I have snow tires. They'd probably explode into shreds around 150 MPH.
I finally gave in, after all these years. A clutch is a serious nuisance in traffic on the hills here, and I wanted the girls to be comfortable driving it too. You can sequentially paddle-shift this if you want to, which makes it sort of like driving a motorcycle.
I got this used from a guy who, when he had a job, had six boy-toy cars. He needed to get out from under the lease. It's the V6 that they don't make any more. All the A3s are 4-cyl turbos now, about as fast but they feel like turbos. Press. Wait. Zoom!
Transmissions are interesting. We have 95% efficient, stepup/stepdown, continuously variable switching regulators. The MEs can only dream of a mechanical equivalent.
P&W, one of my customers, is sticking a gearbox into the middle of a jet engine, to better match the impedances of the turbines and the compressors. 32,000 horsepower through a fairly small gearbox.
