Hyundai Bayon SUV - MPG, running costs & CO2

Like the Hyundai i20, the Bayon is fitted with a 1.0-litre petrol engine fitted with 48-volt mild-hybrid technology. This recovers some energy while the car is decelerating, storing it in a small battery and boosting the engine's pulling power when setting off. It can also help its engine switch off more effectively in traffic or when stopped at a red light. The engine can cut off from 15mph or so, letting you coast to a stop on electric power.

Hyundai Bayon MPG & CO2

Both 99bhp and 118bhp versions of the 1.0-litre engine are available, with CO2 emissions of 118-120g/km. This places the Bayon in a middling Benefit-in-Kind (BiK) for company-car drivers. It also slightly undercuts the 129g/km of the 1.0-litre petrol SEAT Arona.

Whichever version you pick, you can expect up to 53.3mpg, broadly matching the class leaders. The Bayon should be inexpensive to run, although we couldn’t match that figure on our (admittedly short) test drive.

Insurance groups

Insurance should be affordable, with key 1.0-litre rivals hovering around group 10 out of 50 - around the same as most superminis. Hyundai also tends to offer affordable servicing, with plans available upfront to help spread the cost of maintenance over monthly payments. Check out our guide to the best cheap cars to insure.

Warranty

Hyundai provides a desirable five-year/100,000 mile warranty that's more generous than the three years of no-cost cover provided by Skoda and Ford. However, Kia offers a seven-year warranty and Toyota buyers can now enjoy up to 10 years of cover, as long as they have their cars maintained by a Toyota dealer. 

Servicing

Like most mainstream manufacturers, Hyundai now offers fixed-price servicing plans that are well worth considering. These help spread the cost of prescribed maintenance out over monthly instalments. They can also be purchased up front, making the cost of running the Bayon more predictable.
