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 Evija shown in John Player Special livery at Goodwood SpeedWeek

Goodwood SpeedWeek is here, and Lotus is using the event to highlight the upcoming Evija electric hypercar. Lotus is calling this the car’s “public dynamic debut,” which is relatively true, though the lack of a public audience at Goodwood does put a bit of a damper on the idea. Regardless, the livery used to wrap the Evija is what truly caught our attention. For those familiar with Lotus racing liveries of the past, youÂ’ll immediately recognize it as a modern take on the John Player Special livery. Lotus even photographed the Evija in this livery sitting next to a few old Formula 1 cars wearing the original John Player Special digs. Black and gold just looks proper on a Lotus racecar, and it looks absolutely superb on the Evija, too. Since this is technically a dynamic debut, Lotus also gave us a short video that you can check out below. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. The most intriguing part is the audio. Those electric motors are loud. It canÂ’t come close to matching the yowl of a high output gasoline engine, but the Evija is clearly going to make its own dramatic, electric noise. ThatÂ’s all well and proper, because extra theater is what electric cars typically lack. In an adjacent news brief, Lotus detailed some of the things it did to save weight. Lotus believes that “Colin Chapman would agree the Evija is 100% a true Lotus.” To make it so, Lotus says the carbon fiber monocoque is extremely light, weighing in at just 284 pounds, contributing to making it the lightest electric hypercar when it comes out (not as though thereÂ’s much competition).  Using holes and free space contributed to the lightweighting efforts, too. The venturi tunnels through each rear haunch both save weight and produce downforce. The center console design and floating dashboard leave tons of empty space behind where weight would accumulate otherwise. LotusÂ’ crossbeam design for the dash helps it serve as a structural member and also houses the interior ventilation system, combining two elements into one and saving weight. Lotus says youÂ’ll be able to see the Evija attack the Supercar Run on SpeedWeek, where it will attempt to set a fast lap time against many other new supercars and hypercars. Related Video:

Lotus drops Renault for Mercedes F1 engines

With only three manufacturers supplying engines in Formula One this season, the teams have been fairly evenly split: Ferrari, Sauber and Marussia use Ferrari engines; Mercedes, McLaren, Williams and Force India run on Mercedes power; Red Bull, Toro Rosso, Lotus and Caterham employ Renault power units. But one important team is reportedly preparing to ditch Renault and switch to Mercedes for next year.
That team is Lotus, an outfit which has fallen off its pace the past few seasons but which has still been a vital partner for Renault. That's because until a few seasons ago, the team based in Enstone, UK, was owned by Renault and bore the company's name. The operation was founded in 1981 as Toleman, was rechristened Benetton in 1986, bought by Renault 2000, taking the company's name in 2002, sold to its current owners Genii Capital 2009 and adopting the black and gold Lotus livery in 2011. As Benetton, it ran Ford engines until switching to Renault in 1995, sticking with the French outfit ever since, but that decades-long partnership - which meandered through Renault ownership and back out again - is now apparently drawing to a close.
The departure of Lotus as a customer team ought to allow Renault to focus instead on its increasing ties with Red Bull, which has taken the Enstone team's place as Renault's principal team. It could prove a smart move for the Lotus team as well, as the Mercedes engines have been outperforming the Renault units this season by an order of magnitude: not only is Mercedes far outpacing Red Bull at the top of the standings, but each of Mercedes' customer teams is performing better than Renault's clients.
