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 working on a more spacious daily driver with a kinder price

Lotus has another sports car in the works, with a reveal planned for later this year or early next. It could be the second piece of the puzzle former Lotus CEO Jean-Marc Gales spoke of to Automotive News in 2018, saying parent company Geely "has approved three new models: Two sports cars and the third an SUV." The last new serial production car the English carmaker introduced was the Evora in 2009, the penultimate model in a four-car lineup in the UK that includes the Exige and Elise below, the Evija battery-electric hypercar above. Automotive News Europe writes that the coming sports car will be an "entry-level model" and "provide enough interior space for everyday use," based on an interview with new automaker CEO Phil Popham. Entry-level doesn't mean least expensive, though, rather a price range from GBP55,000 to GBP100,000, which is $68,000 to $123,670 in our money. Those figures would be entry-level here in the U.S., where the sole Lotus is the Evora GT and costs $96,950 before destination. In the UK, the Elise Sport 220 is priced at GBP41,655, the Elise Cup 250 at GBP49,555. For reference, a Porsche 718 Cayman begins at GBP44,790 over there, a Jaguar F-Type at GBP54,510.  The second sports car referenced a couple years ago isn't the Evija, if we can believe last month's report from Autocar. The magazine wrote there's a mid-engined hybrid coupe supposedly evoking the Esprit on the way, scheduled for debut the first half of next year. It will slot in above the Evora, which starts at GBP85,900 in GT410 Sport guise in the UK, and produce more than 500 horsepower with help from a mid-mounted Toyota-sourced V6.  Back to that entry-level car, the most surprising news is when AN writes it is "destined to be the company's last combustion-engine model." That begs the question, what happened to the SUV? Patent images of a Lotus people-hauler leaked in 2017, in 2018 the carmaker said the SUV would hit the market by 2022, and in the middle of last year spy shooters caught what we thought to be a Lotus SUV mule hidden under bodywork of Geely's Lync & Co 01. The AN piece mentioned that "Future options could also include SUV or sporting sedan, according to Popham." But if AN has it right about internal combustion engines, the SUV will be a surprise showing before the entry-level sports car, or will be electric.  And what would the end of ICE-powered models do to the chances of the lightweight revival models Lotus fans want?

2020 Lotus Evora GT Road Test | Don’t forget about Lotus

Slipping into the leather, carbon fiber-backed seats and turning on the engine is an event in the 2020 Lotus Evora GT. Stick the stubby, unmarked key in the ignition, turn two notches; press a button on the remote; push the clutch in, and hold the “Engine Start” button down. The tachometer springs to life, zinging up past 2,000 rpm before settling into an even, but emphatic idle. If everybody wasnÂ’t already staring at the little British sports car in the parking lot, they are now. Once the astoundingly complex, but charming start procedure is done, the fun begins. Lotus has sold only one other more powerful version of the Evora in the United States, that being the GT430. This GT is rocking a poked and prodded version of the Toyota 3.5-liter V6 engine found in all Evoras, but as in some other versions, an Edelbrock supercharger has been added to boost output. With the six-speed manual, its output is 416 horsepower and 317 pound-feet of torque. Twist increases to 332 pound-feet with the six-speed automatic, but donÂ’t buy a Lotus with an automatic. Just donÂ’t do it.  The gear lever snicks into first with positive, notch-like action. LotusÂ’ analog gauges stare back, displaying the most important information in a legible size and font. ThereÂ’s a digital speedometer tucked into a little nook under the steering wheel's red center line, just the right height for a quick glance downward. Grippy leather covers the 9 and 3 positions on the wheel, while soft Alcantara contrasts with the leather on the top and flat bottom of the wheel. Lotus clearly knows that sweaty racetrack hands and Alcantara donÂ’t mix.  This clutch is heavy, is the first thought upon setting out on the road. It fits the car and makes the driver work a little to be smooth. Good. Driving a Lotus shouldnÂ’t be a walk in the park. The driving position is bang-on. Those manually-adjustable (and heated!) leather seats are mounted low, their bolsters large enough to be snug, but short enough to slip over getting in. The view forward doesnÂ’t leave much to be desired, but looking out the back is like looking through a mail slot. ThereÂ’s a tiny box of glass, but itÂ’s tinted, making it difficult to see whatever might be visible. Side mirrors it is, and those are plenty fine, even allowing a view of the wide rear hips.  At speed, racecar vibes abound instantly.
