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 Eletre specs, pricing and more detailed for European launch

Lotus revealed the Eletre in full last year, and while details were plentiful back then, the British sports car company has a lot more for us today in the realm of specs and pricing. Unfortunately, we don’t have a full layout of U.S. specs and pricing yet, but we can get a good idea of what to expect by looking at the European-market model. Three different versions will hit the market at launch: Eletre, Eletre S and Eletre R. Performance is the same between the Eletre and Eletre S (the S simply adds more luxury equipment), but the R is a unique, high-performance variant. For starters, the base model and S will have an electric motor on the front and rear axles good for a combined 603 horsepower and 524 pound-feet of torque. Lotus says that will be enough for a 4.5-second 0-62 mph time and a 160-mph top speed. Driving range on the WLTP cycle is estimated to be 373 miles for these versions, but expect that number to be down when EPA estimates come out.  The Eletre R notches performance up by a wide margin. Its pair of electric motors produce a combined 905 horsepower and 726 pound-feet of torque, but thereÂ’s a little more than just more powerful motors going on here. Unlike the single-speed transmission the base models use, the Eletre R uses a two-speed transmission for the rear electric motor and a single-speed transmission on the front axle. Lotus says this allows them to optimize the car for ideal launch performance and to improve range at higher speeds. The shifts themselves are automatic. Lotus says the R is capable of doing the 0-62 mph sprint in just 2.95 seconds, and it has a slightly higher top speed of 165 mph. Despite the two-speed transmission, range still takes a sizable hit down to just 304 miles on the optimistic WLTP cycle. We also learn today that the Eletre will house a 112 kWh lithium-ion battery pack in all versions of the SUV. Lotus says it features a maximum charge speed of 350 kW on a capable DC fast charger, which is quick enough to bring you from 10-80% in just 20 minutes. AC charging maxes out at 22 kW, which would allow you to go from 0-100% on your home charger in just six hours. The last big spec Lotus shared today is curb weight. If you opt for the base model with no options, the Eletre can weigh as little as 5,489 pounds. And yeah, thatÂ’s obviously a wild amount of weight for anything with a Lotus badge on it, but the Eletre R is even heavier at 5,820 pounds.

Lotus Type 135 electric sports car mixes the Emira with some Esprit

Over the next four years, English sports car maker will make its oft-attempted transformations real by unveiling three "lifestyle vehicles" on its new Premium Architecture. The first is the Type 132 electric crossover, expected to debut in the next few months. After that will come the Type 133 four-door coupe, then the Type 134 crossover that's smaller than the Type 132. In that fourth year, we'll get the Type 135, an electric sports car that will recall the Lotus of old. This electric coupe, sitting on the firm's E-Sports architecture, is being called "a spiritual successor of the Elise," which would be a good thing. The teaser sketch Lotus released to hype up the car also makes us think Esprit, which, as far as we're concerned, is an even better thing. True, there's Elise and Exige and Emira in those exaggerated fenders, but the pointy ends are vintage early Esprit. But the looks aren't the point right now. The reason for the hubbub is Lotus signing a Memorandum of Understanding with British battery firm Britishvolt "to collaborate on research and development of advanced EV technology." The cooperation would put Lotus in charge of "electric propulsion technologies" like motors and control systems, while Britishvolt oversees a "new battery cell package." Goals for the pack are energy density, fast charging and weight reduction. Novel placement is on the menu, too, the E-Sports architecture laid out so that it can also accept batteries in the traditional style under the floor, or behind the cockpit a la a mid-engined sports car. The MOU could give the battery company two clients in one, as the Type 135 will be shared with Alpine across the Channel as well. By the time the Type 135 shows, Britishvolt's $5.1 billion battery factory in Northumberland should have been up and running for two years, ready to supply cells to the Type 135 that will be built at Lotus' historic Hethel, England headquarters (the other Types will be built in Wuhan, China at a manufacturing facility being developed by Lotus parent company Geely). The sports car will come in single- and dual-motor versions powering RWD and AWD trims, those motors expected produce anywhere between 469 and 872 horsepower providing a range of up to 450 miles on the WLTP cycle. The electronics will run on 800-volt architectures, the batteries ranging from 66.4-kWh to 99.6-kWh capacities.  Related Video: This content is hosted by a third party.
