RE: Arriva North West - St Helens Depot
Its a system called ecnospeed thats been fitted to reduce the amount of fuel going through the engine to reduce fuel usage and lower emissions which in turn slows the veichles down.
As far as im aware some have been turned off which you can tell which ones they are as they are able to get up hills etc.
