Low figures relate to the least economical version; high to the most economical. Based on WLTP combined fuel economy for versions of this car made since September 2017 only, and typical current fuel or electricity costs.

Peugeot 108 running costs are pretty good if we go by the official consumption figures but buyers are restricted when it comes to choice.

No diesel engine is offered and there are only two petrol engines: a 1.0-litre option for those who choose the Access and Active trims and a 1.2-litre for Allure and Feline trims.

The 1.0-litre engine when accompanied by stop/start technology has an impressive official fuel economy figure of 74.3mpg. Without the technology fuel economy drops slightly to 68.9mpg. If you opt for the automatic gearbox then fuel economy slightly dips again to 67.3mpg.

The higher-powered 1.2-litre petrol engine offers an official fuel consumption figure of 65.7mpg which is only slightly lower than the fuel economy offered in the 1.0-litre option - not bad considering the 1.2-litre offers 14bhp more.

Like all official consumption figures, they are to be used as a benchmark to compare different cars amongst one another rather than representative of real world driving.

Peugeot 108 emissions are pretty good across the range with no car emitting over 100g/km of carbon dioxide.

The lowest-emitting car is the 1.0-litre petrol engine with Stop/start technology which has CO2 emissions of 88g/km. The 1.0-litre petrol when accompanied by an automatic gearbox has emissions of 97g/km while the 1.0-litre petrol without stop/start emits only 95g/km.

The 1.2-litre petrol has the highest emissions of the range but still manages to still slip under the 100g/km threshold at 99g/km.

Peugeot doesn’t expect to sell many 108s to the fleet market with a 80:20 share forecasted in favour of private sales, however thanks to the low emissions and a competitive list price, company car tax bills will be kept pretty low for those who do consider it.

We expect the Peugeot 108 reliability to be good as the French manufacturer has a proven track record of producing reliable cars. We rarely hear of Peugeot cars being recalled so we can see no reason why the new 108 will not continue this trend.

The 1.2-litre petrol engine has been previously seen in the 208 and is also available in the award-winning 308 and 3008 cars. The 1.0-litre engine is a Toyota engine which we also think should be problem free – that firm has an enviable reliability record.
