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.

European commission investigating F1 finances and anti-competitive accusations

The Kingdom of Formula One reminds us of renaissance Florence - ruled by a singular chieftan behind a mask of representative involvement, rife with spectacularly convoluted machinations, awash in innovations that help define our world and far-flung, vindictive misery. If we found out Bernie Ecclestone's real last name was de Medici, well, it would explain a lot. Now after a bit of back-and-forth, the European Commission (EC) has taken aim at the kingdom, investigating whether F1 is anti-competitive and if the FIA has abused its antitrust agreement. The reason for EC scrutiny is that a British member of the European Parliament who represents an area in southwest England, Anneliese Dodds, has fielded complaints from engineering companies in her constituency that recent moves in F1 have put them out of business. She wrote to the EC to question why the FIA now has a stake in F1 when it signed an agreement in 2001 to be solely a governing body and abdicate any stakeholding in the sport. She also questioned the F1 Strategy Group, a group of the six top teams in F1 that makes decisions about the direction of the sport; she says that the Strategy Group not only appears to be a case of the F1 shirking its rule-making duty, it has resulted in unfair treatment of the small teams that aren't in the group. Dodds has a bit of a point. In 2001, the FIA sold F1's commercial rights to Ecclestone for 100 years for a sum of $313.7 million. That was done to placate European regulators who insisted that "the role of FIA will be limited to that of a sports regulator, with no commercial conflicts of interest." Although the rights are ultimately owned by the FIA and bring in a $10M fee every year from Formula One, those rights bring in $1.6 billion each year to Formula One Management (FOM), the company that owns F1. When Ecclestone was trying to get the new Concorde Agreement signed in 2013 that governs the running of the sport, the FIA wouldn't sign, saying it wanted F1 to share a larger slice of its revenue – the FIA has been losing money for years, see. To the get the FIA to sign, Ecclestone sold it a one-percent stake in F1 for $460,000 and gave the FIA a $5M signing 'bonus;' whenever F1 has its IPO, that stake is estimated to be worth about $120 million - not a bad return. Yet, according to the aforementioned 2001 agreement, the FIA can't have that equity stake.

Lotus Eletre electric SUV reveal: Tune in today at 2:30 p.m Eastern

The upcoming electric Lotus SUV formerly known as the Type 132 officially has a name. It will be called the Lotus Eletre, and the vehicle’s full reveal is today, Tuesday, March 29. For those curious, Lotus says that Eletre means “coming to life” in some Eastern European languages. If you want to pronounce it properly, Lotus provides the phonetic spelling: “El-etra.” Basically, the "e" at the end is to be pronounced as an "a." Beyond the name announcement, Lotus doesnÂ’t have anything extra to share with us today. The name itself was revealed in a dramatic fashion, as a specially-made yellow cube containing the car was piloted up and down the River Thames in central London. Boats and cars being in the same news story as of late havenÂ’t always been for good reasons, but thankfully, this one seems to have gone just fine. If you want to watch the reveal live, make sure to tune in here at 2:30 p.m. ET Tuesday. WeÂ’ll have the live stream in this post waiting to start, so you can check back in right here at reveal time.
