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.

2015 Spanish F1 Grand Prix makes its Deutsche mark

The first race of the European Formula One season inaugurates the second phase of the Championship. Teams overhaul their cars with the big updates they've been working on since Australia, and at the end of The Battle of Spain we find out how the positions on the field have changed. Mercedes-AMG Petronas driver Nico Rosberg brought a big update to his psychology, straight-up beating teammate Lewis Hamilton to take his first pole position of the season. Mercedes owns the front row and Ferrari maintains its status as primary challenger, Sebastian Vettel lining up in third. Williams proved it's been hitting the books to do better in class, though, Valtteri Bottas slotting into fourth. And Toro Rosso's visit to a track that rewards strong aero rewarded them with the best team grid position since the Italian Grand Prix in 2008: Carlos Sainz secured fifth, ahead of Max Verstappen in sixth. Kimi Raikkonen's bout of Saturday woes – it seems the Finn is always handicapped by lots of tiny issues – continued in Barcelona with one of his sets of prime tires getting cooked by malfunctioning tire warmers. He recovered well enough to take seventh on the grid, but he's got some strong competition ahead of him. He led three other drivers in the Continuous Issues department, Daniil Kvyat unable to wrestle his Infiniti Red Bull Racing higher than eighth, Williams driver Felipe Massa getting it wrong in Turn 3 to fall five places behind his teammate Bottas, and Daniel Ricciardo in the second Red Bull enduring another engine change and sloppy car behavior to get tenth. And while it turned out to be a steady race a little rough around the edges, the positions on the battlefield just might have changed. A little. Of the 66 laps in the race we might have seen Rosberg for three of them – maybe. The German got a smashing start, had a clear lead into Turn 1, and after that we checked in occasionally during his two pit stops and again at the checkered flag. He owned the entire weekend the way we're used to seeing his teammate do, and the cameras left him alone to run his race. No one got within seven seconds of him during the first third, and as the pit stop strategies played out that cushion grew. He finished seventeen seconds ahead of Hamilton, and 45 seconds ahead of third-placed Vettel. Hamilton, on the back foot all three days, stumbled out of the gate.

Lotus marks 20 years of the Elise

Lotus was a very different company 20 years ago. For starters, it wasn't owned by the Malaysians: it had just been sold by General Motors to Romano Artioli, the same man behind the revival of Bugatti EB110. It had discontinued the Elan, Excel and Carlton, which left the Esprit – by then already 20 years old itself – as its only product. Then the Elise came along and everything changed. The Elise arrived in 1995, based on a lightweight aluminum chassis that was ahead of its time and cloaked in composite body panels to make it incredibly light in the spirit of Colin Chapman's ethos. Its name was taken from Artioli's granddaughter, but stuck around long after he sold the company. The Esprit was eventually retired, and with the exception of the Evora, the Elise served as the basis for every other new Lotus that has followed in the two decades since: the Exige, Europa, 2-Eleven, 340R, and so on. It even lent its underpinnings to a wide array of sports cars for other automakers, including the groundbreaking Tesla Roadster, the all-conquering Hennessey Venom GT, the Opel Speedster/Vauxhall VX220, and more concepts cars and niche products than we can count. Now 20 years since its introduction, Lotus is celebrating the milestone with the Elise 20th Anniversary Edition. It's based on (and effectively replaces) the Elise S Club Racer, and trims a further 22 pounds off the curb weight. It's got matte black forged wheels and trim, a retrimmed interior and of course all the special badging. UK customers will be able to pick one up for GBP39,900, but as the Elise hasn't been offered Stateside in a few years now, we'll just have to admire – and celebrate – from afar. Lotus Elise celebrates 20 years - Celebratory 20th Anniversary Special Edition Elise - Special edition, based on the Elise S Club Racer, including classic Elise colour schemes - Pioneering and iconic Elise continues to innovate and evolve - Weight reduced by 10 kg The Lotus Elise 20th Anniversary Special Edition celebrates the unveiling of the iconic sports car at the Frankfurt Motor Show in September 1995. 20 years ago, the Lotus Elise revolutionised the sports car world, setting the benchmark for handling, purity of the driving experience, lightweight and efficiency. Its pioneering and advanced bonded aluminium chassis was a market-leading technological innovation at the time and over the years has improved and evolved and remains core to the Elise's exceptional performance today.
