Caterham has built a special version of the Seven 360R for the British Royal Air Force. The one-off sports car uses recycled helicopter parts, and it’s all for a good cause.

The British boutique sports-car maker is known for its hardcore two-seaters that strip the driving experience right back to the bare essentials, and its latest creation adds a unique angle to this recipe.

The 360R you see here is not only capable of messing up your hair and facial expression, but also contains parts from a Puma HC2 military helicopter.

The vehicle is a joint project between the British Royal Air Force, Caterham, Mission Motorsport, and the Royal Air Force Benevolent Fund.

It’s meant as a tribute to the men and the women who flew the Puma helicopter during its service life, and also aims to raise money for charity. What makes it so special are the parts from Royal Air Force Puma XW232 that have been used in various areas of the car.

The aircraft came to the end of its 50-year service life, and the aluminum skin from its tail boom and doors has been turned into the exterior body panels of this very special Caterham.

It has been left in the same condition as it was on the helicopter for added authenticity, and the rest of the car has been painted in NATO Green to match. The result is a pretty unique and slightly rough look that suits the car very well.

On the inside, the quilted soundproofing from the aircraft now lines the door panels and also finds use as cushioning for the two carbon-fiber seats.

Even the evacuation instructions are still visible, and the interior is finished off with a specially built dashboard. Instead of normal switches, the driver can now make use of military-grade switchgear from the aircraft.

The startup sequence has also been altered into a three-stage ignition process just like on the helicopter, and the Puma’s navigational clock takes pride of place on the dash.

As a final touch, the car’s battery is now sitting inside an old ammunition box under the long hood. Royal Air Force engineers and Caterham staff jointly assembled the vehicle, and unlike many limited sports cars that disappear in museums or private collections, fans of the brand will have a real chance of owning this one.

The purpose of this one-off Caterham Seven 360R is to raise money for injured service men and women, and it will be auctioned off soon.

The lucky winner not only gets one hell of a cool car, but also supports a worthy cause in the process. The teams behind the project are hoping that it will raise more than £100,000 (P7.41 million) when it goes under the hammer.
