US Rallycross ace Tanner Foust has lost his World Record for reaching an in-door speed of 139.98kms/h (with a 560bhp OMSE Ford Fiesta Mk7 Rallycross SuperCar) to Finnish WRC star Mikko Hirvonen. The Finn used a Kart (750cc, 312kgs) to reach 140kms/h and, thereby, to replace the American in the ‘Guinnes Book of Records’.
