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: 2013 Bahrain Grand Prix follows the template of this year and last [spoilers]

The sand, the wind, the penalties, the contact and the one crash - all of them collided to make the Bahrain Formula One Grand Prix a surprise affair from day to day and lap to lap. Oh, and did we mention the tires? Pirelli made a last-minute swap after the amusement park ride that the Chinese Grand Prix turned into with the soft compound tire, and brought medium and hard compounds to the desert. That didn't stop things from falling apart for some teams - literally - and that didn't stop the one team that seems to love the hard compound Pirelli tire.

Lotus F1 confirms Grosjean, Maldonado for 2015

With the season-ending Abu Dhabi Grand Prix now just ten days away, the focus is beginning to shift to next year's Formula One World Championship, with more and more pieces to the puzzle falling into place. And the latest news comes from the Lotus team. The Enstone-based outfit has confirmed that it's keeping both its drivers right where they are for next season, with Romain Grosjean partnering Pastor Maldonado once again.
Swiss driver Grosjean, now 28 years old, made his grand prix debut with the team in 2009, returned as test driver in 2011 while winning the GP2 title, returned to the F1 grid in 2012 and has been driving for the team ever since. He's scored nine podium finishes to date, but has finished no better than his eighth place this season.
Venezuelan pilot Maldonado, 29, won the GP2 the year before his teammate, and moved up to F1 with Williams, for whom he drove for three seasons before switching to Lotus for this one. He shocked the field when he won the Spanish Grand Prix in 2012, but has only finished in the points once this season.
