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.

Race Recap: 2013 Korean F1 Grand Prix crazy enough for Psy [spoilers]

The end of qualifying for the 2013 Korean Formula One Grand Prix left us with five pairs: two chassis each from Infiniti Red Bull Racing, Mercedes-AMG Petronas, Lotus, Ferrari and Sauber. Yes, Sauber. The last time the Swiss team had two drivers in the top ten was Japan last year, when Kamui Kobayashi converted the grid spot into a podium.
But let's start at the front of the top ten, where Sebastian Vettel put his Red Bull on pole for the 42nd time in his career. He was followed by Lewis Hamilton in second place by two-tenths of a second, Mark Webber in the second Infiniti Red Bull, and Romain Grosjean in the Lotus in fourth. Out-qualifying teammate Kimi Räikkönen again, the Finn would line up in tenth. Nico Rosberg put the second Mercedes in fifth, Fernando Alonso got the first Ferrari into sixth ahead of teammate Felipe Massa, while Nico Hülkenberg led with the first Sauber in eighth, teammate Esteban Gutiérrez showing the promise he was hired for (okay, and his money) in ninth. Except they'd all move up a place because Webber had to serve his ten-place grid penalty after getting his third reprimand of the season in Singapore. That would get Sergio Perez in his McLaren into tenth. Yes, McLaren needed a grid demotion ahead to make it into the top ten.
It was an entertaining top ten that no one would have expected. When the red lights went out, we were treated to one of the most entertaining races of the year - it was Gangnam Style at 300 kilometers per hour.

New models, new markets: Lotus plans major expansion in the 2020s

Lotus was so quiet during the 2010s that some enthusiasts wonder if it still exists. It's alive, it's healthier than it's ever been in recent memory, and it's orchestrating a major expansion that will put it back in the spotlight. Its renaissance starts with the Evija, an electric hypercar packing a 2,000-horsepower punch that Matt Windle, the company's engineering boss, called a trailblazer. Future models will all be influenced by this limited-edition coupe. Beyond that, the company is taking steps to overhaul its entire business, from the design language that characterizes its cars to the restaurant its employees eat at — seriously. Even the cafeteria is getting a makeover. "We're building the brand, building the product range, building the dealer network, and building facilities. There's a huge investment program going on," Windle told Autoblog. "We need to shoot the arrow far enough ahead so that we don't get stuck in the day-to-day problems and instead keep an eye on what we need to do long-term," he added. The company's to-do list is long, and rebuilding a brand is difficult, but Lotus believes it can pull it off. The executive team is betting on an array of new products to reach customers in markets Lotus has little or no presence in; the United States comes to mind. The ultimate goal is to increase the brand's annual volume. Windle understandably couldn't shed light on the product plan, but unverified rumors point to a born-again Esprit powered by a 500-horsepower hybrid powertrain made up of a mid-mounted, Toyota-sourced V6 and electric components provided by sister company Volvo. Another one of the company's future models is an SUV —its first — allegedly built on Volvo bones and aimed at the Porsche Macan. We hear a new Elise is coming, too. The engineer explained his team doesn't feel the least bit constrained by the decades-long heritage Lotus is built on, and it's ready to embrace new technologies as it moves forward. "Electrification has given us the ability to look at things differently," he explained, while clarifying the company's core values (aerodynamics, ride, handling, and lightweight construction) won't be overlooked as it expands. "We will stay true to them," he pledged. "Light is right," the phrase famously coined by Lotus founder Colin Chapman, will live on, then. China-based Geely purchased a majority stake in Lotus in 2017 and it's helping turn it around.
