Life-size Lego car runs on air!
This life-size car was built using thousands of Lego pieces, and you can actually drive it! It does have some parts not from Lego. These are the wheels and parts needed to support your weight when you sit in the car.
The Lego car looks like a hot rod. A normal hot rod is built to go really fast in a straight line.

Top speed
Although the car looks like a hot rod, it can only travel 20 miles per hour (20 mph). This is much slower than the 70 miles per hour that you drive on the motorway.
Air-power
No petrol is used. The car’s engine runs on compressed air.

The inventor
It was invented by 20-year-old man called Raul. He is self-taught engineer from Romania, which is a country near Switzerland. He has also made a jet bike!
How does air drive a car?
Think of what happens when you blow up a balloon and pop it. When you blow into the balloon, you are pushing air into a space which is smaller than outside. (Pushing something into a smaller space is called compressing.)
The balloon holds the air tightly inside, but when you use a pin to create a hole in the balloon's surface, the air rushes out with so much energy that the balloon explodes. Compressing air into a small space is a way to store energy.
The Lego car has a bottle of compressed air. When the compressed air is let out it rushes into the engine and moves parts that turn the wheels.
