When the Nurburgring->ke999 was created in 1925, its main purpose was to become a safer alternative to public road racing. After 90 years and many modifications, the Nurburgring is one of the most popular race tracks in the world. However, the German course is not just about racing->ke447 and open days; carmakers have been using it as a test track for many years.

We've seen countless videos->ke278 of just about every type of vehicle being put through its paces on the "Green Hell," courtesy of enthusiasts that spend their days around the track. One of them is veteran 'Ringhound and YouTube user "cvdzijden," who has just released a compilation that highlights how various automakers test their new cars on the 'Ring.

The footage is interesting to say the least, as it shows the various techniques companies use to hone their vehicle before sending them to dealerships. It's not just about pushing it to the metal on the straight and looking for that perfect racing line in the bends. There's also a lot of powersliding, coasting and jumping. Granted, most customers don't get to drive their cars as factory test drivers do, but these techniques are essential in preparing a vehicle for production.

Of course, tests like these can also result in crashes, and this video shows an Audi Q7->ke1083 losing grip and slamming into a barrier. Then there's the Bentley Mulsanne,->ke3495 which seems to be in no hurry to lap the 'Ring. Other vehicles featured in the video include the Porsche 911,->ke282 Bentley Bentayga,->ke5088 and the Mercedes-AMG C63. Hit "play" to see how various automakers test their cars on Germany's iconic track.
