Mercedes-AMG considering turbo fours, hybrid sixes for future performance sedans

Think of the letters AMG and you'll probably end up picturing a performance sedan with a big V8. Such has become, after all, the Mercedes turning division's calling card. But with the introduction of its 2.0-liter turbo four, AMG is working at turning that notion on its head.
The highly potent engine produces 355 horsepower and is presently installed in the A45 AMG hatchback, CLA45 AMG sedan and GLA45 AMG crossover, giving Benz's smallest family a full range of performance models. But that might not be the full extent of the high-strung four-pot's use.
Speaking with AMG boss Tobias Moers, Britain's What Car? magazine reports that Affalterbach is considering slotting the same engine into larger models, particularly performance sedans like the C-Class. As we recently reported, Mercedes is already preparing to up the power from the turbo V6 in the C400 to slot a C450 Sport in below the C63 AMG. The C450 is expected to offer around 367 horsepower where the CLA45 AMG et al pack 355, but the lighter weight of the four-cylinder engine would likely offset the truancy of those extra dozen horses. Of course such a prospect would be much further down the pipeline than the C450 Sport which is expected to arrive much sooner.

Daimler could sell off Li-Tec's EV battery business

Five-plus years may have been about enough time for Daimler AG to know whether it wanted to be in the battery-pack production business. The Mercedes-Benz parent may stop making electric-vehicle batteries and ultimately sell its Li-Tec battery-cell factory in Germany within two years, according to Bloomberg News which cites Manager Magazin. The beneficiary may be LG Electronics, which would likely take over battery-production duties for models such as Daimler's Smart ED battery-electric vehicle. Daimler is taking a number of steps to improve profit margins, which are thinner than those of its German rivals like BMW. Like its German competition, the company has lagged behind companies such as Nissan, Renault and Tesla Motors in terms of aggressively pursuing growth via plug-in vehicle sales. Daimler spokesman Hendrik Sackmann, in an e-mail to AutoblogGreen, would only say that the battery business is growing "rapidly" and that Li-Tec is developing "according to our plans." "Regarding Li-Tec, we are working on a concept for the future line-up," he added. "The battery cells for the successor of the Smart electric drive won't be provided by Li-Tec." Daimler in 2008 launched Li-Tec as a joint venture with Evonik, though Daimler recently put plans together to buy out Evonik's 50-percent share of Li-Tec, Bloomberg reported last month. Evonik's role was manufacturing electrodes and separators for batteries. Daimler also said last fall that it was looking to cooperate more extensively with Tesla in regards to electric vehicle development. The two companies first said they'd work together in 2009.

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.
