New heart for busesAutomotive engineer Haidee Che Rizmin likened the retrofitting plan to giving old diesel buses “a new heart” by allowing them to operate at a performance level close to that of a new vehicle. Haidee likens the retrofitting plan to giving old diesel buses “a new heart”. “Electrifying old diesel buses is a strategic approach for Rapid Bus, as it is about 30% to 50% cheaper than acquiring new electric buses,” he said. Cheong noted that retrofitting diesel buses would offer immediate environmental and public health gains by eliminating tailpipe emissions. “While the upfront cost is more than a diesel bus, electric buses are cheaper to run and maintain in the long term,” it added.
