Greener Double-Decker London Buses Win Competition

The Aston Martin and Foster design is a zero-emissions double-decker that is highly maneuverable, with warm lighting and wooden floors and is accessible for disabled passengers. There will be reconstituted leather upholstery to create a tactile "living room" feel. The top of the bus will have a glazed roof which incorporates solar cells to "generate energy and filter daylight to control the temperature inside."

Capoco's proposed bus has a low flat floor to allow passengers to get on and off easily, with a Routemaster-like front engine, an open rear platform; it will also be low emission.
