The Ultima Evolution is a limited-production British sports car from Ultima Sports of Hinckley, Leicestershire. Announced in April 2015 as the replacement for the Ultima GTR, it is a mid-engined, rear-wheel-drive machine with a tubular steel space frame and a glass-fibre body, sold either as a kit that the buyer assembles or as a complete car built at the factory. Its engines are all General Motors LS-family V8s, tuned from about 350 to 1,020 bhp.

From a kit-car racer to a supercar

The story begins with Lee Noble, who built the first Ultima in 1983 while still living at his parents’ house, as a car for the 750 Motor Club’s kit-car championship. When other racers asked to buy one it became a cottage industry. The first cars used Renault V6 engines, but customers soon wanted Chevrolet V8 power. In the early 1990s Ted Marlow bought the rights and tooling, and the company developed the Ultima Sports, then the open Spyder.

The sharper-styled GTR replaced the Sports in 1999, alongside the open Can-Am. The GTR is the car the Evolution grew out of: Ultima says the new model is the product of more than 15 years of research since the GTR and Can-Am were launched, and the Evolution keeps their Le Mans Group C-inspired body shape. The chassis, however, was developed further for performance, road holding and safety.

What is new on the Evolution

  • Engines: LS-based General Motors V8s. The top 1,020 bhp engine is supercharged and, according to New Atlas, supplied by American Speed, the specialist that re-engineers Chevrolet V8s for Ultima.
  • Cabin: leather and Alcantara trim, a carbon-fibre centre console with a stainless-steel handbrake lever, a flat-bottomed steering wheel with wireless controls, and an Alpine stereo and navigation system.
  • Everyday touches: LED headlamps and tail lamps, rear parking sensors and a reversing camera set into the rear grille.
  • Choice of body: coupé or convertible. The Evolution coupé and convertible keep the body styles of the GTR and Can-Am respectively.

The numbers Ultima claims

Ultima sells its cars on records. For the Evolution it claims 0–60 mph in 2.3 seconds, 0–100 mph in 4.9 seconds, 0–150 mph in 8.9 seconds, a standing quarter mile in 9.2 seconds at 156 mph and a top speed above 240 mph. New Atlas notes that Ultima describes every one as a world record and that the times were not independently verified when it reported them in April 2015, so treat them as the maker’s figures.

The GTR laid the groundwork. According to Wikipedia, a factory-built GTR720 with an American Speed V8 recorded 0–100–0 mph in 9.4 seconds on road-legal tyres, timed with GPS equipment by an official from Guinness World Records timekeepers Datron. The same car lapped the Top Gear test track in 1 minute 12.8 seconds, unofficially but with an independent timekeeper present, and 1 minute 9.9 seconds on slick tyres, which Ultima points out beat the 1:10.7 of Michael Schumacher’s Ferrari FXX. Sources differ on the date of these runs (Wikipedia gives 2005–2006, Silodrome 2009), so we do not date them here.

A test bed for McLaren

Ultima’s steel space frames have also served as development hacks for far more expensive machines. English Wikipedia records that McLaren used two Ultima Mk3 chassis to test the gearbox, central driving position and BMW V12 of its F1, and later an Ultima GTR to try out the linked hydraulic suspension of the MP4-12C. Goodwood notes that Gordon Murray, the F1’s designer, used two Ultimas as development mules.

Kit or complete car

Ultima supplies its cars primarily as components for an owner-builder. In the United States that is the only way to receive one, including a “rolling body” built up to everything except engine and gearbox; in Europe a complete turnkey car is available too. At launch New Atlas reported prices from £65,995 (about $100,000) and first deliveries expected in September 2015; Wikipedia gives £95,995 for the supercharged 1,020 hp car. Buying the kit part by part spreads the cost, as Silodrome noted of the GTR, and a second-hand V8 and gearbox can lower it further.
