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 Type 130 electric hypercar confirmed for July 16 reveal

Lotus just formally announced that its electric hypercar will be revealed on July 16. It's called the Type 130, and it's confirmed for production at Lotus headquarters in Hethel, Norfolk. The name is derived directly from the production quantity, as Lotus is capping the car at just 130 units. This project is coming together at a rapid pace, as Lotus also says the first customer deliveries will happen in 2020. Meeting time goals for the production of EVs has proven troublesome for some manufacturers, so we'll see if Lotus is able to deliver in the next year and a half. The British sports car company has Chinese backing in the form of Geely now, so the funds to make this car happen appear to be there. Lotus says that it's had several hundred people express interest in buying the Type 130 since its confirmation at the Shanghai Auto Show. Of course, with only 130 slots available to buy the vehicle, we'll see how it all shakes out once Lotus announces what we expect will be an extravagant price tag. Hypercars, and especially electric hypercars, are never cheap. Lotus released a teaser photo that tells us next to nothing, but it is a photo of the car. The teaser video below is a bit more interesting with the "Hand Built in Britain By Lotus" emblem and the electric charge port hidden off to the left. It has an automatically closing door there, which doesn't exactly feel like Lotus' style. If something can be done mechanically to save weight, that's typically the path taken. We won't prejudge the car too harshly, though, as this represents an entirely new take on Lotus vehicles. This content is hosted by a third party. To view it, please update your privacy preferences.

2020 Lotus Elise Classic Heritage Editions celebrate past race car liveries

For 2020, the Lotus Elise is getting a very limited edition. The Elise Classic Heritage Edition is a version that can be had in one of four liveries that reference past Lotus race cars. While the paint schemes are fitting tributes, the redundancy of having "Classic" and "Heritage" in the same name seem antithetical to Colin Chapman's philosophy of "simplify and add lightness." Name aside, the color schemes look good. Naturally, one of them is the famous black and gold of the John Player Special Lotus race cars. Others are less familiar, but still significant. Two of them highlight cars driven by famous racers. The blue, red and silver combo references the 1980 Lotus Type 81 driven by Mario Andretti, Nigel Mansell and Elio de Angelis. The red, white and gold version is for the 1968 Type 49B driven by Graham Hill. As for the blue and white car, it celebrates the first Lotus F1 car to win pole position and the race, the 1960 Type 18. The flashy paint is matched with equally flashy interiors. The upper door panels and other trim pieces are painted in coordinated colors, and the seat centers are finished in matching fabric. The one exception is the blue and white model that gets red seats. While the car is based on the 217-horsepower Elise 220, it gets features that are normally extra-cost on that car, including air conditioning, cruise control, a radio, carpeting and floor mats, two-piece brake rotors and forged wheels. Available as options are a hardtop, lithium-ion battery and titanium exhaust. All of these extra features, plus the colors and exclusivity help make the extra GBP6,350-pound upcharge worthwhile, which makes the car cost GBP46,250, or just over $57,000 at current exchange rates. Speaking of exclusivity, only 100 of these cars will be sold internationally. Lotus notes that the split between the different colors will be dependent on demand, so certain liveries could be rarer than others. Don't expect any of them to be offered in the U.S., though, since the Elise isn't available here at all. Related Video:
