Mazda isn't afraid to do things differently - as the RX-8 proves. It breaks traditional coupe convention by having two rear-hinged doors to make access to the back easier plus it's powered by a unique rotary engine.

Running costs

The Mazda is well priced but depreciation is only average and it doesn't hold it's value as well as the Nissan 350Z. The biggest cost owners will face is fuel - the claimed economy figure is around 26mpg, while tax and insurance will also be high. Mazda servicing is reasonable though and the dealers have an ever-improving reputation.

There's no getting away from the fact that the RX-8 is a polluting model. The high output model emits 284g/km of CO2 while the less powerful variant is little better, putting out 267g/km. Both models are very thirsty too - averaging around 26mpg. The R3 has a tweaked engine - but emissions are 299g/km of CO2 and economy has dipped slightly to 24mpg.
