HIGHEST SAFETY

LEVEL

Carbon monocoque reinforced by internal ribs and bulkheads. Carbon crumple zones

absorbing crash energy at front and side parts. Six point seat belts, neck restraints, integrated fire extinguisher system, poly-

carbonate windows and safety tank - we bet you have never felt so safe in a race car!

FIA CN class safety tests in the test center Cranfield Impact Center passed in spring

2013 with great reserve.

LOW RUNNING & RACING COSTS

Affordable pricing, long engine service intervals, low tyre consumption, competi-tive pricing of spares, substantial resilience against body damage - we know what it costs to go racing. We want to make it exciting and affordable.
