Lotus Type 133 / Envya spy photos show it in thin camouflage

Lotus's upcoming electric sedan, codenamed Type 133 and potentially named Envya, has been caught in spy photos once again, and this time we get an impressively clear look thanks to thin, branded camouflage. It looks as long and slinky as ever, and design elements from the Lotus Eletre electric SUV are obvious. It also looks as though it's closely related to the Polestar 5 sedan. The nose of the Type 133 is a near note-for-note remake of the Eletre's, but significantly lower and flatter. Frankly, it's a much better execution of the design to these eyes. It has the split headlights and the hexagonal active grille shutters like the SUV, too. Close examination also shows that the upper headlights consist of two scowling lenses on each side, with the upper ones obscured by vinyl camoflage. The low nose rises quickly over a short hood into the long, raked roofline that continues right through to the tail. The Type 133 is absolutely a modern fastback-type sedan, and likely features a hatchback. At the leading edge of the roof, there's a sensor that's presumably for advanced driver aids, and is one of the signs that this car likely is closely related to the Polestar 5, which was previewed with a similar sensor. Around at the back, the Type 133's details are harder to see due to the final taillights not being installed. But it does appear to be getting full-width units, and there are some diffuser-like details in the rear bumper. Besides that aforementioned sensor, the whole car's shape, size and proportions look extremely close to the Polestar 5's and those of the Precept concept that previewed the Polestar. The low nose, long roof, roof sensor, flush door handles, they're all very similar. And with Geely owning both brands, it's not really a surprise. The same electric platform from the Eletre is likely powering the Type 133, and power could range from 595 to 893 horsepower. Battery packs could range from 92- to 120-kWh. With how finished and thinly disguised this prototype is, we think the Type 133 could be revealed sometime this year, possibly going on sale next year.  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.

2020 Lotus Elise Classic Heritage Editions celebrate past race car liveries

For 2020, the Lotus Elise is getting a very limited edition. The Elise Classic Heritage Edition is a version that can be had in one of four liveries that reference past Lotus race cars. While the paint schemes are fitting tributes, the redundancy of having "Classic" and "Heritage" in the same name seem antithetical to Colin Chapman's philosophy of "simplify and add lightness." Name aside, the color schemes look good. Naturally, one of them is the famous black and gold of the John Player Special Lotus race cars. Others are less familiar, but still significant. Two of them highlight cars driven by famous racers. The blue, red and silver combo references the 1980 Lotus Type 81 driven by Mario Andretti, Nigel Mansell and Elio de Angelis. The red, white and gold version is for the 1968 Type 49B driven by Graham Hill. As for the blue and white car, it celebrates the first Lotus F1 car to win pole position and the race, the 1960 Type 18. The flashy paint is matched with equally flashy interiors. The upper door panels and other trim pieces are painted in coordinated colors, and the seat centers are finished in matching fabric. The one exception is the blue and white model that gets red seats. While the car is based on the 217-horsepower Elise 220, it gets features that are normally extra-cost on that car, including air conditioning, cruise control, a radio, carpeting and floor mats, two-piece brake rotors and forged wheels. Available as options are a hardtop, lithium-ion battery and titanium exhaust. All of these extra features, plus the colors and exclusivity help make the extra GBP6,350-pound upcharge worthwhile, which makes the car cost GBP46,250, or just over $57,000 at current exchange rates. Speaking of exclusivity, only 100 of these cars will be sold internationally. Lotus notes that the split between the different colors will be dependent on demand, so certain liveries could be rarer than others. Don't expect any of them to be offered in the U.S., though, since the Elise isn't available here at all. Related Video:
