Lotus Emeya concludes winter testing, brings unique treats

Think of the Lotus Emeya as the sedan form of the Eletre SUV, transferring Lotus' newest brand values into a body style closer in spirit to the old Lotus. As the automaker marches toward production later this year, we've got a few more details on what's to come with the English foe of the Taycan competitor. Battery size is said to be 102 kWh; if that's accurate, that would be down slightly on the Eletre SUV's gross 112-kWh battery that provides a usable 109-kWh. Lotus says the sedan's range will be "broadly similar" to the Eletre, which is rated to go up to 373 miles on the WLTP cycle. The sedan, like its brother, is built on an 800-volt system capable of 350-kW fast-charging, and uses two motors to power both axles. A top-shelf Emeya R trim should pack the same power as the Eletre R, 905 horsepower and 726 pound-feet, the Emeya's lower profile and lighter weight taking a coupe of tenths off the Eletre's 2.95-second sprint to 60 miles per hour.  At least two wild specs separate the Emeya from the Eletre: A 55-inch augmented-reality head-up display. Lotus says the projection on the Electre is 29 inches. In addition to being "the largest and most advanced in any Lotus," it offers "a Snow Mode which turns the display blue, helping the driver to see the outline of the road more easily against a white background." Who needs an Apple Vision Pro, eh?  The sedan also fits an active rear spoiler that's four inches broader than the SUV's from front to back, at 11.7 inches compared to 7.7 inches. Adjusting the spoiler's angle on the SUV can produce up to 112.5 kilograms of downforce. The sedan's spoiler rings up a maximum of 215 kg of downforce at speed. The Emeya's top speed is an electronically capped 159 mph, six miles per hour below the SUV's, done to preserve battery health.  Lotus recently concluded a series of winter tests that are part of the company's three-year development testing across 15 countries, working out the Emeya in temps as low as negative 13 Fahrenheit and locking the car in a freezer at -40 F to gauge how its systems performed.  After going on sale in China, the Emeya heads to Europe and then to the U.S., so we shouldn't expect it until sometime next year, joined by the Evija hypercar. Car magazine said it saw a Lotus presentation that mentioned an MSRP of $100,000, almost identical to the base Porsche Taycan's U.S. MSRP.  Related Video:

Lamborghini Countach, Ferrari 512M and more immortalized as Lego sets

Lego has announced a slew of new Speed Champions sets, the ones based on actual licensed cars, for 2022. The latest batch includes a smorgasbord of supercars, from beloved classics like the Lamborghini Countach to yet-to-be-released promises like the long-awaited Mercedes-AMG One. There are seven cars in total, released in five sets.  Our favorite is probably the 262-piece Lamborghini Countach, based on a later LP500 variant. Not only does it tick the box of a childhood dream machine, but the angular shape of the real-life Countach lends itself well to being recreated in Lego bricks. Also, it's modeled in white rather than the typical red. Lego Speed Champions Ferrari 512M 1 View 6 Photos We also really dig the Ferrari 512M. It marked the last of Ferrari's V12 endurance racers, and even though it was soundly spanked by the Porsche 917, the cars are undeniably beautiful. The 291-piece Lego set does a great job of capturing its brutal wedge silhouette in brick form. Lego Speed Champions Lotus Evija 1 View 5 Photos Rounding out the single-car sets is the 247-piece Lotus Evija. The electric Lotus has a bit of a generic supercar look about it, but that's not entirely the fault of the Lego kit. Its dramatic vents can't really be replicated with the limited "resolution" of the Lego bricks. Its rear, with unique taillight-encircled air tunnels, is a bit more distinctive. Lego Speed Champions Aston Martin Valkyrie AMR & Vantage GT3 1 View 7 Photos In addition to the single car sets, there are two larger sets of two cars each. One is a 592-piece Aston Martin-themed pack that includes the Valkyrie AMR Pro and Vantage GT3. Again, it's a bit difficult to sculpt the cars' curvaceous lines out of straight-edged bricks, but the effort is admirable. The Valkyrie is probably the more successful of the two, as the Vantage would resemble a Corvette or Viper if it didn't have stickers to clarify the details. Lego Speed Champions Mercedes-AMG F1 W12 E Performance & Project One 01 View 9 Photos Last but not least is a twofer comprised of 564 bricks to build the Mercedes-AMG One and seven-time Formula 1 world champion Lewis Hamilton's W12 racer. In Lego's official product description the driver is not mentioned by name, but the number 44 gives it away. The model of the One indeed looks like a sharp supercar, but the blocky pieces don't exactly replicate the lines we've seen on camouflaged test mules.

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.
