The “Flybus” prototype bus aims to showcase how hybrid electric buses can be inexpensive, cost efficient and easy on the environment. Reports out this week say that the Flybus is being readied for testing. The consortium of companies that created the prototype wlll stage a presentation at this year’s Low Carbon Vehicle event in the UK, at Rockingham Motor Speedway in Corby, Northamptonshire.
Transportation engineers will want to see how the Flybus rates in a focus on what is next in the evolution of the hybrid bus and solutions that can ease fuel consumption and CO2 emissions. Cost has been a challenge with standard hybrids.
The new Flybus hybrid has taken on cost considerations with a unique energy-saving approach. The bus makes use of the “flywheel” technique demonstrated earlier this year by Porsche in Detroit. The flywheel can feed energy back into the wheels on the vehicle’s acceleration. The technique is praised as a way to generate emissions-free energy. The system takes the kinetic energy that is generated from the braking stops-and starts of a city bus run and sends it back to the vehicle. The team’s goal has been to come up with an energy-efficient redistribution process, supported by a continuously variable transmission system.
