Fuel economy

A more stringent standard for fuel economy (WLTP) was introduced from September 2017, and this model was not required to undergo that test. Its fuel economy measured under the previous test system was 44 - 51 mpg. However these figures are less likely to be achievable in real world driving and so should never be compared to another car's mpg which was measured under the newer, more realistic WLTP system.

Reasonably well-spaced service intervals, engines deliver above-average fuel economy, good insurance groupings (except Rally 2 and Rally 4).

Sirion performs very well on the eco front. With an average of 142 g/km CO2 across the model line-up, its emissions are comparably low for a super mini hatchback. It’s worth noting that the line-up does not feature any diesel models, which typically produce less carbon dioxide than petrol engines with similar power outputs. Eco-conscious buyers should consider the 1.0-litre petrol, which is one of the greenest models in the range.

The range is impressively frugal, averaging 47 mpg.
