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.

8 cars we're most looking forward to driving in 2015

Now that 2014 is officially in the books, it's time to look ahead. And following our list of the cars we liked best last year, we're now setting our sights at the hot new metal that's coming our way in 2015. Some of these, we've already seen. And some are still set to debut during the 2015 auto show season. But these are the machines that keep us going – the things on the horizon that we're particularly stoked to drive, and drive hard. Jeep Renegade Not the Chevrolet Corvette Z06. Not the Ford Mustang GT350. Not the new John Cooper Works Mini. Nope, I'm looking forward to the adorable, trail-rated Jeep Renegade. And that's because I really, really, really like our long-term Jeep Cherokee Trailhawk. I do not, however, care too much for the Cherokee's looks, and I really don't like its $38,059 price tag. The Renegade Trailhawk, meanwhile, promises much of the same rough-and-tumble character as its big brother, but at what we expect will be a more reasonable price (I'm personally wagering on the baby Jeep's off-road model starting at no more than $23,000). With a 2.4-liter four-cylinder and a nine-speed automatic, it should also be a bit easier to fill than the V6-powered Cherokee. Also, I can't help but love the way the Renegade looks. It's like someone took a Wrangler, squished it by 50 percent and then handed it off to George Clinton for a healthy dose of funk. The interior, with its bright, expressive trims and color schemes should also be a really nice place to spend some time. I'll be attending the Renegade's launch later this month, so I'll have a much shorter wait than my colleagues. Here's hoping the baby Jeep lives up to my expectations. – Brandon Turkus Associate Editor Mazda MX-5 Miata Here's an uncomfortable truth: I'd rather spend a day driving a properly sorted Mazda MX-5 Miata of any generation on a winding road than I would nearly any other vehicle, regardless of power, price or prestige. It's not just that I prize top-down driving and enjoy the Miata's small size because it gives me more road to play with. I just find there's more motoring joy to be had with high-fidelity handling and an uncorrupted car-to-driver communication loop than I do with face-distorting power or grip – let alone valet-stand gravitas. But perhaps most of all, I love Miatas because they can deliver that level of feedback and driver reward at modest speeds that won't put the locals on edge or endanger lives – you can use more of the car more of the time.

Lewis Hamilton wins Spanish Grand Prix, takes 17-point lead over Vettel

BARCELONA, SPAIN – Lewis Hamilton won the Spanish Grand Prix in a commanding Mercedes one-two on Sunday to stretch his Formula One lead over Ferrari's Sebastian Vettel, who finished fourth, to 17 points. The victory, in a race that stayed dry despite the threat of rain, was the Briton's second of the season, 64th of his career and third at the Circuit de Catalunya. It also set a record, one that Hamilton had previously shared with seven times champion Michael Schumacher, of 41 wins from pole position. "This is more like it, let's keep this up," Hamilton told his celebrating team over the radio as he swept past the checkered flag. "Today the car and myself, I felt that synergy which I hadn't been feeling for the whole year," he added in a pre-podium interview after parking up in pit lane. "It's a good feeling." Hamilton's win followed on from the lucky victory that fell into his lap in Azerbaijan two weekends ago, but Sunday had nothing to do with chance and all to do with the champions being back to their best. He now has 95 points to Vettel's 78 after five rounds of the 21-race championship. Mercedes regained the lead in the constructors' standings and are now 27 points clear of Ferrari who had 2007 world champion Kimi Raikkonen retire from the race. Finland's Valtteri Bottas was second, a hefty 20.5 seconds behind, with Dutch 20-year-old Max Verstappen completing the podium for Red Bull – his first of an incident-filled season. Australian Daniel Ricciardo was fifth for Red Bull, ahead of Denmark's Kevin Magnussen for Haas and Spaniards Carlos Sainz (Renault) and Fernando Alonso (eighth for McLaren). Sainz's points lifted Renault ahead of McLaren and into fourth place by a single point. Mexican Sergio Perez was ninth for Force India and Monegasque rookie Charles Leclerc took the final point for Sauber. While Hamilton pulled away cleanly at the start, and Vettel passed Bottas into the first corner for second place, there was carnage behind as Romain Grosjean spun his Haas in a cloud of smoke. The Frenchman then collected the Renault of Nico Hulkenberg and Pierre Gasly's Toro Rosso in a major smash, fortunately without injury, that brought out the safety car for the first six laps. Stewards gave him two penalty points and imposed a three-place grid drop for the next race in Monaco.
