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.

Mercedes raises the roof on new CLA Shooting Brake [UPDATE]

UPDATE: As we feared, the CLA Shooting Brake is not currently slated for US availability. The text below has been adjusted accordingly. Of all the variants in Mercedes' smallest line, only one doesn't have a liftgate, and that's the CLA-Class. But don't worry, the German automaker is out to fix that too with the reveal of the new CLA Shooting Brake you see here. Based on the same platform that underpins the CLA four-door coupe, the A-Class hatchback, B-Class minivan and GLA crossover, the new Shooting Brake applies a similar formula we've already seen on the bigger CLS Shooting Brake but in a much smaller form – which is to say, it's a wagon, but a shapely one. The revised roofline means more headroom in the back seat and significantly more cargo capacity than the four-door's trunk. Mercedes will offer the CLA with a variety of engine choices, including a 2.1-liter turbodiesel with either 136 or 177 horsepower, a 1.6-liter four with 122, 156 or 211 horsepower. That last model will even be available with 4Matic all-wheel drive for those not enamored by the idea of a front-drive Benz, but the top of the range, of course, is the CLA45 AMG Shooting Brake that carries the same 2.0-liter turbo four – all 360 horsepower of it – as the four-door CLA45 as well as the A45 and GLA45. Driving once again to all four wheels, Daimler says it'll reach 62 in 4.7 seconds (even quicker than the crossover) and top out at the usual 155 miles per hour. Of course those options only apply to markets where the new Shooting Brake will be offered. And unfortunately, Mercedes-Benz USA confirmed to Autoblog that (like the CLS wagon) the CLA Shooting Brake won't be making the transatlantic voyage to US showrooms (where the E-Class is the only low-slung Benz wagon on offer). That leaves the four-door CLA and the GLA crossover still holding down the pint-sized fort for Mercedes. THE NEW MERCEDES-BENZ CLA SHOOTING BRAKE: SPACE FOR SOMETHING NEW Stuttgart. Breathtakingly sporty proportions and a powerfully dynamic design idiom with sensuously shaped surfaces already made the CLA unmistakable in its four-door Coupe guise. It is now followed by a further design icon, the CLA Shooting Brake, with a unique look all of its own. The lower overall height and the elongated coupe-style roof contour line, the low greenhouse and the sweep of the high beltline are the key design features of its distinctive profile.

Mercedes releases 6x6 G63 AMG specs and pics [w/video]

Mercedes-Benz has finally dropped full details on its insane G63 AMG 6x6. The machine puts 544 horsepower to all six wheels thanks to a twin-turbocharged 5.5-liter V8. A seven-speed gearbox shuttles power to the ground via three sets of portal axles, which helps give this machine a full 15.75 inches of ground clearance. By comparison, the standard G63 AMG sits with just 8.27 inches of ground clearance. The extra lift allows this 6x6 to ford nearly 40 inches of water and run massive 37-inch tires. All told, there are five differential locks on this thing, all controlled by a special "locking logic" that provides the best traction possible for any given situation.
The controls offer up three stages of locking, which we can only assume range from JKLOL to OMGWTF. Right now, AMG says this monstrosity is only a show vehicle, but we imagine it wouldn't take much to convince the team to whip up one of your very own. Check out our full gallery and the press release below for all the nitty gritty. While you're down there, you can also check out the video on the machine one more time.
