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:

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.

Lotus bids farewell to the Elise and the Exige with Final Edition models

Lotus will put the Elise, the Exige, and the Evora out to pasture later in 2021 to make room for a new model that internally is being called Type 131. Before it embarks on this major lineup overhaul, the firm will send off the Elise and the Exige — two of its best-known and longest-running models — with a limited Final Edition. Fittingly, the Final Edition models represent the ultimate evolution of the Elise and the Exige, nameplates released 25 and 21 years ago, respectively. Lotus added power and, somewhat surprisingly, equipment without straying from the famous "light is right" philosophy that shaped both cars. Collectors have two variants of the Elise (Sport 240 and Cup 250) and three of the Exige (Sport 390, Sport 420, and Cup 430) to choose from. Stepping inside either Final Edition version of the Elise reveals a thin-film transistor (TFT) instrument cluster that can be configured with regular gauges or a racecar-like display, depending on whether motorists plan to hit the road or the track. Lotus also redesigned the steering wheel to give taller drivers more space. New upholstery and stitching patterns round out the major updates, and every Final Edition wears a specific metal plaque. Outside, the changes include new additions to the palette, including Azure Blue, which was one of the launch colors when the Elise was presented to the press in 1996. Racing Green, the hue worn by the model when it made its global debut at the 1995 edition of the Frankfurt auto show, makes a comeback as well. If 2,032 pounds is too heavy, Lotus offers optional parts (like carbon fiber panels) that shed 53 pounds. Power for the Elise still comes from a supercharged, 1.8-liter four-cylinder engine mounted directly behind the passenger compartment. It delivers 240 horsepower (23 more than stock) and 180 pound-feet of torque, figures that give the roadster a 4.1-second zero-to-60-mph time. Selecting the Cup model brings a full body kit that generates 145 pounds of downforce at 100 mph and 341 pounds at the Elise's 154-mph top speed. Like the Elise, the Exige range receives Final Edition-specific paint colors, decals, and other exterior accents. Inside, it's a similar story: Lotus added a TFT screen and a new steering wheel, among other updated parts. Instead of a four-cylinder, the Exige packs a meaner punch thanks to a supercharged, 3.5-liter V6 tuned to put 397 horsepower (a 47-horse increase) and 310 pound-feet of torque under the driver's right foot.
