Driven on the motorway, the Mito TwinAir settles into a steady 70mph cruise at 3000rpm. The engine offers flexible performance and NVH levels are very good; much has been done to the engine to ensure its smoothness including fitting a 'state-of-the-art flywheel', according to the Italian marque.
Opting between each of the car's driver settings (D, N and A) is no longer a guessing game of how the car has altered its personality. Flick the car into D and the Mito TwinAir's steering weights up instantly and the extra 6bhp and 30lb ft surge makes progress more sporting. The car's engine note also becomes raspier and louder, if a little intrusive into the cabin. N and A driving modes feel too restrained for motorway conditions and B-road blasts, being better suited to the city.
In D-mode and driven on twisty tarmac, the Mito turns in keenly, but does suffer from understeer when pushed; the Mito's front-end is some 10 per cent lighter than a four-pot equivalent Mito and this shows. Steering is also on the numb side and offers little driver feedback. That said, body roll is kept in check.
The six-speed gearbox doesn't inspire quick shifts (something you'll be doing lots of up hills) thanks to a soggy-feeling gear transition, not helped by the car's long gearstick.
Inside the TwinAir's cabin, the seating position is good thanks to plenty of adjustment to the seats and the steering wheel. Our test car came in Distinctive trim, plus optional tinsel including leather seats, an upgraded stereo and dual zone climate control.
Should I buy one?
Our test route involving mixed driving conditions (mainly motorway and B-roads in both D and N driving modes) revealed that you'll have to tread particularly carefully to achieve anywhere near the quoted 67.3mpg figure; in fact, 29.1mpg was our test car's verdict. Of course with a run-in engine (this one had only 700 miles down) and a light right foot, up to 40mpg should be achievable.
The Mito does, however, sound great, look good and is road tax and London Congestion Charge exempt. BIK, too, is just 10 per cent, some way better than its Audi A1, Mini and Citroen DS3 competitors at 13 per cent.
