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 signs Pastor Maldonado to replace Raikkonen

The team currently known as Lotus has had a long string of accomplished drivers behind the wheel, including world champions like Nelson Piquet, Michael Schumacher, Jenson Button, Fernando Alonso and Kimi Raikkonen. But Kimi is returning to Ferrari next season, leaving a big question mark over who would fill his seat. And now we have our answer.
Lotus has just announced that it has signed Pastor Maldonado to partner with Romain Grosjean for next season. The surprise winner of the 2012 Spanish Grand Prix has been driving for Williams for the past three seasons, signed after he won the GP2 title in 2010. Though lauded as an emerging talent, Maldonado is clearly not the accomplished champion Raikkonen is, however Lotus apparently needs the money which Maldonado brings with him in the form of sponsorship from the Venezuelan state oil company PDVSA.
Meanwhile, Romain Grosjean, also a former GP2 champion, has been with the team for some time now, starting as its test driver in 2008, promoted for one season to the race seat in 2009, and returning again in 2012. He's been the second driver at Lotus ever since, achieving career-best second-place finishes at the 2012 Canadian Grand Prix and 2013 United States Grand Prix. Whether it will be Grosjean (who gets the higher number) or Maldonado that emerges as the dominant force at Lotus remains to be seen. Scroll down for the complete press release.

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.
