The Volvo B5L (sometimes known as the Volvo B5LH or Volvo BRLH) is a hybrid-electric powered bus built by Volvo since 2008. The design of the chassis is similar to that of the Volvo B7L. It could be fitted with Volvo's own I-SAM parallel hybrid drive system and Volvo D5E engine. It can save up to 35% on fuel consumption and reduces the emission of green house gases, including carbon dioxide.
