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 and Proton might be sold to Peugeot-Citroen after Geely bails

Despite some strong initial interest, Chinese automaker Geely changed its mind about purchasing a controlling stake in Proton, parent company of Lotus Cars. This leaves Groupe PSA, owner of Peugeot, Citroen, and now Opel, as the sole remaining interested party. This is mixed news for Proton, as Geely's hands-off, cash-flush approach may have helped Lotus. On the other hand, it isn't like Groupe PSA is bordering on bankruptcy. According to Malaysian automotive news site Paultan.org, the reasons behind Geely's change of heart are unclear. In fact, it may seem that the indecision about the deal may have been coming more from Proton, not Geely. Reports say that Proton's parent company, Malaysian manufacturer DRB-Hicom, was uneasy about the potential partnership. DRB-Hicom assembles cars for a number of automakers, including Honda, Isuzu, and Suzuki. A deal with Groupe PSA would give the French automaker access to both DRB-Hicom's facilities and an expanded foothold in Southeast Asia. As only one contender remains, look for news of the deal going one way or another in the next few months. Related Video: News Source: Paultan Lotus Citroen Peugeot Geely groupe psa

Lotus recalls 2008-2011 Elise, Exige and 2011 Evora over fire fear

Lotus is recalling 860 vehicles after discovering that the oil cooler hose could detach from its fitting. Should the hose separate, it could spray oil on one of the lightweight car's tires, giving new meaning to the phrase "sudden loss of grip." The other case is, believe or not, more dire, as the spraying oil could hit the engine and ignite. Of course, neither situation is desirable, hence the recall.
The vast majority of the affected vehicles (780 of the 860) are the 2008 to 2011 Elise and Exige, built between November 2007 and July 2011. Another 80 Evora S coupes from 2011, manufactured between September 2010 and September 2011, are also included in the recall.
All repairs will, naturally, be completed free of charge. In the Elise/Exige's case, that means replacing the hose fittings, while the affected Evoras will get a new hose assembly.
