At the 2008 Detroit Motor Show information was given regarding the optional Mazda R3 package. The Mazda R3 adds a sport-tuned suspension with Bilstein shock absorbers and front suspension crossmembers filled with urethane foam.

Filling the crossmembers makes for a smoother ride, minimized noise, vibration, and harshness (NVH) and greater suspension control. On the visual side of the package, a rear spoiler, side sills, fog lights and sporty front bumper are added to give an aggressive appearance, along with 19-inch forged aluminum-alloy wheels with high performance tires. Inside, the Mazda R3 adds a 300-watt Bose audio system with Centerpoint surround sound and AudioPilot noise compensation technology, Bluetooth hands-free phone system, front Recaro sport seats with leather side bolsters, leather-wrapped parking brake handle and Mazda advanced keyless entry and start system.
