Thanks to a promotion organized by Mobil 1 — which sponsors both Tony Stewart’s NASCAR racecar and the McLaren Formula One team — Stewart and Lewis Hamilton will take part in what’s being billed as the “Seat Swap.” Stewart will drive the McLaren, Hamilton will pilot the stock car at Watkins Glen International raceway. The television special “Seat Swap: Hamilton vs. Stewart” airs on SPEED at 8:00 p.m. ET Tuesday.
