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 could build production versions of Renault Alpine, Infiniti Emerg-E

As with one of those blockbuster three-team NBA trades that actually improves the fortunes of every team involved, a report in Autocar indicates that Renault, Infiniti and Lotus are in talks that could benefit both manufacturers and enthusiasts. Renault is considering a production version of the devil-in-blue Alpine A110-50 concept but has said that it "probably needs more than the Renault-Nissan Alliance on its own." Enter Lotus, whose Evora platform could supply the running bits for the mid-engined Alpine revival.
That same Evora platform, in range-extended 414E concept form, is the basis for the Infiniti Emerg-E concept. Even though a decision hasn't been made on the Emerg-E's production, it is still being developed and the company has admitted that it "could be built in Britain." For its part, Lotus has said that it's ahead of schedule on the Evora 414E, with its 408 horsepower, 738 pound-feet of torque and 30-mile electric range. Development funds from both Renault and Infiniti could help make all three cars a closer possibility.

What has Lotus got in store for us in Geneva?

In its latest announcement, Lotus has reported a substantial increase in sales over the past nine months of this fiscal year to date. That's good news for the once troubled niche automaker, but the interesting part was hidden further down the release. After detailing the jump in sales by 54 percent worldwide, Lotus announced that it "is revealing an exciting new car at the important Geneva International Motor Show in early March 2015." While little in the way of details were confirmed, the company said that "the product will remain true to its core pillars of lightness, performance and driving purity by embodying all of them in a most desirable package." Sounds pretty Lotus-like to us, but just what form it will take remains to be seen. Given that the Malaysian-owned British automaker has scrapped all of its ambitious new projects, the overwhelming likelihood is that whatever it is preparing to reveal in Geneva will be based on one of its existing models: the Elise, Exige or Evora. The last we heard, Hethel was planning a revision to the Evora, convertible and even crossover versions of the same, as well as an even more hard-core version of the Exige to take the place of the extreme 2-Eleven track car. The announcement refers to the Elise S Cup that was the company's most recent reveal, but seems to indicate that the Geneva show car will be something different. 19 January 2015 Lotus sales up 54% world-wide for the first nine months of the financial year · 81% sales increase EU overall · 88% increase in UK · 143% increase in France · 139% increase in Germany · 29% up USA; 50% up Canada · 24% up Asia and Middle East · 130% sales increases in China; 125% in Japan · Lotus Motorsport shows 19% increase · 163 dealers, 25 more than nine months ago, 50 more in pipeline by the end of 2015. · Exciting reveal in Geneva Announcing that overall sales are up by 54% in the past nine months provides tangible proof that the forward strategy established by Lotus Cars is working. In volume terms, the increase of 551 cars over the previous year, to a total of 1,565, is an excellent result for the British sports car maker. Lotus has enlarged and strengthened its representation globally, with 25 new dealers enrolled across a number of territories in the past nine months, with another 50 new dealers joining Lotus by the end of 2015.
