Metro Transit recently began operating two new super-hybrid buses. Dubbed "the Xcelsior," its been called the cleanest bus in the United States. More efficient than other hybrid buses, the Xcelsior shuts down entirely when stopped, rather than idling and wasting fuel. The super-hybrid buses are also manufactured locally, using technologies and parts developed and built in Minnesota. KFAI’s Sarah Lageson talked with Metro Transit staff and Minneapolis bus riders aboard the #10.
