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.

France formally moves to ban Mercedes vehicles using contested refrigerant

That didn't take long. Shortly after a French administrative court gave the French government a ten-day window to reconsider its ban on registrations of Mercedes-Benz A-, B- and CLA-Class cars using the prohibited R134a refrigerant, the government cited an EU directive to formalize banning the sale of the cars. The country's environmental ministry said that registrations "will remain forbidden in France as long as the company does not to conform to European regulations," meaning so long as they do not use the approved R1234yf refrigerant.
Daimler had won the administrative court decision by challenging France's application of a "safeguard" provision in which the EU allows a country to block sales of cars that would "seriously harm the environment." In spite of Daimler's victory, France has cited that very provision as basis for the continuation of the ban.
Daimler got permission from Germany's KBA federal motor authority to keep selling cars with the coolant banned by EU politicians, and is using that national permission as the right to sell the cars throughout Europe. Meanwhile, above that battle, German politicians are asking the EU to let Mercedes sell the cars in France while the KBA does more testing, at the same time as the EU is threatening Germany with repercussions if it doesn't bring the KBA and Daimler into line.

2016 Mercedes-Benz GLC one-ups old GLK in every way

Meet the Mercedes-Benz GLC-Class, the latest in the automaker's increasingly impressive run of new or significantly updated (and occasionally renamed) vehicles that's included the immensely good C- and S-Class, and the upcoming GLE-Class – formerly known as the M-Class crossover. Unlike the GLE, which you'll be reading our First Drive on shortly, the GLC is much more than a mid-cycle refresh, representing the second-generation of Mercedes' compact crossover. While it represents a more significant update to the former GLK than the GLE does to the ML, the new GLC shares its looks with the larger vehicle. It's a handsome take on Mercedes' latest design language, featuring a similar rectangular, two-slat grille in the fascia. The greenhouse has hints of C- and S-Class in it, and is the best way of viewing the 4.6-inch stretch to the wheelbase. The taillights, meanwhile, take their inspiration from the S-Class Coupe and AMG GT. The new cabin isn't just prettier, it's more spacious, too. The C-Class and S-Class also serve as inspiration for what is a remarkably attractive cabin. While Audi has long served as the standard for interior design, with the C, S, and now the GLC, Mercedes can stake a claim to Ingolstadt's crown. Like the C-Class, the center stack is a wide, curving design that terminates in the controller for the infotainment system, while a tablet-like display sits up high. Leather, wood, and aluminum cover most every surface we can see in the initial batch of photos, while cool, blue accent lighting adds an extra dose of style. The new cabin isn't just prettier, it's more spacious, too. Thanks to the longer wheelbase, there's an extra 2.2 inches of space for second-row passengers. There's more room for cargo, too. Mercedes claims 20.5 cubic feet – non-SAE, it should be noted – behind the second row, up from 16.5 in the current GLK. While the GLC will be offered with a range of gas and diesel powertrains, US consumers will be offered the GLC300 first. Counterintuitively and like the C300, the entry level CUV uses a 2.0-liter, turbocharged four-cylinder engine with 241 horsepower and 273 pound-feet of torque. While we expect 4Matic to be the popular option, Mercedes will also offer a rear-drive-only model. There's no mention of additional powertrains beyond the launch model, although we'd expect the GLC to follow the C-Class' example and add a GLC400 powered by a 3.0-liter, twin-turbocharged V6.
