We've seen Porsche-alike pedal cars before but this is something entirely different – a full-size replica 911 with a two-seater recumbent bicycle instead of an engine.
Called the Ferdinand 911 GT3 RS – the RS stands for Rad (cycle) Sport, and Ferdinand was the founder of Porsche – this Austrian invention weighs a whopping 99,637g (220lb) despite an "ultra light construction" and "luxurious outer appearance" which looks suspiciously like tinfoil to us.
Oversize air inlets keep the rider/driver cool, steering is courtesy of a pair of bike handlebars, the wheels are shod with skinny (for a car) Schwalbe Crazy Bob mountain bike tyres and the rear spoiler is said to give a "safe feeling" when pedalling at speed – assuming you have the leg power to get it moving.
As the narrator of the video below explains: "Because of economic reasons the Ferdinand GT3 does not have an engine. On the one hand this provides an enormous loss of weight; on the other it reduces the emissions to a low level, breaking records. Another side effect is the enormous trunk."
