Nissan edges out Tesla for most ZEV credits sold in California

When it comes to California zero-emissions vehicle (ZEV) credits last year, Nissan was selling and Mercedes-Benz was buying. The California Air Resources Board (CARB) put out its ZEV-credits numbers for the year that ended September 30, which is why we now know that Nissan, maker of the battery-electric Leaf, transferred 663.6 ZEV credits out of its account last year. That just edged out the 650.195 credits that Tesla sold. Chrysler's Fiat affiliate was a distant third, but its limited-production Fiat 500E was still able to generate some ZEV credits and then transfer out 235.2 of them. We don't know how much the buyers paid for these credits, since those details are kept private. It's an ever-changing rulebook over at CARB, anyway. On the flip side, Mercedes-Benz had to buy 663.6 ZEV credits in order to comply with clean vehicle-sales mandates in the most populous US state, indicative of the German automaker's gas-guzzling tendencies. Honda has cars that get better fuel economy than your average Benz, but its plug-in vehicles represent just a fraction of total sales and so it had to shell out for 542.5 ZEV credits. Chrysler-Fiat basically tread water, since the 237.8 ZEV credits it required for compliance canceled out gains on the other side of the ledger. Those Dodge Ram pickup trucks don't exactly help matters. Last year, Tesla sold the most ZEV credits while GM purchased the most. Overall, Californians bought about 3.5 million vehicles for the year that ended September 30, including 38,000 battery-electric vehicles, 30,000 plug-in hybrids and 570,000 conventional hybrids. The longstanding ZEV program means that California now has more than 100,000 ZEVs on its roads. Read this for more details on ZEV credit transfers in California.

2014 Mercedes SL and SLK add small expansion to Takata airbag recall

Mercedes-Benz is the latest automaker to be affected by Takata's massive airbag recall. The company has announced a voluntary recall campaign on a small number of model-year 2014 SLK- and SL-Class roadsters.
In Mercedes' case, 300 vehicles are affected, 200 of which are in the hands of customers. According to spokesperson Donna Boland, the affected roadsters were built between March and April of this year.
The issue, which is apparently the fault of one of Takata's subcontractors, rests with some improperly installed fasteners, which could keep the airbag from performing the way it's supposed to. According to Boland, Mercedes isn't sure what, if any, injuries the recalled airbags could cause, but simply claims there's an increased risk in these particular vehicles. There's been no reported instances of the faulty airbags deploying on a customer and the original issue was found in a production test.

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.
