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.

Caterham inks US distribution deal with Superformance

Sort of like an automotive big box store, Superformance is rapidly becoming the destination for anyone interested in modern kit cars. Besides the normal spattering of Shelby Cobra replicars, Superformance also offers replicas of the GT40 and Corvette Grand Sport. Now, we can add an altogether different type of DIY car to the company's portfolio - Caterham.
Superformance has just been announced as the new US distributor for Caterham Cars, effectively adding the entire suite of Lotus variants to the company's catalog. While there will be a large variety of models available, according to Caterham the mix will skew toward more powerful offerings. As much as we like the affordable appeal of a Seven 160 or Roadsport, simply having the wildly powerful 620 R or Superlight R500 available in the US is a good thing for enthusiasts.
"In the last two years, Caterham has significantly broadened its reach internationally and signing a new official distributor in the form of Superformance in America is a natural extension of how our brand is expanding, rapidly, across the globe," Caterham Group CEO Graham Macdonald said.

Lotus F1 Team promotes Joylon Palmer for next season

After letting its longtime protege Romain Grosjean go to the Haas F1 team, Lotus has named his successor for next season. Driving for the team as it transitions back to being the Renault factory outfit will be one Jolyon Palmer, the current reigning GP2 champion and possibly one of the best-poised drivers to make it into Formula One. The 24-year-old Brit has been steadily working his way up the formula racing ladder, winning races in Formula Two and GP2 over the past several years before winning the latter title last season. During that victorious campaign he also served as a test driver for Force India, before switching to Lotus this season and getting 10 grand prix practice sessions under his harness. Jolyon's own experience undoubtedly sealed the deal, but his upbringing surely put him in a prime position to make it in single-seater racing. He's the son of former F1 driver Jonathan Palmer, himself a past Formula Two champ before completing half a dozen seasons in Formula One. It's what the elder Palmer's been up to since leaving the grid, however, that's put the son in such a strong position. As head of MotorSport Vision, Jonathan Palmer controls five major racing tracks across the UK – including BrandsHatch, Outlton Park, Snetterton, Cadwell Park and the Bedford Autodrome. He also runs a couple of trackday programs, founded the now-defunct Formula Palmer Audi series and continues to operate the FIA Formula Two Championship, the BRDC Formula 4 Championship, and the British Superbike Championship. All of which gave young Jolyon plenty of room to run as he developed his career. Will that be enough to put the young Palmer in a position to win next season? Only time will tell. But he arrives at a pivotal time for the team, which is expected to transition back from the privately held Lotus operation to Renault's hands, running once again as the factory team – but saddled with an engine package that has been underperforming against the competition. One way or another, it ought to be an interesting time to be in Enstone. Related Video:
