The data provided in the table below is derived from the London Buses route test cycle at Millbrook Proving Ground. This enables vehicles to be compared in an identical way. The comparison shows that the Euro V New Routemaster is 20 per cent more fuel efficient than the hybrid diesel-electric Euro V average for the fleet and emits under a quarter of the nitrogen oxide (NOx).
