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.

Race Recap: 2014 Spanish Grand Prix is boom and bust [spoilers]

The Spanish Grand Prix's 2.892-mile Circuit de Catalunya is considered a preview for the rest of the season, since it's a combination of long front straight and twisting middle sectors mimic sections from every other Formula One track to follow. After the long break following the flyaway races to open the season, teams and fans have also been looking forward to this race to see if anyone had a realistic hope of catching Mercedes AMG Petronas; Infiniti Red Bull Racing honcho Christian Horner boiled his team's outlook for the season down to the line, "We've got to [beat them in Spain] if we're going to make a championship of it."
If we take that as our starting point then the weekend began as a bust. Lewis Hamilton only just beat Mercedes teammate Nico Rosberg for pole, the Brit's final effort getting him 0.178 seconds clear of the German. Daniel Ricciardo, proving Red Bull is at least the best of the rest, took third but did so more than a second behind Hamilton. Valtteri Bottas of Williams lined up fourth, almost 1.5 second behind and Romain Grosjean delivered overdue good news for Lotus by taking fifth on the grid, more than 1.7 seconds behind pole. Kimi Räikkönen in sixth outqualified his Ferrari teammate Fernando Alonso in seventh, but he couldn't be happy about it because the Ferraris were nearly two seconds behind, and Jenson Button in eighth in the McLaren was more than two second behind. Felipe Massa put the second Williams in ninth, and Sebastian Vettel overcame a terrible start to the weekend to make it into Q3, then didn't set a time when his gearbox failed, then got dropped five places to 15th on the grid when the gearbox had to be changed.
When the lights went out, then came the boom...

1991 Lotus Elan | eBay Find of the Day

Lotus has always been a company that goes its own way, and the 1991 Elan you see above is quite possibly the strangest vehicle that the British automaker has ever designed and built. It's powered by a 1.6-liter turbocharged four-cylinder engine that sends 162 horsepower to the front wheels through a 5-speed manual gearbox. This generation of the Elan, which was produced from 1989-1995, remains to this day the only front-wheel-drive vehicle that Lotus has ever sold. And it wasn't very popular, with only 3,855 sold worldwide and less than 600 imported to the United States. That makes it a very rare car indeed. Lotus promotional materials claimed there were "definite advantages in traction and controllability," and added that "drawbacks such as torque steer, bump steer and steering kickback were not insurmountable." Road tests of the front-drive Elan almost universally praised the vehicle's excellent handling performance. The car you see here, sold by Gateway Classic Cars of Fort Lauderdale, Florida, looks to be in pretty good overall condition. The mileage is on the high side at nearly 111,000, but it has new paint, a new convertible top, and a refurbished interior. The asking price stands at $16,995, which makes it one of the least expensive vehicles to wear a Lotus badge that you can park in your garage and enjoy.
