Race Recap: 2015 US Grand Prix was wet, wild, and historic

Hurricane Patricia made landfall in Mexico this weekend, and made her presence known throughout the South. For two of the three days of the grand prix weekend it rained non-stop in Austin, so badly on Saturday that qualifying had to be postponed until Sunday morning, and then it only stayed dry enough to conduct the first two sessions. At the end of a tricky, slippery Q2 Nico Rosberg had put his Mercedes-AMG Petronas on the front row, one tenth ahead of teammate Lewis Hamilton. The German had done the best he could to keep his hair-thin chances of a World Championship fight alive. Daniel Ricciardo lined his Infiniti Red Bull Racing chassis in third ahead of teammate Daniil Kvyat, both drivers having moved up a place because Ferrari driver Sebastian Vettel took a ten-spot grid penalty for using a fifth engine and dropped to 13th. Continuing the two-up theme, Sergio Perez and Nico Hulkenberg were fifth and sixth for Force India. After that came variety: Felipe Massa in seventh for Williams, Max Verstappen for Toro Rosso in eighth, Fernando Alonso looking good in the rain for McLaren in ninth, and Romain Grosjean for Lotus in tenth. When the lights went out, Turn 1 set the tone. Pole position is on the outside line at Circuit of the Americas, and Hamilton had got himself far enough under Rosberg by the time the two got up the hill that Rosberg had to stick to the outside through the corner. At the corner exit Hamilton used the entire track, pushing Rosberg wide, their cars touching. As Rosberg left the track and dropped back to fourth, Hamilton radioed to the team to say the contact was unintentional. The two Mercedes' and two Red Bulls animated the front. Rosberg passed Ricciardo at the end of a Virtual Safety Car period employed to let the marshals clean the debris at Turn 1. Kvyat started chasing down Hamilton until the Russian ran wide and let Rosberg and Ricciardo through, then Rosberg ran wide on the next lap to let Ricciardo through. On Lap 15, Ricciardo passed Hamilton through the esses to take the lead. After the first round of pit stops the Aussie still had the lead, followed by Rosberg, Kvyat, Hamilton, and Vettel. Then Rosberg got around to take the lead and Vettel closed in on Hamilton as the Brit duked it out with the Russian. Rosberg showed excellent speed, building up a nine-second gap on Ricciardo, but a Safety Car period erased that when Marcus Ericsson had to park his dead Sauber on the inside of the track after Turn 10.

Coca-Cola returning to F1 with Lotus sponsorship [w/videos]

Even before Red Bull Racing became a record-breaking three-time Constructor's Champion in Formula One, it has dominated conversations both as a team and as an energy drink. After seven years of "Red Bull this" and "Red Bull that," Coca-Cola is reportedly ready to jump into the F1 fray with its Sweden-based energy drink Burn.
Rumors had placed Coca-Cola's entry with McLaren F1, but it's actually Lotus that has secured the deal. We have no idea what the sponsorship will look like, but the website for Burn says that "We [intend] to foster that creativity by incorporating art and music in a way that will break the conventions of traditional F1 sponsorship," Lotus F1 team principal Eric Boullier adding "We are excited to partner with burn to build a new and innovative model for sponsorships that will combine experiences, content creation and social media..."
Since most - including this writer - have no idea what Burn is, we've included a couple of Burn commercial spots to help get us up to speed, which you'll find below. The 2012 season hasn't even ended, and we're already looking forward to 2013...

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.
