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 FWD platform to last until 2018, convertible and two-seater future uncertain

Mercedes-Benz seems to be expecting a lot of success from its front-wheel-drive CLA-Class. Automotive News is reporting that the sub-C-Class sedan could grow when its second generation arrives in 2018.
The current FWD platform for MB underpins the CLA, the B-Class, the GLA-Class, and the A-Class. The B-Class will arrive in North America as an EV for spring of 2014, while the production GLA crossover will arrive three to four months after that. The five-door A-Class won't be crossing The Pond. Sad faces all around.
According to AN, another model will be based on the front-drive architecture, but it won't be coming to the US market. Set to arrive next year, rumors are that it'll be a wagon version of the CLA, sort of like the ill-named five-door CLS Shooting Brake that is also a Europe-only item.

Car technology I'm thankful and unthankful for

The past few years have seen a surge of tech features in new vehicles — everything from cloud-based content to semi-autonomous driving. While some of it makes the driving experience better, not all tech is useful or well thought out. Automakers who are adept at drivetrains, ride quality and in-cabin comforts often fail at infotainment interfaces and connectivity. From testing dozens of vehicles each year and in the spirit of gratitude, here are three car tech features I'm thankful — and a trio I could live without. Thanks Connected search: This seems like a no-brainer since everyone already has it on their smartphones, but not all automakers include it in the dashboard and as part of their nav systems. The best ones, such as Toyota Entune, leverage a driver's connected device to search for a range of services and don't charge a subscription or require a separate data plan for the car. I also like how systems like Chrysler Uconnect use Yelp or other apps to find everything from coffee to gas stations and allow searching via voice recognition. Apple CarPlay and Android Auto: It took two of the largest tech companies to get in-dash infotainment right. While they have their disadvantages (you're forced to use Apple Maps with CarPlay, for example), the two smartphone-integration platforms make it easier and safer to use their respective native apps for phoning, messaging, music and more behind the wheel by transferring a familiar UI to the dashboard — with no subscription required. Heated seats and steering wheels: I really appreciate these simple but pleasant features come wintertime. It's easy to get spoiled by bun-warmers on frosty mornings and using a heated steering wheel to warm the cold hands. I recently tested a 2018 Mercedes-Benz E400 Coupe that also had heated armrest that added to a cozy luxury experience. Bonus points for brands like Buick that allow setting seat heaters to turn on when the engine is remotely started. No thanks Automaker infotainment systems: Automakers have probably poured millions into creating their own infotainment systems, with the result largely being frustration on the part of most car owners. And Apple CarPlay and Android Auto coming along to make them obsolete. While some automaker systems, such as Toyota Entune and FCA's Uconnect, are easy and intuitive to use, it seems that high-end systems (I'm looking at you BMW iDrive and Mercedes-Benz COMAND) are the most difficult.
