Let's make it simple! If you're on a racetrack that's not a drag strip and you don't need to shift down to second while completing a lap, you're either in the car with the most torque on the planet, or you're on the wrong track. Corners make life better and keep tire companies alive.
The Nürburgring is an obvious choice here, but look past Germany's historic tarmac in the woods and show us your candidates. After all, this is a very wide question for today's Kinja shootout.
