Lotus Evija's wild aero setup is detailed by chief aerodynamicist

The Lotus Evija is a car of firsts for Lotus. To that end, the company has spent a lot of time talking over the details. Today, we get to learn about the wild shape’s aerodynamics and what Lotus engineers were trying to accomplish. Richard Hill, chief aerodynamicist for Lotus takes a dive into all the details, and the video at the top of this post offers a great visual. “Most cars have to punch a hole in the air, to get through using brute force, but the Evija is unique because of its porosity,” Hill says. “The car literally ‘breathesÂ’ the air. The front acts like a mouth; it ingests the air, sucks every kilogram of value from it – in this case, the downforce – then exhales it through that dramatic rear end.” We can see what Hill means as we look at the Evija in photos. Instead of a regular front bumper, this one has pass-throughs that direct the air back into the side of the car. Lotus hasnÂ’t released the all-important coefficient of drag figure yet, but we have to imagine itÂ’s very low. The front splitter (below, left) is responsible for a few different things. The opening in the center takes in air to cool the battery pack that is mounted behind the seats. Then, the outer section of the splitter channels the air to the “e-axle” for cooling of the electrical components. And finally, it also produces downforce.  There are a couple more tunnels for air to pass through in the rear. These “holes” are likely the most distinctive design feature, especially when accentuated with the LED taillights. Hill says that these are also fully functional and help to reduce drag. “They feed the wake rearward to help cut drag,” Hill says. “Think of it this way; without them the Evija would be like a parachute but with them itÂ’s a butterfly net, and they make the car unique in the hypercar world.” On top of all these porous body structures, there are pieces that move. The rear wing can elevate upward from its flush body position and deploy into clean air above, creating more downforce. And then thereÂ’s an F1-style drag reduction system. This uses a horizontal plane that deploys from the car to make it slipperier through air. The final big piece of this puzzle is the underbody sculpting that directs air into the massive rear diffuser. This causes an upwash of air, in turn creating a massive amount of downforce. Hill sums it up quite nicely.

Lotus hops into Extreme E with Jenson Button ahead of first race weekend

The Extreme E racing series is filling out with a host of interesting names, and Lotus is the latest manufacturer to join the fray. Lotus is hopping in as technical partner to the Jenson Button Extreme E team, making it quite the British powerhouse. A single photo of the rally vehicle is above with a simple JBXE and Lotus livery. Seeing Lotus hop into electric racing makes sense given that it will be pushing the Evija hypercar out the door soon. The company says it will be leveraging the experience it gained in development of that car to help it succeed on the motorsports side. “We are on the cusp of an exciting new era of electrified motorsport, and weÂ’re delighted to support the JBXE team as Technical Partner,” says Matt Windle, managing director of Lotus Cars. “The complex technicalities of EV racing present a fascinating challenge, and using our learnings from more than a decade of electrifying sports cars – most recently with the Lotus Evija hypercar – we can bring valuable knowledge to the team.” Jenson Button is acting as both the team owner and driver of the car in the Extreme E series. Other notable car companies hopping into the series include GMC (a Hummer partnership), Fisker, Hispano Suiza and Cupra. Other racing outfits are also hopping on without the support of major car manufacturers. The field has just nine teams right now, but the slow trickle continues with promising entries. This latest development with Lotus and Jenson Button is just another feather in the seriesÂ’ cap. "Lotus is a great British brand that is inextricably linked to motorsport, so we are delighted to welcome Lotus Engineering to JBXE,” Button says. “Extreme E is a unique and exciting formula, full of 'world firsts' and challenges, and to announce that a brand such as Lotus Engineering is coming on this journey with us is a proud moment for myself and the team. We are very excited about our new technical partnership and canÂ’t wait to show what we can do in the first race this weekend.” That first race — termed the “Desert X Prix” — will take place in Saudi Arabia this weekend. ItÂ’s airing on Fox Sports in the U.S. The second race is nearly two months after this upcoming one and will take place in Senegal.

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:
