Mugen is a company that doesn't do things by half -- and lately Honda's tuning arm has been extremely busy.

The world's most skeletal car, the Ariel Atom has been given a power boost without the need for a supercharger. The result is a 270bhp output from its 2.0-litre Honda-sourced engine that makes it just about the fastest thing on four wheels. Alongside the Atom Mugen we drove the CR-Z Mugen -- currently a one-off tuned version of the hybrid coupe.
