Mazda RX-8 Original Generation Sport Prestige Limited Twin-Rotor Engine

Engine identity and application

The Sport Prestige Limited went on sale in Japan on 24 November 2004. Mazda offered a Type S-based six-speed manual and a Type E-based four-speed Activematic automatic. Its Japanese announcement lists a water-cooled twin-rotor engine for both. Mazda’s special-edition announcement.

This record covers those two applications together beneath the special-edition variant. Their shared engine architecture does not imply identical output.

Design and engineering

RENESIS used two rotors of 654 cc each, giving a nominal combined displacement of 1,308 cc. It was naturally aspirated, with side exhaust ports and a Sequential Dynamic Air Intake System. Mazda developed these features to combine rotary performance with improved fuel economy and emissions relative to earlier rotary engines. RENESIS production announcement.

The RX-8 also used side intake ports and electronic throttle control. The compact engine supported a front-midship layout, with its principal mass behind the front-wheel centre line, helping package a four-door, four-seat sports car. These were characteristics of the underlying RX-8, rather than developments unique to this edition. RX-8 engineering description.

Transmission-dependent specifications

The edition announcement establishes the Type S/6MT and Type E/4AT pairings but does not repeat power, torque or engine-speed figures. Mazda’s April 2003 Japanese base-grade specifications provide the following context:

Japanese base grade	Transmission	Maximum power	Maximum torque
Type S	Six-speed manual	184 kW (250 PS) at 8,500 rpm	216 N·m at 5,500 rpm
Type E	Four-speed Activematic automatic	154 kW (210 PS) at 7,200 rpm	222 N·m at 5,000 rpm

These are dated base-grade figures, not a separately published November 2004 special-edition test result. PS denotes metric horsepower. Mazda’s Japanese-market launch specification.

The special-edition release describes equipment, suspension and body-rigidity changes without announcing an engine-output increase. Its common engine description should therefore not be used to assign the Type S rating to the automatic. Edition equipment and powertrain table.

Manufacturing and chronology

RENESIS engine production began at Mazda’s Ujina plant in Hiroshima, Japan, on 29 January 2003. That establishes the engine family’s manufacturing origin, rather than the assembly-start date of this later special edition. Mazda’s manufacturing announcement.

The Sport Prestige Limited’s 24 November 2004 date is its Japanese sales launch. The cited edition announcement gives no exact production-start date, production-end date or engine total. It does not establish a worldwide model-year designation. Japanese launch announcement.

Place in the RX-8 range

The edition illustrates how Mazda combined its established rotary powertrain choices with a more luxurious interior and revised chassis. Its historical interest lies in this refinement of the early RX-8; the announcement does not identify a new engine family. Mazda’s edition description.

See the parent Sport Prestige Limited record for vehicle equipment and the original-generation overview for wider chronology. The Sport Prestige Limited II twin-rotor record covers a separately catalogued edition whose specifications should be consulted independently.
