Ultima Mk2

This is The second model produced by the company, with a total of 13 cars would be produced. Two of the produced cars were MK2 5000 race cars. The car would use an evolved Steel Square-Tubed chassis, developed from the Mk1. Ted Marlow, the eventual cofounder of Ultima Sports Ltd would buy the first Mk2, as specced with the original Essex V6. The Mk2 would eventually go racing under the "Ultima Mk2 5000" moniker, using an unused Formula 5000 Cooper-Chevrolet Small-Block V8, where they would find success, winning a huge number of races.^[1][2][3]

Chronology
Predecessor	Ultima Mk2
Successor	Ultima Sport

In 1989, the updated Mk3 replaced the Mk2.^[2][12] The Mk3 itself was heavily revised in 1992, becoming the Mk4 which was sold as the Ultima Sport. The Mk3 would make up half of Ultima sales by the end of its life because 13 of the 26 total Ultima Kits sold would be Mk3's. The car would be the final Ultima developed by Lee Noble. There would be a novel chassis made for the car, an Aluminium Tubular chassis, now fit exclusively with the Porsche G50 5-speed, used also in the Mk2.^[13] Ted Marlow and Lee Noble would establish Ultima Sports Ltd to build the Mk3. Even though the prototype of the Sport and the Mk3 RS Race Car would use an Inline 4 from a Darrian T90, there would be no standard option to have an Inline 4 in the Sport or Mk3.^[14]

Two Mk3 chassis were supplied by Noble Motorsport Ltd. to Mclaren Cars in 1991 to serve as test beds for the McLaren F1.^[15] Both cars were crushed, however, a replica of Edward has since by built for Mouse Motors by Lanzante Limited using an original BMW S70 engine.^[16]
