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 plans detuned Evora sans supercharger for US market

We may never see a new version of the Elise or Exige in the United States, but the legendary British marque has been steadily rolling out new versions of the Evora 2+2 sports car. According to Automotive News, the automaker based in Hethel is planning a detuned version of the Evora to help it get in line with US emissions regulations. "Over a five-year period in the U.S. we have to show a 3 percent per year reduction in carbon dioxide emissions," Lotus CEO Jean-Marc Gales told AN. "One option is remove the supercharger." Gales apparently feels that's a better option than downsizing to a 2.0-liter turbo four, which would require more reconfiguration than simply removing the supercharger. The former Peugeot chief cites the example of another British sports car manufacturer in McLaren, which detuned the 3.8-liter twin-turbo V8 from the 650S to slot into the 570S. In any event, the base Evora wouldn't be the only new version of the model we're expecting to see. The company recently rolled out the revised Evora 400, and revealed the even sharper Evora Sport 410 (pictured above) at the Geneva Motor Show last month. Lotus also has an Evora roadster in the works that's similarly targeted at the North American market. Following the base model, we wouldn't be surprised to see even more variants to follow.

Renault settles on Lotus, to take 65-percent stake in F1 team

Renault's coquettish moves toward becoming a constructor again have been news all season. The expected maneuver, should Renault say "Oui" to such, was for the French carmaker to repurchase the Lotus team - the team it sold at the end of 2010 to Genii Capital. Then last week we got the surprise news that Renault had been talking to Force India about taking a majority stake, but that information came with the context that Renault had discussions with several teams about such a move. Autosport reports that Renault has finally decided to get back together with Lotus, taking a stake worth up to 65 percent for 65 million pounds. The deciding factor was said to be the facilities that Lotus has available compared to Force India, including the Enstone factory formerly owned by Renault, plus a computational fluid dynamics program, driver-in-the-loop simulator, and a 60-percent-scale wind tunnel. The final shareholding stake will be split between Gerard Lopez at 25 percent and Renault ambassador Alain Prost at 10 percent. Renault will make a 7.5-million-pound payment immediately, completing the acquisition by paying 5.75-million-pounds per year for the next ten years. On top of that, Renault will invest a budget commensurate with those of Mercedes-AMG Petronas and Infiniti Red Bull Racing. The carmaker's board and CEO Carlos Ghosn have approved the deal, it is up to Lotus shareholders to agree to everything by Monday, when Autosport says the papers will be signed. The deal puts team drivers and the Red Bull engine supply in question. It should be expected for Romain Grosjean to remain, but keeping Pastor Maldonado is not a certainty. As for engines, Red Bull's engine supply contract states it must be Renault's priority, so Renault could stick with the Mercedes power unit Lotus currently uses for one more year, or help Red Bull get in bed with Mercedes. We should know more next week. Related Video:
