2014 Mercedes-Benz SLS AMG Black Series [w/video]

The biggest misconception about the Mercedes-Benz SLS AMG Black Series is that it's simply a higher-performing version of the SLS GT - a closer look, or better yet, a few hot laps on a high-speed racing circuit, reveals that is anything but the case.
Launched in the States in mid-2011, the standard SLS GT is a 583-horsepower, all-aluminum, gull-wing coupe with performance that positions it near the top of the exotic segment. While the AMG team at Mercedes-Benz could have left it alone, their experience with the SLS AMG GT3 race car said there was room for improvement, so they devised the SLS Black Series. The transformation from SLS GT to SLS Black Series is extensive, with no fewer than 17 different significant enhancements.
The engine mapping, crankshaft, connecting rods, valve-train, intake, exhaust and cooling are all modified and the engine's redline bumps up from 7,200 to 8,000 rpm, which pushes output of the hand-built 6.3-liter V8 to 622 horsepower. The power steering receives a new ratio, a coil-over AMG Adaptive Performance suspension is installed along with underbody braces, the track is widened, two-piece carbon-ceramic brakes replace iron rotors at each corner and a lightweight titanium exhaust is fitted beneath. The AMG Speedshift seven-speed dual-clutch gearbox is modified and an electronically controlled AMG rear differential lock ensures the power goes to the pavement. Last on the mechanical upgrades are new lightweight forged wheels (10x19 inches front and 12x20 inches rear) wrapped in special R-compound Michelin Pilot Sport Cup tires.

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A documentary shows how Houston, Texas significantly improved its outdated bus system.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

Mercedes GLE to debut in NY, will get plug-in variant

On the eve of the 2015 Detroit Auto Show, Dieter Zetsche, Chairman of Daimler AG, said that 2015 will be the "Year of the SUV" at Mercedes-Benz. This means a host of new and updated sport-utility and crossover models, kicked off with the debut of the GLE-Class Coupe (pictured above) – in 450 AMG Sport and Mercedes-AMG GLE63 variants – here in the Motor City. But there's far more in store throughout the year. First, Mercedes has confirmed it will debut the non-coupe GLE-Class – the M-Class replacement – at the New York Auto Show in April. It will share most of its architecture with the GLE Coupe revealed here in Detroit, but will also come with a plug-in hybrid option. Mercedes-Benz debuted an S-Class Plug-In Hybrid at the Los Angeles Auto Show last November, and will expand this technology to other core models in its range. First, we will see the C350 Plug-In Hybrid, which also makes its debut here in Detroit. Beyond that, Mercedes has confirmed that the GLE-Class will benefit from a plug-in option, as will the upcoming GLC-Class crossover – the renamed replacement for the GLK. No official timing has been given for the GLC, but Mercedes confirms that both it and its largest utility vehicle – the GLS-Class (currently known as the GL-Class) – will debut "later this year." Year of the SUV, indeed.
