Toyota Corolla MPG & CO2 emissions

Although not a match for its plug-in hybrid rivals, the Toyota Corolla's MPG and CO2 figures are competitive

The claimed fuel economy and official CO2 emissions figures for the Toyota Corolla hatchback vary considerably, depending on whether you go for the 1.8 or 2.0-litre hybrid powertrain, and exactly what size of alloy wheel you specify. CO2 emissions run from 76 to 89g/km and economy ranges from 50 to just under 63mpg, which is broadly competitive with hybrid rivals such as the Hyundai Ioniq Hybrid (63mpg) and Kia Niro (60mpg).

Toyota Corolla MPG & CO2 emissions

The most efficient Corolla hatchback is the 1.8-litre on 16-inch wheels, which emits 76g/km of CO2 and returned nearly 66mpg under the WLTP testing procedure. Increasing the wheel size to 17 or 18 inches ups the emissions to 83g/km, while the 2.0-litre hybrid engine (which is only available with the larger wheels) emits 89g/km of CO2 and will return just over 50mpg economy.

The Corolla will make the most difference to your running costs if you regularly tackle low-speed, stop-start urban driving. This gives the car's hybrid drivetrain the greatest opportunity to run in electric mode, with Toyota claiming that up to 50% of a typical commute can be covered on battery power. For those who do more long-distance motorway runs, however, a modern diesel may make more financial sense.
