The Ultima GTR is a super car manufactured by Ultima Sports Ltd of Hinckley, Leicestershire, England, and described by commentators as a supercar. The car was available both in kit form and as a "turnkey" (i.e. assembled by the factory) vehicle until early 2015, when it was replaced by the Ultima Evolution. 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 was also produced. Kit builders were 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 was the factory recommended standard, and this configuration was fitted to all turnkey cars.
Ultima focused their marketing efforts on record-breaking activities using a model equipped with a 640 bhp (477 kW) American Speed engine, called the Ultima GTR640, and subsequently, a 720 bhp (537 kW) engine called the GTR720. As a result, they established the following official, independently verified records for a production car equipped with road tyres and exhaust:
Due to its kerb weight of 990 kg (2,183 lb), the power-to-weight ratio for the GTR720 is 727 hp (542 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 or the Caparo T1. However, the Ultima chassis is rated for engines up to 1,000 bhp (700 kW) and some of Ultima's customers have fitted engines producing 1,000 bhp (700 kW) or more, for a power-to-weight ratio of over 1,000 hp (746 kW) per tonne, which is approximately twice the power-to-weight ratio of the aforementioned cars 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).
