Save more than 30% on your fuel bills
The fuel savings will depend very much on the kind of operation but savings of 30% have been achieved by many operators in mixed traffic.
As our experience and that of operators has increased, so full savings have improved. The driver still plays a key role in delivering fuel savings and we undertake training with every new customer to highlight the special features and information available to the driver on the Volvo Hybrid. We are confidently expecting a further fuel improvement with the Euro 6 version.
CO2 reduction: 27 tonnes a year per bus – 12 g per passenger per mile
We estimate that operating one of our hybrids for a year will improve the operator’s carbon footprint to the tune of 27 tonnes of carbon dioxide. Typically that means 12 g less carbon dioxide per passenger mile so the more hybrids in the fleet, the better the result. This is useful to know in the debate about transport priorities in towns and cities in the future.
No 1 in uptime
Some still believe that hybrid buses are sensitive and less reliable than conventional buses. Well that’s yesterday’s news. The Volvo Hybrid has demonstrated top level availability and is backed with our usual warranty (“2+1” years, complete vehicle and driveline) with the added benefit of 5 years on the hybrid battery. We are taking risk off the table for the operator.
Air Quality Emissions also down
Particulates and NOx (Oxides of Nitrogen) are very sensitive air quality emissions that are very much on the Agenda for many cities and towns across the UK. The Volvo Hybrid delivers significant benefits in this area, not least because of the pure electric pull away from bus stops. The improvements are expected to be even more significant at Euro 6. The reduction of CO2 matches the fuel saving.
Silent take off
Right from our first Hybrid delivered in the UK in 2009, Volvo has offered engine shut down when the battery state of charge is in the correct range. The Volvo 7900 can pull away silently from bus stops or traffic lights up to around 10 mph with the diesel engine shut off, before the diesel engine smoothly re-engages. This also reduces noise and improves passenger comfort, and means zero emissions too. In slow moving traffic, the careful driver can maintain electric mode for almost 1 km.
The doors of a bus are subject to very heavy use. Our new electrically-powered doors on the 7900H offer smooth operation and improved maintainability (and reduced services costs). What’s more, the electric doors also contribute to even more fuel savings!
Much more than just city-centre operation
Another myth concerning hybrids is that they only save fuel in really dense city traffic. But in reality the savings are substantial in the suburbs too. Many of our customers confirm fuel savings of 25% or even more in environments where hybrids were not originally intended to operate. The Volvo 7900 Hybrid continues to exceed expectations.
