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 Evora GT410 Sport exhaust is the best new holiday song

No matter what holidays people are celebrating, there's one winter celebration car enthusiasts can come together for: Driftmas. A Lotus Evora GT410 Sport was recently possessed by the ghost of Driftmas present Ken Block and decided to get sideways all over the Lotus campus in Hethel, Norfolk, England. The result is a beautiful winter symphony. The video is done in a slightly cheeky manner, as the yellow Evora shows up to work with a fully geared-up driver in the front seat, and a full Christmas tree stick to the rear engine cover. After blowing past a pristine Espirit S1 in a "slow" zone, the Evora slowly creeps through one of the garages, where a beautiful black and gold Type 72 race car sits quiet as a mouse. It then makes its way through a testing area and to a parking lot, where it rings a few bells around three specialty Lotus models, including what appear to be Exige Cup cars. It finishes the ride in front of the main office, where Lotus has another Christmas tree filled with little toy cars as ornaments. Before the Grinches start complaining about how it's not Gymkhana, that's correct. It's not. But we'd never turn our noses at a video with a soundtrack a sweet as this. Merry Driftmas to all.

Lotus Advanced Performance division wants to make your dreams come true

Lotus took a big step in its quest to position itself as a British alternative to Porsche by launching a division called Advanced Performance. Run by a former Aston Martin executive, Lotus Advanced Performance will design and build one-off and few-off models, among other tasks. Most high-end and specialty carmakers operate a program that gives customers some degree of freedom in terms of customization. Lotus was, until now, largely an exception to this rule. It hopes to make up for lost time by giving its Advanced Performance division a surprisingly long list of responsibilities. First the department will be responsible for building "ultra-exclusive and unique vehicles" that will not be part of the firm's regular-production line-up. One of these (shown in a sketch above) looks like it draws inspiration from classic Formula One cars. Details are few and far between, but the massive rear wing speaks volumes about the kind of halo cars we'll see in the not-too-distant future. What's unclear is whether Lotus will take customer requests. We've reached out, and we'll update this story if we learn more. Designing limited-edition models and developing race cars will also fall within the scope of Advanced Performance's responsibilities. And, it's the door that buyers who want to customize their car will need to knock on; they'll be able to select different paint colors, trim materials, and upholsteries. Optional extras and a range of Lotus-branded accessories will also emerge from Advanced Performance's headquarters. Immersing customers and enthusiasts into the Lotus world is important as well, so Advanced Performance will organize tours of the brand's production lines, organize driving academies around the world (including on the Hethel test track in England) and prepare "money can't buy" opportunities for clients. There's no word yet on what these experiences will look like; more information should emerge later in 2022. Lotus put Simon Lane in charge of its Advanced Performance division. He's a good choice: his resume includes leading Aston Martin's Q division, whose list of responsibilities looks a lot like Advanced Performance's. Q notably brought us the V8-powered Cygnet in 2018 and the one-of-a-kind Victor unveiled in 2020. Some of its other projects have been more tame: it gave the DBX a long list of carbon fiber parts.
