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 Emeya electric sedan revealed like a sleeker Eletre

The number of four-door models in the Lotus line has doubled with the reveal of the Emeya electric sedan. Not surprisingly, it looks very much like the Eletre SUV, just lower and sleeker. The yellow and black debut color just emphasizes that fact, too. What is a bit surprising is the surprising lack of concrete details on the car. We really do mean it when we say this looks like the Eletre. The Emeya utilizes almost the same lines at every point, from the pointy, angry nose to the curvy flanks. But on the whole, the lower height and less overall visual mass makes it a much more successful design. It also adopts the active grille shutters, diffuser and rear spoiler like the Eletre. One thing that does differentiate the exterior of the Emeya is the use of dual running lights on each end of the front fascia. The Emeya's interior again is a near carbon copy of the Eletre's. A single screen is the focal point with an angular dual-cowl dash board surrounding it. A small screen is nestled in the dash behind the steering wheel to provide basic driving information. Extensive use of leather and faux suede is featured throughout. Specifications on the Emeya are lacking detail. It will be available in a dual-motor all-wheel-drive configuration that can reach speeds topping 155 mph. The motors will also get it to 62 mph in a claimed 2.8 seconds. It can take advantage of 350-kW-capable fast chargers, as well. The whole car also rides on an adaptive air suspension. But actual horsepower, torque, battery capacity and much more haven't been given.  The Emeya will go into production sometime next year. Naturally, pricing hasn't been announced, either. Being smaller than the Eletre, it may end up being a bit less costly. Stay tuned for more of that information closer to production. Related video:

The time Elon Musk paid $1 million for James Bond submarine car that cost a couple $100

Tesla CEO Elon Musk landed himself in court after insulting a diver who criticized his plan to rescue a Thai soccer trapped in a cave using a purpose-built mini submarine. Which reminded us that Musk's interest in submarines started years ago. The story begins in 1989, when a couple from Long Island put every barn-find hunter to shame by paying $100 for a locked storage unit, and cracking it open to find a 1976 Lotus Esprit buried under a pile of blankets. That's a cool find, the S1 Esprit is sought-after among enthusiasts, but CNBC reported they quickly learned their car was modified to star in the 1977 James Bond film "The Spy Who Loved Me." Ignoring Colin Chapman's "light is right" motto, the producers alchemized the Lotus into a fully functional submarine by welding in the wheel arches and the underbody, and adding winglets for more stability. Four propellers powered by a battery pack housed in the cabin moved the Esprit under water, and the coupe gained front-mounted missile launchers. The modifications reportedly cost $100,000. The couple had never seen a James Bond movie; they likely assumed it was a mad scientist's kit car, or a science fair project gone wrong. The $100 purchase price represents about $207 in 2019 dollars, so the unsuspecting buyers could have easily sold it as a parts car, made a small amount of money on it, and ended up with a free storage unit. However, they became aware of the Esprit's significance in Hollywood history when truckers identified it over CB radio while they were hauling it home. lotus-esprit-submarine-in-action-1 View 3 Photos They weren't collectors, and storing a submarine is terribly impractical, so they commissioned a cosmetic restoration and asked auction house RM Sotheby's to sell it in 2013. An enigmatic buyer paid $997,000 for the non-running movie prop. Musk later revealed himself as its new owner. "I was disappointed to learn that it can't actually transform. What I'm going to do is upgrade it with a Tesla electric powertrain, and try to make it transform for real," he announced. Even billionaire-owned project cars sit for longer than planned, and there's little evidence the Esprit is in swimming condition, let alone capable of morphing into a submarine at the simple push of a button. If it could, we're certain Musk would have hyped it up on Twitter. But while stalled projects normally draw the ire of loved ones as they take up garage space, Musk's turned into a well of inspiration.
