Developed with BAE Systems, the Enviro400ER offers geofenced zero-emission capability, and can run for up to three miles in electric mode.

Based on the same technology as the manufacturer’s existing hybrid buses – of which 1,400 have thus far been built – the new vehicle utilises a 32kWh capacity energy storage system, comprising third generation lithium nickel manganese cobalt battery technology, including the same components as the latest generation-Enviro400H.

The battery does not need external charging, which helps to avoid infrastructure costs in depots and termini.

Brighton & Hove Buses is the first UK operator to order the new vehicle; 30 will join the Go-Ahead subsidiary’s fleet later this year for use on route 5, and will run in zero-emissions mode in the town centre.

Arthur Whiteside, Managing Director UK Sales at ADL, said: “Improving air quality is on everyone’s agenda and ADL supports these efforts with the market’s widest range of low and zero emission buses.

“Our new Electric Range option offers a highly cost-effective way of introducing zero emissions capability with no need to change operational practices.”

Ian Wilson, Director of Business Development at BAE Systems, added: “Our proven Electric Range hybrid technology provides an innovative and practical solution that is used in thousands of buses worldwide.

“This system delivers low emission operation wherever there is emerging demand for clean air zones, without the complication and expense of charging infrastructure.”
