Video shows a group of engineers working on a suspension system that would allow the A5 to lean when curving.

Here is a video which shows a group of engineers working on a suspension system that allows the A5 prototype seen here to lean into curves.

Now, our colleagues at Autoblog.com believe this may be an April Fool's joke. But the original story from Cocheafondo.com says that Audi is working on the leaning suspension technology and using this A5 3.0 liter TDI as a prototype.

We're not quite sure what to make of it. It's could be just an experiment as part of Audi's suspension development.

Or it's a group of students doing something fun on their own - those chaps in the video do look young.
