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 Esprit spied wearing mismatched Evora bodywork

The sorta funky looking Lotus Evora you see above isn't really an Evora at all. In fact, it's a mule for an upcoming new Lotus in the spirit of the Esprit, which, rumor has it, will be introduced in the first half of 2021. It may even be called the Esprit, reviving the name of one of the company's most recognizable and well-loved nameplates, though that has yet to be confirmed by the British automaker. Power is expected to come from a Toyota-sourced V6 engine, as is the case with the Evora. But instead of the Evora's 2+2 seating configuration, the reborn Esprit would be a two-seater. While we aren't privy to the automaker's engineering offices, it seems the space vacated by the vestigial rear seating area might be used to hold some battery packs, as the upcoming car is going to be a hybrid. The 2020 Lotus Evora spins 416 horsepower out of its supercharged 3.5-liter V6; the hybridized Esprit is rumored to pack over 500 ponies, buoyed by an electric motor and lithium ion battery pack that's thought to be cribbed from the Volvo parts bin. That makes sense, as Lotus and Volvo both fall under Chinese automaker Geely's umbrella. The Evora offers the choice of six-speed manual or automatic gearboxes, but we'll have to wait and see if those choices are shared with the Esprit. The mule seen above is sporting some mismatched Evora bodywork — seemingly sprayed black in haste, judging by the specks of blue and yellow at the front and rear along with the lone green pop just ahead of the rear wheels — that has been widened with some tacked on wheel arches. The production version is expected to crib styling elements from Lotus' range-topping electric Evija. We can't wait to see how it all turns out. Related Video:

Lotus offers Exige S Roadster for sale, but not in North America

The first thing you need to know is that this is the Lotus Exige S Roadster, unchanged from the Exige S even in price and officially the fastest convertible Lotus has ever made. The second thing you need to know is that if you live in the US, you won't be getting this car.
Now that that's out of the way, the lack of a roof, rear wing and front splitter help make it 22 pounds lighter than the coupe, coming in a 2,565 pounds, and the supercharged 3.5-liter V6 in this topless blossom discharges 345 horsepower and 295 pound-feet of torque. For historical comparison with a non-convertible, those numbers nearly match the 2004 Lotus Esprit V8 Final Run edition - which had twin Garrett turbochargers. Yet the Exige S gets from a stoplight to 60 miles per hour in 3.8 seconds, nearly a full second quicker than that Esprit. Fair play, though, the Esprit did weigh 3,040 pounds.
It will be fitted with a six-speed manual only, and cost 52,900 pounds ($79,667 US), 55,378 euros ($71,404 US) or 8,500,000 yen ($82,078 US), depending on where you live. Here in the US we'll be sticking with the track-only Exige V6 Cup and Cup R models. The press release below offers more on the fine points.
