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.

Lotus could be sold to Chinese automaker Geely

Two things are constant throughout the history of Lotus Cars: amazing vehicles, and financial struggles. Frequent changes in both ownership and leadership have left the company's future up in the air. And while the new management has improved quality and set a new product plan in place, its seems that Lotus could have a new parent company soon. Despite comments to the contrary, Chinese automaker Geely is rumored to be interested in acquiring Lotus Cars. The British automaker has been owned by Proton since 1996, but after Proton was sold to DRB-Hicom in 2012 investors suggested selling off Lotus. The Star Online reports that PSA in France is rumored to be looking at purchasing Proton cars from DRB-Hicom. In turn, Geely, the parent company of Volvo, is interested in purchasing Lotus from Proton. The report states that Geely has no interest in mass-market vehicles from Proton, while crossover-focus PSA, owner of Peugeot and Citroen, has no interest in a sports car manufacturer like Lotus. China has been encouraging its native automakers to purchase and acquire technology it lacks. Buying Lotus looks like it would benefit both companies. Lotus needs an influx of cash while Geely, looking to compete further on the global stage, would gain a great deal of technical and engineering knowledge from Lotus. Geely's stewardship of Volvo has been mostly hands-off, while giving the Swedish company enough money to invest in new platforms and technologies. If the same were to happen to Lotus, Colin Chapman's company could have its best years ahead of it.

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.
