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.

Editors' Picks June 2024: Some German SUVs and an excellent sports car

This month sees some recently-refreshed luxury SUVs join the list of Editors' Picks. Both the BMW X5 and Porsche Cayenne are fresh for 2024, and both are extremely tempting luxury performance SUVs for the well-off buyer. The vast array of powertrains available for both of them ensure there's a version for all comers, and any enthusiast would adore the extra-high-performance versions of both. Of course, enthusiasts will enjoy the last car on this month's list the most with the Lotus Emira. It's simply spectacular to drive, and we can't recommend it enough to the hardcore driver. In case you missed previous Editors' Picks posts, here’s a quick refresher on whatÂ’s going on here. We rate all the new cars we drive with a 1-10 score. Cars that are exemplary in their respective segments get an EditorsÂ’ Pick designation. Those are the ones weÂ’d recommend to our friends, family and anybody whoÂ’s curious and asks the question. You'll find the entire list of Editors' Picks at this link here, which we keep updated as cars are either added or dropped from the list. The vehicles youÂ’ll find below consist of every car we rated in June that earned an EditorsÂ’ Pick. 2024 BMW X5 2024 BMW X5 M Competition View 41 Photos Quick take: The X5 is most desirable in its PHEV and M60i V8 trims, but the whole lineup is extremely competent and brings together excellent performance, excess luxury and cutting-edge tech for its segment. Score: 7.5 What it competes with: Mercedes-Benz GLE, Porsche Cayenne, Range Rover Sport, Maserati Levante, Genesis GV80, Audi Q8 Pros: Superb to drive with knockout powertrains; excellent utility and creative features; styling is sporty and attractive but not over the top Cons: Infotainment system can be a pain; M Competition model is a little over the top; gets pricey quick with options From the editors:  Senior Editor, Electric John Beltz Snyder — "I really like the dual-opening liftgate/tailgate combo. The liftgate portion up top opens quickly, allowing you to throw something inside or grab something out of the back. Flipping down the lower tailgate part gives you a nice place to sit and change shoes. Another benefit is that you can open the liftgate without unsecured items immediately falling out. And with the way the X5 M Competition encourages you to drive it hard, you will end up shifting loose cargo around at some point." Road Test Editor Zac Palmer — "I'd snag the X5 M60i out of all the various X5 variants.

Lotus signs joint venture agreement with China's Goldstar

Lotus and China's Goldstar Heavy Industrial Company are forming a joint venture that will bring the historic British sports-car maker into the country. "The collaboration seeks to accelerate the development of Lotus cars in the premium sports segment in China," according to the announcement. The JV will include research projects on efficient and advanced technology, and ultimately lead to sales of cars there, Lotus said. China's auto market is no longer experiencing the double-digit growth of the past, but it still continues to expand. Meanwhile, Lotus saw sales jump 55 percent in the last fiscal year and it opened 36 new dealers, according to CEO Jean-Marc Gales. The joint venture announcement also hints at the possibility of Chinese-made models, but it shouldn't dilute the brand. Lotus is clear that core vehicles like the Evora, Exige and Elise would remain exclusively in production at the headquarters in Hethel, England. Just a couple years ago, Lotus appeared to be on its deathbed after losing a quarter of its workforce, but since that setback the company has started to crawl back. PROTON, LOTUS GROUP AND GOLDSTAR SIGNED JV AGREEMENT KUALA LUMPUR – PROTON Holdings Berhad ("PROTON") the ultimate holding company of Lotus Group, announced that it has signed a Joint Venture ("JV") Agreement with Lotus Group International Limited, United Kingdom ("Lotus Group") and Goldstar Heavy Industrial Co. Ltd. ("Goldstar") for a possible business expansion of Lotus cars in the People's Republic of China. The collaboration seeks to accelerate the development of Lotus cars in the premium sports segment in China, leveraging on the incentives offered by the Fujian Provincial Government. Both PROTON and Lotus Group are subsidiaries of DRB-HICOM Berhad. Signing on behalf of PROTON was the Honourable Tun Dr Mahathir Mohamad, Chairman of PROTON and former Prime Minister of Malaysia and witnessed by Dato' Abdul Harith Abdullah, Chief Executive Officer of PROTON. Signing on behalf of Lotus Group International Limited, United Kingdom was Jean-Marc Gales, Chief Executive Officer and witnessed by Mr Rohime Shafie, Director of Lotus Group and Chief Financial Officer of PROTON; and signing on behalf of Goldstar was Mr Zheng Qianghui, Chairman of Goldstar and witnessed by Mr Zhai Wenliang, President of Goldstar.
