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A documentary shows how Houston, Texas significantly improved its outdated bus system.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

RideCell provides technology for services such as carsharing, ridesharing and other transit services. "The convergence of transportation trends in cities is of key importance to BMW," says Ulrich Quay, head of BMW i Ventures.

2017 BMW Alpina B7 xDrive is an M7 by any other name

Have you been waiting for BMW to release a more potent version of the new 7 Series? Try 600 horsepower on for size and forget all about the famous M badge. The new flagship performance sedan from Munich is the 2017 BMW Alpina B7 xDrive. Alpina is Bimmer's tuner of choice, and it designs customized features to integrate precisely with the factory build. The B7's 4.4-liter twin-turbocharged V8 is massaged to deliver a nice, round 600 horsepower, and a torque figure nearly as impressive at 590 pound-feet available from just 3,000 rpm. All that muscle is channeled through an eight-speed automatic to all four wheels (as you might have guessed from the new xDrive handle). The result is an Autobahn-blitzing 0-60 time quoted at just 3.6 seconds – 0.8 seconds quicker than its predecessor – and a top speed estimated at 193 miles per hour. Those would have been considered supercar figures not that long ago, but are delivered here in a luxury sedan as big as they come. They also stand up pretty well to the forced-induction eight-cylinder competition in the Audi S8 Plus, Jaguar XJR, Maserati Quattroporte GTS, and Mercedes-AMG S63. The Audi produces a bit more power but less torque, the Mercedes does the opposite, and the Jaguar and Maserati are left in the dust. Only the S8 Plus dares claim a quicker 0-60 time, and even then it's only said to be a tenth quicker. (The Mercedes-AMG S65 boasts much higher output from its V12, but without an all-wheel drive system capable of handling all its muscle, it's a fair bit slower off the line.) Keeping all that momentum under control is an air suspension with adaptive dampers, active roll bars, and four-wheel steering. It's all mounted to 20-inch wheels wearing Michelin Pilot Super Sport rubber and packing oversized brakes measuring 15.5 inches at the front (with four-piston fixed calipers) and 14.5 inches (with floating calipers) at the back. Of course it also benefits from all the advancements that the Bavarian automaker developed for the latest 7 Series, but takes things a step further with a specific aero kit and an interior decked out in even more upscale leather and trim. The finished product may not wear an M7 badge as so many have called for from BMW's flagship sedan series over the years. But the Alpina name carries a cachet all its own and has for the past 50 years now – which is a few years longer than BMW M GmbH has been around.

Recharge Wrap-up: GKN electric AWD, $8,500 for Tesla brake repair

A Tesla owner in Canada was quoted $8,500 to repair the brakes in his 2012 Model S. Tesla waived the labor costs, bringing the total price down to $5,824.75. Tesla said that since regenerative braking means the regular brakes get less use, occasional hard braking can help keep them working properly. Also, the salt on the roads in winter leads to corrosion of both the rotors and the calipers. Tesla suggests yearly brake service in harsh climates. Read more at Clean Technica. GKN is launching an electric all-wheel-drive system using its eAxle technology. BMW will be the first to use the system – which is optimized for compact vehicle platforms – in its 2 Series Active Tourer plug-in hybrid. On its own, the electric axle drive offers up to 70 kilowatts (94 horsepower) and 1,475 pound-feet of torque, enough to propel a vehicle up to almost 78 miles per hour under electric power alone. It can also disengage from the driveline when it's not needed in order to reduce rotating losses at higher speeds. Read more from Green Car Congress. The Orange County Transit Authority's (OCTA) first zero-emission, hydrogen powered bus uses a fuel cell from Ballard. The 40-foot ElDorado National Axess bus, powered by Ballard's FCveloCity fuel cell, was funded by the Federal Transit Administration's National Fuel Cell Bus Program. "Clean energy mass transit alternatives, such as this new fuel cell bus in Orange County, are a tremendous example of what can be done to help address clean air challenges," says Ballard Vice President Karim Kassam. "We are excited by the progress being made at OCTA and by others in California." Read more in the press release below. Ballard Module Powers First Zero-Emission Fuel Cell Bus for Orange County Transportation Authority VANCOUVER, CANADA and ORANGE COUNTY, USA – On May 23rd representatives from Ballard attended a ceremony to unveil the first zero-emission fuel cell bus to provide service for the Orange County Transportation Authority (OCTA), one of the largest transit agencies in California. The OCTA bus is the 6th American Fuel Cell Bus (AFCB) configuration delivered in California. Karim Kassam, Ballard Vice President - Commercial said, "Clean energy mass transit alternatives, such as this new fuel cell bus in Orange County, are a tremendous example of what can be done to help address clean air challenges.
