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.

Our love of SUVs is killing people in the streets

Americans are fond of supersized fast-food meals and colossal convenience-store fountain drinks, even though they're clearly bad for our health and U.S. adults keep getting fatter. We also like large vehicles, and our love affair with SUVs is killing people in the streets. According to a recent investigation by the Detroit Free Press/USA Today, the increase in SUV sales over the past several years coincides with a sharp rise in pedestrian deaths in the U.S. — up 46 percent since 2009, with nearly 6,000 people killed in 2016 alone. With SUV sales surpassing sedans in 2014 and pickups and SUVs currently accounting for 60 percent of new vehicle sales, it's no wonder Ford announced in April plans to cease U.S. sales of almost all passenger cars. And this followed Fiat Chrysler's move to virtually an all-truck, -SUV and -crossover lineup. While the Freep/USA Today investigation found that the simultaneous surge in SUV sales and pedestrian deaths comes down to vehicle size, it also points to a lack of action on the part of the National Highway Traffic Safety Administration (NHTSA), even though it knew of the dangers SUVs pose to pedestrians. Also blamed are automakers dragging their feet on implementing active safety features. Using federal accident data, the Insurance Institute for Highway Safety (IIHS) determined that there was an 81 percent increase in single-vehicle pedestrian fatalities involving SUVs between 2009 and 2016. Freep/USA Today's analysis of the same data by counting vehicles that struck and killed pedestrians instead of the number of people killed showed a 69 percent increase in SUV involvement. As far back as 2001, researchers at Rowan University forecasted a rise in pedestrian deaths as Americans began switching to SUVs. "In the United States, passenger vehicles are shifting from a fleet populated primarily by cars to a fleet dominated by light trucks and vans," the researchers wrote, with light trucks comprising SUVs.

2016 Mercedes-Benz Metris First Drive

We're sitting 8,700 feet above sea level in the idyllic old mining town of Dunton Hot Springs, nestled deep in the Rocky Mountains of Colorado. We've come to drive the newest and cheapest Mercedes-Benz, a midsize work van called the Metris. As the day begins, Mercedes van boss Bernhard Glaser states the obvious, "We're setting up camp in the US." It's a good line, perhaps a little too fitting given our surroundings, but it's accurate. Though the US commercial van market is dominated by Ford and General Motors, Mercedes has staked out a competitive position and is digging for more. The tall, capable Sprinter relaunched with a Mercedes badge in the United States in 2010 and has grown into a $1-billion enterprise in America. Now comes Phase 2, dubbed "Mission Metris," starring a tweener van that's smaller than the towering Sprinter yet larger the Ford Transit Connect and Nissan NV200. The 2016 Metris enters a crowded and evolving segment that also includes the Ram ProMaster City and GM's super-old Chevy Express and GMC Savana. Mercedes will sell the Metris in cargo and passenger forms, meaning it will be outfitted for a range of roles, including taxi and limousine companies, delivery duties, service, and maintenance. Yes, your cable guy might show up in a Mercedes. That's part of the plan, actually. Though the Metris was engineered to be a pack-mule of a van, if the shine of the star on its grille helps attract new buyers – like a chain of upscale hotels that needs a fleet of shuttles – all the better. Our short test drive begins outside the small canyon town of Dolores, CO, as we haul four people and some luggage to the airport in a pre-production Metris. Normally test programs staged by automakers are a little contrived – many feature an off-road course or track time for even the most mundane vehicles – but our stint behind the wheel of the Metris is almost exactly how the van could be used in real life. We make our way along Colorado's winding highways, cruising around 60 miles per hour for much of it. The Metris offers an excellent view of the road and the snow-capped mountains that rise in the distance. It's an easy van to drive. We don't feel like we're piloting a U-Haul or something else cumbersome. Mercedes is billing this as the 'right-sized' option, and our initial impressions support that sentiment as we navigate the curves flanked by steep drop-offs.
