"A new Dutch invention can make cars, busses and other vehicles no less than 50 percent more efficient and thus more environmentally friendly. Better still, the technology is already available; it all comes down to a smart combination of existing systems.
This winter, in the city of Apeldoorn, a city bus will be used to prove that the claims about the new invention are true. These are quite bold. E-traction, the company that developed the bus, boasts fuel savings of up to 60 per cent, with emissions down to only a fraction of the soot and carbon dioxide an ordinary bus would blow out of its tailpipe.
In addition, the test bus requires no adaptation, its drivers need no extra training and there'll be no discomfort for passengers. It will simply run on diesel, just like all the other buses, and it should be just as reliable. One thing however will be very different; the Apeldoorn bus hardly makes a sound, hence its nickname "the whisperer".
In-wheel engine
All this is made possible by an ‘in-wheel' electric engine, in fact nothing more than a normal electric engine turned inside out."
