Kia Niro MPG & CO2 emissions

The Kia Niro is more frugal than most diesel SUVs, but it's a long way off the standards set by plug-in hybrids

MPG (combined) MPG (extra high) MPG (medium) CO2
55.4-58.9mpg 62.8-68.9mpg 44.1-47.1mpg 86-99g/km

The Kia Niro isn't quite as impressive as the super-frugal Toyota Prius or Toyota Corolla, but thanks to its hybrid drivetrain, it’s still a cleaner and more efficient option than many diesel SUVs available today.

Kia Niro MPG

Efficiency – as expressed in official figures at least – is dependent on alloy-wheel size, with the 2 claiming 58.9mpg and the 3 and 4 models managing 55.4mpg. The good news is that our colleagues at Auto Express managed to get around 60mpg out of a pre-facelift Niro hybrid (which used the same powertrain), so it's likely that you'll manage to match or even better the official figures in real-world use.

Although the Niro has an electric-only driving mode that works up to speeds of 70mph, the small batteries mean you can only cover a maximum of three miles like this, even if driving very gently. So, unlike owners of the plug-in Niro, you don’t have the prospect of petrol-free, zero-emissions daily commuting.

CO2 emissions

The Niro's CO2 levels are quite dependent on wheel size, too, and while at 86 to 99g/km they do bring fairly low company-car and road tax, they're not as good as on some rivals.
