Honda UK and Mugen Euro are developing a CR-Z Mugen prototype. Honda CR-Z Mugen

The CR-Z Mugen will feature enhancements to both the 1.5-litre i-VTEC petrol engine and the Honda IMA system to boost power and torque, while bespoke brakes and suspension will be fitted to improve the chassis dynamics.

Official performance figures haven’t been revealed, but Honda said the CR-Z Mugen would offer Civic Type-R performance, which has 238bhp on offer.

At this stage, the CR-Z Mugen is being developed purely as a one-off prototype, with no plans for a production version.

Hiro Toyoda of Mugen Euro, said: “We wanted to extend the performance of the CR-Z.

“It is already a fun car to drive, with an excellent chassis, but we thought that with more power and enhanced torque delivery it could be even more exciting.”
