GKN partners with Alexander Dennis to accelerate introduction of low carbon bus fleets

In a step towards affordable, low emission buses, GKN and Alexander Dennis Limited have signed a deal that will see the introduction of 250 greener, cleaner vehicles to transport fleets across the UK during the next two years.

As part of the agreement ADL – Britain’s biggest bus and coach manufacturer – has chosen GKN Hybrid Power as a preferred partner and committed to the purchase of 250 of its leading-edge Gyrodrive electric flywheel systems.

ADL will focus initially on the introduction of the low emission technology to bus fleets in London and Oxford but anticipates rapid deployment across the UK in the next few years. It will also be working closely with GKN to develop the technology for international markets.

The Gyrodrive system uses a high speed flywheel made of carbon fibre to store the energy generated by a bus as it slows down to stop. It then utilises the stored energy to power a GKN EVO electric motor which helps accelerate the bus back up to speed, generating significant fuel savings at a considerably lower cost than battery hybrid alternatives.

ADL’s Euro6 Enviro400 bus, the UK’s best-selling double deck – fitted with the Gyrodrive system - recently achieved low carbon emission bus certification, which acknowledges a 30% reduction in greenhouse gas emissions and entitles operators to enhanced fuel rebates.

The Gyrodrive system is designed to last for the life of the bus eliminating the need for any battery changes and offering much lower whole-life costs than other hybrid alternatives, making it a truly viable proposition commercially.

Based on Formula One race technology developed in the UK, the innovative GKN system will help increase the efficiency of every bus to which it is fitted by using less fuel and therefore reducing carbon emissions. This same technology helped Audi’s R18 e-tron win at Le Mans in June, Audi’s third consecutive win with GKN’s flywheel.

Earlier this year transport operator go-ahead group selected GKN to supply 500 systems for use on buses in cities across the UK following successful trials in London.

GKN Hybrid Power is based in Oxfordshire, with final assembly taking place in a new facility at GKN’s site in Telford. The Gyrodrive technology is being further developed for other mass transit markets including trams, construction and agricultural equipment. Earlier this year GKN announced the acquisition of Williams Hybrid Power from Williams Grand Prix Engineering Limited to form GKN Hybrid Power, which is focused on delivering complete hybrid solutions across multiple vehicle, power and industrial markets.
