This time at Willow Springs, Randy Pobst is doing an experiment: What happens when you replace the 2020 Corvette’s high-performance Michelin tires with an inferior set? First he’s out setting a super-quick lap that makes full use of the ‘Vette’s grip and power. Then, it’s back to the pits for a refit with some inexpensive, low-end rubber. With advice from Tire Rack’s Matt Edmonds, Randy’s back out on the tarmac. See what a difference tires make. #MotorTrend #Corvette #TireRack #ad

BMW’s M Division used to make cars known for three qualities: rear-drive, high-revving naturally-aspirated motors, and slick manual transmissions.

To see if the spirit remains, Randy Pobst takes this bruiser out on Willow Springs for a fast lap. #TireRackHotLap #MotorTrend #BMW
