2020 Kia Stonic mild-hybrid: engines, specification and release date

Kia has updated its Stonic 'crossover', with a brand-new mild-hybrid engine option, which goes on sale later in 2020

The Kia Stonic crossover - essentially a high-riding, SUV-style hatchback - has been given a mid-life refresh for 2020, and one of the biggest changes made is the addition of a new petrol-electric mild-hybrid engine for greater fuel economy.

Unlike other hybrid small SUVs like the Renault Captur plug-in hybrid and the conventional Hyundai Kona Hybrid, the Kia Stonic mild-hybrid can’t cover any miles under electric power alone. Instead, the Stonic’s small 48V battery and starter-generator unit are there to give the car’s 1.0-litre turbocharged petrol engine a bit of a helping hand under acceleration.

This, by extension, helps improve the Stonic’s fuel economy - though it’s not clear yet by how much, as Kia hasn’t announced the official fuel economy figures yet. Likewise, prices and specifications for the facelifted Stonic will be revealed closer to launch, though we do know Kia will introduce new safety equipment, an updated touchscreen media system and some extra customisation options as part of the update.

There’s more to the revised Kia Stonic’s engine range than just the mild-hybrid system, though. Another new engine that’s joining the line-up is an entry-level 1.2-litre petrol, and there’ll also be a 1.0-litre turbocharged petrol option that goes without the mild-hybrid tech - meaning a lower price and lower fuel economy.

Quick facts

  • Total power up to 120hp in mild-hybrid
  • Manual and automatic gearbox options
  • Prices and fuel economy to be confirmed
  • Joins range as part of mid-life facelift
  • Other updates include new safety assists
  • Goes on sale in late 2020

2020 Kia Stonic mild-hybrid: engines and performance

Being a mild-hybrid model, the petrol-electric Kia Stonic doesn’t have any electric-only range statistics to its name. Instead, the small starter-generator and the 48V battery pack that powers it are there to reduce the stress on the car’s 1.0-litre turbocharged three-cylinder petrol engine, and therefore improve its CO2 emissions and fuel consumption.

How much more frugal this mild-hybrid version will be over other Stonics remains to be seen, as Kia hasn’t revealed any fuel economy figures yet. It has, though, confirmed the hybrid Stonic will be available in 100hp and 120hp incarnations, and the gearbox options will consist of a six-speed manual and a seven-speed automatic.

In addition to the mild-hybrid option, Kia has given the Stonic’s range of conventional petrol engines a bit of a refresh. New to the range is a 1.0-litre turbocharged three-cylinder with 100hp, which will come with six-speed manual and seven-speed automatic gearbox options, and there’ll also be an 84hp 1.2-litre four-cylinder petrol that will likely only be available with a five-speed manual.

Whether the current car’s 1.6-litre 115hp diesel engine will be retained isn’t known yet, as Kia hasn’t confirmed whether or not it will be carried over into the facelifted Stonic.

2020 Kia Stonic mild-hybrid: specifications and in-car tech

While the mild-hybrid engine is the big new addition to the Kia Stonic, this isn’t the only update added as part of the facelift. The interior has also been given a bit of a once-over, to make the car feel more up to date.

One of the most significant new additions is the new eight-inch touchscreen display that replaces the pre-update car’s seven-inch screen - and, like before, you can connect your smartphone to it using Android Auto and Apple CarPlay.

A slew of safety aids and driver assists are also coming to the updated Kia Stonic, ranging from features like adaptive cruise control to monitoring systems that alert the driver if there’s another vehicle hidden in one of the Stonic’s blind spots. Exact safety features will be confirmed when the full UK specifications are revealed nearer the launch date.

2020 Kia Stonic mild-hybrid customisation options

The Kia Stonic already comes with a decent range of paint options, and the facelifted model has even more colours for buyers to choose from. Two new hues - a 'Storm Grey' dark grey and an 'Azure Blue' navy shade - have been added to the colour chart.

Also new for the updated Stonic is an extra two-tone paint option in the form of a bright 'Zest Yellow' finish for the Kia Stonic’s roof.

2020 Kia Stonic mild-hybrid prices and delivery dates

The Kia Stonic mild-hybrid and the rest of the updated Stonic range will go on sale later in 2020. Delivery dates haven’t been confirmed just yet, though it’s expected the first facelifted Stonics will arrive in the UK before the end of 2020.
