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 hiring 100 after securing lb100m investment

Lotus is getting a shot in the arm courtesy of corporate parent DRB-Hicom, which has announced a 100-million pound ($152.3M USD at today's rates) investment in the Hethel, UK-based manufacturer. The troubled brand was also in the news last week, with DRB announcing a new, three-year plan that would see variants of existing models introduced.
The money will create 100 new jobs in Hethel, with 45 new engineers, 40 manufacturing operatives and 18 university grads joining the team. Lotus has already seen an uptick in sales this year, according to a Norfolk-based news site, with 40 to 45 cars being produced per week and 722 road cars and 45 race cars sold between January and May. Even sales in the UK have seen a big jump - Lotus only moved 70 units in 2012, but it's already sold 80 cars in the first half of 2013.
Better yet, Lotus is citing an increased demand for its cars around the globe as the motive behind the new hires. While still quite uncertain, Lotus looks like it might finally be on the right track.

See the Lotus Evija in detail in this 23-minute video

Henry Catchpole splits his time as a contributor to Evo magazine with on-camera work for Carfection. The ever-gracious Englishmen took to the studio again recently to pore over the brand new Lotus Evija — and his first gift to us is the electric coupe's proper pronunciation: ee-VYE-yah. For a full 23 minutes, Catchpole tours the coming Lotus hypercar with Lotus' head designer Russell Carr. The two men sweep over the car from front to rear, Carr explaining the origins and details of the many shiny bits that attract Catchpole's eye. The spec sheet alone is attention-getting. A 70-kWh battery fuels a powertrain rated at 2,000 horsepower and 1,254 pound-feet of torque. All-wheel drive and torque vectoring are made possible by electric motors motors front and rear, but the setup is novel. A single drive unit on each axle combines a motor and inverter, but we're told each wheel gets its own gearbox. The package is a little shorter and wider than a Porsche 911, but sits seven inches lower than the roof of the German. Scales bend to the weight of 3,700 pounds in spite of magnesium center-lock wheels, that grandeur managed in part by six Multimatic spool-valve dampers, three on each axle. Just 130 Evijas will be produced, starting next year, each one starting at around $2.1 million. Lotus has filled the coupe with visual flourishes. The Lotus badge on the front is metal inlaid into the carbon fiber bodywork. Carr said he wasn't sure the engineers would be able to finalize that for production, but the designers are hoping. Fans inside the headlights keep the lumens cool, while movable DRLs and turn signals angled like the winglets on an airliner make the lumens look cool. Another neat lighting trick: The "T" in the word "Lotus" on the rear fascia acts as the reversing light. Two features we haven't yet seen on the latest batch of hypercars are adjustable seats, and a strip of metal in the headrests that can be etched the slogan of a customer's choice. And in spite of all the firsts for Lotus in this car, there's one holdover from the Hethel carmaker's other compact sports cars: A dearth of luggage space. The only cubbies are polygonal-shaped holes in the rear of the door sills. It doesn't sound so bad when Catchpole explains it, though, so check out the video.
