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 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.

Turns out the 2020 Lotus Evora GT is one of the best sounding cars on sale

Toyota has built plenty of engines that sound the business. We know the company has it in them, but what comes out isn’t always enthusiast-focused. Yet, hereÂ’s a fairly normal Toyota 3.5-liter V6, sitting in the middle of a Lotus. YouÂ’ll find it under the hood of a Toyota Camry, but here it is sitting under the engine cover of this 2020 Lotus Evora GT. Of course, Lotus hasnÂ’t dropped the engine in there without Lotus-fying it. This one has an Edelbrock supercharger with an integrated water-to-air charge cooler, plus a special calibration and tune from Lotus. In the Toyota, the base engine makes 301 horsepower. This Evora GT is putting out 416 horsepower and 317 pound-feet of torque. It also breathes through a set of pipes that the Brits would call ace. Check out the video at the top to get a taste of what we heard for a week straight. Our Evora GT was equipped with the standard exhaust. ThereÂ’s an optional titanium exhaust that drops 22 pounds from the curb weight, but Lotus says that it doesnÂ’t actually sound all that different. What does make a difference in the sound is changing the drive mode. ThereÂ’s a valve that opens in the exhaust when you select Sport mode or press the exhaust button. This drastically changes the sound heard from the cabin. In normal Drive mode, the exhaust is muted and just hanging out in the background. ItÂ’s shockingly quiet, but perfect for highway cruising because the drone goes away. Sport mode completely changes the tone and unlocks a sweet wail we didnÂ’t know the Toyota V6 had within it. ThereÂ’s no computer-enhanced or synthesized noises to be heard here. ItÂ’s all real. Taking it one step further in Race mode unlocks the tiniest bit more noise, Lotus says, but itÂ’s hardly noticeable in practice. We found the best experience was in Sport mode, since that reigns in traction control, retains stability control, and boosts throttle response by a bit. 2020 Lotus Evora GT View 6 Photos Under tunnels and overpasses — and this does feel weird to say, knowing the engineÂ’s origins — thereÂ’s a hint of Formula one car sound in there. WeÂ’re talking F1 from a few years ago, not the boring turbo engines of today. The way it shrieks and screams off walls, completely immersing you in the echoing sound, is intoxicating. Very few cars can match the Evora in sound quality, and thatÂ’s impressive considering some of the noisemakers car companies put out these days.
