Economy and the environment
When Volvo first presented hybrid buses a decade ago it was assumed that some 20% of fuel could be saved. This would give substantial environmental benefits and cost savings. When reports started to reach us we instead saw savings of 25%, then 30% and even 40%. Our hybrid technology started to pay back from day one.
The introduction of the Volvo 7900 Electric Hybrid took electromobility one step further. 75% less fuel, but perhaps even more important, it could operate silently and with zero emissions. The cost of noise to society is often severely under-estimated. New regulations governing noise for public health reasons means dramatic cost increases, but with electrified buses much of this can be avoided.
