Diesel-powered British supercar Trident Iceni promises 200 mph and 69 mpg

For the past few decades, various British engineers and businessmen have attempted to build sports cars under the Trident name with as much luck as a broken umbrella in London. Today, Trident announced it would finally show its production-ready car in public next month -- the Trident Iceni Grand Tourer, a diesel-powered machine that should hit 200 mph while returning 69 mpg on a variety of fuels. It could be fantastic -- if it's for real.

The latest version of Trident says it's using a 6.6-liter turbocharged diesel that combined with some undescribed system its calling Torque Multiplication that's good for 430 hp and 950 ft.-lb. of torque; those with additional pounds at their feet can pay for upgrade to 660 hp and 1,050 ft.-lbs. In the base version, the Iceni can reach 60 mph in 3.7 seconds.
