Safety
Safety is our top priority
Each car is equipped with FIA certified roll cage, fire suppression system and top harness equipment. The design includes non mandatory safety extensions, including high energy absorption foams or safe fuel cell.

A true top class

Strength and reliability
All the elements of the car have been developed to withstand the challenges of gravel and tarmac rallying.
Reducing maintenance costs
Parts undergoing major wear and tear are standard and available locally (ball joints, ball bearings…).
Controlled engine cost
The engine is very close to its standard spec which allows moderate running costs and good reliability for high levels of performance.
Multifunction parts
Hub carriers and brake calipers are identical on all 4 wheels and compatible on both tarmac and gravel versions. Suspension triangles are also identical on both sides of the vehicle as well as on gravel and tarmac con gurations.
The only parts differing between tarmac and gravel versions are:
- Brake discs and their mounting bells.
- Interface between hub carriers and suspension triangles.
- Shock absorbers.
