Not only is the Toyota iQ relatively expensive to buy even in base spec form, but it’s also likely to prove nothing like as cheap to run as the raw data suggests. Believe the official claims and you’ll think fantastic fuel economy is possible (especially with the 1.0 litre car) in restrained but hardly saintly driving. It’s not.

We had two all but identical iQs at the same time, and even when driven in no great haste and in favourable conditions, neither managed to stretch a gallon of unleaded even 50, let alone 60 miles. We averaged a disappointing 35.2mpg, which didn’t even allow us to cover 250 miles before filling up.

Oddly enough for such a car, the iQ1 & 2 lack the stop-start technology that’s starting to pop up on a wide range of small cars, not least its Smart ForTwo rival. Better news is that unless you opt for the 1.3 or the CVT auto (and we wouldn't, having tried it), the iQ’s tax disc will be free and it will be assessed for company car tax based on a low benefit in kind .

The iQ3, powered by the 1.33 engine, officially returns marginally worse economy, and substantially worse CO2 emissions, not least because of the VED road tax the rise attracts.
