2015 Bahrain F1 Grand Prix puts a dark horse in the desert [spoilers]

Ferrari's Kimi Raikkonen had said after Malaysia that Ferrari can challenge Mercedes-AMG Petronas purely on pace, beyond the scope of tire wear, in the dry. We didn't see that in China, where Lewis Hamilton easily kept everyone behind and Ferrari's Sebastian Vettel only got close to Mercedes' Nico Rosberg when Rosberg slowed down to conserve his tires. But the Iceman's words seemed prescient during qualifying for the Bahrain Formula One Grand Prix. At the front, nothing has changed so far this year: four races, four pole positions for Lewis Hamilton. Instead of teammate Rosberg next to him, though, he'll look over to see the scarlet Ferrari of Vettel, who took advantage of Rosberg's cautiousness to snatch second place on the grid. In Q2, Rosberg tried to conserve the tires he'd start the race on and said he couldn't get into a groove in Q3, putting in a time 0.147 seconds slower than Vettel. The second Silver Arrows will share his row with the second Ferrari, Raikkonen – yet again – saying he might have left some time on the table during his hot lap but getting around just one tenth off Rosberg's time. Williams is established as the best of the rest behind two teams this year instead of just one last year, Valtteri Bottas claiming fifth ahead of Felipe Massa. Daniel Ricciardo of Infiniti Red Bull Racing said he wants to fight with the Williams', he'll be helped with a good start off the line for the first time this year. Nico Hulkenberg got Force India into Q3 for the first time since the Italian Grand Prix last year and into eighth on the grid, ahead of Carlos Sainz in the Toro Rosso and Romain Grosjean putting in another excellent day's work for Lotus. Come race time, it turned into Mercedes power against Ferrari strategy. When Sky F1 commentator Martin Brundle talks about the Mercedes-AMG Petronas team he often mentions how their engine advantage leads to other advantages throughout the car. Not having to use aerodynamic changes to make up for power unit deficiencies, for instance, means they can run the aero setup they want, which optimizes speed and tire wear throughout a lap. It equates to advantage on top of advantage on top of advantage. That's where Lewis Hamilton is right now, so fundamentally dialed in to his car and his racing that he run the races he wants to run. From the front spot, the Brit ripped off another perfect start and led the field into Turn 1, relinquishing the lead only during pit stops.

2015 Mercedes-Benz CLS400 [w/video]

Rocky IV debuted in 1985 but it was a few years later that I first watched it, on video. I loved every second of that terrible movie. I loved Drago's super-high-tech demonstration of punching power. I loved Rocky training in a Russian barn, with ropes, and yokes, and wagons. But mostly I loved Brigitte Nielsen. My 10-year-old brain sweated her impossible combination of curves and sharp edges, demure eyes, and sculpted bone structure. The perfect woman, but evolved by the power of the dark-hearted Soviet Union (or Denmark, whatever, I was ten). Red Sonja has a lot in common with the latest version of the Mercedes-Benz CLS, as I see it. Mercedes created a new market niche with its first four-door coupe, a sedan so well-proportioned, flowing, and femininely curved that it could pull off its inaccurate moniker. The third evolution of the CLS you see here has Nielsened up the shape into something altogether more angular and edgy, but like 1985's Brigitte, retains an undeniable sex appeal. It's a more opinionated piece of auto design than was the original CLS. And also a car that bifurcates the space between luxury coupe and luxury sedan. Ludmilla Drago would undoubtedly understand. Driving Notes For the base engine of a 4,200-pound car, the CLS400's two-turbo V6 does better than just get out of its own way. The full 354 pound-feet of torque is available way down at 1,600 revs, and plateaus until 4,000, giving you a fat band in which to call up power. Acceleration is available in the form of a quiet, gracious, but not aggressive push at just about every speed. From inside the cabin, the engine and exhaust noises are pleasantly rumbling, though muted. But do yourself a favor and try not to listen to the CLS tick over while standing around the driveway. When the car first pulled up in mine, warm from some 40 miles of highway, it still sounded an awful lot like a 2.0T on a mid-March morning. Not to belabor the Brigitte metaphor, but I found as much Neilsenian dichotomy in the ride and handling as I did the exterior styling. Especially with Mercedes' 4Matic system spreading out the grip, I found the CLS to be sharp when pushed, and rather excellent in terms of making quick corrections while under a cornering load. And yet, you've got to push through an initially soft suspension response to reach that hard edge. The CLS will initially resist being tossed around a winding backroad, but press on and she'll do as you ask.

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.
