manufacturer=DOME Co. Ltd.
class=Sports car
body_style=2-door coupeThe Jiotto Caspita is a prototype midship sports car designed and manufactured by Dome for a company named Jiotto in 1988. The car was billed as the "F1 on the Road". The original design of the car was done by Kunihisa Ito, who was the vice-president and chief designer of Jiotto Design Incorporated.

The first car was powered by a Motori Moderni flat 12, a detuned Formula One engine and then in 1990 was stripped and then rebuilt with a Judd V10. Both engines were transversely mounted, and powered through a 6 speed gearbox built by Weismann. The car first made its debut at the Tokyo Motor Show in the same year, but the project would die out in 1993 due to the global recession which meant lack of demands for supercars. With the Judd engine, the Caspita is capable of 577 horsepower (430 kW) at 10,750 rpm and a top speed of 199 miles per hour (320 km/h), while producing 283 ft·lbf (284 N·m) of torque at 10,500 rpm. The Caspita also features a 6-speed manual transmission, a 0-60 mph time of approximately 4.7 seconds, and a curb weight of 2734 lb (1240 kg).
