Audi A6 3.0 TDi quattro automatic - 233ps, 450nm torque, 225/55/16 winter tires. BMW 530d automatic - 218ps, 500nm torque, 225/50/17 winter tires. Both have turbocharged 3-litre diesel engines. Filmed in wet conditions. Audi had the advantage of quattro. BMW could run 7s to 100, but only on a sticky track and with wide summer tires. Audi 2007, Bmw 2005. Driven by me, used powerbreaking.
