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 F1 Team Breaks World Record For Longest Truck Jump

Lotus F1 wasn't content to make just any commercial for their technology partner EMC Industries. It had to be one for the record books. The video released over the weekend shows a truck breaking the world record for longest jump ever completed by a truck. The stunt was obviously geared towards publicity, but while they were at it, they set a Guinness World Record for the longest truck jump at 83 feet, 7 inches. The previous record, according to Guinness, stood at 50 feet, 6 inches, and was set on MTV's Nitro Circus on November 17, 2008, by Gregg Godfrey at Rocky Mountain Raceway in Salt Lake City. That record stood for six years, but (as best we can tell) was set without the trailer attached, or the F1 car tracking underneath - which only makes this latest stunt that much more impressive. Stunt driver Mike Ryan planned the jump and drove the truck off the ramp and over fellow stunt driver Martin Ivanov as he sped underneath in a Lotus F1 race car. And just so you know no CGI was involved, EMC industries included a making of video on their website.

Renault paid GBP1 to buy back its F1 team

Running a Formula One team is anything but cheap and straightforward, but it didn't cost Renault much to reacquire the Lotus team from Genii Capital. In fact, according to the latest reports, the French automaker paid just GBP1 – less than a buck fifty – for the privilege. Still, the process was deeply complicated. The reason Renault was able to get it so cheap is because the team was deeply in debt, part of which Renault will now assume. Less than a year ago, the team was said to be nearly $200 million in the red, and just a few months ago Renault came to its rescue to pay a $4 million tax bill to the British government. Under the terms of the new deal, Renault will assume the debt that the team's previous owners had accrued, but will be spared the nearly $150 million which its stakeholders loaned to the team. The history of the outfit based in Enstone dates back to 1981 when it was founded as Toleman Motorsport. French fashion giant Benetton bought the team in 1985, which in turn sold it to Renault in 2000. A decade later, after two world championship titles, Renault began stepping back its involvement in the team and gradually transferred ownership to investment firm Genii Capital, which has run it ever since under the Lotus name that it secured from the automaker under contract until 2017. Unable to fund a competitive team, Genii has now sold the team back to Renault, but the financial intricacies of the deal are far from straightforward. To start with, Genii and its subsidiary Gravity Motorsports (the team's parent company) didn't hold all the shares in the operation, so it bought back over 6 million shares from Whiterock Alliance to add to its own 60 million shares. The vast majority of those shares were then transferred (for that princely sum of GBP1) to Gringy (UK) Ltd, the shell company that technically owned the team in its Benetton days. Gringy (a wholly owned subsidiary of Renault) will hold a 90-percent stake in the team, with the last 10 percent remaining in Genii's hands and those of its investors. In the process, the outfit will now rejoin the likes of Ferrari and Mercedes among the F1 teams developing their own powertrains.
