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 supercar officially named Evija

Only known as the Type 130 to this point, the new Lotus supercar finally has its official name: Evija. Lotus made the announcement at the 2019 Goodwood Festival of Speed, and some fans have the lucky opportunity to get a sneak preview of the all-electric performance vehicle during the event. The Evija, which is pronounced "ev-eye-a," will be the first car Lotus has produced under the ownership of Chinese umbrella company Geely. Evija means "the first in existence" or "the living one," according to Lotus, thought the company did not go into the origins of the word. With cars such as the Rimac C_Two already in existence, the Evija is not the first electric supercar, but Lotus says it is the "first all-electric hypercar" from a British automaker. It's also the first electric Lotus. The Evija is slated for its world debut in London on July 16, 2019, and production is expected to start in 2020. However, Lotus set up a light show experience at Goodwood that involves that car. So, fans won't see the full vehicle, but the experience will tease small yet-to-be-seen details.  Very little information is known about the car yet, save for a nebulous aero image and a couple short video teasers. It will have a push-button gear selector, a light-up rear Lotus badge, an electric charging dock cover, and it appears it will have a tablet style dash setup. And, of course, carbon fiber will be the material of choice inside and out. We'll have full specs, photos, and information shortly. Auto News Green Green Lotus Lotus Evija

Lotus Motorcycles C-01 now 'ready for the road'

When we first laid eyes on leaked images of the Lotus Motorcycles C-01, we wondered if its laid-back, sport cruiser shape was really appropriate for a motorcycle bearing any connection with Colin Chapman and the company's famous "add lightness" mantra. We've now seen official pictures of the bike in multiple color schemes, including classic black and gold, British racing green and even a variant that resembles Martini livery, and while we think it looks pretty cool, our opinion hasn't really changed.
Perhaps we shouldn't be surprised that the C-01 isn't an embodiment of the Lotus ethos, as the company that intends to build it isn't really Lotus at all, its builders - German racing firm Kodewa and tuner Holzer Group - merely having licensed the name of the British sportscar maker. It was designed by Daniel Simon, who once worked for Volkswagen and consulted for Bugatti and is the man credited with creating the reborn Tron Light Cycles. Still, looking past its questionable heritage, the C-01 looks pretty darn awesome, and there are some interesting bits that have us looking forward to the production version that's reportedly due within the next two months.
As expected, power comes in at 200 horsepower, courtesy of a modified version of KTM's 1,195-cc V-twin engine. The chassis is made up of steel, titanium and carbon fiber, with a seat height of about 28 inches. Its wheelbase, at about 65 inches, is a full 10 inches longer than a real street-legal superbike, and its front end is raked way out in front with a 19-inch wheel. Those dimensions mean we shouldn't expect much racetrack prowess, unless its rider is only planning on going in a straight line. Indeed, with a claimed dry weight of under 400 pounds, the Lotus Motorcycles C-01 ought to be mighty quick down the quarter mile.
