The Isuzu Erga has a deep double-curvature windscreen and a rounded roof dome (more rounded as compared to the Cubic) with a separately mounted destination display.

It is the first bus in the world with EDSS (Emergency Driving Stop System).

The bus uses A09C 6-cylinder engine, which creates 360 horsepower at 1800rpm, and Hino Motors 7AMT transmission as the GVW exceeds 20 tons.

On August 2, 2022, along with the Erga Hybrid, shipments were suspended under the guidance of the Ministry of Land, Infrastructure, Transport and Tourism due to the Hino Motors engine fraud problem.
