The Mazda RX-8 comes in two variants: the MT with a six-speed manual transmission and the AT with the new six-speed automatic. The RX-8 drives like a sports car, with perfect 50-50 weight distribution for balanced handling and a high-revving engine. Options include leather trimmed upholstery, faux leather door trim, six-way power driver's seat, heated seats, lumbar support, a moonroof, heated mirrors, a six-disc CD changer, a DVD-based navigation system and an appearance package consisting of a front air dam, a rear spoiler and side and rear aero flares.For 2006, the RX-8 offers a new six-speed automatic in place of last year's four-speed. What's more, the automatic model gets a significant boost in horsepower. The six-speed automatic comes with steering-wheel mounted paddle controls for semi-manual shifting.
