Ultima Sports Ltd

The car won many races and championships in smaller series, being driven by Noble and Ted Marlow.

This is the only way to receive such a vehicle in the US (including a "rolling body" fully constructed minus engine and transmission).

The preferred engine supplier for Ultima is currently American Speed, a company that specializes in re-engineering Chevrolet V8s for increased performance.

In 2006, Ultima beat their own 0–100mph-0 record set in the GTR640 with the GTR720, again using an American Speed SBC engine but now with 720 hp (540 kW) of power.

[citation needed] The vehicle was also driven to and from the test track on the public roads as proof of its road-going ability.
