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.

Volvo-based, Chinese-built Lotus SUV allegedly due out in 2020

Lotus will set foot in the lucrative SUV segment before the end of 2020, according to a recent report. It's preparing to unveil a high-riding model named Lambda that will be made in China with Swedish parts. Five-plus years in the making, the first Lotus-badged SUV will share its SPA platform with several members of the Volvo range, including the XC90, and with the plug-in hybrid Polestar 1. Citing unverified reports from China, Holland-based AutoWeek reported the Lambda will land in the same segment as the Porsche Cayenne Coupe and upmarket variants of the BMW X6. Patent images (pictured) suggest it will wear a fastback-like roof line. Using the flexible SPA platform will allow Lotus to offer a variety of powertrains, including gasoline-burning four-cylinder engines with forced induction and at least one plug-in hybrid option. SPA wasn't designed to accommodate six- or eight-cylinders, so leveraging electrification will likely be the easiest way for engineers to unlock more performance. An electric variant will reportedly join the range a little bit later in the 2020s. Production will begin in Wuhan, China, in late 2020, according to the same source. Whether the model will be sold in the United States is up in the air. It would make a significant amount of sense: Americans have an insatiable appetite for SUVs, and the company has often stressed it wants to increase its sales in our market. Lotus hasn't commented on the report, and it has remained quiet about its long-rumored SUV. We heard a lot about the model from Jean-Marc Gales, its former CEO; he notably said it will be to the Cayenne what the Evora is to the 911, and he pledged it would become the fastest and most agile model in its segment. He's gone, replaced by Phil Popham in 2018, so that strategy might have changed. If the rumor is accurate, we won't have to wait long to see how Lotus can apply its design language and its unique engineering philosophy to an SUV. Related Video:

Lotus says the electric Evija is a trailblazer that will influence future cars

Lotus, a company known for making nimble sports cars, is stepping outside of its comfort zone to develop a 2,000-horsepower electric hypercar named Evija. Battery technology is heavy, so the limited-edition coupe won't be a featherweight like the Elise, but the firm's chief engineer told Autoblog it will be imbued with Lotus-ness. Keeping weight in check is easier said than done when you're dealing with four individual electric motors and a 70-kilowatt-hour lithium-ion battery pack. Matt Windle, the man in charge of the company's research and development department, explained the widespread use of composite materials like carbon fiber helps offset the mass. He cited clever packaging as another weight-saving measure. The part the steering column is mounted to is also used as a ducting for the HVAC system, for example. "We try to combine many requirements into one part to keep the weight down," Windle said. All told, the Evija (pictured) tips the scale at about 3,700 pounds. That's remarkably light for an electric hypercar, but it's heavier than any Lotus model in recent memory. And yet, Windle assured us it will still feel like a Lotus behind the wheel. That's partly because the battery pack is where the four- or six-cylinder would be in a mid-engined car rather than directly under the passenger compartment. This configuration gives the two passengers the impression of being wrapped in the cockpit while lowering the center of gravity. "We have the ability to deliver the driving dynamics and the performance that customers expect from a Lotus. It's the same dynamic setup, but with a different propulsion system," Windle pointed out. Lotus will initially cap Evija production at 130 examples, so there likely won't be enough units to fill demand, but that's par for the course when it comes to halo models. The numerous lessons learned from the project will trickle down into other models in the coming years, however, and the company has several products in the pipeline. "People do not understand that Lotus is still going. We want them to know we're still here, that we can still innovate," Windle said. "[The Evija] is not just a standalone product. The design language and the content that's in the car will give us direction as we shape future products that are coming. You'll see it as a trailblazer."
