What are the running costs?

There’s no full hybrid – plug-in or regular – here; neither is there an electric variant like the Vauxhall Mokka-e or Peugeot e-2008.

Instead, there’s a 1.0-litre turbocharged petrol three-cylinder with either 100- or 120hp – the latter of which has 48-volt mild-hybrid assistance. There’s no diesel option, either, but the turbocharged engines get the choice of a six-speed manual or a seven-speed automatic gearbox.

The mild-hybrid model comes with a so-called ‘intelligent’ six-speed manual. This means that the 120hp model can start and stop its engine very quickly and smoothly, even when you’re coasting along at speed in gear. This is because the clutch pedal is controlled electronically rather than by a mechanical linkage, though some might find this set-up means it’s harder to judge the biting point when setting off or changing gear.

Nearly every version of the Bayon has the same quoted WLTP fuel economy figure of 53.3mpg. The only exception is the 120hp manual in top-spec trim, which returns a barely different 52.3mpg. Emissions figures range from 119-121g/km. These figures are competitive.

Servicing and warranty

Hyundai’s cars have been made more desirable thanks to their improved quality and tech in recent years, but the firm’s five-year warranty remains just as attractive as it has ever been. While sister firm Kia can beat this length of cover by another two years, Hyundai’s warranty has an unlimited mileage cap, which will be attractive to high-mileage drivers.

Servicing is annually, and Hyundai offers a variety of service plans for the Bayon. These can be paid for up front or monthly, and can also be bundled in with any finance package you might take out. Get your car serviced at a Hyundai dealer, and the Bayon’s initial 12 months of roadside assistance will be renewed for another 12 months.

Reliability

Since the Bayon is based on the Hyundai i20 – and even uses the same dashboard and technology – you can expect it to be a reliable machine. Hyundai doesn’t offer a five-year warranty for no good reason, it shows it has confidence in its products, and the reality is that you’re unlikely to ever need it.
