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 announces four EVs and moves its technology division to China

Lotus took a big leap towards the mainstream with the announcement it's building four new EVs, and only one is a sports car. The others include a sedan and two SUVs. And on top of the new product announcements, the automaker revealed its Lotus Technology division is going to set up headquarters in Wuhan, China. With the Elise out of the picture and its pockets full of cash from Geely – parent company to Volvo, too – Lotus is moving forward with its ambitious expansion plans. It announced it will grow its line-up of models with four electric cars shown in the sketch above: an SUV called Type 132 internally and due out in 2022, a sedan marketed as a four-door coupe known as Type 133 and expected to go on sale in 2023, a second SUV referred to as the Type 134 that will make its debut in 2025, and a sports car currently dubbed Type 135 that we'll allegedly see in 2026. This isn't the first time Lotus has made wild claims about its future, but this time it might actually have the funds to pull it off. We knew that an SUV was in the pipeline, leaked patent images may have revealed its exterior design, but the sedan and the second high-riding model are new additions to the company's product roadmap. Lotus explained its so-called "premium lifestyle" vehicles (read: four-door models) will all ride on a new platform called Lotus Premium that's said to be highly modular. Its wheelbase can vary from about 114 to 122 inches, and it can take battery packs with a capacity of 92 to 120 kilowatt hours. It's also compatible with an 800-volt charging system, and Lotus claims vehicles built on the new architecture will be capable of reaching 60 mph from a stop in less than three seconds. As for the other news, while Lotus ostensibly remains based in Hethel, England, its historic home, the Lotus Technology subsidiary broke ground on a new facility in China in August 2021. Lotus explained it formed the division to develop batteries and energy management systems, electric motors, electric control systems and other EV components. Investing in Wuhan rather than in Hethel will certainly raise more than a few eyebrows. It's a move that brings Lotus closer to its parent company and some of its key investors, such as Nio, while pivoting it away from its historic home and its main markets.

Jay Leno goes old school with 1966 Lotus Elan 26R

On the latest episode of Jay Leno's Garage the guest's are both from inside the garage: the man they call Professor Jim Hall, Leno's master fabricator, and the 1966 Lotus 26R that he spent 18 months building. The Elan 26R was the racing version of the Elan that Lotus founder Colin Chapman began building after watching privateer teams prep their roadgoing Elans for competition duty all over Europe. Built by the factory from 1964-1966, drivers like Jim Clark and Jackie Stewart won silverware in the roadster called "the giant killer."
Hall, a veteran Lotus wrench, started with the 1966 Elan street car and turned it into a 26R that's arguably better than the factory original. Except for the engine block and head, original 26R body and Elan chassis, just about everything is custom built, highly modified or special order, from the fabricated oil pan, brake lines, safety wiring and oval exhaust tubing to the six-speed sequential transmission.
The episode is an unusually-long 21 minutes because, as an in-house build, Leno can go through the process of putting the whole roadster together. When he takes it for a drive and keeps going on about how it sings, you can hear it, too. It's worth the time to check out Mr. Hall's Opus in the video below.
