The Superbus is a prototype high speed electric coach-like limo car that is capable of carrying 23 passengers at speeds of up to 250 kilometres per hour (160 mph) on specially designed segregated highway lanes. The Superbus project, led by Dutch astronaut professor Wubbo Ockels of the Delft University of Technology until his death in 2014 envisages a comfortable, demand-dependent door-to-door transportation rivalling the car and the train. The project, which encompasses infrastructure, logistics, safety, reliability and economic viability, in addition to the design of the vehicle itself, has received funding of €10 million, largely provided by the Dutch State.
