The 2011 Mazda RX-8 uses the latest generation of Mazda's Renesis twin rotary engine with a combined displacement of 1.3 litres. It doesn't rely on turbo-charging, yet manages to produce 228bhp. Instead of a succession of cylinders and pistons there's a large oval chamber in which a roughly triangular 'rotor' rotates. Where the faces of the triangle pass the spherical sides of the chamber, three separate crescent-shaped spaces are formed. Within these, the stages of the combustion process - induction, compression, ignition, combustion and exhaust - all occur as each pass the inlet ports, twin spark plugs and exhaust ports. There are two of these chambers, each with a nominal capacity o 654cc each. There's a subtly menacing whirring noise, while power delivery is progressive, instantly accessible and builds rapidly in intensity.

The Mazda RX-8 was designed as a front mid-engine, rear-wheel drive four-seat four-door coupé. The car has 52:48 front-rear weight distribution, and a low Polar Moment that is achieved by mounting the engine behind the front axle and the fuel tank ahead of the rear axle. The front wheels feature classic independent double wishbone suspension, while the rear are independent multi-link. Weight is trimmed through the use of materials such as aluminium and plastic for several body panels. The rest of the body is steel, save for the plastic front and rear bumpers. The manual gearbox model uses a carbon fiber composite driveshaft to reduce the rotational mass (moment of inertia) connected to the engine. Power is sent to the rear wheels via a Torsen limited slip differential for improved handling. While its not quite in the league as the last Mazda RX-7 in terms of raw performance, the Mazda RX-8 is considered its successor as Mazda's rotary engine sports car. Its layout and clever engineering, along with typical Mazda suspension tuning, have endowed it with excellent driving dynamics which have garnered much praise and numerous awards. It has also proven popular in Japan among car enthusiasts as well as aftermarket equipment manufacturers and professional tuners.

Mazda engineers improved the 2011 Mazda RX-8 body rigidity through the addition of structural reinforcements, by adding a trapezoidal strut tower bar and enhancing the local rigidity of the front suspension tower areas. The 2011 Mazda RX-8 is also 90 lbs lighter than the previous (2011-2012) models. Additionally, the rear suspension geometry has been reconfigured for better handling by improving driveshaft rigidity, lowering NVH levels, and improving overall performance. The 09 RX-8 has a different gearing ratio (on manual transmission-equipped cars) that is lowered from 4.444 to 4.777 for improved off-the-line performance. While minimal, these performance changes give the 2011 Mazda RX-8 increased acceleration and performance, as well as even greater responsiveness to the accelerator pedal. Mazda claims that the 09 RX-8 is a significantly faster car than the previous (2011–2012) model car due to the lighter weight, lowered gearing, and improved suspension.

The 2009 Mazda RX-8 also receives design enhancements that are meant to freshen the styling and give the RX-8 a new look, without impairing the basic design theme. Refinements for the 2009 model year include a more aggressive restyled front and rear bumper as well as a new front fascia. The 09 RX-8 also comes with sporty, high-quality finish front and rear headlamps as well as larger exhaust pipes (now measuring 90 mm across). The 2009 Mazda RX-8 also offers a new five-spoke wheel design featuring a symbolic and sporty design reminiscent of the rotary engine, with different arrangements for each wheel size.
