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.

Lotus unveils new racing bike for British Olympics team

Lotus Engineering, the automotive consultancy and industrial design arm of the British performance car brand, has marked its return to competitive cycling with a sleek and lightweight new track bike that features novel fork, seat stays and handlebars. Developed in concert with Hope Technology, a British bike-components manufacturer, the bike is aimed at helping the Great Britain Cycling Team notch medals at the 2020 Tokyo Olympics. For Lotus, the bike represents a return to cycling after a 25-year absence. It’s also a nod to the Lotus Type 108 bike Chris Boardman rode to a gold medal at the 1992 Barcelona Olympics and in the 1994 Tour de France, where he won the prologue time trial to take the yellow jersey. Hope/Lotus British Cycling View 10 Photos WeÂ’re not given any details about the bikeÂ’s technology or specs, except that the Hope-designed frame is made of high-modulus composites with fabric woven in the U.K. Lotus was responsible for the unique fork and seat stays, with each characterized by slim polished metal tubing and a wide-flaring hooping design when viewed straight on. The handlebars similarly feature a flattened profile across the crossbar. Not surprisingly, the bike underwent lots of wind-tunnel testing, both with and without riders, plus testing to maximize strength with minimal weight. Lotus also said it worked to improve stiffness and front end feel. Much of the design and development was done after the 2016 Olympics, when the UCI governing body made changes to the rules governing bike development. Lotus and Hope were supported by British engineering firm Renishaw. The bikeÂ’s design must be approved by the UCI and be ridden by the Great Britain Cycling Team during the 2019–2020 Tissot UCI Track Cycling World Cup series by the end of this year in order to qualify to be ridden in the 2020 Olympics in Tokyo. TheyÂ’ll start riding it this weekend at the Minsk-Arena velodrome in Belarus, and November 8–10 in Glasgow, Scotland. ItÂ’ll also be displayed at the Rouler Classic event in London starting Friday and running through Sunday. Lotus Bicycle lotus engineering
