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 will kill Elise, Exige and Evora to make room for the new Type 131

Lotus ended years of speculation by announcing it will begin rejuvenating its range when it releases a new model in 2021. Known as the Type 131 internally, its arrival will mark the end of the Elise, the Exige and the Evora. Although the three aforementioned models are showing their age, putting them out to pasture at about the same time is a surprising move because they're currently the only cars in the company's lineup. Saying that the Type 131 will have big shoes to fill is an understatement; it will blaze the path that a full family of new cars will follow. Official details about the 131 are few and far between, but an earlier report sketches the outline of a driver-friendly sports car powered by a mid-mounted engine. While it won't stray far from the lightness and the nimbleness that Lotus is famous for, it will be equipped with more tech than even the Evora, which offers a more comprehensive list of features than the track-inspired Exige and the back-to-the-basics Elise. Insiders have claimed that the 131 will be built on a new modular platform, and that it will not use any kind of electrification. Lotus released an image that shows the Evija (an electric, 2,000-horsepower halo car strictly limited to 130 units globally) next to three enigmatic cars hidden by a cover; one is presumably the 131. Another might be the battery-powered model that it's developing jointly with Renault-owned Alpine. As for the third, your guess is as good as ours. We know that the British firm is developing a Volvo-based SUV, but it's not pictured in the lineup. News of a new Lotus model will bring joy to enthusiasts and economists alike. The company is investing over 100 million British pounds (about $136 million) into its Hethel, England, facility, and it will hire about 250 employees to bring the 131 to the market. Most of the recruits will work in engineering and manufacturing. Lotus noted that it hopes to start building prototypes of the Type 131 — an internal designation that will likely not appear on the production model — in 2021. We don't know if deliveries will also begin this year, or if they are scheduled to start a little later. Regardless, it will be worth the wait. Lotus told Autoblog that all of its future cars will be engineered for global markets, and that its intention is to sell the Type 131 in North America. Related video:

Lotus electric sedan due in 2023 to take on Porsche Taycan

Lotus took a massive step towards the mainstream when it released the Eletre (pictured above), an electric crossover developed with volume in mind. It will continue walking in this direction by launching its first sedan, and a recent report suggests the model will be aimed at the Porsche Taycan. Known as the Type 133 internally, and referred to as a four-door coupe, the sedan will join the firm's portfolio of so-called "lifestyle" EVs. It will borrow some styling cues from the Eletre (pictured above) but it won't be merely a scaled-down crossover. "There has to be some continuity and family identity," explained Peter Horbury, Lotus' senior vice president of design, in an interview with British magazine Autocar. "Families aren't made up entirely of triplets or quadruplets. Every member of a family can have their own character," he added. While the Type 133 — a name that won't make the leap to production; the Eletre was called Type 132 — won't be as basic as, say, an Elise, it will be positioned as a driver's car. Gavan Kershaw, Lotus' director of attributes and product integrity, told Autocar that the engineering team benchmarked the Porsche Taycan during the Eletre's development process and the lessons learned will be applied to the Type 133. Like its taller sibling, the sedan should feature a long list of technology features, including an air suspension system and rear-wheel steering. Powertrain specifications haven't been released yet, but the fact that the Eletre and the Type 133 will be closely related underneath the sheet metal gives us some idea of what to expect. Power for the first Lotus crossover comes from a pair of electric motors that zap the four wheels with around 600 horsepower. The battery pack's capacity checks in at over 100 kilowatt-hours, and an 800-volt electrical architecture enables fast-charging technology. Lotus pegs the Eletre's maximum driving range at 373 miles on the testing cycle used in Europe. It's reasonable to assume that the sedan, which should be lighter and more aerodynamic, should be capable of going further on a charge. Lotus is expected to unveil the Type 133 in 2023. The model will be built alongside the Eletre in Wuhan, China. Related video: This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.
