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.

Best luxury SUVs of 2022 and 2023

Once upon a time, the idea of a luxury SUV meant a Range Rover, and even that was pretty agricultural by modern standards. Then Jeep Grand Cherokees and Ford Explorers started offering fancy, range-topping versions followed soon by Lexus, BMW and Mercedes dipping their toes in the water. And then the floodgates opened. Today, there is a staggering number of luxury SUVs available in every shape, size and price point. There are electric luxury SUVs like the Tesla Model X and Jaguar I-Pace, as well as gas-swilling, high-performance SUVs like the BMW X5 M and Cadillac Escalade V. Sports car makers Porsche, Aston Martin and Lamborghini have even dived in.  But of this great many, which are the best luxury SUVs? We sat down, scoured our reviews, took some votes, had some discussions and came up with the luxury SUVs we view as the best. They are listed alphabetically within the six segments listed below.  Best Subcompact Luxury SUV   |   Best Compact Luxury SUV   |   Best Midsize Luxury SUV (Two-Row) Best Midsize Luxury SUV (Three-Row)   |   Best Flagship Luxury SUV (Two-Row)   |   Best Flagship Luxury SUV (Three-Row)  Best subcompact luxury SUVs Mercedes-Benz GLB-Class Why it stands out: Outstanding space and versatility; legit luxury interior; amusing GLB 35 versionCould be better: Overwhelming and confusing tech interface Most subcompact luxury SUVs are a dubious value, with cramped interiors of marginal quality and unrefined driving dynamics. You'd be much better off paying less money for a loaded, non-luxury compact SUV. The Mercedes GLB is different, though. Its boxy design provides space few other subcompact SUV can match (luxury or otherwise), while its cabin design and feature content are in keeping with pricier Mercedes models. The quality's not exactly up to GLC standards, nor is driving refinement, but the difference is appropriate for how much you're saving and still perfectly acceptable. There's nothing dubious about buying a GLB.     Volvo XC40 Why it stands out: More features for the money; spacious and versatile interior; distinctive design; electric versionCould be better: Fuel-efficient base engine only available with FWD Most subcompact luxury models feel a bit like cheap knockoffs of their bigger, pricier brand mates. The XC40, by contrast, is a break from the Volvo norm in a good way.

How chasing Ferrari improved Aston Martin, with help from Mercedes-Benz

GAYDON, England — After decades of ups and downs, British carmaker Aston Martin Lagonda is charting a more efficient and profitable way forward, leaning on technology from shareholder Mercedes-Benz to make the costly leap to electric vehicles (EVs). Less than two years after billionaire Lawrence Stroll drove to the rescue of James Bond's car brand of choice, Aston Martin has undergone a manufacturing makeover to lift margins and help it become more like rival Ferrari. Stroll, Aston Martin's largest shareholder and executive chairman, who is also an avid fan of Ferrari, says after vehicle sales jumped 82% in 2021 the carmaker's transformation to long-term profitability is well under way, with new cars coming and funding secured through 2025. But analysts say Aston Martin, which has gone bust seven times since it was founded in 1913 and has flirted with death as often as Agent 007, is still burning through piles of cash. Some question its ability to generate Ferrari-like sales to fund the vast cost of electrification. "It's precarious and it is possible for this company to go bust," said Redburn equity research analyst Charles Coldicott. "I don't think it's a controversial thing to say even though Aston wouldn't like to hear it." Asked to comment on perceptions of a shaky future, an Aston Martin spokesman reiterated Stroll's view that the carmaker is well on the way to long-term profitability and that it has adequate access to cash. On a tour of the carmaker's Gaydon factory, Tobias Moers, formerly head of Mercedes' high-performance AMG brand and Aston Martin chief executive since August 2020, rattles off a list of moves including cutting one of two assembly lines and bringing more bespoke items like seats in-house. Perhaps the biggest shift has been to focus on higher-value customer-driven and customized orders — a big part of Ferrari's success — rather than over-producing and churning out sports cars wholesale, which then had to be discounted. "When I came in, the company was manufacturing-dominated instead of engineering-led, which for an auto luxury business is insane," Moers said. "In a company this size, you need maximum flexibility and agility." Moers has cut Aston Martin's inventory to 600 sports cars from 2,000 — its cars sell for an average of around 150,000 pounds ($195,750) — and customized orders now account for 50% of sales versus 6% when he joined the firm. At that point, the carmaker was in trouble after a disastrous 2018 public listing.
