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 EQC vs. Jaguar I-Pace vs. Tesla Model X: How they compare on paper

The Mercedes-Benz EQ line is officially alive and kicking, with the reveal of the EQC electric crossover. It joins a segment that, while still in its infancy, seems ready to take off. Mercedes lists as the EQC's competitors the Jaguar I-Pace, The Audi E-Tron Quattro and the BMW iX3. While we've seen all of these, at least in concept or pre-production form, only one — the Jag — has actually been launched in production form. We've seen a concept and subsequent spy shots of the iX3, and the Audi EV will get its official specs publicized later this month. One electric SUV Mercedes didn't specifically call out was the Tesla Model X. As such, we've decided to compare on paper the Mercedes-Benz EQC 400, the Jaguar I-Pace S and the Tesla Model X 75D: All three are dual-motor EVs, though the Tesla is the longest and tallest. The EQC has the most power, but it and the Model X's 4.9-second 0-60 times fall short of the I-Pace. It also has the lowest top speed and electric driving range. (Mercedes sent us an updated range figure, but it's using the generous and largely outdated NEDC cycle; we're still waiting on an EPA rating.) We'll be interested to see how much the Mercedes weighs. Mercedes hasn't divulged the price of the EQC yet, but we imagine it'll fall pretty near to the $70,000 mark. As for Audi, we'll revisit this comparison after those details are made available on September 17. If you're interested in some other EV comparisons, we have a couple others that we published to compare the I-Pace to premium Teslas, as well as against other less-expensive EVs. If you want to learn more about these EVs, and compare them with other cars, be sure to check out our Car Finder and comparison tools.

2015 Belgian Grand Prix is a return to scheduled programming

With summer intermission over, the second half of the Formula One season commenced in the Belgian countryside at Spa-Francorchamps. After qualifying, it looked a lot like the first half of the season with just a few minor changes. Lewis Hamilton was even more dominant in his Mercedes-AMG Petronas than usual, regularly taking half a second out of his teammate in just the middle sector of the circuit. Teammate Nico Rosberg tightened it up a tad for his final hot lap, but Hamilton still took pole by 0.45 seconds ahead of Rosberg in second. With his Williams back at a power track, Valtteri Bottas got himself up to third, although more than a second behind Hamilton. Romain Grosjean in the Lotus in fourth had his best qualifying performance since his fourth-place grid spot at the 2013 US Grand Prix. This was a huge boon for Lotus, the team facing another financial issue off track that threatened to have its cars impounded as soon as they left the circuit. Grosjean had to have his gearbox changed before the conclusion of six races, however, so the five-spot penalty meant he'd actually line up ninth for the race. Sergio Perez put the Sahara Force India in fifth, where we're more used to seeing his teammate Nico Hulkenberg, just ahead of Daniel Ricciardo in the Infiniti Red Bull Racing in sixth. Felipe Massa got the second Williams in seventh, in front of the second Lotus of Pastor Maldonado in eighth. Then came the first and only Ferrari in the top ten, Sebastian Vettel qualifying ninth after a disappointing Saturday for the scuderia; teammate Kimi Raikkonen suffered gearbox issues and qualified way down in 16th. Carlos Sainz took tenth in the Toro Rosso. A new start procedure in Belgium meant drivers had to handle clutches on their own, without the engineers finely tuning bite points between the garage and the start line. That was in conjunction with another rule limiting the kinds of radio messages possible between engineers and drivers, aiming to put more of the car in the drivers' hands. After an aborted start when Hulkenberg's car quit while sitting on the grid, Hamilton made the most of the new procedure. His start wasn't amazing but he beat everyone else off the line, while those behind were alternately getting bogged down or leaping ahead. Midway through the first lap the top ten was Hamilton, Perez, Ricciardo, Bottas, Rosberg, Vettel, Maldonado, Grosjean, Massa, Marcus Ericsson. At the end of 43 laps, Hamilton would still be in the lead.
