Hyundai Bayon review - MPG, CO2 and running costs

Mild hybrid tech means the Bayon should be cheap to run

The Hyundai Bayon is still very new and we don’t have complete data on its fuel economy or emissions yet - they’re all listed as TBC on the Hyundai website. However, it’s safe to assume that the Bayon will be cheap to run - after all, the only engines available at 1.0-litre petrols, which are pretty efficient and should be able to reach over 40mpg in normal driving.

This is also helped by the mild hybrid system in all models. This uses a 48v battery pack with a capacity of 1.56kWh along with a starter-generator. This set-up regains charge from the wheels as you slow down and uses it to give a small boost to the engine, mainly for efficiency. It’s nothing like a full hybrid or plug-in hybrid - it feels identical from behind the wheel to a non-hybrid car. It’s just good to know there’s modern tech at play to keep efficiency as high as possible.

Another bit of tech that helps with efficiency is the e-clutch that uses an electronic system to engage the clutch instead of a mechanical link. This helps to reduce wear and should mean the clutch lasts longer - though this won’t matter to new buyers unless they’re planning to keep the car for a long time.

Insurance groups

Entry-level automatic Bayons sit in group 13 for insurance, so while they’re not ultra-cheap considering it’s a 1.0-litre engine with under 100bhp, costs shouldn’t be too bad. The manual is actually in group 14, but that won’t affect premium prices too much.

Move up to a Premium model with the 118bhp engine and the insurance group rises to 16 with both gearboxes, and the top-spec car sits in group 18.


Residual values are pretty decent for the Bayon, with around 48-49 per cent of its value retained after a typical three-year/36,000-mile ownership period. Rivals such as the Ford Puma and Skoda Kamiq fare a little better, with figures of between 53-58 percent over the same period, depending on which model you opt for.
