Performance
The 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 189bhp or 228bhp
depending on the state of tune. 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 of 654cc
each. There's a subtly menacing
whirring noise, while power delivery is
progressive, instantly accessible and
builds rapidly in intensity. A snappy sixspeed
manual gearbox and the fact that
the rev counter's needle zips so swiftly
round the dial means that a relative lack
of torque rarely intrudes.
Driving
One of the main benefits of the Renesis
engine is its incredibly compact size. It
allowed Mazda's engineers to position
it very close to the centre of the car,
giving the RX-8 a mid-engined layout
and perfect 50/50 weight distribution.
What this means in practice is wellbalanced
handling with little understeer.
The RX-8 attacks corners with relish;
feeling taut and controlled, and giving
you the confidence to make the most of
that rev-happy engine.
Space
The RX-8 has what Mazda terms a
'Freestyle' door mechanism. Behind each
front door is a secondary mini-door,
with no external door handle. To give
good strength in a side-on crash, the
front doors overlap. The latter hinge
backwards to open, leaving a pillarless
hole to allow a pair of rear passengers
to gain easy access. They'll find similar
space in there to a BMW 3-Series Coupe.
Build quality
The interior is suitably performance-oriented,
with a high transmission tunnel
running between the front and rear
sports seats. The dashboard is a bit
plasticky, but it's nicely laid out and has
a quality feel. So far the Renesis rotary
engine has been reliable, but it's a high
performance unit so who knows what
will happen to it over time.
Safety
The Mazda RX-8 is fitted with six
airbags (front, side and curtain) as
standard as are both traction and
stability controls.
Owning
Poor fuel economy (25mpg) and the car
being in the top 35 percent company car
tax bracket means it's not cheap to run.
Value
Costing between £21,400 and £23k
the RX-8 is great value for money,
undercutting many of its rivals. But
prices are coming down and there are
discounts available through dealers.
Verdict
Sharp, fast and different, the Mazda RX-8 still stands out from the
coupe crowd. Yet despite its futuristic appearance, it boasts a roomy
interior and is very affordable at the same time, making it a great
hot hatch alternative.
