Two types of buses operate on route 55: three fully electric buses and seven electric hybrids, all from Volvo Buses. The electric buses are concept vehicles while the electric hybrids are commercially available.
The electric bus is quiet, exhaust emission-free and about 80 per cent more energy-efficient than a conventional diesel-powered bus.
The electric bus is equipped with an electric motor powered by lithium-ion batteries. Whenever the bus slows down, the resulting ‘engine-braking’ effect generates electricity that is used to charge the batteries – power that would otherwise be wasted. Recharging also takes place via the mains electricity grid at the two end stops, at Sven Hultins plats (Chalmers) and Teknikgatan (Lindholmen). Recharging takes about six minutes and is more than sufficient for the entire route.

Passenger wishes for a pleasant environment and practical functions on board have impacted the design of the electric bus in several ways. For instance, all entry and exit takes place quickly and conveniently via an extra-wide door opening in the middle of the bus. There is a large open space with a low and flat floor to make things easy for passengers with child buggies or wheel chairs. The electric bus is 10.7 m long (approximately 1.3 m less than a conventional bus) but has room for up to 86 passengers.
The driver’s seat is centered which contributes to the high passenger capacity. The interior is bright and airy. The white, arched roof panel creates an aura of space and features background lighting to give a warm and inviting light. The colour scheme is dominated by matching shades of green. The seats are upholstered in jacquard-patterned wool fabric.
The bus is equipped with WiFi and USB ports for passengers who want to surf or charge their mobile phones, as well as displays for information and news.

The electric hybrid, Volvo 7900 Electric Hybrid, combines an electric motor and batteries with a smaller diesel engine. It runs emission free on electricity for approximately 70% of a normal route and cuts energy consumption by 60% compared to a conventional diesel bus. Just like the fully electric bus, the batteries in the electric hybrid are charged when braking and via the electric grid at the route’s end stops.
Also the Volvo 7900 Electric Hybrid has a bright and airy interior, WiFi, USB ports and information displays to offer the passengers a positive experience. The bus is 12 m long, has a low, flat floor and room for up to 95 passengers. The Volvo Electric Hybrid is part of the Volvo offer. Outside Gothenburg the buses are in daily operation in Hamburg and Stockholm.
