Volvo 7900 -B 9 L Chassis

Easier maintenance

The side panels are manufactured from fiberglass and various plastic materials and are glued together. Fiberglass and plastics are light materials that produce smooth and attractive sides on the bus and the side panels are particularly easy to replace if they are damaged. The new design also means that many components are screwed on, making it possible to conduct repairs without needing to weld.

“Replacing such components that are frequently damaged, for example, the bumper corners and the area around the wheel housing, will be rapid and simple,” says Stefan Guttman.

The predecessor, the Volvo 7700, was manufactured in steel and the company was able to significantly reduce the weight with the new design. For example, the Volvo 7900 hybrid version is a full 550 kg lighter than the current version.

“When the buses become lighter, this generates space for our customers to accommodate more passengers and still fulfill weight requirements,” says Stefan Guttman. “For example, as a gas-engine articulated bus, the Volvo 7900 will be able to take 14 more passengers than its predecessor.”

Diesel or gas powered

The diesel engine is Volvo’s fuel-efficient Volvo D9B, with 260, 310 or 360 hp. The engine fulfills the Euro V requirements and an enhanced environmentally friendly vehicles (EEV) version is also available, with particle filter. The gas engine is the 300-hp Volvo G9B. It can operate on both CNG and biogas.

Customers are able to choose automatic transmission from either ZF or Voith. The Volvo 7900 Hybrid has the same efficient hybrid driveline as in the past, with a five-liter diesel engine, an electric motor and the Volvo I-shift transmission.
