ABOUT THE SONIC

The SONIC offers affordable exclusivity, allowing you to craft your own fully customised one-of-a-kind project!

 

This iconic, lightweight, twin-seat sports car is now owned and produced by Equilibrium Kit Cars, having originally been designed by Stuart Mills of Mills Extreme Vehicles in 2008. It continues to boast a bespoke, low-mass, tubular space-frame chassis, double-wishbone suspension and mountings to accept the readily available Ford Focus powertrain. The kit's original styling was based upon the MEV Rocket’s curves, but with the addition of more practical weather protection from an enclosed glass fibre cockpit.


The unmistakable SONIC shape has now been reworked with fresh eyes and an increasingly inventive and technical perspective. The kit has been fully CAD modelled from the ground up, with the addition of a number of enhancements to give a beneficial update using modern manufacturing and design techniques.

 

All future engineering and metalwork production will be done in-house, and so special requests, challenges and modifications are welcome!
