Ford files patent for 11-speed transmission

The automatic transmission seemed limited to three or four gears for decades, and then the automotive world slowly started to see more ratios becoming available. Today, seven-, eight- or nine-speed gearboxes have become rather common. Ford even has an automatic with 10 gears on the way for the future F-150 Raptor. The Blue Oval might not be done yet, though, because the company also now has a patent on an 11-speed box. The filing, which was discovered by AutoGuide, says this idea "produces eleven forward speed ratios and one reverse speed ratio by selective engagement of three shift elements in various combinations," and the company outlines three different ways of making this possible. The advantage of adding one more ratio is that the gearbox should be able to keep the revs in the ideal portion of the engine's torque curve even longer. Obviously, automakers patent ideas constantly, and applying for one is no guarantee that the tech ever arrives on the market. Conversely, these documents provide a tiny glimpse at one of the brand's focuses of development. If you're mechanically minded or just curious, you can read the entire application here for the technical nitty-gritty.

New car market raining on convertibles' parade

Whether fitted with soft or hard folding lids, today's droptops are better than ever for year-round motoring. Advancements in power top mechanisms, sealing, aerodynamics, structural rigidity, rollover safety and creature comforts like heated and cooled seats mean that modern convertibles are more versatile and better to drive than ever before. Yet the segment's sales took a dive during the recession and haven't come back, Automotive News reports.
Part of that is because automakers are looking at today's more sensible buyers and simply not developing as many new models, and that lack of fresh iron is curbing sales. AN cites R.L. Polk data which notes that only about one percent of new vehicles registered in the US last year had tops that folded. Back in 2009, it was 1.4 percent, and it was 2 percent in 2006. All-in, some 151,636 convertibles were registered in 2012. That's more units more than were registered in each of the past three years, but the market has also grown as the economy has picked up speed, and as a percentage of new vehicles purchased, convertible sales are lagging.
Thus far in 2013, the Ford Mustang is America's top-selling convertible, with 6,421 units registered through the end of April, followed by its rival, the Chevrolet Camaro, at 4,751 units. The Volkswagen Beetle isn't far behind, with 4,305, but from that point, it's a steep drop off to the fourth-place Mercedes-Benz SL-Class and its 2,380 sales.

Child cobalt miners: Automakers pledge ethical minerals sourcing for EVs

BERLIN - Leading carmakers including Volkswagen and Toyota pledged on Wednesday to uphold ethical and socially responsible standards in their purchases of minerals for an expected boom in electric vehicle production. Demand for minerals such as cobalt, graphite and lithium is forecast to soar in the coming years as governments crack down on vehicle pollution and carmakers step up their investments in electric models. To cover its plans for more than 80 new models by 2025, Volkswagen alone is looking for partners in China, Europe and North America to provide battery cells and related technology worth more than 50 billion euros ($59 billion). Talks with major cobalt producers, including Glencore, at VW's Wolfsburg headquarters last week ended without a deal. More than half of the world's cobalt comes from the Democratic Republic of Congo, a country racked by political instability and legal opacity, and where child labor is used in mines. On Wednesday, a group of 10 leading passenger-car and truck manufacturers announced an initiative to jointly identify and address ethical, environmental, human and labor rights issues in raw materials sourcing. The partnership dubbed "Drive Sustainability" consists of VW, Toyota Motor Europe, Ford, Daimler, BMW, Honda, Jaguar Land Rover, Volvo Cars and truckmakers Scania and Volvo. The alliance "will assess the risks posed by the top raw materials (such as mica, cobalt, rubber and leather) in the automotive sector," said Stefan Crets of the CSR Europe business network. "This will allow Drive Sustainability to identify the most impactful activities to pursue" to address issues within the supply chain.Reporting by Andreas Cremer.Related Video: Image Credit: Michael Robinson Chavez/The Washington Post via Getty Images Green BMW Ford Honda Jaguar Land Rover Mercedes-Benz Automakers Toyota Volkswagen Volvo Green Automakers Green Culture Electric Scania ethics mining
