A small British company called Trident has produced a two-seater sports car called the Iceni. The Trident Iceni is the only Diesel fueled car that made it into the line up. Powered by none other than a GM sourced 6.6-liter V8 turbo diesel engine. The V8 produces 520 lb/ft torque at only 1800 rpm. That is enough power to propel the Iceni to 60 mph in 3.9 seconds and a top speed over 200 mph. Most impressively, the Iceni can do all this with 60 mpg and 1,000 miles on one tank and it runs on pure vegetable oil. The Iceni is also the only car in the line up that will unfortunately never make it stateside.
