The KR features not only revised styling, but also a slick aero package. SVT engineers spent a lot of time in the wind tunnel perfecting it, and it's said to provide 31 percent more downforce and actually yields a slight improvement of 0.4 second from 0 to 150 mph. Aside from the obvious hood, the KR sports a thin, aggressive carbon-fiber front splitter and utilizes the rear wing from the V-6 Mustang to round out the stable, slippery package. "You have to experience the new KR at speed in a curve to feel the difference," says SVT Product Design Specialist John Pfeiffer. "It has an absolutely minimal aero movement of just 54 lb-ft at 120 mph, a 92-percent improvement versus the GT500. That's central to its confident handling ability because it's just as happy at 120 mph as it is at 60."
