Lewis Hamilton retakes F1 lead with 'miracle' victory in Germany

HOCKENHEIM, Germany – Lewis Hamilton raced from 14th to first to seize a "miracle" German Grand Prix victory in a Mercedes one-two on Sunday and retake the Formula One championship lead from Ferrari's Sebastian Vettel, who crashed. Vettel, now 17 points behind the Briton after starting eight ahead, led his home race from pole position until rain caused chaos in the closing laps, with the German sliding off and into the barriers. Hamilton, the reigning world champion, took the chequered flag for a record-equalling fourth German Grand Prix win, ahead of his Finnish team mate Valtteri Bottas and Ferrari's Kimi Raikkonen. "I've never had a race like this," said the four-times champion, who was summoned to stewards after the race for a pitlane infringement but escaped with a reprimand and the victory intact. "Today I feel like I drove the best that I can remember driving. I didn't make any mistakes." It was the 66th win of his F1 career, and Mercedes' 80th, and minutes after the finish, the skies opened with an array of thunder and lightning and a torrential downpour that would have stopped any race. "Miracles do happen, mate," Hamilton's race engineer Pete Bonnington told him over the radio after a slow-burner that turned into one of the great comebacks of the Briton's already stellar career. Hamilton, who threw himself across the pitlane wall into the arms of his mechanics and also got a bear-hug from delighted Mercedes-Benz boss Dieter Zetsche, seemed about as stunned as anyone. "I really feel that the rain has come down and just washed away any negativity and its a glorious day," Hamilton said, his voice wobbling. "It couldn't have been a better day for me and one that I will always remember." FERRARI NIGHTMARE Beaten by Vettel in his home British Grand Prix at Silverstone two weeks ago, where he went from pole to the back of the field and up to second, he had turned the tables completely. "Love conquers all," declared Hamilton, who had reacted defiantly on Instagram to the booing and hostility from a partisan crowd after his car broke down in Saturday's qualifying. "It's obviously very, very difficult from that position and highly unlikely but you've always got to believe," added the four-times champion, who said a long prayer before the race started. "I really manifested my dream today." For Vettel, it was simply a nightmare – the chance to make big gains slipping through his hands in an instant. He now has 171 points to Hamilton's 188.

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.
