Volvo B9TL achieves around 7mpg, and a Volvo B5LH achieves around 9mpg.
The GKN modifications are expected to reduce fuel consumption on a Volvo B9TL by 20%.
Even 1mpg difference makes a huge difference to bus operators. When you start multiplying it by the amount of miles on average a bus does each day, then you multiply that by circa 300 for the amount of Monday - Saturday 'normal frequency' journeys, then you multiply the amount of vehicles receiving the modifications...
The modifications soon pay for themselves and deliver huge benefits to the operator, that's for sure. Que the tongue in cheek comments about the fares going down as a result of these savings..!
