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-Benz A45 AMG shows up to fight the hottest hatches [w/videos]

Fun coincidence. On the same day that Audi announces the unveiling of its new S3 Sportback at the Geneva Motor Show, Mercedes-Benz steals the spotlight by confirming that the all-new A45 AMG will also receive its official debut early next month. Starting life as the entry-level A-Class hatchback, the A45 AMG gets the full AMG treatment, which includes numerous performance, handling and styling upgrades.
Under the hood sits an AMG-tuned 2.0-liter turbocharged I4 breathing through a sport exhaust system helping the five-door produce 360 horsepower and 332 pound-feet of torque. This engine is paired to a seven-speed AMG dual-clutch transmission and power is sent to the ground using 4Matic all-wheel drive. Mercedes-Benz says that the A45 AMG will be able to accelerate from 0-60 miles per hour in under 4.5 seconds and it will have a top speed of 155 mph; in the land of hot hatches, it doesn't get much hotter than that. For added performance and handling, AMG has retuned the A-Class' suspension and steering systems and equipped The A45 with a three-stage stability control system that is specific to this car.
Surprisingly, the exterior styling of the A-Class was already sporty enough that the new model doesn't receive too many changes to become the A45 AMG. The biggest alterations include black accents to the chin spoiler, rocker panels and mirror caps, black wheels with red-painted brake calipers and rectangular dual exhaust outlets. Inside, it doesn't take a trained eye to spot the differences. The flat-bottomed sport steering wheel and the numerous red accents throughout the cabin (including the seatbelts!) really help to make this AMG interior stand out; front passengers will also get sport bucket seats that appear to be more than supportive enough for even the most spirited driving conditions.

'55 Mercedes Gullwing racer expected to sell for $6 million

RM Sotheby's has a Gullwing up for auction. Not just any Gullwing, but one of just four prepared by the factory for racing. And it's expected to fetch $6,000,000, (give or take a million) when it crosses the auction block next month in New York. Chassis number 5500640 is billed as "the rarest and most desirable W198 Gullwing ever presented for public auction," and it's not hard to see why. It was used for both racing and testing purposes, including an entry in the notoriously grueling Tour de France by none other than Sir Stirling Moss. He placed it second only to the Marquis de Portago in his Ferrari 250 GT TdF, often outperforming the Ferrari in stages of the event. It was in the possession of one owner since 1966, who stored it for 40 years before passing it on to his son in 2008, who in turn underwrote a comprehensive three-year restoration project and has now put it up for auction. Gullwings are invariably the most sought-after post-war production Mercedes when they come up for auction. The highest price one has ever garnered, according to the records at Sports Car Market, was $4.62 million paid in early 2012 at Gooding & Company's Scottsdale auction. This example, however, stands to far surpass that amount to set a new record. It's just one of several notable lots consigned for the Driven By Disruption event, set to take place on December 10 in New York. Alongside it, RM has the Lamborghini Concept S (valued at over $2.4 million), a 1962 Aston Martin DB4 GT Zagato (over $16m), and a 1956 Ferrari 290 MM driven by Juan Manuel Fangio ($28m). In short, it ought to be a significant sale, and we'll report the results once they're in.
