Fuel consumption and CO2 emissions for the Toyota Auris are broadly in line with the class average, although our recorded fuel use was significantly less than the claimed figures.

The 1.33-litre model is the cheapest to run, but it’s likely you’ll not see the claimed 48.7mpg if you spend much time on the motorway, such is the strained nature of the engine. CO2 emissions of 136g/km aren’t that hot either – the Honda Civic 1.4 achieves a 129g/km rating.

It's cheaper than a less well-equipped Golf

The Civic’s 1.8-litre petrol engine outperforms the Auris’ 1.6-litre unit too. The Toyota achieves a rating of between 146g/km and 154g/km, depending on trim and gearbox. The Civic emits just 143g/km. The Honda betters the Toyota’s fuel consumption figures too, with Auris returning a claimed 42.8mpg with a manual gearbox and 44.8mpg with the MultiMode automatic.

The diesel is the champion for running costs, hybrid aside. The 1.4 diesel records a claimed combined figure of 58.9mpg, or 57.6mph with the self-shifter. While competitive, neither figure is exceptional – there are plenty of diesel engines of a larger capacity and with more power that can achieve these figures. Emissions are rated at 128 and 130g/km for the manual and automatic respectively.

Toyota’s hybrid version offers the most compelling on-paper running costs, even if it costs around £2000 more to buy than the next most expensive model in the range. Its emissions of 89g/km when fitted with 15-inch wheels and 93g/km on 17s mean it is exempt from both road tax and the London Congestion Charge.

Officially, the Auris Hybrid is capable of 74.3mpg on 15-inch wheels or 70.6mph on 17s, but it takes patience and skill to record more than 50mpg. If your journey involves winding lanes, or high speed roads, it’s likely to achieve economy in the mid-40s.
