So with with a nice layer of snow on the ground I took the IS300H to an empty car park to see if I could warm my self up with some nice doughnuts....Sadly it quickly became clear Lexus didn't want the IS300H to be associated with this type of immature behaviour :(
The TC kicks in regardless of what setting you put the car in, Snow, TC 'off', sport, manual shift. Worse than that it's not just the TC that kicks in, you can feel individual wheels been braked to try and stop the rear end from over taking the front.
Shame really, because the car is beautifully balanced, you can start a drift/donut really easily, and for about 1-2 second it all feels really controlled, but than the TC comes alive, and it becomes like wrestling some kind of bear (I imagine).
But it wasn't all just about trying to get an ASBO....Also tried 'snow' mode, which seems to lower the initial power delivery, and allows a bit more 'slip' before the TC kicks in. Overall very impressed how the car handled in slippery conditions, even with the eco tyres on :).
Still a shame the TC is so intrusive, but at least the car still looks good surrounded by a bit of slush.
