Riding Volvo 7700 Hybrid

Yesterday, I took the bus to go shopping. Not, just any bus but the 7700 Hybrid, going from one end of the line 30 to the other. The passengers surely noticed the difference. Some changed from another bus to the hybrid just for the fun of riding with the first 7700 hybrid in traffic.

I talked to Omer, the driver. He is one of the selected 12 drivers that have been driving the bus for two weeks now. He is very happy with it, he say. The silent driving is the best feature. He is also quite impressed by the take-off and smooth behaviour of the drive train. And, his bad back in particular appreciate the air suspended driver seat. He has not yet heard about the fuel consumption data.

I logged the rout with my GPS. With an average speed of 20 km/h and some 30% idle time I estimated the cycle to be similar to the Braunschweig cycle or SORT 2. I said to Omer that with strong reservations for the short sampling time we could expect a fuel consumption decrease by about 30% giving about 30 litre per 100 km.

The first two stops we were just three passengers. The closer we got to the end the more passengers entered the bus, ending up with a patronage of 30 persons.

At the end stop Omer told about his 6 year old daughter that now tell her friends that her daddy now drives the “battery bus”. Omer also revealed that his engagement in the bus also affected him privately and that his next car will not be a natural gas car and not an ethanol car but a hybrid car, because it is of highest priority to decrease the use of energy.

I was speechless.
