Not many people have heard of Radical, but they still hold the record for fastest (production car) lap at the Nurburgring with the SR8LM. In fact, EVO Magazine found that the $220,000 dollar 530-horsepower Radical RXC Turbo 500 would beat a $1.3 million dollar, 903-horsepower McLaren P1 around the Anglesey Circuit. So of course as manufacturers are dropping new science projects off at the Geneva Motor Show, Radical decided it would be a good time to show off its new RXC Turbo 500R.

Like the P1-beating predecessor on which it's based, the 500R has a funky F1-like shape and gullwing doors. Its edge comes from an engine tune that helps it make 600 horsepower. The first 21 Turbo 500Rs (the Nurburgring is 21 kilometers long) will be special editions featuring bare carbon and angry orange accents. The extra power from the twin-turbo 3.5-liter EcoBoost isn't the only thing that earns this Radical an extra "R" at the end of its name; the car also features aerodynamic upgrades that address issues that hurt the SR8LM's already world-beating performance during its 2009 record run. We can only wait until a lunatic with steel nerves and $239,000 comes around to see how these changes play out on the track.
