Ultima GTR

The Ultima GTR is a supercar manufactured by Ultima Sports Ltd of Hinckley, Leicestershire, England, available both in kit form and as a "turnkey" (i.e. assembled by the factory) vehicle. The design is mid engined, rear wheel drive layout, with a tubular steel space frame chassis and GRP bodywork. A convertible version called the Ultima Can-Am is also produced. Kit builders are free to source and fit a variety of engines and transmissions but the Chevrolet small block V8 supplied by American Speed mated to either a Porsche or Getrag transaxle is the factory recommended standard, and this configuration is fitted to all turnkey cars. Recently Ultima have focused their marketing efforts on record-breaking activities using a model equipped with a 640 bhp (brake horsepower) American Speed engine, which is called the Ultima GTR640, and subsequently, a 720 bhp engine which is called the GTR720. The Power-to-weight ratio for the GTR720 is more than 650 bhp (480 kW) per tonne, which is a better ratio than the Bugatti Veyron, Enzo Ferrari, Ascari A10, Koenigsegg CCX or CCGT (but less than the Koenigsegg CCXR) , and Saleen S7. However, the Ultima chassis is rated for engines up to 1000 bhp and some of Ultima's customers have fitted engines producing 1000 bhp or more, for a power-to-weight ratio of approximately 950 hp/tonne, which is approximately twice the power to weight ratio of the aforementioned supercars and nearly the same as the Caparo T1's (1170 hp/tonne, but this is a "dry" tonnage and the hp/tonne would be reduced once oil, coolant, gasoline, etc. are added, compared to the Ultima figures above which are "wet" weights).
