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.

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.

Lotus is building 60 extra light, extra aerodynamic Exige Cup 380s

Lotus is never done adding lightness and once again turned its attention to the Exige. Like so many other special Lotuses, this one, called the Exige Cup 380, makes the same 375 horsepower from its supercharged 3.5-liter V6. However, the weight savings is a significant 117 pounds compared with the 2,447-pound Exige Sport 380. This savings comes from the inclusion of many carbon-fiber parts including a one-piece rear hatch, side intakes, hood, front splitter, side sills, and seats, among others. Lotus also removed the gas struts for the hatch to save 2.2 pounds. And if that's not enough, you can save another 2.2 pounds by choosing the optional HVAC and air vent surrounds, and 22 pounds with an optional exhaust system. The Exige Cup 380 also produces significantly more downforce than the Sport, 43-percent more to be exact. That results in maximum downforce of about 441 pounds at the Cup 380's top speed of 175 mph. The car achieves this thanks to a revised front bumper and splitter, vents above the front wheels, more vents behind the rear wheels, and a new rear wing. Even the windshield wiper rests in a vertical position to aid aerodynamics. The Cup 380 doesn't just benefit from better aerodynamics and less weight. The rear tires are wider than the Sport 380 at 285 mm. The Cup 380 also has two-way adjustable shocks and adjustable front and rear anti-roll bars. Even the stability control can be adjusted to the driver's needs. The car is stopped by four-piston brake calipers at all four corners, and a standard steel roll bar protects the driver. If owners wish, they can also add an FIA-certified full roll cage. Lotus will only build 60 of these Exiges, and they're only available in Europe. They're not cheap either. In the UK, buyers will spend GBP83,000 in the UK and ˆ109,900 in Europe. That means this Exige would cost between $106,000 and $118,000, at current exchange rates. Related Video:
