This is the follow up to the limited-run F12tdf, which had 770bhp to the 812’s 789bhp, but which also had a somewhat wayward chassis as it tried to hustle those horses. While that was a limited-run model, the 812 Superfast is a full production car, except it also gets the F12tdf’s rear-steer system, the same vast front tyres and more power. Which ought to make it scary on road or track.
