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.

Aston Martin and Mercedes-AMG formalize technical partnership

The development of a partnership between Mercedes-Benz and Aston Martin has been a long time coming. The news dates back to 2008, and over the five years since was supposed to lead to a rejuvenation of both the Maybach and Lagonda brands. That program ultimately fell apart, but the tie-in was forged afresh in July when the two automakers signed a letter of intent over a renewed partnership. And now that partnership has been formalized.
In a deal just announced, Mercedes-AMG will build a new V8 engine for Aston Martin that will power a new generation of luxury GTs for the British marque, presumably to replace the 4.7-liter V8 in the Vantage. The relationship appears to be similar to the one already in place between AMG and Pagani, only in this case, will involve Daimler taking as much as a five-percent stake in Aston Martin and an observer seat on Aston's board.
The technical partnership is also set to lead to the supply of electric and electronic systems, and could incorporate "additional areas of cooperation in the future." Whether that will include a fresh attempt at reviving Lagonda remains to be seen, as does the future of Aston's long-serving, Ford-based 6.0-liter V12 engine. But for now you can read the full announcement below.

2016 Mercedes-AMG G65 coming to US this fall, priced from $217,900*

The top end of the luxury SUV market keeps edging northwards. Where the prospect of spending six figures on an off-roader once seemed unthinkable, a new class at the top end of the segment has emerged with prices exceeding $200k. And now American buyers will have another choice on their hands with the arrival of the Mercedes-AMG G65. The flagship model of the Gelandewagen range, the G65 is based on Benz's immortal SUV that's been produced in Graz, Austria, since 1979 and (officially) arrived in the US in 2002. But while the G-Class has been offered in a number of specifications even here in America – up to and including the eight-cylinder G63 AMG – the top-of-the-line G65 was kept away from these shores. But now the German automaker has announced it's bringing its ultimate sport-ute to American showrooms. Distinguishing the G65 from 'lesser' G-Wagens is its 6.0-liter twin-turbo V12 – the same essential unit that already powers the S65 coupe and sedan, SL65 roadster and the Pagani Huayra – producing in this application 621 horsepower and 738 pound-feet of torque. That's said to be enough to shuffle the big ute up to 60 in just 5.3 seconds. Of course all that power and prestige comes with a price, and as you might have guessed, it's astronomical: $217,900 plus $925 delivery, to be specific. In that ballpark, it'll be tangling with the new Range Rover SVAutobiography and the upcoming Bentley Bentayga. Not even the top-of-the-line, $157k Porsche Cayenne Turbo S wears that high a price tag. Look for the Mercedes-AMG G65 to reach showrooms in November, and check out the ever-so-slightly facelifted G-Wagen in our gallery above, live from New York.

Starting at an MSRP of USD $217,900, this model joins the G550 and G63 AMG in the U.S. lineup in November 2015. It is also the fourth exclusive AMG model priced above $200,000: SL65 ($215,250), S65 sedan ($222,000), and S65 Coupe ($230,900). Powered by a V12 bi-turbo engine, the G65 AMG delivers 621 hp and 738 lb-ft. of torque, with an estimated 0-60 mph acceleration in 5.3 seconds. The G-Class is the only off-road vehicle in its class to combine the electronic traction system 4ETS with a transfer case and three 100% differential locks.
