Mazda Motor Company introduced two limited-edition models in Japan. The Roadster Turbo is the first factory version offering a turbocharged engine for the Roadster, known as MX-5 or Miata abroad. And Mazdaspeed created an enhanced RX8.

Mazda Roadster Turbo
Mazda Motor Corporation has added a new turbocharged engine model to its Mazda Roadster, the world's best-selling lightweight sports car. The limited edition Mazda Roadster Turbo goes on sale from the beginning of February at Mazda Anfini and Mazda dealerships throughout Japan.

The new Roadster Turbo not only delivers more power, but also provides high torque from a low-speed range to ensure a linear response to acceleration, based on the concept of "oneness between car and driver." Mazda has employed a turbocharged engine with an intercooler and tuned the chassis, achieving a high level of integrated balance in its powertrain under the concept. The specially-tuned low-down suspension with Bilstein dampers and large diameter 17-inch tires provide strong support for the wide range flat torque and powerful acceleration produced by the turbo engine. Further, exclusive equipment including newly designed aero parts and metal tone interior parts further emphasize the car's sports spirit. The new Roadster Turbo achieves a superb overall vehicle balance for enhanced driving pleasure creating a feeling of "oneness between car and driver." The new model offers a choice of four different interior packages and four body colors to meet the diverse needs of customers.

The new model is equipped with a turbocharged engine that starts up with excellent response from a low-speed range and produces flat torque over a wide range of engine speeds. Torque has been increased by over 20 percent compared to the base model. The turbo model also features a specialized red engine cover, exclusive radiator, and iridium plugs.

In response to the increased torque produced by the turbocharged engine, Mazda has reinforced the engine power transmission parts. The new model employs an upgraded clutch and transmission, reinforced drive and propeller shafts, torque-sensing LSD and specially designed muffler.

The new model features 205/40R17 80W tires and 17x7J aluminum wheels, exclusively tuned low-down suspension employing Bilstein dampers and silver-painted brake calipers.

Employs newly designed front, rear, and rear under spoilers, smoked headlamp bezels and ornaments designed especially for the Roadster Turbo.

- genuine leather-wrapped (with red stitched) steering wheel, shift knob and parking brake lever.
- Silver meter panel.
- Audio component including AM/FM electronic tuner and in-dash 6 disk CD changer.
- Metal tone center and shift panels.
