Leading Edge Sports Car Company was a British car company based in Dereham, Norfolk established in June 2002. The company was dissolved in September 2005. It outsourced the manufacture of its cars to fellow Dereham company Breckland Technologies.

Leading Edge was established in 2002 by Paul Mickleburgh to market its first new car, the 190 and 240 RT in Europe and the US. The car was a lightly updated version of the Tommykaira ZZ, a popular car in Japan, but made in Norfolk, and it suffered from the Japanese recession and the company became bankrupt. The receivers sold the tooling and inventory to neighbouring Breckland Technology Ltd, run by ex-Lotus engineer Mark Easton, who continued to manufacture the cars and sold them on to Leading Edge to distribute from the summer of July 2002 at a price of around £26,500.

The car featured a mid-mounted Nissan 2.0 L twin cam engine (1998cc), producing 180 bhp (134 kW; 182 PS) at 6900 rpm and torque of 142 lb⋅ft (193 N⋅m) at 4900 rpm. Top speed was claimed to reach 140 mph (230 km/h) and accelerate 0-60 mph in 4.8 seconds. Its open-top body was glassfibre, with an extruded aluminium central tub topped and tailed by tubular metal subframes and weighed only 763 kg (1,682 lb).
