The Ultima GTR720 is a world record breaking supercar manufactured in the UK. Available either pre-built or as a self-build kit, the Ultima GTR is really the benchmark for home-build sports cars. The '720' in the title refers to horsepower. Prior to the GTR720's introduction Ultima's top spec model was the GTR640, also a world record breaker. Power comes from a mid-mounted 6.3 litre Chevrolet V8 driving the rear wheels through a 5 speed gearbox.
In July 2006, an Ultima GTR720 set four new speed records for a road car, breaking Ultima's own records. In road going form, with road tires, a GTR720 driven by Richard Marlow (Ultima's director) set the fastest 0-60 mph time (2.6 seconds), the fastest 0-100 mph time (5.3 seconds), the fastest 100 mph - 0 time (3.6 seconds), and the fastest 0-100 mph and back down to 0 again (9.4 seconds).
This puts the Ultima GTR720 ahead of legendary supercars like the Mclaren F1, Ferrari Enzo, Porsche Carrera GT and Pagani Zonda F for accelaration and breaking performance.
