It’s been a while since we last heard from British sports car manufacturer Trident, the company behind the unique Iceni diesel-powered sports car. Today, however, the company has announced that it will be showing an updated version of the car, the Iceni Grand Tourer, at Salon Privé 2012 taking place in London early next month.  

The Trident Iceni, named after an ancient tribe that inhabited the area of modern-day Norfolk, England, Trident’s current home, is a low-slung sports car built in the same vein as other British classics, but with one major difference: it’s packing a 6.6-liter turbodiesel V-8. The mighty engine is sourced from General Motors and modified to run on biodiesel.  

In the latest Iceni Grand Tourer, the engine is tuned to deliver 430 horsepower and a staggering 950 pound-feet of torque. Trident says it's good for a 0-60 mph time of just 3.7 seconds and a top speed of almost 200 mph, but where the Iceni Grand Tourer really shines is in its fuel economy.

The company says that the Iceni Grand Tourer's engine runs at just 980 revs when the car travels at a constant speed 70 mph, such as cruising on a highway. In this way, it can return an average fuel economy of up to 57.4 mpg and cover a range of over 2,000 miles on a single tank of diesel.

If this sounds interesting to you, Trident will build you one for £75,000 (approximately $119,205), though the company hasn’t mentioned if left-hand drive versions are available. It has, however, mentioned that power upgrades for the Iceni Grand Tourer are available, including one kit that lifts output to 660 horsepower and 1,050 pound-feet of torque.

Salon Privé 2012 kicks off on September 5 in the UK.
