Ariel is celebrating the Atom's 10th birth anniversary by introducing a more powerful and Mugen-tuned edition of the sports car.

The Ariel Atom sports car features no door, no roof and no screen. The first-generation Atom sports car, which was equipped with the Rover K-series engine, was launched in 2000. Ariel changed to the K20A-spec Honda Type R unit in 2003. In 2007, the car was switched to the latest generation K20Z Type R engine.

Now, the company has plans to manufacture a total of ten Atom Mugens. Ariel will manufacture the special editions in partnership with Mugen Euro, Japanese Honda tuner's European division.

The new edition will be more powerful as it will produce 270bhp, 25bhp more than the standard model.

Each of the ten upcoming Atom Mugens will feature a special livery and a numbered plate signed by the Mugen and the Ariel technicians who manufactured the car.

Ariel will take wraps off the Atom Mugen at the upcoming Autosport Show, which will take place from January 13 to January 16 next year.
