The English can't resist a good retro revival: we fell back in love with the new Mini and Doctor Who, so now it's time to do the same with the eco-friendly revamp of the Routemaster bus. Packed with a hybrid engine that doubles the fuel efficiency of a standard diesel (at 11.6mpg -- but it's a bus, so that's a lot) but producing only half the emissions. It'll carry 87 passengers and the vehicle heralds the return of the rear-door, so when it's stuck in traffic, you can safely hop-off and walk the rest of the way. A fleet of eight buses will run London's "38" route from early next year and you can watch the prototype being hand-built in the video we've got for you after the interval.
