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 Exige S gets automatic transmission option

A vehicle as light and agile as the Lotus Exige is all about driver involvement, but those enticed by the nimble sports car's handling and performance who aren't keen on working a stick shift now have another option at their disposal.
Lotus has just announced the availability of an automatic transmission on both the Exige S and Exige S Roadster. For an extra couple thousand euros or pounds sterling, customers will now be able to order a six-speed automatic transmission. The two-pedal setup includes paddle shifters and Sport or Race modes that optimize shifting for "a more spirited drive."
Equipped with the slushbox, the Exige S Automatic is just as quick around Lotus' famous factory test track in Hethel, and even pips the manual version's 0-62 time by 0.1 second, now down to 3.9. Unfortunately, since the Exige isn't available Stateside anymore, however, American buyers can't get their hands on either version.

Lotus sells loads more cars, earns way more money

Sports-car company Lotus has reason to be excited. It released some facts on its sales and financial performance for the 2016 and 2017 fiscal year, and it has seen some impressive improvements. According to the company, it sold nearly 60 percent more cars in mainland Europe compared with the 2015/2016 fiscal year, and it sold six times as many cars in the U.S. compared with that year. This helped it go from a loss of GBP16.3 million for the previous year in earnings before interest, taxes, depreciation and amortization (EBITDA) to a GBP2 million profit EBITDA. The fact that those numbers are given before all those extra expenses is noteworthy, though, as it means the company isn't truly profitable yet, despite major gains. The company did report numbers that only excluded tax, and those show the company still lost money. But the good news is that it lost much, much less money than the year before. Before taxes for the 2015/2016 fiscal year, the company lost GBP41.2 million, and this year, it only lost GBP11.2 million. The company expects it will be profitable before tax in the coming year. So Lotus isn't perfectly healthy yet, but this, combined with Geely's recent acquisition, shows it's well on its way to becoming fit as a fiddle. We like the cars Lotus makes, so we hope that things keep getting better, and that we'll maybe get more Lotus models in the future, beyond just the Evora road car and 3-Eleven track car.
