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A documentary shows how Houston, Texas significantly improved its outdated bus system.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.

Race recap: 2016 Hungarian Grand Prix was the pits

The Hungarian Grand Prix hasn't seen a race this calculated since 2012, when Lewis Hamilton – driving for McLaren – led from pole position to the checkered flag. We don't expect massive action from the Hungaroring, but Hamilton's first win for Mercedes in 2013, the thrilling wet mess in 2014, and Ferrari's surprising dominance in 2015 made us hope for more on-track commotion this year. Hungary denied us that. Hamilton parked his Mercedes-AMG Petronas in second on the grid but stole the lead through Turn 1 and never looked back. Teammate Nico Rosberg yo-yoed behind him in second place, getting into DRS range on a few occasions but never close enough to pass. Red Bull's Daniel Ricciardo kept the leading duo honest, but the Aussie couldn't put genuine fear into the German team and finished third. This is the third year in a row for Ricciardo on the Hungary podium. The pits provided our few scraps of excitement. During a stretch when Ricciardo managed to close on Rosberg, Mercedes told Hamilton to speed up. When Hamilton said he couldn't go faster, Mercedes said they'd pit second-place Rosberg first instead. Suddenly, Hamilton found the extra pace. Ricciardo pitted in early, hoping that fresh tires and fast laps could allow him to pass one or both Mercedes drivers when they pitted, but once Hamilton hit the throttle the Red Bull couldn't respond. Further down the lineup, Jenson Button came in on Lap 5 so McLaren could fix his brake pedal problem. The radio exchange before the stop included one forbidden instruction to Button, though, so the Englishman had to return to the pits for a drive-through penalty. Renault's Jolyon Palmer beat Force India's Nico Hulkenberg in a straight-up pit stop battle on Lap 40, but threw the good work away on Lap 49 with a spin on track that cost him three places. A pit wall miscommunication meant the Force India pit crew wasn't ready for Sergio Perez when the Mexican arrived for his second stop on Lap 43. And Daniel Kvyat's regrettable run at Toro Rosso continued, first with car issues, then a drive-through penalty for speeding in the pit lane. Sebastian Vettel brought his Ferrari home fourth, sniffing Ricciardo's gearbox at the flag but unable to get around the Red Bull. Max Verstappen enacted a replay of the final stages of the Spanish Grand Prix, finishing fifth by holding Ferrari's Kimi Raikkonen behind for 19 laps.

Mercedes forced to lower MPG ratings on two C300 models *UPDATE

*UPDATE: Donna Boland, manager of corporate communications at Mercedes Benz USA, told AutoblogGreen that the sticker change only applied to around 500 C-Class vehicles on dealer lots, since a new C-Class came out in late August. "About 500 are left in the United States, and we've relabeled them," she said. First Hyundai, then Ford and now Mercedes-Benz. The list of companies that have had to change their vehicles' official EPA fuel economy ratings has just grown by one with the announcement that the 2013 and 2014 C300 4-Matic FFV and PZEV versions need to have their EPA labels adjusted. The changes aren't massive, at most one mile per gallon. The changes aren't massive, at most one mile per gallon, but they are lower than before. The FFV version goes from 20 to 19 mpg in the city while the PZEV drops one mpg across the board from 23/20/29 combined/city/highway) to 22/19/28. The FFV's combined (22) and highway (27) ratings stay the same. Other Mercedes vehicles that were spot checked turned out to have accurate labels. The problem, which is reminiscent of the issues that Ford had with the Total Road Load Horsepower, was that "Mercedes underestimated the impact of aerodynamic drag and tire rolling resistance known as 'road-load,'" the EPA said in a statement you can read below. We have asked Mercedes for more information on the issue but have not yet heard back. We're not sure how many vehicles the EPA is retesting (or asking to be retested), but the agency says that the C300 models were evaluated again by Mercedes "with EPA oversight" and the EPA did its own tests at the National Vehicle and Fuel Emissions Laboratory in Ann Arbor, MI. Christopher Grundler, the director of EPA's Office of Transportation and Air Quality, said that the EPA knows that the changes are minimal, but that, "it is important that our oversight system is producing the correct results because even one MPG matters to consumers." In case you need a primer in the recent history of companies adjusting their EPA numbers, check out this and this. Based on today's news, we won't be surprised to hear more changes are coming. EPA Requires Mercedes-Benz to Correct Fuel Economy Labels for Two C300 4-Matic Vehicles WASHINGTON - The U.S. Environmental Protection Agency (EPA) is revising estimates for two 2013/2014 Mercedes C300 4-matic vehicles, the FFV and PZEV, to ensure consumers are given accurate fuel economy values.
