The New Bus for London, designed by Heatherwick Studio, is a planned 21st Century replacement of the iconic Routemaster as a bus built specifically for use in London. It is to be built by Wrightbus, and will feature the 'hop-on hop-off' rear open platform of the original Routemaster, but will meet the requirements for modern buses to be fully accessible, and will incorporate an electric hybrid driveline. A prototype is expected to be on the road by late 2011, with the first buses due to enter service in early 2012, in time for the 2012 Summer Olympics.
