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

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

Kia Niro MPG

Efficiency – as expressed in official figures at least – is dependent on alloy-wheel size. Even the best figure lags well behind the Toyota Prius’ best claim. 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 even if driving very gently. So, unlike the plug-in, you don’t have the prospect of petrol-free daily commuting.

CO2 emissions

CO2 levels are quite dependent on wheel size, too. Again, the Toyota Prius puts in a stronger performance.
