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 admits its fancy London shop is a waste of money

Piccadilly in London is one of the most expensive shopping streets in the world. And right by where they filmed that awesome scene from American Werewolf in London, Lotus has a showroom. I wandered in last week. Handmade suit, posh watch, smart shoes. But the lack of interest from the sales staff made me think I was wearing a Kimi "Leave me alone I know what I'm doing" T-shirt. To the cognoscenti it's a bit confused. There is no separation between the Lotus F1 team and Lotus cars. Even though a friend at Lotus F1 once told me that the team has a closer relationship with Microsoft than it does with Lotus Cars. What makes this especially strange is that the F1 stuff is front and centre: overpriced caps, T-shirts, and team gear, with the cars playing second fiddle. Yet this is a store paid for by Cars. You have to wonder what the shop is going to sell next year when the Enstone F1 team drops the Lotus name to become Renault. But that is nothing to the wondering you start to do when you speak to the staff. On a previous visit I'd asked about the relationship between Lotus F1 and Lotus Cars, and the sales staff insisted that they were one and the same. A short time after that I spoke to Lotus CEO Jean-Marc Gales at an event where he'd been the guest speaker. He told me that moves were underway to fix the problem and that they would soon have staff in the shop that knew about the cars. So last week's return visit was depressing. In the back there is an Exige and an Elise. I asked the difference and the girl suggested that we look it up on the internet. She took a business card, I made my excuses and left. Daft really I might not have bought a car but I was seriously tempted by the GBP20 carbon fibre pen. My local dealer, Hexagon, called and mailed, but what was really telling, and bloody impressive, was the call from Hethel. I vented my disappointment with the Piccadilly store, and the Lotus man explained. And impressed. Normally you'd get some dreadful company line about how the shop wasn't for people like me, that it was all deliberate to avoid scaring people off and welcome new blood to the brand. But instead he was honest. He told me that the shop was a folly. That it was one of Dany Bahar's many expensive ideas. He signed a ten-year lease on the shop at a million pounds a year and they can't afford to run it. They did train up some good people but, as you can't pay people rural Norfolk salaries and expect them to work in Piccadilly, they left.

A restored Lotus Esprit adds lightness on Petrolicious

Spencer Canon believes the Lotus Esprit is a misunderstood sports car. The wedge-shaped exotics' reputation suggests they are incredibly temperamental, which means lots of expensive repairs. Canon sought to make sure his Lotus didn't suffer from such maladies, which was achieved thanks to a rebuild from a bare shell. The result of his hard work exudes 1980s style with some modern flair and even inspires Canon's career creating bicycles. The Lotus was a wreck when Canon bought it, and he spent months just stripping off the old paint. The car's condition prevented a complete restoration to original spec, so Canon decided to improve the coupe. He modified it in simple ways, such as replacing the power windows with simple pull straps. He also took inspiration from the color scheme on his company's bikes and painted the Lotus blue with a lighter stripe diagonally along the side. The completed sports car angers some purists for not being entirely authentic, but it's hard to argue with the results. Plus, Canon's happy, and nothing else really matters. Canon's Lotus has a rousing exhaust burble once he gets out of the city and out onto the open road. Take a ride with him in the latest video from Petrolicious to hear it yourself and to get a better understanding about the Esprit. Related Video:
