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:

Lotus pumps Exige up to 430 horsepower

It seems that every few months or so Lotus has yet another lighter, faster version of one of its cars, usually with an emphasis on the lighter part. This time, the latest, fastest Lotus gets a big bump in power. It's the Lotus Exige Cup 430, and it shares its supercharged V6 with the recently launched Evora GT430. That means it makes 430 horsepower, an impressive 55 more than the 375-horsepower Exige Cup 380. It also produces 325 pound-feet of torque. That engine is impressive enough in the Evora GT430, but it becomes pretty breathtaking in the Exige, which weighs about 2,410 pounds. Though that's slightly heavier than the Cup 380, the overall power-to-weight ratio has improved, and Lotus says the 430 can fly to 60 mph in just 3.2 seconds from a standstill. It also boasts a higher top speed than the 380, at 180 mph, which is 5 mph more than the 380. Perhaps more impressive is the fact the Exige Cup 430 is the fastest road car Lotus has tested at its Hethel race track, beating the track-oriented 3-Eleven road car by 1.2 seconds. Among the other interesting features of the Exige Cup 430 are the three-way adjustable shocks as well as adjustable front and rear anti-roll bars. More of the car's total downforce, 45 percent to be precise, acts on the front now, compared with 36 percent on the Cup 380. Four-piston brake calipers are used at each corner. It also comes with a number of weight-saving features as standard, including the lithium-ion battery and titanium exhaust. It can also be optioned to be a legitimate race car with an FIA-legal roll bar and airbag delete. But just the stock car isn't cheap. It has three different price tags depending on whether you purchase it in the U.K., Germany, or France. But the cheapest price in dollars comes from the U.K. where it retails for GBP99,800, or just shy of $131,000 at current exchange rates.

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.
