving the RS so I went out can chase then down and managed to stay with the pro for a couple laps. Granted he was doing much more extreme drift angles than me but the fact that I can stay with him speaks volume about the RS.
The 918 wasn't the highlight of the trip, The RS is. I had about 10 laps in it, wasn't too hard to handle, behaves much more like a C2S on ice on turn ins, but the front wheel drive kicks in mid corner and can be driven around a drift as a AWD car. But everything just happens a lot faster, not a easy car to catch to hold a drift, needs very quick reflexes, my brain knows exactly what to do but my hands aren't always quick enough.
GT3Cup car on ice was another on another level, easier to drive than I had expected but the speed it can attained was scary. with 8mm spikes the grip was amazing but also means I can hardly drift the car, it just goes around on rails. Gonna have more time with the Cup car next month in Leipzig as I had signed up to do a Master-RSR course.
