Future Bus

The Delft University of Technology in the Netherlands is developing another bus, which is able to operate on designated tracks. Future Bus is able to operate at very high speeds of up to 250 kilometres per hour (155 mph) and could therefore be an alternative to high-speed railway lines.

This highly streamlined electric bus can also be driven at lower speeds on existing roads and bus lanes. With a length of 15 metres (49.2 ft) and a width of 2.5 metres (8.2 ft), the Superbus has similar dimensions to a conventional bus. Due to the seating arrangement without a centre aisle however, the height is just 1.7 metres (5.6 ft). The low aerodynamic drag (less than 0.2) makes the Superbus more efficient than a passenger car.
