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.

What has Lotus got in store for us in Geneva?

In its latest announcement, Lotus has reported a substantial increase in sales over the past nine months of this fiscal year to date. That's good news for the once troubled niche automaker, but the interesting part was hidden further down the release. After detailing the jump in sales by 54 percent worldwide, Lotus announced that it "is revealing an exciting new car at the important Geneva International Motor Show in early March 2015." While little in the way of details were confirmed, the company said that "the product will remain true to its core pillars of lightness, performance and driving purity by embodying all of them in a most desirable package." Sounds pretty Lotus-like to us, but just what form it will take remains to be seen. Given that the Malaysian-owned British automaker has scrapped all of its ambitious new projects, the overwhelming likelihood is that whatever it is preparing to reveal in Geneva will be based on one of its existing models: the Elise, Exige or Evora. The last we heard, Hethel was planning a revision to the Evora, convertible and even crossover versions of the same, as well as an even more hard-core version of the Exige to take the place of the extreme 2-Eleven track car. The announcement refers to the Elise S Cup that was the company's most recent reveal, but seems to indicate that the Geneva show car will be something different. 19 January 2015 Lotus sales up 54% world-wide for the first nine months of the financial year · 81% sales increase EU overall · 88% increase in UK · 143% increase in France · 139% increase in Germany · 29% up USA; 50% up Canada · 24% up Asia and Middle East · 130% sales increases in China; 125% in Japan · Lotus Motorsport shows 19% increase · 163 dealers, 25 more than nine months ago, 50 more in pipeline by the end of 2015. · Exciting reveal in Geneva Announcing that overall sales are up by 54% in the past nine months provides tangible proof that the forward strategy established by Lotus Cars is working. In volume terms, the increase of 551 cars over the previous year, to a total of 1,565, is an excellent result for the British sports car maker. Lotus has enlarged and strengthened its representation globally, with 25 new dealers enrolled across a number of territories in the past nine months, with another 50 new dealers joining Lotus by the end of 2015.

Lotus CUV sets sights on Macan

The idea of a minimalist sportscar brand like Lotus actually building a crossover, as opposed to its APX concept, is still a bit hard to comprehend. But survival in the modern automotive landscape isn't easy, and a higher-volume model could do a lot to keep the lights on. Hot off the debut of the feather-light 3-Eleven at the Goodwood Festival of Speed, company CEO Jean-Marc Gales is now divulging some more details about the future model. At the moment, Lotus plans to launch the crossover in 2019, and the company has some rather specific targets in mind. "We want to get SUVs to be light and fast. The nearest rival will be the Porsche Macan – but ours will be better," Gales said to Auto Express. Rumors suggest the use of aluminum and composites with the goal for a weight as much as 400-500 pounds less than Porsche's smaller CUV. The model will be exclusive to the Chinese market at launch. While the Lotus crossover is under serious planning, actual development isn't underway yet. According to Auto Express, the company and its Chinese joint venture partner are still waiting for a license to build cars there. Once that comes, they intend to kick things into high gear. Gales also suggested that a Toyota-sourced powertrain, possibly a hybrid, was in the cards.
