Mazda has revealed its all-new Mazda 3 Fastback, a saloon version of its upcoming hatchback.
The Fastback will be offered with a choice of one of three naturally aspirated petrol engines or one turbocharged diesel engine, all of which are fitted as standard with a start-stop system.
The entry-level 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.
