Before we cared about trees and not causing the earth to become a fiery, uninhabitable mass, the automotive world was fixated on creating concepts that pushed the limits of what's possible on four wheels. Some companies still throw caution to the wind, such as Bugatti, Ferrari and Lamborghini, but most of the time you have to look back to see some of the most iconic machines ever designed.
We've rounded up 25 of our favourite experimental cars, from the very first concept car ever to 21st century automotive pin-ups – and just about everything in between. So – in no particular order – let's get on with the show.
Leaving aside that dated background, it's hard to tell the space-age Ford GT90 was first revealed to the world more than 17 years ago. Pumping out 720bhp from a quad-turbocharged V12, it could accelerate to 60mph in 3.1 seconds and up to 100mph in 6.2 seconds, before going onto a lightning top speed of 235mph. We're talking Bugatti Veyron performance, but way before it even existed.
Because of the heat spewed out from the V12, the spiritual successor to the GT40 was said to use Space Shuttle ceramic tiles to keep the exhaust from melting body panels.
