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A documentary shows how Houston, Texas significantly improved its outdated bus system.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

BMW 4 Series Convertible basks in the sun

The BMW 4 Series Convertible will show its non-camouflaged face sometime later this year, but our spies recently caught this nearly naked prototype out getting some sun. As you'll recall, the droptop 4 Series replaces the 3 Series Convertible in the BMW range, and if our recent stint behind the wheel of the new 435i Coupe is anything to go on, this topless 4er should be quite a fun runabout for sun-drenched motoring.
To no one's surprise, the 4 Series Convertible shares all of its design with the 4 Series coupe, save, of course, the obvious roofectomy. Beyond that, the topless 2+2 will use the same engines and transmissions as the coupe, meaning it should arrive in the US in both 428i and 435i guises, powered by a 2.0-liter turbocharged inline-four and 3.0-liter turbocharged inline-six, respectively. Both six-speed manual and eight-speed automatic transmissions will be available.
The car spied this time around has the full M Sport visual treatment, with the revised (and better-looking) front fascia, larger 19-inch wheels, and attractive Melbourne Red paint. Interestingly, it appears this prototype has the standard xenon headlamp setup, rather than the full-LED option that's also available.
