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A documentary shows how Houston, Texas significantly improved its outdated bus system.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

Mercedes Sprinter updated to take on Ford Transit, Ram ProMaster

By the end of this year, the Mercedes-Benz Sprinter will be the second-oldest nameplate in its segment here in the States, but with hot new competition waiting in the wings, Mercedes-Benz is giving its hauler a freshened look and more equipment to stave off rivals. The Sprinter was a pioneer in bringing Euro-style delivery vans to North America, and it's inspired others to transplant their Continental offerings, with the all-new Ford Transit and Ram Promaster models launching shortly. It will also continue to do battle with lower-cost traditional competitors like the Chevrolet Express and Ford E-Series.
The big Sprinter will thus get a new look to go with more safety features and available technology. While the information released here technically covers the Euro-spec 2013 Sprinter (which goes on sale in September), the US market is expected to get the new Sprinter for the 2014 model year with many of the same features. Some of this new technology includes a Crosswind Assist feature as standard equipment and the availability of Collision Prevention Assist and Blind Spot Assist as optional safety measures - Mercedes-Benz says that all three are firsts for any van in the world. Also added to the updated Sprinter is a new 1.8-liter supercharged gasoline (or CNG) engine producing 156 horsepower, which will complement the line of diesel engines that carry over and help make the Sprinter the first cargo van to meet the upcoming Euro VI emissions standards. Additionally, a lower ride height is said to improve fuel economy and should improve handling while aiding ingress and egress for both people and cargo.
In terms of styling, the Sprinter's new face also looks more like the current line of Mercedes-Benz passenger cars. This includes a more upright grille along with changes to the hood, headlights and bumper that lend it a closer kinship to models like the CLS-Class and the updated E-Class. The Sprinter will offer both halogen and HID headlights, while the latter will get LED running lamps and offer Highbeam Assist. The images shown here only reveal the exterior from front angles, but it looks like few, if any, changes have been made to the rear of the van. Interior upgrades include a thicker steering wheel, a new shift lever and the latest in audio, navigation and entertainment systems.

Mercedes-Benz engines with 48-volt systems coming in 2017

As part of a big green push announced yesterday, Mercedes-Benz is jumping into the world of 48-volt power. The company will launch a new family of efficient gasoline engines next year and will begin rolling out 48-volt systems with it, likely in its more expensive cars first. Mercedes will use the 48-volt systems to power mild-hybrid functions like energy recuperation (commonly called brake regeneration), engine stop-start, electric boost, and even moving a car from a stop on electric power alone. These features will be enabled through either an integrated starter-generator (Mercedes abbreviates it ISG) or a belt-driven generator (RSG). (RSG is from the German word for belt-driven generator, Riemenstartergeneratoren. That's your language lesson for the day.) Mercedes didn't offer many other details on the new family of engines. There are 48-volt systems already in production; Audi's three-compressor SQ7 engine uses an electric supercharger run by a 48-volt system, and there's a new SQ5 diesel on the horizon that will use a similar setup with the medium-voltage system. Electric superchargers require a lot of juice, which can be fed by either a supercapacitor or batteries in a 48-volt system. Why 48-volt Matters: Current hybrid and battery-electric vehicles make use of very high voltages in their batteries, motors, and the wiring that connects them, usually around 200 to 600 volts. The high voltage gives them enough power to move a big vehicle, but it also creates safety issues. The way to mitigate those safety issues is with added equipment, and that increases both cost and weight. You can see where this is going. By switching to a 48-volt system, the high-voltage issues go away and the electrical architecture benefits from four times the voltage of a normal vehicle system and uses the same current, providing four times the power. The electrical architecture will cost more than a 12-volt system but less than the complex and more dangerous systems in current electrified vehicles. The added cost makes sense now because automakers are running out of ways to wisely spend money for efficiency gains. Cars can retain a cheaper 12-volt battery for lower-power accessories and run the high-draw systems on the 48-volt circuit. The industry is moving toward 48-volt power, with the SAE working on a standard for the systems and Delphi claiming a 10-percent increase in fuel economy for cars that make the switch.
