Trident Iceni 200 mph British eco-supercar re-appears at Salon Prive

The Trident Iceni is a bit different to your average 200 mph sports car: it is powered by a 6.6 litre diesel engine.

Its eco-credentials are that it runs on bio-diesel and is capable of unfeasible fuel economy: at 70 mph, it is said to achieve 68.9 mpg thanks to the fact that the engine is turning over at an absurd 980 rpm (if you think that is a typo, we really do mean less than 1000 rpm). Thus at the legal limit, the car is, literally, ticking over
We say re-appear because we saw it in prototype form at the 2007 Goodwood Festival of Speed, but then it disappeared, just like the Iceni tribe of Roman-era Norfolk that gave the car its name. Now it is back and apparently production-ready.

The engine comes from a General Motors truck, so it should at least be durable. The Iceni is an interesting approach, because it is exactly opposite to most modern thinking. Mainstream car makers are downsizing their engines in search of greater efficiency and greater economy. Trident thinks a big engine that barely does more than tick-over actually uses less fuel. Does the little company in Norfolk know something the rest of the industry doesn't? BMW used to believe the same thing and had the BMW 525 eta in the 1980s, which used a big engine running very slowly, but that idea seems to have gone out of fashion.
