But don't let the low output fool you as the 2,750mm (108.3-in.) long sports car weighs in at just 564kg or 1,243 pounds which translates to a power to weight ratio of 5.4kg/hp. SEMCA claims that the F16 can sprint from rest to 60mph (96km/h) in only 5.5 seconds while the roadster tops out at 110mph or 177km/h.
