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-Maybach GLS could become the most expensive car made in America

Mercedes-Benz International, the German automaker's manufacturing facility near Vance and Tuscaloosa, Ala., already builds the GLS SUV. Autonews reports that the coming ultra-luxe version of the large crossover, the Mercedes-Maybach GLS, will be built in Alabama as well for global markets. The most recent timelines mark the reveal in production or near-production form in China, with sales to commence next year. The next-gen series-production GLS goes on sale later this year. The gilded sub-brand previewed a wild concept last year in China called the Vision Mercedes-Maybach Ultimate Luxury, which blended the tall profile of an SUV with the truck of a sedan on donk wheels. Based on spy shots, none of that fancy will make it to production. Both the Maybach and AMG versions of the GLS ride on fat rubber but look thoroughly traditional. The treasure will be inside. Autonews said China accounts for roughly 75 percent of Maybach S-Class sedan sales. That suggests the GLS in baroque trim will emphasize chauffeured luxury touches like rear captain's chairs and lots of rear legroom. Pricing estimates figure $200,000 to get in the door. That would put the SUV right in line with the Lamborghini Urus and a couple stacks of Benjamins above the Bentley Bentayga, with much the same likely audience. One analyst said, "The ultra-high-net-worth kids want something different, and these ultraluxury SUVs certainly fit that," while another opined on its "appeal to the Kardashians and hip-hoppers, if they want something slightly different to the G-Wagen." A $200K MSRP would also comfortably make the Maybach GLS the most expensive new car built in America, taking the title from the Acura NSX. With a great price comes great power, said to be a twin-turbo V8 with more than 560 horsepower. The coming GLS 450 will make do with somewhere around 360 hp. The Alabama plant, which also builds the GLE, GLE Coupe, and C-Class, is also undergoing a $1 billion upgrade to more than double the size of the facility, making lines for battery production and EQ-series vehicle assembly,

Ecclestone wonders if F1's upcoming turbo V6s should get augmented sound [w/videos]

While every team on the Formula One grid is worried about making a good showing in this year's championship at the same time as they develop a brand-new car for next year's championship, Bernie Ecclestone and F1 circuit promoters have a different concern: how next year's cars will sound. The current cars use 2.4-liter, naturally-aspirated V8s that can reach 18,000 revolutions per minute and employ dual exhaust, next year's engine formula calls for 1.4-liter turbocharged V6s that are capped at 15,000 rpm and are constrained to a single exhaust outlet. Ecclestone and promoters like Ron Walker believe the new engines sound like lawnmowers and that the less thrilling audio will keep people from coming to races. If Walker's Australian Grand Prix really is shelling out almost $57 million to hold the race, every ticket counts. As a fix, according to a report in Autoweek, Ecclestone "suggests that the only way to guarantee [a good sound] may be to artificially adjust the tone of the V6s."
However, neither the manufacturers nor the governing body of F1, the FIA, think there will be a problem. Ecclestone fears that if the manufacturers "don't get it right" they'll simply leave the sport, but the only three carmakers and engine builders left next year, Renault (its 2014 "power unit" is pictured), Mercedes-Benz and Ferrari are so embedded that it would stretch belief to think they'd leave the table over an audio hiccup - if said hiccup even occurs. And frankly, these issues always precede changes to engine formulas, as they did when the formula switched from V10 to V8; fans, though, are probably less focused on the engines and more on the mandated standardization of the sport and the spec-series overtones that have come with it.
No one knows yet what next year's engines will sound like, but we've assembled a few videos below to help us all start guessing. The first is an engine check on an Eighties-era John Player Special Renault with a 1.5-liter V6 turbo, after that is Ayrton Senna qualifying in 1986 in the Lotus 98T that also had a 1.5-liter V6 turbo, then you'll find a short with a manufactured range of potential V6 engine notes, and then the sound of turbocharged V6 Indycars testing last year at the Indianapolis Motor Speedway. Any, or none of them, could be Formula One's future.
