More after the jump....
This year's Ultima GTR record holder was upgraded with a 720 hp Chevrolet V8, and is now known as (what else?) the Ultima GTR720. The record setter was fully road legal, equipped with street tires, and outfitted with a standard G50 transmission. Amazingly, the record car has neither traction control nor ABS.
The ultralight Ultima GTR720 is a full two seconds quicker from 0-100-0 than the legendary McLaren F1 LM, and over 1.5 seconds quicker than a Ferrari Enzo.
The Ultima is sold in the U.S. as a kit car (see photo!)
Marlow's supercar is his daily driver and a company demonstrator, and was driven to and from the world record test site! A video of the record run is here.
