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.

'The best Lewis' Hamilton faces resurgent Ferrari in F1

SHANGHAI (Reuters) - Lewis Hamilton has raised his game but whether the Mercedes driver can deny Ferrari a second successive win of the season in China this weekend remains to be seen. On paper, the triple world champion is still the man to beat -- the most successful driver by far in Shanghai with four wins to date. "Lewis is the best Lewis that I've seen in the last four years, both on and off the track," said Mercedes team boss Toto Wolff after the Briton started on pole and finished second to Ferrari's Sebastian Vettel in the Australian season-opener. "He has become a pillar of this team and he proved that in Melbourne." But Vettel is leading the championship, the first time a non-Mercedes driver has done that since he took his fourth title with Red Bull in 2013, and once-dominant Mercedes have a fight on their hands. Mercedes, who have taken both the drivers and constructors' titles for the last three years, have won four of the last five races in China. As Melbourne showed, however, past form may count for little in a season of sweeping rule change. "If you think you are going to cruise to victory in the future, based on a track record of success, you'll be proven wrong very quickly," said Wolff. "Australia was a weekend full of lessons, now we go to China ready and excited for another battle." Ferrari have not started a season with consecutive wins since 2004 at the peak of the Michael Schumacher era, the Italian team taking 15 victories from 18 races that season. Vettel's win in Australia ended a victory drought for Ferrari stretching back to September 2015, and drew rare praise from company chairman Sergio Marchionne, but they must now prove they can be genuine contenders. "You really have to go step by step," said Vettel. "It's good to know that we have a great car but it's just the beginning: new regulations, new generations of cars so there will be a lot of progress." The cars this year are longer and wider, sporting fatter tires and more swept-back bodywork as part of a rules shake-up aimed at making them faster, more spectacular to watch and harder to drive. But overtaking has also become more difficult, with Australia raising concern about the lack of real moves. The long straights and wide sweeps of the Shanghai circuit saw 128 passes last year, more than at any other track, and should provide a more definitive verdict.

Mercedes-Benz releases US-spec 2014 Sprinter details

Last week, Mercedes-Benz released the details for the updated 2013 Sprinter intended for global markets, but this week it has announced what changes are being made to the US-spec version of the van for the 2014 model year, including the Freightliner model. As expected, most of the changes made to the European model will be present on the 2014 Mercedes-Benz Sprinter when it goes on sale in the US, which is expected to be this fall.
The biggest difference between the Sprinter announced last week and the one headed to our shores is what is found under the hood. While European Sprinters will come with diesel engines and offer the availability of a supercharged four-cylinder gasoline or CNG engine, US Sprinters will still offer the 3.0-liter V6 BlueTEC diesel. This year's Sprinter now comes standard with a new base engine, the 2.1-liter four-cylinder BlueTEC diesel. This smaller engine will produce 161 horsepower and 265 pound-feet of torque, and will be paired to a seven-speed automatic transmission; the optional 3.0 V6 puts out 188 hp and 325 lb-ft of torque, and will be mated to a six-speed auto.
Fuel economy for the new Sprinter has not been announced, but Mercedes-Benz has made numerous changes with the goal of improving efficiency. To this end you'll find a new, low-friction rear axle and the optimization for the generator, fuel pump and power steering pump.
