XENEX Motorsports

Xenex Motorsports is the designer and builder of the sensational new MX Speedster. 


Our cars incorporate the spirit and ethos of the legendary speedsters of the 1950’s – cars like the Porsche 550 Spyder and 365 Speedster – while adding better performance, safety, and handling. Our first model, the MX Speedster, is based upon the Mazda Miata MX-5 NA. XENEX commissioned acclaimed car designer Kasim Tlibekov and the design studio Tlibekua to develop a speedster re-body-kit for the MX-5 NA – the best-selling sports car of all time – and the result is breathtaking.


Xenex also creates custom-built race and sports cars like the BMW-Alpina 6.0 CSR concept car revealed at the 2021 Amelia Island Concours d'elegance

The MX Speedster

** ORDERS BEING TAKEN APRIL 2023 **


The purest, wildest, most extreme sports car has always been a speedster. Stripped-down to maximally reduce performance degrading weight – with little or no windshield and no weather protection – speedsters were dedicated solely to the sheer pleasure of high-performance driving. Xenex transforms popular sports car chassis into modern-day, high-performance speedsters. 


True Speedsters have been scarce in the past few decades, so in 2021 XENEX Motorsports commissioned acclaimed car designer Kasim Tlibekov and the design studio Tlibekua to develop a speedster re-body-kit for Mazda’s Miata MX-5 NA – the best-selling sports car of all time.  The result is the XENEX MX-Speedster.
