Ultima Sports Ltd. is an elite British sports car manufacturer renowned for its extreme lightweight design and powerful performance, headquartered in Hinckley, Leicestershire. The brand’s origins trace back to 1983 when it was founded by freelance car designer Lee Noble. It was later fully acquired and restructured by the Marlow brothers into Ultima Sports, consistently adhering to a philosophy of being “born for the track.”
The company produces a limited number of hand-built units annually, with cumulative production reaching only around 200 vehicles. From serving as McLaren test mules to appearing at the Goodwood Festival of Speed and featuring in the Forza video game series, Ultima has maintained an undeniable presence among the UK’s small-scale domestic sports car manufacturers. Its model lineup is distinguished by a unique DIY kit culture, allowing enthusiasts to assemble their own ultimate supercar in their home garage—a vehicle capable of rivaling top-tier supercars in performance.
The Ultima story began in 1983. Inspired by Group C racing, Designer Lee Noble created the first Ultima Mk1. This car used a large number of Renault parts, equipped with a 270 horsepower V6 engine, made a successful debut on the track. Over the following years, Noble gradually developed Mk2 and Mk3 on the basis of Mk1, but in 1992, he chose to transfer his Noble Motorsports Ltd. along with the manufacturing rights of the Ultima brand to his friends Ted Marlow and Richard Marlow brothers.
After the Marlow brothers bought the Ultima brand, they re-established Ultima Sports Ltd., their goals were grander—not only to be faster than opponents on the track, but to create the ultimate street car that can be legally driven on roads. They incorporated endurance racing experience into the Mk3 and launched the iconic Mk4 model, adopting two methods of selling outward: loose kits and finished cars, thereby establishing a low-barrier, high-flexibility business model distinct from other supercar manufacturers.
Seven years later in 1999, the Ultima GTR after long development was unveiled, announcing the brand's arrival at a true high-speed explosion. In 2005, then-company director Richard Marlow personally drove a Chevrolet small-block V8 engine tuned by American Speed, and pushed GTR640's combat power to the extreme, continuously refreshing multiple world production car acceleration and braking records, and instantly rising as a strong competitor for the world's fastest street car. In 2006, the 640 horsepower GTR640 version created a world record of 0-100-0 km/h in just 10.3 seconds; the GTR720 with a 720 horsepower Chevrolet V8 and a vehicle weight of only 990 kg further shortened the record to 9.4 seconds. In 2015, the GTR, having gone through 16 years of glory, officially ceased production, the succeeding Evolution series pushed extreme performance to a new height.
Ultima has always adhered to a lightweight mid-engine rear-drive structure. Most models of the brand provide two delivery forms—completely assembled kits by customers (currently the only way to obtain in the North American market), and finished cars assembled integrally by the factory that can be driven on the road directly.
Early Models (Mk1—Mk3 & Spyder Series): About 14 units produced from 1983 to 1989. Mk1 produced only one prototype car; Mk2 upgraded suspension and braking systems, produced 13 units in total; Mk3 went into mass production between 1989 and 1992, adopting fiberglass body for the first time. Spyder convertible sports car launched in 1993, Initially equipped with Rover 3.5 liter V8 engine, switched to mainstream choice from 1994 — GM 5.7 liter small-block V8 engine, production continued until around 1998.
Ultima GTR (1999—2015): The most iconic model series in the brand's history. GTR640 achieved amazing results on the MIRA test track: 0-100 acceleration 2.7 seconds, 0-161 km/h acceleration 5.5 seconds, top speed reached 372 km/h, overpowering Ferrari Enzo and Bugatti Veyron SS on the Top Gear test track. As the strongest in the series, GTR720 possesses 720 horsepower, 0-60 mph sprint required only 2.6 seconds, completing the entire 0-100-0 km/h test run took only a short 9.4 seconds. This series also appeared in games like Forza Horizon 3, second-hand transaction prices were between $45,000 and $85,000.
Ultima Evolution (2015—Present): Successor series replacing GTR, offering Hardtop Coupe and Convertible Can-Am two styles. Body is 4000×1850×1070 mm, wheelbase 2560 mm, net weight only 950 kg. Power options include 480 hp 6.2L LS3 V8, 700 hp 7.0L LS7 V8, and 1020 hp 6.8L Supercharged LS V8. matched with Porsche 6-speed manual transmission, 1020 hp top version 0-100 km/h acceleration only 2.3 seconds, top speed 386 km/h.
Ultima RS (2019—Present): Currently the brand's flagship Hypercar series. Design inspiration taken from 1980s Le Mans Group C racing cars, extensive use of carbon fiber materials inside and outside the whole car, dry weight strictly controlled at 950 kg. Power based on General Motors LT series engines — Base version LT1 480 hp, Advanced version LT4 650 hp, Top version LT5 800 hp, officially reserved upgrade solutions up to 1200 hp. matched with 6-speed manual transmission, 1200 hp version 0-100 km/h acceleration only 2.3 seconds, top speed up to 402 km/h.
Ultima almost does not disclose annual sales or per-unit profit to the public, the small holding company located in Hinckley, Leicestershire is equipped with only six employees, assets on books hold about 2.25 million pounds. cumulative production of the brand from 1995 to present is only about 200 units. However on the track, GTR has defeated Ferrari Enzo and Bugatti Veyron SS with extremely excellent lap times. its performance power-to-weight ratio once reached 737 hp/ton, dry weight as low as 950 kg, relying on a starting price of less than $130,000, it instantly became the value king challenging Bugatti in 0-100 km/h acceleration results. American famous actor and wrestler John Cena once owned an Ultima Evolution equipped with a 1020 hp Whipple supercharged 6.8L LS V8 engine, becoming a major showcase for the brand in the North American collector circle. after importing to China, the landed price was about more than 2 million RMB, but subject to low brand awareness and the hard-core threshold of pure manual transmission, it has always been in a state of almost no one asking.
Ultima's hardcore strength and core philosophy lies in discarding all unnecessary electronic auxiliary systems, no traction control and ABS (Anti-lock Braking System) provided for all models. chassis structure uses tubular racing steel chassis frame combined with high-strength aluminum alloy, driver cockpit mid-positioned, the whole vehicle makes choices only on pure driving feeling. powertrain mainly based on GM LT series V8 engines compatible, supercharged tuning and matching optimization performed by American Speed and other professional tuners. aerodynamics follows the road racing philosophy of extreme minimalism, ensuring downforce stability and controllability in all speed domains, no active wings or variable spoilers required. cockpit interior returns to the most primitive mechanical redundancy, roll cage, suede-wrapped steering wheel, and concise dashboard occupy the main view. the only comfort and tech configurations come entirely from customer customization—Air conditioning, navigation, and backup camera can be configured optionally, everything has the baseline of not violating the lightweighting foundation.
The UK headquarters serves as Ultima's global core hub, responsible for whole vehicle development, testing, and assembly. In the North American market, due to local regulatory restrictions, Ultima kit cars are the only legal channel for customers to obtain vehicles, thus cultivating an underground supercar DIY circle led by loyal American enthusiasts. Customers in other European regions can directly order finished vehicles, provided they pass compliance procedures meeting local safety and emission requirements.
Outside of the North American and European markets, regions with growing demand for high-end supercars, such as China, Japan, and the Middle East, occasionally see small orders, but delivery volumes are negligible and largely handled through remote contact with the headquarters. In 2007, the UK official launch of the 800 hp Ultimate Edition GTR offered both left-hand drive and right-hand drive configurations to actively engage supercar buyers globally. Overall, Ultima's overseas business focus has remained on the two traditional sports car culture hubs in Europe and America, and the company has never established branch production factories overseas.
As of 2026, Ultima continues to maintain a small-batch, highly customized hand-building pace, with global sales primarily focused on the Evolution and RS series. The RS series, launched in 2019, sustains relatively stable demand in North American and European markets. Meanwhile, the Hardtop and Convertible versions of the Evolution series remain choices for some old-school track enthusiasts. However, the manufacturer has not yet officially published an electrification or hybridization roadmap. In its future planning, the brand remains committed to the core combination of traditional V8 engines and manual transmissions, avoiding entry into the competitive pure electric supercar market at the expense of the extreme driving experience. As a testament to its persistence with the classic mechanical fuel era, Ultima is likely to remain active at the forefront of British racing culture over the next decade, continuing to provide hardcore car fans globally with a channel to hand-customize and assemble their ultimate cars from scratch.
