Hyundai Motor unveiled the company's first electric double-decker bus, which has a 186-mile driving range on a single charge.

To develop the company’s first electric double-decker bus, Hyundai worked for 18 months on a project supported by the Korean Ministry of Land, Infrastructure, and Transport, which began in 2017.

The bus allows up to 70 passengers ― 11 seats on the first floor and 59 seats on the second floor ― 1.5 times as many passengers as compared to that of a regular bus.

Through the implementation of two fixed-in-space wheelchairs, an automatic sliding ramp and low-floor design, the double-decker bus secures added accessibility for disabled and mobility impaired passengers.

As part of the company’s effort to increase efficiency and to reduce vehicle emissions, Hyundai equipped the all-new bus with a 384 kWh water-cooled high-efficiency polymer battery, with a maximum 186-mile driving range on a single charge. A full charge can be completed in 72 minutes.

The vehicle is 42 feet long and 13 feet high. It runs on an independent suspension system in the first driving axle for a more comfortable ride, and a 240kW wheel-motor axle combined with a motor in the second axle that minimizes loss of electricity.

A rear-wheel steering system works in coherence with the steering system of the first axle, optimizing steering performance.

Various advanced safety features are also equipped on the bus to ensure the safety of the passengers:

• Vehicle Dynamic Control (VDC) helps identify the driver's intended driving direction and maintain the vehicle in control.

• Forward Collision-Avoidance Assist (FCA) uses the car’s front-facing camera to help detect an imminent collision and avoid impact or minimize damage by braking autonomously.

• Lane Keeping Assist (LKA) helps prevent accidental lane departure by sensing road markings.
