This is the first Ultima GTR (T81GJF) as seen on www.ultimasports.co.uk and on the GTR sales brochure. The car was factory built by Ultima Sports Ltd in 1999, used as a prototype for the new GTR model range, tested at MIRA and featured as the factory GTR demonstrator.
This car also featured in Which Kit magazines (May & November 1999) EVO magazine Le Mans trip (March 2000) and was test driven by Tiff Needell on BBCs Top Gear in 2000 click GTR TV!
I purchased this rather special car in April 2007 and immediately drove it home circa 300 miles directly after buying it (with only 7,600mls on the clock). Even though I took it easy (honest), it was fantastic to drive! I would love to have built one myself, but business and family commitments prevented that, so I went for this very first rather special factory built example, with some very interesting history.
Currently running a 6.7ltr full race/dry sump spec Small Block Chevy, de-tuned via slightly milder cam to just 487bhp & 487lb/ft torque (on dyno) for reliability and drivability now with a smooth wide power band.
I am planning is to run the car in MSA Sprints, Speed events and obviously a few track days whilst enjoying the odd run out on the road in the meantime!
