engine, a 99bhp 1.5-litre petrol, is a brand-new unit that's claimed to
be capable of averaging 56.4mpg when specified with a six-speed manual
gearbox. Its emissions are rated at 118g/km of CO2, ensuring relatively
low road tax.
More powerful 2.0-litre 118bhp and 162bhp petrol
engines will also be available. The 118bhp engine averages 55.3mpg, and
emits 119g/km of CO2, in conjunction with a manual transmission; the
162bhp unit is rated at 48.7mpg and 135g/km of CO2.
Those seeking maximum economy will no doubt be tempted by the 148bhp 2.2-litre diesel, which Mazda claims to be capable of 72.4mpg. Its emissions are stated to be an equally thrifty 104g/km of CO2.

hatchback. it does, however, share the same 2700mm wheelbase as the
To further improve practicality the saloon gets a wider
boot opening, allowing luggage to be loaded and unloaded more easily. It
also retains the same folding rear seat arrangement as its five-door
sibling, allowing for more storage space when needed.
Like the hatchback, the Fastback benefits from Mazda's
SkyActiv range of technologies, which aim to reduce weight and improve
efficiency. Kerb weights for the Fastback are claimed to start at as
little as 1196kg, while the hatchback weighs in at 1200kg.

of 0.258, which is lower than that of the sleek Chevrolet Volt.
