Lotus Exige Sport 410 Quick Spin Review | An unobtainable gem previews an American future

HETHEL, England — You can get the measure of a car brand by the environment in which its products are built. The narrow, bumpy, hedge-lined lanes of eastern England explain a lot about the way a Lotus goes. The character of a company's chief speaks to the brand's intentions as well. Jean-Marc Gales has been portrayed unflatteringly as a Eurocrat bean counter, but his approach has been to strip weight and cost out of the product to the benefit of performance on both track and bottom line, defining brand attributes that Chinese money can hopefully bring to a wider audience. He drives fast, thinks quickly and acts without hesitation. You sense he likes people who do the same, and the speed with which Autoblog posted the story announcing the new Exige Sport 410 is something he commented upon in flattering terms. Despite the fact that it'll never appear on American dealer lots, Gales made us very welcome at the factory to drive it. A quick update on where the Exige is at since it was last seen on American shores in 2011. Though it's still based around what's fundamentally the same extruded and bonded aluminum tub as every other Elise and Exige of the past 20 years, it's gained pounds, cylinders and performance to the point where it shows circuit pace that'll have 911 GT3 owners watching their mirrors. Since going from a 1.8-liter four-cylinder to the Evora-derived 3.5-liter supercharged V6, the Exige has evolved into a proper hot-rod, some way removed from its dainty roots and punching harder with each iteration. And there have been a few. Currently you can buy a Sport 350 or Cup 430 with the uprated, intercooled Evora engine and 430 horsepower, this new Sport 410 related to the latter and benefiting from many of its upgrades but tuned to be more road compliant. And a little cheaper. Unlike the Cup, you can also have it as a roadster, which, in an extreme example of the famed "add lightness" policy, basically equates to removing the roof panel. It's now arguably too much for the local roads, punching hard in angry bursts of acceleration between corners rather than dancing through them. With no power assistance to the steering and fat, grippy Michelin Pilot Sport Cup 2s, an Exige is a surprisingly physical car to drive, bearing in mind it weighs less than 2,500 pounds. A test track built on runways that once hosted U.S. Air Force B-24 Liberators is a better place to appreciate the Exige's talents.

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 Evija to go for Nurburgring EV record

No matter how many times Nurburgring records are made or broken, they still stand as an important automotive measuring stick – at least in a marketing sense. Granted, there are different Nurburgring lengths even on the Nordschleife, and then it all comes down to whether the vehicle is a production car, or completely experimental, or electric, or. Â… Anyway, numbers are numbers, and some numbers are smaller than others, and the Nurburgring is a legendary place to go fast. One of the future plans for Lotus is to bring its upcoming Evija electric hypercar to the ‘Schleife and see if it can go faster than the NIO EP9. PistonHeadsÂ’ article on the Evija featured some interesting tidbits from Louis Kerr, principal platform engineer at Lotus. Kerr said the Evija should be “comfortably quicker” than the NIO EP9 at the Nordschleife, meaning they are gunning for a production EV lap time of way under 6:45. The EvijaÂ’s 70kWh battery pack has reportedly been optimized to provide 2MW peak flow for a sustained seven-minute period, which is practically tailored for a record Ring lap. After that, the batteries would heat up too much to provide peak power. The swappable battery pack can also take “ultra-fast” charging of up to 80kW thanks to active cooling of its li-ion cells manufactured by Samsung. The relatively handy swap-ability of the battery pack is done for the sake of future-proofing, as it means the 70kWh capacity can be upgraded by owners when technology progresses further. Kerr also said that the Evija should be able to hit 62mph from zero in less than the 3 seconds advertised so far, and the targeted 3-second figure should be treated as a “worst case scenario”. The Evija could thus also be able to reach 300 km/h (186 mph) even faster than 9 seconds, as stated. Lotus CEO Phil Popham also said Lotus would be able to build up to 130 units of the Evija, and that several contracts have already been signed with future buyers.
