Lotus Evija X track special appears in spy photos at the Nurburgring

Few people would say the Lotus Evija is lacking in performance. It's meant to make just shy of 2,000 horsepower and is light for an electric car at around 3,700 pounds. But apparently Lotus wants to go further. These spy shots reveal a wild track-only special that's clearly labeled the Lotus Evija X testing at the Nurburgring. We're assuming this X will be substantially lighter than a regular Evija. It has a bare carbon body with seemingly fewer individual pieces. The headlights are gone and so are the rear windows. The interior appears gutted, too. That carbon body is far from stock, too. It's much wider and has all manner of downforce-producing add-ons. The front has a massive front splitter and canards and cutouts above the front wheels. The sides even have wide splitters with struts. And the X's crown aero accessory is that enormous wing that rises well above the roof.  The wide body also encompasses fat slick racing tires that are almost certainly not street legal. They bear the Pirelli P Zero name on the sidewalls, and they're wrapped around center-lock wheels. AP Racing brakes are tucked inside. There are of course plenty of questions surrounding the Evija X. It's definitely a track-only machine, but is it a one-off, or is it going to be sold in extremely limited numbers to select buyers? Maybe Lotus wants to take the Evija racing? Though it seems more like a rules-be-damned type of car like the Pagani Zonda R. Or maybe the Volkswagen ID.R, the fastest electric car to lap the 'Ring, would be a closer analogue to the Evija X. The spy photographer that provided these photos said the track was rented out for the day by Lotus, and some sort of notary was on hand, likely to certify a lap time. If Lotus is gunning for an EV lap record there, the Evija R is going to be outrageously fast. The ID.R's time sits at a shocking 6:05.336. And if the Lotus tops it, it would become the second fastest overall car at the 'Ring. We'll definitely be looking forward to more details and an eventual lap time. Related video:

Race recap: 2015 Singapore Grand Prix full of odd sideshows

What greeted the Formula One teams in Singapore? Confusion. The haze was so thick that observers wondered if the race would be held at all. Then practices began, and Mercedes-AMG Petronas driver Nico Rosberg took the first one, but the team fell away after that. Mercedes said it couldn't get the tires turned on, but no one believed the Silver Arrows was in genuine trouble. Then qualifying set the confusion in stone. Ferrari driver Sebastian Vettel laid down the best time in Q3, taking the team's first pole position since Germany in 2012. Daniel Ricciardo got his Infiniti Red Bull Racing into second, about one tenth behind Vettel. (That may make the team feel better after Ricciardo publicly asked for a better engine than the current Renault unit, and team advisor Helmut Marko said the outfit will quit F1 at the end of this year if it can't get a stronger powerplant for 2016.) Kimi Raikkonen put the second Ferrari in third, Daniil Kvyat put the second Red Bull in fourth. And only then came the Meredes'. Lewis Hamilton's best got him fifth, the Brit saying, "We don't really know what we have got wrong. For some reason the tires are not working on the car. We do the warm-up the same as everyone else and then you see someone one second up the road." For added emphasis on the reversal of fortune, his time was 1.6 seconds behind Vettel's. Teammate Rosberg is next to him in sixth, a further half a second back. Williams is still a hurting a bit on slow tracks, so Valtteri Bottas could only get into seventh ahead of Max Verstappen in the Toro Rosso and teammate Felipe Massa in ninth. When the red lights went out, the 2015 Singapore Grand Prix would get both less interesting and more interesting all the way to the final lap. The men up front got good getaways, and the order into Turn 1 was Vettel, Ricciardo, and Raikkonen. The race finished with those three in that order, never having conceded position. Vettel's Ferrari enjoyed the track so much that he laid a second per lap into Ricciardo for the first five, then relaxed. He'd let the gap come down later in the race a couple of times, but any time he wanted to see what his mirrors looked like without anyone in them he'd take off again. Rosberg took fourth position after holding down sixth for the first stint. It looked like he'd have an even worse day - for a Mercedes driver - when he had problems getting his car started and onto the grid before the race.

This is how ground effects work in a nutshell

There are two ways to generate downforce. One is with all manner of wings and spoilers on the surface of the vehicle. The other is with ground effects. One you can clearly see, the other remains something of a hidden mystery. Fortunately, the good folks at Lotus and Goodwood are here to dumb it down for us non-engineer types. It's called Bernoulli's Principle, named after Swiss physicist Daniel Bernoulli who literally wrote the book on the subject way back in the 1700s. Countless engineers have spent their careers focused on its study and application, but the crux of the matter is that, as the speed of air (or other "fluid") increases, pressure decreases. Play with the air's increasing speed and decreasing pressure just right and you can generate downforce underneath the body of a car without significantly increasing drag as you would with surface spoilers. For evidence of how Bernoulli's Principle applies in practical terms, just look at the last Ferrari to pack a turbocharged V8 in the middle and the latest one. The F40 had a giant wing on the back, where the 488 GTB has none. But because the 488 uses underbody aerodynamics (or "ground effects"), it generates significantly more downforce than the winged F40 ever could, and at lower speeds. Ferrari, however, was not the first outfit to harness the power of ground effects. Lotus did with the legendary 79 that Mario Andretti drove to the world championship back in 1978. That was the genius of Colin Chapman, and to explain how it all works in layman's terms, our friends over at Goodwood Road & Racing brought in Colin's son Clive Chapman, head of Classic Team Lotus, to put together the video above.
