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A documentary shows how Houston, Texas significantly improved its outdated bus system.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

Project Maybach is an absurd, awesome off-road electric coupe

Mercedes has created some mighty unusual concepts for the Maybach luxury brand. The Exelero high-speed test car and the Ultimate Luxury SUV sedan come to mind. But the Project Maybach, designed in collaboration with late fashion designer Virgil Abloh, may be the wildest yet, being an electric off-road coupe. It's not just the fact it's a two-door off-road coupe. It's the fact that it's a nearly 20-foot-long two-door off-road coupe. And it has very traditional proportions and lines, with a gargantuan front end, and a somewhat less gargantuan rear end. It's squared-off, but in a more elegant, midcentury luxury car way than say, a Hummer. And of course, it has a huge chrome grille and highly embellished taillights, complete with Maybach logos. And yet, this old-school coupe sits high off the ground. It rolls on small, steel-style wheels with chunky tires. It even has skid plates, bolt-on fender flares, rock rails and a roll cage with a roof basket. It's all painted in a matte tan paint that makes it look like a desert-ready expedition vehicle. It's even arguably practical for expedition work. The somewhat spartan-looking interior has tan leather seats that recline fully flat for sleeping. Being an electric car with long areas unoccupied by people, plus that roof basket, it likely has loads of cargo space. On the hood are solar panels that might provide a bit of range, but would at least be handy for recouping some power for accessories. The interior seems to have additional storage bins and tools stowed in special compartments around the cabin. As for the actual performance and range, well, Mercedes has nothing specific. That's not entirely surprising, since this seems to be solely a design exercise. As such, don't expect to see a production model anytime soon. Then again, off-road luxury vehicles are certainly popular. Maybe Mercedes would consider it if there were enough seriously wealthy customers expressing interest. Related video:

2016 Mercedes-Benz C450 AMG Sport is not too hot, not too cold

Mercedes-Benz is moving to a new system for performance models, launching its AMG Sport line that will slot above the standard cars, but below the full-fledged Mercedes-AMG offerings. The perfect example of how this all looks can be seen with the C-Class – we've already driven (and enjoyed) the standard C300 and C400 offerings, and we're absolutely geeked to test the Mercedes-AMG C63. Slotting in the middle, though, is this new C450 AMG Sport, which makes its debut at the Detroit Auto Show this week. Power comes from the twin-turbocharged 3.0-liter V6 found in the C400, but output is increased to 362 horsepower and 384 pound-feet of torque – up from 329 and 354, respectively. That's all shuffled through the company's 7G-Tronic seven-speed automatic transmission, and sent to the road via 4Matic all-wheel drive. Hitting 60 miles per hour is said to take just 4.9 seconds, en route to a 155-mph top end. There's an AMG adaptive sport suspension with adjustable dampers (from the C63), and the interior and exterior aesthetics have been pumped up for a more sporting appearance. It all seems like a good fit, and we think it'll slot nicely in the middle of the already good C-Class range. Check out our fresh batch of lives images of the C450 above.
