The car is available as the Iceni Magna (fastback) and Iceni Venturer (estate) and is powered by a 6.6-litre V8 294kW/948Nm turbodiesel driving through a six-speed auto. Trident claims 0-100km/h in 3.7sec and 306km/h.Phil Bevan, designer and founder of Trident, said: "Trident cars deliver incredible speed, performance and fuel-efficiency, achieved through our unique torque multiplication technology."The Iceni has a claimed fuel consumption of 4.1 litres/100km. Bevan said the key to the Iceni's range was a combination of low revs and increased torque. For example, at 112km/h the sports car is running at only 980rpm.
