The turbocharged, 875cc, two-pot engine has a power output of 84bhp. Alfa Romeo claims that the TwinAir-powered Mito will achieve a combined fuel economy of 67.3mpg, with 98g/km of CO2.
Performance figures are a claimed 12.5sec to 62mph from standing, with a 108mph top speed.
Despite the initial purchase premium over the £12,500 1.4-litre 8v base model, the new Mito variant is road tax and London Congestion Charge exempt, saving buyers ‘up to £2500 per year’, according to the Italian firm's figures.
Two trim levels are offered on the Mito TwinAir – Sprint and Distinctive (priced at £15,130) - the latter of which features 17-inch sports alloys, chrome touches to the car’s exterior, and red brake callipers.
