Isuzu Erga

The Isuzu Erga (kana:いすゞ・エルガ) is a heavy-duty single-decker bus produced by Isuzu through the J-Bus joint venture. It is primarily available as a public bus in either a complete bus or a bus chassis. It is built by J-Bus from Japan either as a step-entrance bus (One-step and Two-step) or a low-floor bus (Non-step (Type A and Type B)).

First generation (2000-2015)
The styling is completely different from the Cubic. 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. Its Hino-rebadged version is the Hino Blue Ribbon II.

Isuzu Erga Duo
ERGA DUO, the first mass-produced articulated bus made in Japan, debuted on May 27, 2019, along with the Blue Ribbon Hybrid articulated bus. The hybrid mechanism is the same as the HL series Erga hybrid.

The model is called LX525Z1. 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.

Like the Hino blue ribbon hybrid articulated bus, the brakes are the only all-wheel disc brakes in Japanese large buses.

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.

Isuzu Erga-J
The Isuzu Erga-J is a rebadged Hino Rainbow HR. It has a rounded roof dome similar to the Erga with a deep double-curvature windscreen and a separately mounted destination display.
