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: 2014 Spanish Grand Prix is boom and bust [spoilers]

The Spanish Grand Prix's 2.892-mile Circuit de Catalunya is considered a preview for the rest of the season, since it's a combination of long front straight and twisting middle sectors mimic sections from every other Formula One track to follow. After the long break following the flyaway races to open the season, teams and fans have also been looking forward to this race to see if anyone had a realistic hope of catching Mercedes AMG Petronas; Infiniti Red Bull Racing honcho Christian Horner boiled his team's outlook for the season down to the line, "We've got to [beat them in Spain] if we're going to make a championship of it."
If we take that as our starting point then the weekend began as a bust. Lewis Hamilton only just beat Mercedes teammate Nico Rosberg for pole, the Brit's final effort getting him 0.178 seconds clear of the German. Daniel Ricciardo, proving Red Bull is at least the best of the rest, took third but did so more than a second behind Hamilton. Valtteri Bottas of Williams lined up fourth, almost 1.5 second behind and Romain Grosjean delivered overdue good news for Lotus by taking fifth on the grid, more than 1.7 seconds behind pole. Kimi Räikkönen in sixth outqualified his Ferrari teammate Fernando Alonso in seventh, but he couldn't be happy about it because the Ferraris were nearly two seconds behind, and Jenson Button in eighth in the McLaren was more than two second behind. Felipe Massa put the second Williams in ninth, and Sebastian Vettel overcame a terrible start to the weekend to make it into Q3, then didn't set a time when his gearbox failed, then got dropped five places to 15th on the grid when the gearbox had to be changed.
When the lights went out, then came the boom...

Lotus Evora comes in for a facelift

Lotus may have scrapped the ambitious product plans of its previous administration, but don't think it's going to try to skate by on an altogether unchanged lineup. It's preparing what promises to be some major updates for the Evora, which is a good thing because that's currently the only model Lotus offers in the States. And here's out first look at what's in store. It's hard to tell much with all the camouflage disguising it from prying eyes like ours, but you can see this Evora prototype is wearing a new front bumper and what appear to be reshaped side sills that could be redesigned to allow easier ingress and egress – not something for which low-slung Lotuses have been particularly well known in the past. A retuned version of the Toyota-sourced V6 engine is also said to be under the hood, and unburdened a bit by a cut in curb weight. The revised Evora is expected to make its debut next month at the Geneva Motor Show, paving the way for a potential convertible and even a crossover version down the road.
