Caterham took a bit of a risk in hiring Kamui Kobayashi to head its F1 efforts this season, but now that risk will start reaping financial dividends, albeit not on an F1 circuit. Caterham Cars has dedicated a ten-car limited run of Caterham Seven 250R Kamui Special Edition roadsters for sale in the F1 driver’s home country of Japan.

Quite simply, each special edition is a lightened and hardened version of Caterham’s Seven 250R, which packs 123-horsepower and 120 lb-ft of torque from its 1.6L Ford Sigma four-banger. That doesn’t sound like a lot, but fed through the car’s six-speed manual and limited-slip differential, the car is capable of sprinting to 60mph in 5.9 seconds and onto a top speed of 112mph

You probably wouldn’t want to go any faster in a car without a windshield anyway. That’s right; in place of said windshield, Caterham has fitted a wind diffuser. Other performance additions (or subtractions) include a race-ready roll bar and the lack of a passenger seat, so get ready to be quite lonely out on track.

Caterham adds some personal touches with “Kamui” lettering on the headrest and on the car's matte black racing stripe, along with various other Kamui logos within the gauges. The price for this limited edition roadster? About $58,800, plus tax.
