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 supposedly working up a new Elan, again

Geely's investment in Volvo, and giving Volvo the freedom to do what Volvo knows how to do, propelled the Swedish automaker to another level. This could be the year English automaker Lotus begins the same climb. Late last year, Bloomberg said Geely committed an initial $2 billion to the Lotus renaissance. That number was low, the Financial Times reporting Geely planned to invest billions over the next five years. In May this year, Lotus announced it was hiring 200 new engineers and opening a new engineering center to develop a new range of SUVs, GTs, and sedans that would expand consumer appeal to triple its current annual volume. Sports cars are a vital part of the new mix as well, Autocar citing Lotus insiders for a report that a new Elan convertible sports car has "a strong possibility of being revived in the next few years" as a nameplate.    Lotus made a splash about bringing back the Elan — along with a new Esprit, Eterne, Elise, Elite, and city car — at the 2010 Paris Motor Show. That was a very different Lotus, when Malaysian automaker Proton owned the English outfit and ex-Ferrari marketing honcho Dany Bahar manned the helm. In spite of promises of funding, the team at Hethel lurched through years of corporate drama and dire finances until Geely took over in 2017. The latest Elan whispers sketch a convertible targeting the Porsche 718 Boxster - Lotus in general has Porsche in its sights. The car pictured above is from the first re-animation of the Elan badge, from 1989 to 1995. A coming Elan would sit above the Elise in the lineup, with more space, amenities, and luxury, at the same time as it would focus on being the lightest and most agile in the segment. Before that arrives, however, Lotus needs to finish developing the sports car platform that will help carry the brand's new range for the next decade; The Lotus SUV uses Volvo's SPA architecture that carries the XC90 and XC60. CEO Phil Popham's Vision-80 program — which now seeks to grow annual volume not merely triple but six-fold to 10,000 cars by 2029 — will be centered around the multi-material architecture that replaces the Elise and Evora architectures presently employed. Due in two years, the rivet-bonded "alloy-core" chassis will likely include carbon fiber and other advanced materials.

A Lotus Super Seven shows what simple beauty means

Roadgoing sports cars don't get much more pure than the Lotus Seven. With no roof or luxuries of any kind, this is quite possibly the car that exemplifies better than any other Lotus founder Colin Chapman's ethos of "simplify, then add lightness." Geoff Wise owns a 1963 Lotus Super Seven, and he shows why the car's uncluttered layout works so well, as you'll see in Petrolicious' latest video. Petrolicious often profiles people who take a classic car and upgrade it into a vintage racer one piece at a time. Wise did the exact opposite, though. He bought his Seven as a track car and converted it to work better on the road. For example, the engine now runs on pump gas, but it still has plenty of power. The bored and stroked 1.7-liter four-cylinder has a claimed 120 horsepower, which is more than adequate in the 1,000-pound Lotus. Wise says the Seven gets tons of attention when he goes for a drive, especially from kids. It's easy to understand why. In a world of crossovers and active safety systems, seeing a car that's so basic is transfixing. Enjoy watching the little Lotus on the road in the latest clip from Petrolicious. If you don't have the space for one in the garage, there's at least the option of the upcoming Lego kit for your bookshelf. Related Video:
