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.

Behind the scenes of Lotus' spectacular truck-over-F1 jump

A Lotus F1 car and the truck in which it's transported may both be powered by Renault and share a common JPS livery, but as far as size and performance are concerned, they're at opposite ends of the spectrum. So if you had to jump one over the other, you'd think it'd be a no-brainer to skip the single-seater over the tractor-trailer. Right? Well that may be the more logical conclusion, but it's not the way the Lotus team and its technology partner EMC decided to go for this latest promo. Instead they jumped the semi over the grand prix car. The stunt was obviously geared towards publicity, but while they were at it, they set a Guinness World Record for the longest truck jump at 83 feet, 7 inches. The previous record, according to Guinness, stood at 50 feet, 6 inches, and was set on MTV's Nitro Circus on November 17, 2008, by Gregg Godfrey at Rocky Mountain Raceway in Salt Lake City. That record stood for six years, but (as best we can tell) was set without the trailer attached, or the F1 car tracking underneath - which only makes this latest stunt that much more impressive. You may have seen the promo clip circulating the interwebs late last week, but we've included a making-of video below as well to show how the stunt team managed to pull it all off.

Lotus teases its sleek Type 130 electric hypercar

Lotus has shown a teaser image of a new concept, which will usher in the automaker's electric era. The Type 130 hypercar concept will be shown later this year in London, but this aerodynamic teaser is the first glimpse at its shapely flanks. The Type 130 is said to be in "advanced stages of development." According to Lotus, the Type 130 will spawn a production version, which will be the brand's first all-new vehicle in 11 years. It will be partially bankrolled by Lotus' parent company, the Chinese carmaker Geely, which also owns Volvo. Despite that, the hypercar will not be built in China, but in England. An earlier Autocar article estimated the eventual price at around $2.6 million. Last month, news broke that Lotus is also bringing another new car to market, but that one is likely to retain internal combustion technology along with engineering ties to older Lotus architecture, as it forms a sort of "bridge" between current Lotus products and its future cars. Hence, it can't be called "all-new" in the same sense as a fully electric halo model can. Lotus also noted some of its "firsts" when informing the media of the upcoming concept, which it calls "the world's first full-electric British hypercar." The 1995 Elise was the world's first aluminum and bonded extrusion construction production car, while the 1957 Elite was a production first in the sense that it first brought the composite monocoque within the reach of customers. Between those, there was a lot of groundbreaking F1 knowhow: ground effects for the '77 Type 78 F1 car, carbon fiber for the '81 Type 88, and active suspension in 1983.
