Recharge Wrap-up: Houston's bus revival, autonomous trucks on the Autobahn

A documentary shows how Houston, Texas significantly improved its outdated bus system. Called High Frequency: Why Houston is Back on the Bus, the short film describes how the city reimagined its bus system to become more efficient, more useful and more popular. Despite some opposition, the change has proven to be effective, with bus ridership up eight percent in three months, and light rail ridership up due to complementary bus routes. See the video above, and read more at CityLab. Automakers sent autonomous semi trucks on the German Autobahn as part of the European Truck Platooning Challenge of 2016. Mercedes-Benz, Volvo and Scania, among other groups, sent platoons of trucks between Stuttgart, Germany, and Rotterdam, Holland. In Mercedes's platoon of three trucks, the lead truck was fitted with lasers and other sensors to guide the convoy down the road. The two following trucks relied on vehicle-to-vehicle communication to trail 50 feet behind the lead, making room for cars to come between them and closing the gaps when able. The close following distance provides fuel economy gains of up to 10 percent in the rearward trucks on account of the reduction in drag. Read more at Hybrid Cars. Renault has reduced NOx emissions in its Euro 6b diesel vehicles in real world driving conditions. By improving its exhaust gas recirculation systems and NOx traps, nitrogen oxide emissions are cut in half on average, under certain driving conditions. The improvements will be included in vehicles leaving the factory beginning in July of 2016. Beginning in October, owners of Renault Euro 6b diesels can have the modifications added to their cars for free. Read more from Renault. Tata Technologies is creating an innovation lab in California to partner with EV technology companies. Having a tech center in California allows Tata to work on technologies that will largely be deployed in the company's main market of Asia. "Today, we are partnering with companies and startups who have aspirations to sell in China, but a lot of what they do is in California," says Samir Yajnik of Tata Technologies.

Why all of this year's F1 noses are so ugly [w/video]

If you're a serious fan of Formula One, you already know all about The Great Nosecone Conundrum of 2014. Those given to parsing each year's F1 regulations predicted the strong possibility of the so-called "anteater" noses as far back as early December 2013. Highly suggestive visual evidence first came after Caterham's crash test in early January, with further proof coming as soon as Williams showed a rendering of the FW36 challenger for this year's championship. That car earned a name that wasn't nearly so kind as "anteater."
Casual followers of the sport - or anyone who gets the feed from this site - probably don't know what's happening, except to wonder why the current year's F1 cars are led by appendages that would make Cyrano de Bergerac feel a whole lot better about himself.
The short answer to the question of ugsome F1 noses is "FIA regulations and safety." The reason there are various kinds of ugsome noses is simpler: engineers. The same boffins who have given us advances including carbon fiber monocoques, six-wheeled cars, double diffusers and Drag Reduction Systems are bred to do everything in their power to exploit every possible freedom in the regulations to make the cars they're building go faster - the caveat being that those advances have to work within the overall philosophy of the whole car.

2015 Mercedes C-Class owners reporting bleeding seats [UPDATE]

UPDATE: Daimler AG became aware that, in a small number of individual cases, it is possible for temporary spots and/or shiny patches to form on the man-made leather surfaces of the 2015 C-Class in sub-freezing temperatures. No accidents or injuries have been reported, and we have no reason to believe that there are any hazards to customers. Replacement parts are expected to start shipping to dealers by next week. Owners of the 2015 Mercedes-Benz C-Class are learning the hard way that you don't necessarily want to buy a new vehicle in its first model year. Besides reports of poorly fitting taillights and faulty infotainment touchpads, a number of reports are popping up on the forums of MBWorld.org claiming that the compact luxury sedan's seats are, for lack of a better term, bleeding. Owners of US-built, 2015 C-Classes fitted with MB Tex vinyl interiors are reporting a white, oily, shiny residue discoloring their seats that shows up, often after cold cars are quickly heated. It's important to note that this residue is not necessarily staining the seats permanently – warm, soapy water is often all that's needed to restore the original finish. In other cases, the residue disappears of its own accord, only to reappear in an entirely different pattern. That doesn't make things any more acceptable to owners, many of whom have reached out to Mercedes with complaints. It's not clear how many vehicles are affected, but there are a sizable number of forum threads on the issue on MBWorld alone, and the problem is prevalent enough that Mercedes has issued a technical service bulletin to its dealers. According to the forum postings, the TSB instructs service technicians to replace the headrest and seat cover (except for the front, passenger-side seat bottom because of "factory calibration issues") in affected customer vehicles. New C-Class models in dealer inventories, meanwhile, are to get the soapy water treatment if they're showing signs of the residue. Neither one of those moves seems to represent a long-term fix, though. Black MB Tex seats – both the standard and sport variety – seem to be particularly susceptible to the residue, although we stumbled across at least one image of what looks like Silk Beige MB Tex with speckles of residue.
