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.

CES 2022 was huge for EVs | Autoblog Podcast #711

In this episode of the Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Senior Editor, Green, John Beltz Snyder. CES took place this week, and there were some nice electric surprises from automakers, especially General Motors. John has been driving the Ram 1500 Power Wagon, as well as what seems to be its polar opposite, the electric Mini Cooper SE. Greg talks about the differences between the Acura TLX A-Spec long-termer (which is back in the shop) and the Type S loaner that's filling in for it. John's also got some interesting thoughts on leather interiors. Finally, the editors reach into the mailbag and help a repeat customer decide on a suitable replacement for a 2008 Lexus GX 470 in this week's Spend My Money segment.

Mercedes-Benz to build new ML coupe-crossover in Alabama in 2015

Mercedes-Benz will expand its factory in Tuscaloosa, AL, to build the ML Coupe, a new crossover that will join its lineup in 2015. Mercedes will also ramp up production to build facelifted versions of the M-Class and GL-Class SUVs, lifting the factory's total production capacity to about 300,000 units annually in 2015. It made 185,000 vehicles in 2013. In addition to SUVs, the Tuscaloosa site also makes the C-Class sedan.
The plans come as part of Mercedes' strategy to capitalize on Americans' increasing demands for SUVs. The company said the SUV market was up 12 percent in first half of 2014, and expects it to grow at twice the rate of the regular market in 2015 and 2016.
