Exciting Green Concept Cars at Goodwood

Generously provided by Trident Vehicles

Trident has come up with a very different method of lowering carbon emissions - by fitting a bigger engine. The Iceni is powered by a front-mid-mounted, 6.6 litre V8 turbodiesel. This General Motors truck engine is 100 percent biodiesel-compatible, and drives an eight-speed paddle-shift gearbox. With 550 bhp and spectacular peak torque of 950lb ft, the Iceni R has a theoretical maximum of 230mph and can hit 60mph in 3.7 seconds. But with such a low-revving engine - at 56mph it's pulling just 800rpm in top - Trident reckons 50mpg is possible. Being run on E100 biodiesel, the Iceni's carbon footprint is potentially significantly smaller.
