The Ultima GTR is a sports car manufacture by Ultima Sports Ltd of Hinckley, Leicestershire, England, and described by commentators as a supercar. The car is 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.
