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A documentary shows how Houston, Texas significantly improved its outdated bus system.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

Fastest cars in the world by top speed, 0-60 and quarter mile

A claim for the title of “Fastest Car in the World” might seem easy to settle. ItÂ’s actually anything but: Are we talking production cars, race cars or customized monsters? And what does “fastest” even mean? For years, car publications have tended to define “fastest” in terms of an unbeatable top speed. ThatÂ’s distinct from the “quickest” car in a Usain Bolt-style dash from the starting blocks, as with the familiar 0-60 mph metric. Professionals often focus on track lap times or elapsed time-to-distance, as with a drag racer thatÂ’s first to trip the beam of light at the end of a quarter-mile; or the 1,000-foot trip of nitromethane-powered NHRA Top Fuel and Funny Car dragsters. Something tells us, however, that you're not seeking out an answer of "Brittany Force rewriting the NHRA record books with a 3.659-second pass at a boggling 338.17 mph." For most barroom speed arguments, the focus is firmly on cars you can buy in showrooms, even if many are beyond the financial means of all but the wealthiest buyers and collectors. Here are some of the enduring sources of speed claims, counter-claims, tall tales and taunting dismissals that are the lifeblood of car enthusiasts – now with EVs adding an unexpected twist to these passionate pursuits.   Fastest from the blocks: 0-60 mph Thirty years ago, any car that could clock 60 mph in five seconds or less was considered extremely quick. Today, high-performance, gasoline-powered sedans and SUVs are routinely breaking below 4 seconds. As of today, the 2023 Dodge Challenger SRT Demon 170 crushes all with a 0-60 mph time of just 1.66 seconds. That's simply absurd, but keep in mind the Demon was engineered with the single-minded purpose of going fast in a straight line. It's also important to realize that direct comparisons are difficult, because not all of these times were accomplished with similar conditions (prepped surfaces, adjustments for elevation and so on). The moral here is to take these times with a tiny grain of salt. After the Dodge, the Rimac Nevera comes in with an officially recorded 0-60 mph time of just 1.74 seconds. EVs crowd the quickest list, with the Pininfarina Battista coming in a few hundredths slower (1.79 seconds) than the Nevera and the Lucid Air sapphire (1.89 seconds) right after that. Eventually, you arrive to the Tesla Model S Plaid, which has a claimed 1.99-second 0-60 mph time, though instrumented testing by Car and Driver shows it accomplishes the deed in 2.1 seconds.

2015 Bahrain F1 Grand Prix puts a dark horse in the desert [spoilers]

Ferrari's Kimi Raikkonen had said after Malaysia that Ferrari can challenge Mercedes-AMG Petronas purely on pace, beyond the scope of tire wear, in the dry. We didn't see that in China, where Lewis Hamilton easily kept everyone behind and Ferrari's Sebastian Vettel only got close to Mercedes' Nico Rosberg when Rosberg slowed down to conserve his tires. But the Iceman's words seemed prescient during qualifying for the Bahrain Formula One Grand Prix. At the front, nothing has changed so far this year: four races, four pole positions for Lewis Hamilton. Instead of teammate Rosberg next to him, though, he'll look over to see the scarlet Ferrari of Vettel, who took advantage of Rosberg's cautiousness to snatch second place on the grid. In Q2, Rosberg tried to conserve the tires he'd start the race on and said he couldn't get into a groove in Q3, putting in a time 0.147 seconds slower than Vettel. The second Silver Arrows will share his row with the second Ferrari, Raikkonen – yet again – saying he might have left some time on the table during his hot lap but getting around just one tenth off Rosberg's time. Williams is established as the best of the rest behind two teams this year instead of just one last year, Valtteri Bottas claiming fifth ahead of Felipe Massa. Daniel Ricciardo of Infiniti Red Bull Racing said he wants to fight with the Williams', he'll be helped with a good start off the line for the first time this year. Nico Hulkenberg got Force India into Q3 for the first time since the Italian Grand Prix last year and into eighth on the grid, ahead of Carlos Sainz in the Toro Rosso and Romain Grosjean putting in another excellent day's work for Lotus. Come race time, it turned into Mercedes power against Ferrari strategy. When Sky F1 commentator Martin Brundle talks about the Mercedes-AMG Petronas team he often mentions how their engine advantage leads to other advantages throughout the car. Not having to use aerodynamic changes to make up for power unit deficiencies, for instance, means they can run the aero setup they want, which optimizes speed and tire wear throughout a lap. It equates to advantage on top of advantage on top of advantage. That's where Lewis Hamilton is right now, so fundamentally dialed in to his car and his racing that he run the races he wants to run. From the front spot, the Brit ripped off another perfect start and led the field into Turn 1, relinquishing the lead only during pit stops.
