Mercedes rolls out the long red carpet for new Maybach S600 Pullman [w/video]

Remember when the S-Class was the S-Class and that was it? The pinnacle of the Mercedes-Benz lineup, at least as far as sedans were concerned. But those days are long behind us. Now there's a coupe as well (bringing the former CL back into the fold), a convertible on its way, the uber-luxe Maybach limo and this: the new Pullman. The creme de la creme of the Silver Star range, His Excellency Field Marshall Dr. Mercedes-Maybach S600 Pullman Dada – as it's known in full, at least with the twelve-cylinder engine – is... well, it's enormous. It's bigger than the old Maybach 62 it essentially replaces and bigger even than an extended-wheelbase Rolls-Royce Phantom. And why would you need a vehicle so large? Well, you wouldn't. And neither would we. But there are some, shall we call them "unelected heads of state" who would accept no less. They're the customers who favored the original, and 50 years later, they're the ones who'll be snapping up the new one. (The little wavy flags on the front fenders are optional.)

Mercedes-AMG GT and C63 to serve as F1 safety, medical cars

Mercedes has spent nearly 20 years providing the safety and medical cars for Formula 1, so it was hardly a shock when the company announced that the new Mercedes-AMG GT and C63 AMG S Estate would serve as ushers in the F1 circus. The two turbocharged monsters replace the old SLS AMG safety car and C63 AMG wagon medical car, which have served in one trim or another since 2010 and 2008, respectively. The biggest change for either car is, of course, the lightbar. It's been mounted atop a carbon-fiber hoop on the AMG GT that Mercedes says optimizes airflow to that big rear wing. Meanwhile, the location of the lights was confirmed via wind tunnel testing. In the cockpit, two iPads allow the AMG GT's passenger, fuel analyst Peter Tibbetts, to monitor the race's world feed while also keeping an eye on race data. The tablets stay connected via an in-car, wireless internet connection. Changes for the C63 S wagon are less extensive. It gets a lightbar and the usual signaling systems in the headlights and taillights, while the cargo compartment includes both a respirator and a defibrillator, to manage more serious medical emergencies. As with the AMG GT, the C63 is finished in F1's traditional silver safety/medical car livery. Beyond these changes, both vehicles are just as potent as those that can be purchased at dealers. Both cars feature a 4.0-liter, 510-horsepower, twin-turbocharged V8, while a seven-speed AMG Speedshift transmission dispatches the grunt with lightning-quick shifts. So equipped, the AMG GT will hit 60 in 3.8 seconds and the C63 can get there in 4.1 seconds. Check out the full gallery of both cars, decked out in their F1 liveries, available up top.

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.
