The Ultima Evolution is a limited production sports car built by British automobile manufacturer Ultima Sports. It was unveiled as the replacement for the Ultima GTR on 9 April 2015.[1] It is sold both as a kit car, which the buyers build themselves, or as a complete vehicle, built at the factory, and is available in either a coupé or a convertible bodystyle. The range-topping supercharged LS-powered model is reported to cost £95,995 ($122,332).[2]
Specifications
Engine
The Evolution is powered by 3 different engines, all derivatives of the LS based GM small-block engine.[3] The power outputs of these three engines are as follows:
- 6.2 L LS3 V8: 358 kW (480 hp)
- 7.0 L LS7 V8: 522 kW (700 hp)
- 6.8 L supercharged LS V8: 761 kW (1,020 hp) and 1,247 N⋅m (920 lb⋅ft)
The engine is mid mounted and the car has a rear-wheel-drive layout.
Transmission and suspension
The Evolution is equipped with a 6-speed manual transmission manufactured by Porsche and mounted longitudinally on the car.[3] The car uses double wishbone suspension on the front and rear axles, with coilover springs that allow for adjustment of bump, rebound, and ride height.[3]
Chassis
The car's chassis is a tubular steel space frame panelled with 5251 aluminum alloy, and has a built-in roll cage for structural rigidity and safety. The car's body is made out of glass-reinforced plastic, with optional carbon fibre wing mirrors and front splitter.[3]
Wheels
The Evolution is equipped with 18-inch (460 mm) forged alloy wheels with an optional 19-inch (480 mm) upgrade available. The tyres are manufactured by Michelin with codes of 245/35 for the front and 335/30 for the rear. The brakes are vented discs, with a diameter of 323 mm (12.7 in) at the front and rear.[4][3]
Interior features
The Evolution's seats and dashboard are finished in leather and Alcantara depending on the selected options. In place of a center console, the Evolution features a large, stainless steel gear lever and handbrake. The in-car entertainment system and optional satellite navigation system are manufactured by Alpine Electronics.[3]
