Pedal power: Check out the gold Porsche made of CARDBOARD (with a top speed of 10mph)

Austrian Johannes Langeder is the proud owner of what is arguably the world's cheapest 'Porsche'.

Unlike run-of-the-mill sportscars of this calibre, his vehicle is built entirely from cardboard, and fitted onto a skeleton made of plastic tubes and aluminum foil, held together by duct tape.

Johannes, 48, invested a total of £11,000 and 1,000 hours of hard work in this project, from the design stages to getting the car road-ready.

The 'Porsche' weighs just 99.6 kilograms (219.5lbs), and can reach a top speed of 10 miles per hour with lots of pedalling.

'It has 24 gears which is pretty impressive, and at the end of the day I am finally driving around in a Porsche,' he said.

The car is legally allowed on the on the streets of Hamburg, where the eccentric owner lives, because it is technically a bicycle. One hidden under a cardboard replica of a Porsche, but a bicycle, nonetheless.

'It is treated like a bicycle by the law and I wanted to show that a car needed no fuel. Most car drivers need a second look before they realize it is technically a bicycle. Most of them are very enthusiastic and get their cameras out,'  Johannes added.

His Porsche is also the most environmentally friendly model currently on the roads, releasing zero emissions and running entirely on pedal-power.
