Lotus Evora, Exige, and Elise add lightness to Geneva

The folks at Lotus have been quite busy over the past few months adding lightness to their vehicles. Since December, the company has introduced lighter, quicker versions of the Evora, Exige, and Elise, and all three members of the trio are present at the 2016 Geneva Motor Show. Each one is special in its own way, but if you crave a nimble sports car, you probably wouldn't be disappointed with any of these new models. The Evora Sport 410 is the most luxurious member of the bunch, at least by Lotus standards. At 2,921 pounds, it's also the heaviest, but a 410-horsepower 3.5-liter supercharged V6 makes this one the most powerful, too. The coupe can rocket to 60 miles per hour in 3.9 seconds and to a 186-mph top speed. Lotus will make just 150 of these special Evoras per year, and they'll have carbon fiber parts for the roof, tailgate, sports seats, and more. Best of all, this will be the only one of these three that will get a North American version. The Exige Sport 350 Roadster is the coolest member of this group, featuring tartan seats that we absolutely love. It's also the quickest of the three, reaching 60 mph in just 3.7 seconds, and it tops out at 170 mph. The rapid sprint is possible because the 345-hp 3.5-liter supercharged V6 only needs to push 2,480 pounds. The Elise Cup 250 rounds out the group with the lightest weight at 2,053 pounds (2,030 pounds with the optional Carbon Aero Package) but the least power at 243 hp. However, it certainly isn't slow with a 60-mph run in 3.9 seconds and a top speed of 154 mph. Lotus plans to make just 200 of them year each year. If you could pick any one of the three, which would you choose? The Evora might be the most livable every day but chucking around the Elise could be a barrel of fun. There're also those fantastic seats in the Exige. Let us know in Comments which one you want the most.

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.

Xcar tosses the Lotus Evora 400 around in the rain

Lotus appears to be blooming again after a rocky period, and the company is launching the Evora 400 here in December for $89,900. Xcar just got a hold of one of these updated coupes on a rainy day to find out if it can be a Porsche competitor. With 400 horsepower, the aptly named Evora 400 tops the Porsche Cayman GT4 by 15 ponies, and with a purported sprint to 60 miles per hour in 4.1 seconds, the Lotus also nudges out the Porsche by a tenth of a second. So on paper, the two coupes are quite comparable. Of course, Xcar also digs deep into more subjective factors, like how it actually feels behind the wheel. If you think you prefer a little more wind in your hair, the company is developing an Evora 400 roadster, too. Rather than an actual droptop, the roof will reportedly consist of two, removable carbon-fiber panels. It'll arrive on these shores in the coming years as part of Lotus' re-emergence.
