Hyundai Bayon

Hyundai Bayon at a glance

Origins and the i20 connection

Hyundai presented the Bayon in March 2021 as a crossover version of the third-generation i20, replacing the i20 Active in spirit. It has no all-wheel drive and shares its mechanical base with the hatchback. Hyundai placed the Bayon below the Kona, so it is the brand's smallest European SUV.

Autonotizen.de drove the Bayon in April 2021 and noted that versions without the mild-hybrid system have a 411-litre boot, because the lithium-ion battery of the 48-volt cars sits under the floor.

Engines and performance

The first four lines are pre-facelift data from Wikipedia; the 1.4 MPi is not part of the European range. With the DCT the 1.0 T-GDi 100 needs 11.7 seconds and reaches 181 km/h. Since November 2025 ADAC lists only the 66 kW (90 PS) 1.0 T-GDI in Germany, with a WLTP consumption of 5.8 l/100 km and 131 g/km of CO2 for the manual version.

Gearboxes and the 48-volt system

The Bayon has an unusually wide choice of transmissions for a small car. Wikipedia lists five- and six-speed manuals, a six-speed clutchless manual (Hyundai's iMT, where the clutch is operated electronically), a six-speed torque-converter automatic for the 1.4 MPi and a seven-speed dual-clutch gearbox (DCT).

The 1.0 T-GDi with 74 or 88 kW was sold as a mild hybrid. Its small lithium-ion battery sits under the boot floor, which costs some luggage space: Autonotizen.de gives 411 litres only for the versions without this system. The facelifted 66 kW engine listed by ADAC since November 2025 produces the same 172 Nm as the earlier 74 kW mild hybrid.

The 2024 facelift

Hyundai revealed the facelift on 18 January 2024. Changes include:

• a new LED daytime running light across the full width of the front;
• a redesigned front fascia and new bumpers at both ends;
• new alloy wheel designs;
• more interior and safety equipment.

Wikipedia also reports that a second-generation Bayon is to be unveiled in India.

Dimensions and practicality

Folding the rear seat adds 794 litres of luggage space. The 2,580 mm wheelbase is the same as that of the Kia Stonic. With a 40-litre tank and 5.8 l/100 km WLTP, the 1.0 T-GDI 90 has a theoretical range of about 690 km.

Bayon compared with the Kia Stonic

The Bayon and the Kia Stonic come from the same group and use the same 1.0 T-GDI engine family. ADAC data of the 2025 facelifts allow a direct comparison.

• The Bayon is 15 mm longer and has 59 l more boot space than the Stonic.
• The Stonic has 8 kW more and is 0.9 seconds quicker to 100 km/h, for €110 less in the late-2025 ADAC lists.
• Weight per kW: 17.8 kg per kW for the Bayon (1,175 kg and 66 kW) and 16.3 kg per kW for the Stonic (1,205 kg and 74 kW).

Safety

Euro NCAP tested a Bayon 1.0 T-GDi in 2021. It scored 76 percent for adult occupants, 82 percent for children, 76 percent for pedestrians and 67 percent for safety assistance. The star rating is not given in the sources used here.

Sales

Hyundai sold 15,404 Bayons in Europe in 2021, 20,486 in 2022, 27,793 in 2023 and 28,241 in 2024. Turkey added between 5,067 and 17,581 per year in the same period. By our calculation that is 91,924 European sales in the first four years.

Prices in Germany

The gap between the cheapest and the dearest Bayon in the November 2025 list is €6,700. All current German versions use the same 66 kW engine; trim and gearbox make the difference.
