Absolute carnage! Exciting race with a real twist at the last lap, but I saw that one coming a mile off. A look at the crew chief's face 2 laps from the end was a real giveaway. Loved the sound of the Volvos. Presumably, they are a custom build? i know they are 180 degree crank but does anyone know the origins of the motor? If they are custom for the series, how did they get around homologation regs?
