I'm certain that is contributing to its stellar lap time ^_^
Absolutely. I estimate a good DCT could contribute about 5 to maybe 10 full seconds on an 8 minute track vs a MT. When I run some acceleration simulations with CarTest I will use DCT type shift times <.05 seconds (despite Nissans official stats on shift times .2-.5 seconds - totally wrong). I have not run and simulatons yet becaue you need a lot of acceleration times to compare and I have only seen a 0-60 figure.
