Luxury Japanese carmaker Lexus has chosen to unveil its two-door LF-A supercar in new racetrack trim, ready for this weekend's 24-hour race at Germany's famed Nurburgring circuit.

The 330km/h coupe has been pictured mostly in the past couple of years as a heavily disguised prototype. Spy photographers have caught it testing on roads and tracks in Europe and the United States.

Lexus has raced the LF-A before - but it has never been seen dressed up like this.

The cars are wearing the colours of the Gazoo Racing team, made up of professional drivers, Toyota test drivers and dealers, and a driver known only as "Morizo."

Gazoo is a Japanese market, Toyota-owned, e-commerce website that aims to "create a new relationship between automobiles and people in the new IT era."

Lexus will run two LF-A racers in the endurance event, both lighter than the planned street-legal model and powered by a V10 engine developing upwards of 375kW, or 500bhp. Modifications for the race include safety equipment and long-range fuel tank as well as a rear spoiler and other aerodynamic features.

Lexus says it is using the Nurburgring to fine-tune technology that will appear in the road-going LF-A when it goes into production in Japan next year.
