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 Eletre opens a new front in electric SUVs

Ladies and gentlemen, the new era of Lotus as an EV maker begins with this, the Eletre. It takes elements we've seen on the Evija battery-electric hypercar and Emira ICE sports car, wraps them in a larger package, jacks them up, and throws in a lot of new tech for the brand and the market. Let's start with size, which is the easy bit. The Eletre is 201 inches long on a 118.9-inch wheelbase, about 79 inches wide, and 64 inches high. Every one of those dimensions puts the Lotus within a couple of inches of the Aston Martin DBX: the EV being a little longer, with a slightly shorter wheelbase, a little wider, and a roof a couple of inches lower. For us, the side view most closely represents the form we had in mind based on recent spy shots. The front is intense, the yellow of the hero car making the greatest contrast with the polygonal void below. The lights above the leading edge are DRLs and turn signals, the main beams are recessed into that void, hugging the upper edge. The rear, with its Lotus script and full-width light bar fading into triangular intakes along the sides, clearly comes from the sports cars. It can glow in four colors depending on what it needs to communicate, and forms a connection with the light bar across the instrument panel. The SUV proportions and black roof are still playing tricks with our eyes, though; we can't help feeling the Eletre carries its bulk up high. The wheels are an optional set of 23-inchers that hide optional 10-piston (ten!) calipers gripping ceramic composite rotors. Lotus isn't ready to divulge specific battery capacity and motor outputs between those wheels. All we're told is the pack is more than 100 kWh and output starts at 600 horsepower. Every Eletre is all-wheel-drive, with a motor on each axle. The 800-volt electrical architecture can handle up to 350-kW fast-charging, 20 minutes at a station at that charge rate restoring 248 WLTP miles of the Eletre's estimated 373-mile range in WLTP testing. EPA numbers will come eventually. Lotus says the hauler will get to 62 miles per hour in under 3 seconds and hit a top speed of 161 mph. The electronic side mirror housings each contain three cameras, one camera for the rear views, one to help stitch a 360-degree overhead view, and one to help enable self-driving. The charge port is on the front left fender, but keen eyes might notice more shutlines atop the front wheel arches.

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.
