Lotus CEO Jean-Marc Gales abruptly quits

Jean-Marc Gales is out as CEO at sports car maker Lotus after nearly four years and a track record of turning the company from years of financial losses to a small profit. He'll be replaced by Feng Qingfeng, vice president and chief technical officer of China's Geely Auto Group, who joined the company's board after Geely acquired a majority ownership stake a year ago. Gales will continue as chief strategic advisor to Lotus Chairman Daniel Donghui Li. "Jean-Marc has stabilized and turned Lotus to profitability for the first time in the iconic brand's history, with new industry-leading products and unique business models since joining the company in 2014," Daniel, who is also Lotus' chief financial officer, said in a statement. "Lotus is poised for the next phase of growth under Feng Qingfeng's leadership, where its expertise in lightweight materials and sports car engineering will form part of the wider expansion of Geely's automotive portfolio." Gales told Autocar he was leaving for "personal reasons" and said it was "time to move on." He will head up JD Classics, a British dealer and restorer of classic cars. Gales praised his successor, saying Feng could "unlock the synergies" between Geely stablemates Lotus, Volvo, Polestar and Chinese brand Lynk & Co. Lotus under Gales had been working on updating its aging portfolio of cars — the Elise, the Exige and the Evora — with plans to first update the Elise by 2020. Earlier this year came word that Gales had green-lighted two new sports cars, to be announced later this year and produced in 2020, and an SUV about the size of the Porsche Macan and possibly based on Volvo's SPA platform, which underpins the XC60 and XC90. Lotus under Gales saw sales increase 10 percent in 2017 to about 1,600 sports cars. Related Video:

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 Type 135 electric sports car mixes the Emira with some Esprit

Over the next four years, English sports car maker will make its oft-attempted transformations real by unveiling three "lifestyle vehicles" on its new Premium Architecture. The first is the Type 132 electric crossover, expected to debut in the next few months. After that will come the Type 133 four-door coupe, then the Type 134 crossover that's smaller than the Type 132. In that fourth year, we'll get the Type 135, an electric sports car that will recall the Lotus of old. This electric coupe, sitting on the firm's E-Sports architecture, is being called "a spiritual successor of the Elise," which would be a good thing. The teaser sketch Lotus released to hype up the car also makes us think Esprit, which, as far as we're concerned, is an even better thing. True, there's Elise and Exige and Emira in those exaggerated fenders, but the pointy ends are vintage early Esprit. But the looks aren't the point right now. The reason for the hubbub is Lotus signing a Memorandum of Understanding with British battery firm Britishvolt "to collaborate on research and development of advanced EV technology." The cooperation would put Lotus in charge of "electric propulsion technologies" like motors and control systems, while Britishvolt oversees a "new battery cell package." Goals for the pack are energy density, fast charging and weight reduction. Novel placement is on the menu, too, the E-Sports architecture laid out so that it can also accept batteries in the traditional style under the floor, or behind the cockpit a la a mid-engined sports car. The MOU could give the battery company two clients in one, as the Type 135 will be shared with Alpine across the Channel as well. By the time the Type 135 shows, Britishvolt's $5.1 billion battery factory in Northumberland should have been up and running for two years, ready to supply cells to the Type 135 that will be built at Lotus' historic Hethel, England headquarters (the other Types will be built in Wuhan, China at a manufacturing facility being developed by Lotus parent company Geely). The sports car will come in single- and dual-motor versions powering RWD and AWD trims, those motors expected produce anywhere between 469 and 872 horsepower providing a range of up to 450 miles on the WLTP cycle. The electronics will run on 800-volt architectures, the batteries ranging from 66.4-kWh to 99.6-kWh capacities.  Related Video: This content is hosted by a third party.
