Vettel hopes to pull off some Ferrari 'tricks' to end Mercedes F1 dominance

MONTREAL — Sebastian Vettel says Ferrari has a few tricks up its sleeves for this weekend's Canadian Grand Prix and will need to conjure up something special if it is to end Mercedes' magical run. Six races into the season, Vettel is not ready to wave the white flag and concede the title to Mercedes, which has racked up six straight wins, five of them with 1-2 finishes. But the German admits the battle had reached a critical juncture. "The next races will be really crucial for us to try and get back to the front and give a much harder time to Mercedes," said Vettel, who finished second in Monaco last month for Ferrari's best result so far this season. "It will be crucial to do it rather sooner than later, but at the moment I am not too fussed, I am not looking at, 'OK this is the date.' "Clearly we are behind, clearly there is a big margin between Mercedes and the rest and we have to lose that gap and get ahead otherwise it will be difficult to turn around. "That is as much realism as you can get."Vettel won from pole position in Canada last year and Mercedes has suggested the high-speed circuit could again favor Italian rivals whose season has yet to get into gear. But Mercedes drivers Lewis Hamilton and Valtteri Bottas will like their chances as well on the Circuit Gilles Villeneuve. Hamilton was fastest in Friday's early practice, but damaged his car when he hit the wall in the afternoon. The five-time world champion sits 17 points clear of Bottas at the top of the standings and in his bid to equal Michael Schumacher's seven Canadian Grand Prix victories between 1994 and 2004. Not that Mercedes needed another boost, but Hamilton and Bottas will have new and upgraded engines in their cars for this weekend's race. Ferrari has already introduced its first upgraded powerplants of the season, but Vettel was optimistic tweaks to the car would benefit them on a circuit that plays to some of their strengths. "There is always little tricks you can do, the question is whether they make a difference," Vettel said. "But I am not sitting here trying to paint things black we haven't done a single lap this weekend so I am quite optimistic it was a strong track for us last year. "We have some tricks up our sleeves whether they work or not we will see.

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.

Rain prolongs the Championship battle | 2016 Brazilian Grand Prix recap

Rain and an old-school circuit are the antidotes to Formula 1's constricting technical regulations and Tilke tracks. At Brazil's Autodromo Jose Carlos Pace – otherwise known as Interlagos – rain Saturday night and on race day washed away everyone's careful plans, except for those of the man at the front of the pack. Lewis Hamilton put his Mercedes-AMG Petronas ahead of the field throughout the weekend. On Sunday, a storm-delayed start behind the Safety Car assured Hamilton of a clean path to the lead and a clear track. The Briton didn't waste it, pulling out a gap on teammate Nico Rosberg behind, and Rosberg appeared to have no interest in going hard after Hamilton. Safety Cars and red flags kept resetting the gap to zero, though. After the Mercedes-AMG GT S led the first seven laps, it emerged again on Lap 13 for another six laps when Marcus Ericsson crashed his Sauber. Seconds after racing resumed, Kimi Raikkonen aquaplaned his Ferrari into the wall on the front straight. That caused the first red flag, leading to another eight-lap Safety Car interval, then a second red flag stoppage due to conditions on Lap 28, then three more Safety Car laps, and then, finally, racing again. Hamilton never surrendered his lead. The Briton changed tires once during a stoppage, and drove fast enough to cover the full race distance despite the intermissions. Afterward, he said "it was a very easy race." Rosberg had it harder, defending against the preternatural Max Verstappen in third. Barring misfortune it's already clear the Red Bull pilot has at least one Driver's Championship in his career future. In Brazil the young Dutchman drove like he's worthy of the hardware right now. After Verstappen passed Rosberg for second on Lap 34, the Red Bull driver pitted for intermediate tires on Lap 44 – a huge gamble in the conditions – coming back out in fifth. That tire wager failed, giving Rosberg a safe position in second when Verstappen had to pit for extreme wets on Lap 54 of 71. The teenager re-emerged in 16th. Over the race's final 17 laps Verstappen passed 13 drivers at six different places on track. He ran it close-but-clean a couple of times, especially when getting around Sebastian Vettel and Sergio Perez, but he was simply untouchable. Not only did the Dutchman score an amazing third place, he put in what could be the drive of the season.
