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.

The Caterham Seven Sprint is a perfect retro-style British roadster

A Caterham Seven oozes retro style. Modern engineering may mean the car no longer shares any parts with its original Lotus counterpart, but one look at the little roadster and it's easy to see the car's heritage. Caterham loves pumping out variants of the Seven, and the 2016 Goodwood Revival seemed like the perfect place to announce the latest version, the throwback Caterham Seven Sprint. Caterham calls the Seven Sprint a design "that was seemingly planned in the mid-1960s but never launched." It's apt then that the company is using it to kick off its "60 Years of the Seven" celebrations. The Seven Sprint is based off the European-only 160 model, meaning it's powered by an 80-hp turbocharged three-cylinder Suzuki engine. While the bonkers Seven 620 R may be the biggest and baddest Caterham available, the bare bones Seven 160 just feels more appropriate here. There are a number of retro styling touches throughout the car. The limited edition Seven Sprint comes wrapped in one of six colors originally offered by Lotus in 1966 and 1967. The Chassis is powder-coated grey, just like the Series 2 Lotus Seven. The cream-colored wheels feature polished hubcaps, while the interior features a wood-trimmed wheel and the interior is trimmed in a wonderful shade of red. The body has been slightly reworked to look more like the original Lotus designed car. Mechanically, not much has changed. Power from the Suzuki three is fed through a five-speed manual. Some of the suspension bits are similar to Colin Chapman's original design, but that's true of the standard 160. The car should be just as much of a riot as any other Caterham, just packed to the gills with style. The Seven Sprint is available only as a fully-complete factory car. It's unknown if any of the 60 produced will make it to the US. Prices in the UK start at GBP27,995, or about $37,000.

Watch Evo pick its 2015 Car of the Year in this epic video

With just a few days left in 2015, it's the perfect time to check out Evo's annual Car of the Year test to determine the greatest performance vehicle of the last 12 months. The writers' picks for the 11 finalists spanned a breadth of engaging models and included: Peugeot 208 GTi by Peugeot Sport, Lamborghini Aventador SV, Seat Leon Cupra Sub8, McLaren 675LT, Porsche 991 GT3 RS, Porsche Cayman GT4, Honda Civic Type R, Ferrari 488 GTB, Chevrolet Camaro Z/28, Lotus Evora 400, and Mercedes-AMG GT S. For the venue to test the mettle of these performance machines, Evo stuck close to home this year and visited the twisting roads at the beautiful north coast of Scotland. Racing brothers Marino and Dario Franchitti also came along for the ride to provide two more voices in the competitive challenge to determine a winner. Evo's video explains why each model deserves to be among such rarified company but doesn't gloss over their faults either. There can be only one winner, though. We don't want to spoil it, so check out the clip for magnificent views of these performance machines through the Scottish countryside.
