Mazda unveiled the RX-8 at the 2001 Tokyo Motor Show.
Mazda exhibited the RX-EVOLV at 1999 Tokio Motor Show, as a proposal for a replacement sports automobile with Associate in Nursing innovative packaging conception supported the next-generation rotary engine. Mazda received a positive response for the conception automobile from customers everywhere the planet. At the 2001 North yank International automotive vehicle Show, Mazda additionally exhibited a style and engineering model of the RX-8, that was a results of our company want to understand the potential that the RX-EVOLV showed.
In developing the RX-8, Mazda strove to understand conflicting goals: delivering a vehicle with placing, jazzy styling with a superior mix of handling and performance, whereas providing ride comfort and therefore the practicality for four adults. A key think about achieving these goals is that the RENESIS engine, the next-generation rotary powerplant, that is additional compact and higher-powered than previous rotary engines, that includes a water cooled, two-rotor configuration. This delivers a most output of 184kW/8500rpm and 216Nm of torsion at 7500rpm, whereas achieving improved fuel potency and cleaner emissions. The RX-8 incorporates each real sports automobile styling and an internal package spacious enough for four adults. It additionally includes an extra refined front-midship layout likewise as a race, four-door configuration while not a middle pillar. Exceptional driving performance comes through 50:50 front/rear weight distribution and little yaw-inertia moment. With superior usefulness, the RX-8 can meet the expectations of a wider vary of shoppers, not solely sports automobile fans.
The RX-8 is a wholly new sports automobile embodying Mazda’s “Zoom-Zoom” whole message to the most, by following “Distinctive style,” “Exceptional practicality,” and “Responsive handling and performance.”
Unprecedented Sports automobile Styling Encapsulating house for Four Adults
The form of a real sports classic Mazda has created several sports cars with exciting styling that stand the take a look at of your time, like the first-generation Cosmo Sport, the RX-7 and therefore the MX-5/Miata/Roadster. Following this tradition, Mazda designers were determined to grant the four-door, four-seater RX-8 unexampled styling. They began by sculpting a body with a dynamic feeling of motion. Exciting surfaces run from the aggressive front air intake on the body to the lid. The classic rear-wheel drive sports layout places visual stress on the rear tires. Short front and rear overhangs, and characteristic overfenders, underline the vehicle’s look of stability. The styling could be a classic statement of beauty in motion, harking back to a prime contestant.
This is the right embodiment of Mazda’s new style philosophy of “Emotion in Motion.” The adoption of the race door system, for four doors while not center pillar, means that the RX-8 is Associate in Nursing unexampled combination – the planning and feel of a real sports automobile in a very four-door vehicle. the form of the rear pillars and car window pay court to the first-generation Cosmo Sport and RX-7, however its innovative package provides enough house for four adults.
Low, dynamic forepart Aggressive lines extending from the air intake on the low hood that solely a rotary engine with its compact style will create possible; an influence bulge within the center of the hood with a rotor because the motif; a bumper facia accentuation the “cubic” effect; and short front overhang all mix to form a dynamic sports automobile image and emotional atmosphere, enhancing the car’s Zoom-Zoom spirit. additionally, the front fender wheel arches stand high and further from the low hood to visually manifest the RX-8’s power and supply the driving force a transparent read of the front corners of the vehicle.
Rear read with emotional and funky styling cues The rear read is intended to form a vivid impression because the automobile drives away – a vital thought for a sports automobile. this can be partially achieved by the RX-8’s short rear overhang. Rear combination lamps receive a mechanical bit through the addition of chrome accents, a rotor-shaped rear fog lamp is found low within the center of the bumper, and therefore the twin exhaust pipes square measure placed to the left and right. Taken along, these components produce a sway that’s at the same time emotional and modern.
RESPONSIVE HANDLING AND PERFORMANCE
High-mount backbone frame to grant the RX-8 the rigidity a real sports automobile demands, a strong, high-mount backbone is found within the higher a part of the transmission tunnel. This backbone runs from the front partition through the cabin to the rear partition and functions because the main frame of the chassis, enhancing rigidity and permitting reduction of body-panel thickness and weight. It additionally contributes to safety within the event of a collision.
Closed-section station frame (PPF) The light-weight closed-section PPF locks the complete powertrain – as well as the pinion and crown wheel – into one rigid unit. This mechanism enhances direct and linear acceleration feel and crisp shift operation with many sports automobile driving pleasure.
One-piece, carbon-fiber propellor shaft Even with a two,700mm distance, the RX-8’s front-midship layout drastically shortens the space from the gear case to the differential. This allowed engineers to put in a one-piece propellor shaft product of carbon fiber, that additional reduced weight.
Double-wishbone suspension at front and multi-link beam suspension at rear Long-arm double-wishbone suspension at the front and multi-link beam suspension at the rear give ideal suspension pure mathematics. Long arms and links win suspension dimensionality and roll management, whereas optimum roll-center height maximizes suspension stroke. Tires stay perpendicular to the road throughout the length of suspension travel for superior grip, even underneath the toughest cornering. The result’s excellent roadholding with no sacrifice in ride comfort. because of the greatly reduced yaw-inertia moment (a results of the front-midship layout), optimum roll-center height and tire camber management, the RX-8 delivers a pointy response to steering inputs and increased controllability. This chassis and suspension style additionally allowed the adoption of large-diameter 18-inch metal wheels with high-grip 225/45ZR18 tires. Rack-and-pinion power-assisted steering offers correct feedback on road conditions, whereas an electrical power-steering pump delivers exactly the proper quantity of assist to match driving conditions. One additional advantage of an electrical power-steering pump is improved fuel economy, as electrically driven steering, as critical the standard belt-driven system, doesn’t drain power from the engine. Large, 17-inch aerated discs on all wheels offer positive, positive braking in support of safe, jazzy driving. Six-point rubber mounts on the rear subframe improve each driving stability and road noise.
GREATER SAFETY AND thought FOR THE surroundings
Improved performance to side-collisions putting the RENESIS engine front midship accomplished a sufficiently giant crushable zone between the engine and front bumper. This ensures improved impact absorption in head-on and offset frontal collisions. At identical time, the RX-8 additionally provides superior performance in side-impacts. it’s a extremely rigid anatomical structure for a sports automobile, in spite of the pillar-less, wide-opening style. to attain this, an oversized range of measures were adopted as well as a rigid stomach frame, the high-mount backbone running through the cabin, and thoroughly planned chassis reinforcements. A reinforcement structure forms a virtual center pillar designed into the door frames, whereas prime and bottom latches lock the rear door to the body. additionally, a security lock mechanism permits the rear doors to open on condition that the front doors square measure open, too. Active-safety measures embody large-diameter 17-inch aerated disc brakes on every wheel, a 4W-ABS (four-wheel anti-lock braking system), and freshly adopted DSC (dynamic stability control) that senses once the vehicle begins to skid or spin, and counters it by dominant engine torsion and applying the brakes as required.
Tackling surroundings issues Zero overlap between the intake and exhaust ports leads to increased thermal potency for the RENESIS engine, permitting a way throw air/fuel mixture for fuel potency once inactivity compared to the 13B-REW rotary engine within the RX-7. additionally, because of the potency inherent within the rotary engine, the RX-8 operates with a lean mixture even throughout high-speed high-load operation. A high compression magnitude relation and freshly developed ultra-fine fuel injectors create just about good combustion potential across the engine’s entire speed vary. Rotary engines even have structural qualities that cause them to come up with less Roman deity (nitrogen oxide) than typical engines. RENESIS’ side-exhaust layout retains turn HC (hydrocarbons) for following combustion cycle, additional lowering emissions. additionally, a freshly developed convertor for the rotary engine is teamed with a double-skin manifold that maintains a high exhaust-gas temperature to boost catalyst activation on engine begin, even in cold conditions.
