The Stig bungees a Lotus F1 car in Durban

Remember a couple of months ago when a mischievous Stig broke into the Lotus racing headquarters in Enstone and made off with an F1 car? Well, now we know where he went with it.
In this humorous clip from Top Gear, the tamed racing driver in the white suit disembarks with Pastor Maldonado's Lotus-Renault E22 (not the E21 he took from the team's headquarters, eagle-eye viewers might notice) in Durban, South Africa, and takes it to Moses Mabhida Stadium for the Top Gear Festival. After having some fun on a dirt bike, a chrome Mustang drift car and a few other curiosities, he hooks it up to a bungee cord and jumps off a tower behind the wheel.
Now we're not quite convinced they actually did this and that it wasn't all CGI, but it's still worth a watch and a laugh.

Lotus and Aston Martin to hook up?

This has been a tumultuous year for Lotus - to say the least - from the company being sold off back in January to its CEO Dany Bahar being fired in June to its questionable financial status and rumors of the British automaker being sold off to another automaker. First, we heard that Volkswagen was interested in acquiring Lotus and parent company Proton, a rumor that was later dismissed. Now Automobile is reporting that fellow Brit Aston Martin could be in the market to work with or possibly even merge with Lotus.
While this is pure speculation at this point, such a venture could prove to be beneficial for both independent companies. That's because with Lotus focused on lightweight, relatively affordable sports cars and Aston Martin producing high-end performance cars, there is virtually no product overlap between the companies. The article suggests that a person or company wanting to merge these two automakers would have to raise between $1.1 billion and $1.6 billion in order to make a go of it, however.
We're not sure what to think of this latest rumor, but anything that can help get the struggling brand back to health at least has our interest.

This is how ground effects work in a nutshell

There are two ways to generate downforce. One is with all manner of wings and spoilers on the surface of the vehicle. The other is with ground effects. One you can clearly see, the other remains something of a hidden mystery. Fortunately, the good folks at Lotus and Goodwood are here to dumb it down for us non-engineer types. It's called Bernoulli's Principle, named after Swiss physicist Daniel Bernoulli who literally wrote the book on the subject way back in the 1700s. Countless engineers have spent their careers focused on its study and application, but the crux of the matter is that, as the speed of air (or other "fluid") increases, pressure decreases. Play with the air's increasing speed and decreasing pressure just right and you can generate downforce underneath the body of a car without significantly increasing drag as you would with surface spoilers. For evidence of how Bernoulli's Principle applies in practical terms, just look at the last Ferrari to pack a turbocharged V8 in the middle and the latest one. The F40 had a giant wing on the back, where the 488 GTB has none. But because the 488 uses underbody aerodynamics (or "ground effects"), it generates significantly more downforce than the winged F40 ever could, and at lower speeds. Ferrari, however, was not the first outfit to harness the power of ground effects. Lotus did with the legendary 79 that Mario Andretti drove to the world championship back in 1978. That was the genius of Colin Chapman, and to explain how it all works in layman's terms, our friends over at Goodwood Road & Racing brought in Colin's son Clive Chapman, head of Classic Team Lotus, to put together the video above.
