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.

Lotus is building 60 extra light, extra aerodynamic Exige Cup 380s

Lotus is never done adding lightness and once again turned its attention to the Exige. Like so many other special Lotuses, this one, called the Exige Cup 380, makes the same 375 horsepower from its supercharged 3.5-liter V6. However, the weight savings is a significant 117 pounds compared with the 2,447-pound Exige Sport 380. This savings comes from the inclusion of many carbon-fiber parts including a one-piece rear hatch, side intakes, hood, front splitter, side sills, and seats, among others. Lotus also removed the gas struts for the hatch to save 2.2 pounds. And if that's not enough, you can save another 2.2 pounds by choosing the optional HVAC and air vent surrounds, and 22 pounds with an optional exhaust system. The Exige Cup 380 also produces significantly more downforce than the Sport, 43-percent more to be exact. That results in maximum downforce of about 441 pounds at the Cup 380's top speed of 175 mph. The car achieves this thanks to a revised front bumper and splitter, vents above the front wheels, more vents behind the rear wheels, and a new rear wing. Even the windshield wiper rests in a vertical position to aid aerodynamics. The Cup 380 doesn't just benefit from better aerodynamics and less weight. The rear tires are wider than the Sport 380 at 285 mm. The Cup 380 also has two-way adjustable shocks and adjustable front and rear anti-roll bars. Even the stability control can be adjusted to the driver's needs. The car is stopped by four-piston brake calipers at all four corners, and a standard steel roll bar protects the driver. If owners wish, they can also add an FIA-certified full roll cage. Lotus will only build 60 of these Exiges, and they're only available in Europe. They're not cheap either. In the UK, buyers will spend GBP83,000 in the UK and ˆ109,900 in Europe. That means this Exige would cost between $106,000 and $118,000, at current exchange rates. Related Video:
