The LFS Hybrid is essentially an electric bus with an onboard diesel generator to produce electricity to recharge an onboard battery as needed. Unlike for electric buses, the battery is not recharged overnight. These diesel-electric buses use 25 percent less fuel than a diesel bus. Also, energy produced by descending a hill or braking will help recharge the battery. The bus is driven by an electric motor with electricity drawn from the on-board battery. On-board systems such as doors, HVAC, power steering, etc. are electrically powered.
