Max Verstappen wins rain-soaked German Grand Prix

HOCKENHEIM, Germany — Max Verstappen won a chaotic and rain-soaked German Grand Prix on Sunday as championship leader Lewis Hamilton finished 11th and his Mercedes teammate Valtteri Bottas crashed near the end. Verstappen kept his composure on a treacherous track to clinch his second victory this season and seventh of his Red Bull career, topping a surprise podium ahead of Ferrari's Sebastian Vettel — who started from last — and Toro Rosso driver Daniil Kvyat. "It was amazing to win, it was really tricky out there, you had to be focused," Verstappen said. "It was about trying to not make too many mistakes. You learn over the years. I'm very happy with the result." Following this week's crushing heatwave, wet weather caused Hockenheimring havoc as drivers took up to six pit stops for new tires and several crashed at the same spot where a section of tarmac was notoriously slippery. Ferrari driver Charles Leclerc was in contention for a podium, despite starting from 10th, but crashed after switching for quicker tires and slid off the track, over the gravel and into the barriers. Remarkably, Hamilton had the same mishap moments later, mangling his front wing after losing control at the same corner. He came in for a new wing and tires, but it took Mercedes by surprise and a painfully long stop cost him any chance of victory. For Vettel it was a remarkable turnaround, and almost the opposite to last year — when he crashed near the end after leading the race from pole position and Hamilton won, having qualified only 14th. "It was a lot of fun, it was very tough to read what the smartest move was in the conditions," Vettel said. "I stayed tidy in the whole race. Congratulations to Max, he was superb." The red-clothed Ferrari mechanics and engineers mobbed the four-time F1 champion, doubtless relieved after the team's botched qualifying on Saturday. Vettel could not even get out on track to set a time and Leclerc's qualifying bid was undone late in the session, forcing him to start 10th. For Kvyat it was a third career podium but, above all, a point proved. The 25-year-old Russian driver was ruthlessly replaced at Red Bull by Verstappen after just four races of the 2016 season, and could not even get a seat in F1 last year. "Amazing to be back on the podium," Kvyat said. "The race was crazy. Incredible roller-coaster, like my whole career." The track was drenched by the time the race started. For safety reasons, a safety car was deployed.

Mercedes F1 to use Qualcomm 5 GHz WiFi for its tire data

In Formula 1 you need more of everything. More speed, more grip, more hospitality, more money. And you need data, reams and reams of data. The Mercedes-AMG Formula 1 team – the guys with the silver cars driven by 2015 F1 champion Lewis Hamilton and his teammate Nico Rosberg – need so much information that they've teamed with Qualcomm to wirelessly upload thermal imaging data of its tires. During a typical race weekend Mercedes's two racecars will generate approximately half a terabyte of data. Live telemetry has been a feature of Formula 1 for 20 years, though there are more restrictions on it than in the past. (In the days leading up to last weekend's United States Grand Prix in Texas, Formula 1 major domo Bernie Ecclestone said that F1 needs to cease being an engineering war and return more responsibility to the drivers.) Nevertheless, F1 teams gather vast amounts of data during a race weekend, particularly in practice sessions during which restrictions on what they can upload from cars – from engine/power unit parameters to aerodynamic loads – are less prohibitive. For example, during a typical race weekend Mercedes's two racecars will generate approximately half a terabyte of data. Mercedes F1 technical director Paddy Lowe points out that the standard telemetry system simply doesn't have the bandwidth to handle the thermal tire imaging data that the onboard thermal cameras generate. Why do you want a thermal video of the tires? Because it tells the engineers and drivers precisely how much temperature there is across the surface of a tire during a lap, in corners and on the straights. It also indicates how quickly the tires come up to temperature and when they potentially overheat. Understanding the temperature variations allows the team to set the cars up optimally for grip and tire life during a stint. Qualcomm's system works with the race cars like this: Each car has forward- and rear-facing cameras in a winglet mounted on the left side of the engine intake behind the driver's head, which continuously record thermal images of the tires. As a Mercedes enters the pit lane, it passes a Qualcomm 802.11ac WiFi receiver to which it uploads the thermal data. As the car nears the garage, another receiver takes over the upload. Several Qualcomm Snapdragon 805 processors crunch the raw data as it uploads. The data is encrypted – there are always prying eyes in Formula 1.

Rosberg survives the Mexican mess | 2016 Mexican Grand Prix recap

Roughly ten messy laps defined the Mexican Grand Prix – five laps at the start and five at the end. Those laps included a couple of actual wrecks and a few more near wrecks that turned the entire day into chaos. To have any chance of winning the 2016 Driver's Championship, Lewis Hamilton needed to get his Mercedes-AMG Petronas across the finish line ahead of teammate Nico Rosberg. Once again we got a weekend full of vintage Hamilton, the Brit dominating the from Friday to Sunday, except for the first corner of the first lap. Pole-sitter Hamilton reached Turn 1 clearly in front of the field. But he couldn't make the corner and stay on track, so he zipped into the runoff area and over the grass, rejoining at Turn 3 still ahead of the field. The stewards didn't penalize Hamilton, one commentator's explanation being that Hamilton "was not battling another car." The non-action left car #44 to enjoy a lights-to-flag win. At that very same corner, Rosberg also availed himself of the runoff area. His infraction seemed destined to incur a penalty until replays showed that Max Verstappen in the Red Bull slid wide and bumped Rosberg, causing the German to go off track. No penalties were handed out there, either. Verstappen would return to hound Rosberg later in the race when angling for second place. Verstappen took a stab through Turn 4 on Lap 50 of the 71-lap race, but ran off the track and lost touch with the Mercedes by Lap 55. Ferrari got half of its strategy right in Mexico, putting Sebastian Vettel hard on the charge in the final stint. The German got within DRS range of Verstappen on Lap 67, with Red Bull's Daniel Ricciardo a little more than a second behind Vettel. On Lap 68, Verstappen pulled the same move as Hamilton at the beginning of the race: the Dutchman ran wide through Turn 1, zoomed over the grass and rejoined the track at Turn 3, staying ahead of Vettel the whole time. With three laps remaining, the stewards chose to investigate after the race. In spite of Verstappen's own team telling he probably needed to cede position to Vettel, Verstappen stayed in front and slowed just enough to put Vettel under threat from Ricciardo. On Lap 70 Ricciardo had closed up to Vettel's gearbox. Headed for Turn 4, Vettel swung outside to take the corner. When Ricciardo moved inside to pass, Vettel moved inside to block the Aussie while both cars were in the braking zone. The Ferrari made light contact with the Red Bull, but Vettel held his position through Turn 5.
