Zero emission mode in the city centre, diesel powered for the rest of the route. The British manufacturer Alexander Dennis delivered 30 new hybrid buses to Brighton & Hove (they will start operations in October).
These vehicles will set a very first in the UK: in fact the buses will be converted in full electric every time they enter the city Ultra Low Emissions Zone (ULEZ), according to the practice called geofencing that for the first time has been combined with zero emissions technology in the UK.

The Enviro400ER buses, equipped with BAE Systems’ series hybrid technology, are moved via an electric drivetrain and can run for up to three miles in electric mode, according to the manufacturer.
The buses run on batteries (32 kWh on board), topped up via regenerative braking and a small Euro VI engine used as a generator, if needed, when the bus is outside the zone. They don’t need to recharge in the middle of the day. This keeps buses in service and eliminates the need for the city to invest in charging stations.
The Enviro400ERs don’t have mirrors but instead have two high-definition cameras on the front, relaying pictures to monitors inside the driver’s cab.
