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.

China's Geely says it has no plan to buy Fiat Chrysler — as FCA stock leaps

HONG KONG — Chinese carmaker Geely Automobile denied media speculation on Wednesday that it planned to make a takeover bid for Fiat Chryslerk Automobiles (FCA), the world's seventh-largest automaker. Geely was one of several Chinese carmakers cited in by Automotive News, which said representatives of "a well-known Chinese automaker" had made an offer this month for FCA, which has a market value of almost $20 billion. "We don't have such a plan at the moment," Geely executive director Gui Shengyue told reporters at an earnings briefing, when asked if Geely was interested in Fiat. He said a foreign acquisition would be complicated, but he did not elaborate. "But for other (Chinese) brands, it could be a fast track for their development," Gui added. However, a source close to the matter said FCA and Geely Automobile's parent firm, Zhejiang Geely Holding Group, had held initial talks late last year, without disclosing their nature. The source confirmed Geely was no longer interested in FCA, noting that the parent company had only three months ago announced its first push into Southeast Asia with the purchase of 49.9 percent of struggling Malaysian carmaker Proton, a deal that also included a stake in Lotus. Geel's denial failed to dent FCA's stock. The price of its Milan-based shares has jumped more than 10 percent to a 19-year high since Automotive News first reported on Monday, citing unnamed sources, that FCA had rejected the Chinese offer as too low. FCA stock on the New York Stock Exchange rose sharply on Monday from $11.60 to $12.38 and on Wednesday was trading at $12.84. FCA declined to comment on Wednesday. FCA Chief Executive Sergio Marchionne has repeatedly called for mergers as a way of sharing the costs of making cleaner, more advanced cars, but he has repeatedly failed to find a partner and retreated from his search for in April, saying FCA would stick to its business plan. He has also spoken of spinning the successful Jeep and Ram divisions off from FCA. Europe's largest carmaker, Volkswagen, and General Motors have both said they are not interested in talks with FCA. On Wednesday, Geely Automobile reported a doubling of first-half profit, above expectations, as cars designed with Sweden's Volvo won over domestic consumers. Volvo is a unit of the Zhejiang Geely group, and has recently announced it will share its technology with Geely.

Lotus opens the 2013 Formula One season with the launch of the E21 [w/video]

Lotus has broken the seal on the 2013 Formula One season, launching the E21 car at its factory in Enstone. With the regulations this year quite similar to those of last year, there are no dramatic changes in form compared to the E20. After some teams lobbied to be able to cover the stepped nose with a "vanity panel," Lotus retained the configuration, the team's technical director saying that the panel would add more weight and didn't make sense to put on the car unless it also added performance.
Beyond that, the E21 is said to be an comprehensive advance in its details - the suspension gets a new layout, the Coanda exhaust and the passive double DRS system are evolutions from last year, the front wing is "a continuation of concepts" from 2009.
After securing fourth in the Constructor's Championship last year, this is the chassis that drivers Kimi Räikkönen and Romain Grosjean will use to try and move the team up a place, which would mean beating one of the big three teams over the course of the season. The quietly and impressively consistent Räikkönen managed third in the Driver's Championship, and we're sure he wouldn't mind a move up in the standings, either.
