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 renames Russell Carr its head of design

There's been a changing of the guard at Lotus recently. The legendary British sports car manufacturer fired its controversial chief executive Dany Bahar and replaced him recently with Jean-Marc Gales. And now it's named a new chief designer. Or rather, renamed its old one to the post.
That designer is the appropriately named Russell Carr, who had previously held the post until Bahar brought in his former compatriot Donato Coco (with whom he had previously served at Ferrari) and charged him with designing a series of ambitious but ill-fated concept cars that debuted at the 2010 Paris Motor Show and were subsequently axed on Bahar's way out. Now Coco has been shown the door as well, effective at the end of this month. In his place, Carr - who has been with Lotus since 1990 - has been given back his old job after having been demoted to playing second fiddle to Coco for five years.
Although both Gales and Coco both served in senior positions at PSA Peugeot Citroën, Gales didn't join the French automaker until 2009 - the same year that Coco joined Lotus, five years after having left PSA to work at Ferrari.

Born-again Lotus Esprit will be a hybrid in more ways than one

Volvo parent company Geely is helping Lotus end its drought of new products. The storied British company is allegedly developing a mid-engined hybrid coupe it will position as a spiritual successor to the Esprit. The yet-unnamed model will slot above the existing Evora as a more usable and more refined alternative, according to sources who spoke to Autocar. It will ride on a modified Evora platform, but the two cars won't look anything alike; the upcoming hybrid will liberally borrow styling cues from the electric Evija hypercar.  The planned gasoline-electric powertrain will make the coupe a hybrid in more ways than one. The space directly behind the two-seater cabin will be occupied by a V6 sourced from the Toyota parts bin, and the electrified portion of the system will consist mainly of components provided by Volvo. An output over the 500-horsepower mark is likely, but more specific technical specifications remain guarded. What's nearly certain is that the Lotus engineering team will go to significant lengths to offset the weight added by the lithium-ion battery pack. Insiders described the coupe as a stop-gap between the current-generation Lotus models, including the Elise still sold in many global markets, and an array of upcoming sports cars that will ride on a new platform. Another one of the company's future models is an SUV — its first — built on Volvo bones and aimed at the Porsche Macan.  Lotus will introduce its mid-engined coupe during the first half of 2021, still according to Autocar, and sales will begin shortly after. It's too early to tell whether the model will be sold in the United States, but the company has previously indicated it wants to broaden its foothold in our market in order to grow, so we'd bet on seeing it here. This isn't the first time Lotus has tried to reboot the Esprit. In 2010, under the leadership of Dany Bahar, the company took the Paris auto show by storm when it unveiled five close-to-production concept cars including one that previewed a modern-day Esprit. The project was far too ambitious and none of the models shown in the French capital made it to production. In 2012, Lotus vehemently refuted rumors claiming it had canceled the Esprit, which was penciled-in for a 2013 launch, but hindsight is 20/20. Time will tell if two's the charm.
