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.

2016 Mercedes-Benz C450 AMG Sport bridges the gap between C300 and C63

Mercedes-Benz is looking to its new C-Class for the second member of its new AMG Sport line, unveiling the C450 AMG 4Matic at today's 2015 Detroit Auto Show. Like the GLE450 AMG Coupe that debuted in early December, this particular C-Class bridges the gap between the standard C300 and the new Mercedes-AMG C63. Considering this, the C450 builds on the standard C400's 3.0-liter, twin-turbocharged V6, rather than getting a bespoke, high-performance engine. Output is up from 329 horsepower to 362 ponies, while torque is turned up from 354 pound-feet to 384 lb-ft. The result of these upgrades is a zippy 0-60-mile-per-hour sprint of 4.9 seconds and an electronically limited top speed of 155 mph. Those figures are identical to the Audi S4, while the BMW 335i xDrive is just a smidge quicker to 60, getting there in 4.8 seconds (the Bimmer is, however, limited to just 130 mph). Shuffling the 3.0-liter's grunt to a 4Matic all-wheel-drive system is the responsibility of Mercedes 7G-Tronic automatic gearbox that, despite not being a member of AMG's Speedshift dual-clutch family, still has its own mind for performance. Along with a quick-shifting, automatic Sport Plus mode, the C450 has a full manual shifting mode that, notably, will not automatically upshift, even when the engine is bouncing off the rev limiter. The C450 AMG hasn't only had its straight-line abilities boosted. Mercedes saw fit to include an AMG adaptive sport suspension with three-stage adjustable dampers, which have been pilfered from the C63 AMG. Paired with the aforementioned all-wheel-drive system, which can send up to two-thirds of its power to the rear axle, it's a fair to say this particular sedan should be one of the brand's more agile and entertaining. Beyond the mechanical bits, Mercedes has beefed up the exterior and interior aesthetics for its second AMG Sport model. The exterior has been touched up with new, staggered 18-inch, five-spoke wheels (or optional 19s), a more aggressive front fascia, a new rear bumper with a matte iridium diffuser, distinctive AMG badges and plenty of chrome and gloss-black elements. The cabin, meanwhile, is home to black MB Tex upholstery with red contrast stitching on the dash and doors, while AMG-specific upholstery lines the sport seats. The flat-bottomed, three-spokes steering wheel, meanwhile, is finished in Nappa leather. We'll have more on the 2016 C450 AMG Sport, including live images, coming soon from the floor of the 2015 Detroit Auto Show.

Lewis Hamilton takes pole as Mercedes speed stuns rivals

MELBOURNE, March 16 (Reuters) - Formula One champion Lewis Hamilton blazed to a record-extending eighth pole and sixth in succession at the Australian Grand Prix on Saturday to lead Valtteri Bottas to a Mercedes sweep of the front row of the grid. Hamilton struggled with a brake problem during the frenetic final session at Albert Park but edged his Finnish team mate by 0.112 seconds with a searing second lap of one minute 20.486 seconds that set a record at the lakeside circuit. The one-two punch by Mercedes left Ferrari and their championship rivals stunned, with Hamilton's chief challenger Sebastian Vettel, who qualified third, more than seven-tenths of a second off the five-times champion's pace. "Oh man, I'm shaking it was so close out there," Briton 34-year-old Hamilton said after extending his pole record to 84 on a warm, sunny afternoon in Melbourne. "Coming from winter testing, we had no idea where we would be. We were hoping to be where we are ... Valtteri did an exceptional job out there, it was very close." Hamilton matched Ayrton Senna and Michael Schumacher for the record number of poles at a single race track. Senna took his eight at Imola, with Schumacher dominating the Suzuka circuit. Four-times champion Vettel, bidding for a third successive win at Albert Park, was separated from his new team mate Charles Leclerc by fourth placed Max Verstappen of Red Bull. It would have felt like 'deja vu' for Ferrari, having trailed Mercedes by nearly seven-tenths of a second in qualifying at last year's race. "Certainly Mercedes are the clear favorite," Vettel told reporters with a touch of resignation. "I'm certainly surprised (by their pace), I think everybody is, probably even themselves." "I think, there is still a bit of margin (to improve) but certainly the gap is there today, and it was a surprise," the four-times champion told reporters. "We didn't expect it coming here but now it is that way. ... Obviously there is a lack somewhere, because we are too slow – but didn't feel like it." German Vettel's new team mate Charles Leclerc qualified fifth fastest behind Red Bull's Max Verstappen but the highly regarded 21-year-old was harder on himself than the car. "I'm not happy with myself. I didn't do the job in Q3, which is a shame," said the Monegasque, who locked up in turn one of a "messy" second lap.
