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.

Race Recap: 2013 Korean F1 Grand Prix crazy enough for Psy [spoilers]

The end of qualifying for the 2013 Korean Formula One Grand Prix left us with five pairs: two chassis each from Infiniti Red Bull Racing, Mercedes-AMG Petronas, Lotus, Ferrari and Sauber. Yes, Sauber. The last time the Swiss team had two drivers in the top ten was Japan last year, when Kamui Kobayashi converted the grid spot into a podium.
But let's start at the front of the top ten, where Sebastian Vettel put his Red Bull on pole for the 42nd time in his career. He was followed by Lewis Hamilton in second place by two-tenths of a second, Mark Webber in the second Infiniti Red Bull, and Romain Grosjean in the Lotus in fourth. Out-qualifying teammate Kimi Räikkönen again, the Finn would line up in tenth. Nico Rosberg put the second Mercedes in fifth, Fernando Alonso got the first Ferrari into sixth ahead of teammate Felipe Massa, while Nico Hülkenberg led with the first Sauber in eighth, teammate Esteban Gutiérrez showing the promise he was hired for (okay, and his money) in ninth. Except they'd all move up a place because Webber had to serve his ten-place grid penalty after getting his third reprimand of the season in Singapore. That would get Sergio Perez in his McLaren into tenth. Yes, McLaren needed a grid demotion ahead to make it into the top ten.
It was an entertaining top ten that no one would have expected. When the red lights went out, we were treated to one of the most entertaining races of the year - it was Gangnam Style at 300 kilometers per hour.

U.S. issues new tariff threat, this time against British-built cars

WASHINGTON — Britain is the United States' closest ally but their long friendship may be sorely tested as the two countries try to forge a new trade agreement after Britain's exit from the European Union. U.S. Treasury Secretary Steven Mnuchin said on Saturday in London that he was optimistic that a bilateral deal with Britain could be reached as soon as this year. But Mnuchin gave up no ground after a second meeting with his UK counterpart, Sajid Javid. Javid has insisted that Britain will proceed with a unilateral digital services tax, despite a U.S. threat to levy retaliatory tariffs on British-made autos. Mnuchin told reporters after Saturday's meeting that such taxes would discriminate against big U.S. tech companies like Alphabet Inc's Google, Apple, Facebook and Amazon. The UK Treasury declined to comment on the private meeting. The divide highlights the challenges ahead as the Trump administration seeks a new bilateral agreement with Britain, part of a broader push to rebalance relations with nearly all its major trading partners. The stakes are high — British Prime Minister Boris Johnson has pegged the trade deal with United States as a way to ease the pain of breaking with Europe, Britain's largest trade partner. U.S. President Donald Trump, has promised a "massive" trade deal to support Brexit, the product of a populist movement similar to his "America First" agenda. The goodwill and special relationship the two countries have enjoyed for decades may not count for much, experts say. "Trump is not going to be doing Johnson any favors," said Amanda Sloat, a senior fellow with the Brookings Institution in Washington. "He's not going to give him a trade deal without major concessions." Even before the digital tax issue arose, the Trump administration threatened to tax foreign car imports, which could hit British-made Jaguar, Land Rover, Mini, and Honda Civic hatchback cars. Stiff U.S. trade demands include increased access for U.S. farm goods, concessions that will be difficult for Britain's entrenched natural food culture to swallow. The United States also wants Britain to change the way its National Health Service prices drugs and allow in more U.S. pharmaceuticals, which could prove politically unpopular for Johnson's government. Washington's demand that London block Chinese telecoms equipment maker Huawei Technologies Co Ltd for national security reasons could also cloud talks.
