From concept to reality: Isuzu Erga EV bus revealed with 360 km range

During last year's Japan Mobility Show (JMS), Isuzu revealed not one but two commercial EVs. One of those is the Erga EV concept, a near-production version of Isuzu's first-ever flat-floor electric bus. At the time, Isuzu only showed a prototype version of the people carrier at Tokyo Big Sight. However, they did say that a production version will be revealed in 2024.

Fast forward to the present day, Isuzu Motors Limited (IML) launched the production version of the Erga EV. Billed by the company as Japan's first BEV (battery electric vehicle) flat-floor route bus, the all-electric bus will be at the forefront of next-generation buses in Japan and perhaps in other markets as well.

Just like the prototype version shown before, the Erga EV features a pair of “in-axle” motors wherein the electric motor is built into each side of the rear axle. Combined with the battery packs placed on the roof and under the floor, this allowed Isuzu to make a barrier-free layout that maximizes space as well as the aforementioned flat-floor configuration. Add to that the smooth acceleration from the electric motors and you have a comfortable people carrier.

Speaking of motors, Isuzu says the Erga EV's motors produce a combined 340 PS and a healthy 960 Nm of torque. Power is supplied by a massive 245.3 kWh lithium-ion battery that Isuzu claims gives the Erga EV a range of up to 360 km (constant speed of 30 km/h). Recharging the Erga EV is done via a quick-charging CHAdeMO system rated at 50 kW. This allows the bus to recharge from 20% to 80% in 3.2 hours. In times of disaster, the Erga EV also comes with a V2L (vehicle-to-load) feature to power up devices or appliances.

In terms of size, the Erga EV measures 10,545mm long, 2485mm wide, 3330mm tall, and has a generous 4990mm wheelbase. A total of 70 passengers can fit inside the Erga EV including those that are standing. For added safety, the bus also features a driver monitoring system which ensures passenger safety. In the event the driver is incapacitated, the Erga EV also comes with the Emergency Driving Stop System (EDSS) which can bring the vehicle to a safe stop. Last but not least, it has a blind-spot monitoring system that alerts drivers of pedestrians or other vehicles beside the bus.

Isuzu plans to sell around 150 units of the Erga EV per year in Japan and is part of the brand's move towards carbon neutrality in public transportation. While it will only be offered in its home market for now, we won't be surprised if Isuzu decides to bring the Erga EV to other markets in the future.
