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A documentary shows how Houston, Texas significantly improved its outdated bus system.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

Test drive the Mercedes SLS AMG Electric Drive with Chris Harris

It's hard to not like the Mercedes-Benz SLS AMG GT. The all-aluminum coupe is fitted with a wonderful naturally aspirated 6.2-liter V8 delivering 583 horsepower and 479 pound-feet of torque. Not only does the burly combustion engine launch the two-seater to 60 miles per hour in less than four seconds, but it does so with one of the world's greatest exhaust soundtracks as it roars, burbles and cackles down the road.
But what happens when Mercedes-Benz takes away the V8 and its accompanying fire-burning song? Stripped of one of its most appealing assets, does the SLS lose its soul?
Chris Harris recently had the opportunity to take the Mercedes-Benz SLS AMG Electric Drive for a track spin in Europe. Sans gasoline, but with four electric motors providing a combined 740 horsepower (737 pound-feet of torque), all-electric all-wheel drive coupe uses sophisticated torque vectoring and a multi-mode operating system to put oversteer - drifting! - back into the equation. Fun? You bet. See for yourself, below.

2015 Belgian Grand Prix is a return to scheduled programming

With summer intermission over, the second half of the Formula One season commenced in the Belgian countryside at Spa-Francorchamps. After qualifying, it looked a lot like the first half of the season with just a few minor changes. Lewis Hamilton was even more dominant in his Mercedes-AMG Petronas than usual, regularly taking half a second out of his teammate in just the middle sector of the circuit. Teammate Nico Rosberg tightened it up a tad for his final hot lap, but Hamilton still took pole by 0.45 seconds ahead of Rosberg in second. With his Williams back at a power track, Valtteri Bottas got himself up to third, although more than a second behind Hamilton. Romain Grosjean in the Lotus in fourth had his best qualifying performance since his fourth-place grid spot at the 2013 US Grand Prix. This was a huge boon for Lotus, the team facing another financial issue off track that threatened to have its cars impounded as soon as they left the circuit. Grosjean had to have his gearbox changed before the conclusion of six races, however, so the five-spot penalty meant he'd actually line up ninth for the race. Sergio Perez put the Sahara Force India in fifth, where we're more used to seeing his teammate Nico Hulkenberg, just ahead of Daniel Ricciardo in the Infiniti Red Bull Racing in sixth. Felipe Massa got the second Williams in seventh, in front of the second Lotus of Pastor Maldonado in eighth. Then came the first and only Ferrari in the top ten, Sebastian Vettel qualifying ninth after a disappointing Saturday for the scuderia; teammate Kimi Raikkonen suffered gearbox issues and qualified way down in 16th. Carlos Sainz took tenth in the Toro Rosso. A new start procedure in Belgium meant drivers had to handle clutches on their own, without the engineers finely tuning bite points between the garage and the start line. That was in conjunction with another rule limiting the kinds of radio messages possible between engineers and drivers, aiming to put more of the car in the drivers' hands. After an aborted start when Hulkenberg's car quit while sitting on the grid, Hamilton made the most of the new procedure. His start wasn't amazing but he beat everyone else off the line, while those behind were alternately getting bogged down or leaping ahead. Midway through the first lap the top ten was Hamilton, Perez, Ricciardo, Bottas, Rosberg, Vettel, Maldonado, Grosjean, Massa, Marcus Ericsson. At the end of 43 laps, Hamilton would still be in the lead.
