Since the introduction of Mazda's first rotary powered car in 1967 - the R100, Mazda has continued the trend with Familia Rotary Coupe (known as the R100 overseas), the Savanna (RX-3), Bathurst-winning RX-7, and Eunos Cosmo.
To celebrate, the Anniversary edition RX-8 adds to the standard luxury model with unique leather and Alcantara interior, leather wrapped steering wheel, gear shifter and handbrake and specially-designed 40th Anniversary badging.
Handling and performance have also been tweaked with the standard fitment of Bilstein shock absorbers and a urethane foam-filled front suspension cross member.
High-gloss 18-inch alloy wheels, silver engine cover, a floating rear spoiler, sunroof and blue reflector fog-lamps are all exclusive to 40th Anniversary models.
This is in addition to the standard equipment found on the RX-8 which includes a premium Bose sound system, ABS with Electronic Brake-force Distribution (EBD), traction control, Dynamic Stability Control (DSC), cruise control, power windows and mirrors, climate control air-conditioning and six airbags.
