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.

BMW negotiates Daimler alliance, buys out car-service partner Sixt

Sixt sells its stake in DriveNow car-sharing to BMW BMW in talks with Daimler to combine car-sharing Combining car-sharing business to aid robotaxi plans FRANKFURT — Germany's BMW has bought out partner Sixt from their joint venture DriveNow, paving the way for a broader car-sharing and driverless taxi alliance with Daimler to compete against Uber and Lyft. Car rental company Sixt said on Monday it would generate an extraordinary pre-tax profit of about 200 million euros ($248 million) in 2018 from the sale of the DriveNow stake to BMW for 209 million euros. "With DriveNow as a wholly-owned subsidiary, we have all options for continued strategic development of our services," said Peter Schwarzenbauer, BMW's board member for Digital Business Innovation. "Our experience with mobility services supports our development of future autonomous, electrified and connected fleets," he said, adding that BMW aims to have 100 million customers for "premium mobility services" by 2025. The Sixt deal comes as BMW moves closer to a deal to combine its car-sharing services with Daimler's Car2Go, a person familiar with the discussions told Reuters last week. The German carmakers want to build a joint business that includes car sharing, ride-hailing, electric vehicle charging, and digital parking services, a senior executive at one of the companies said on Monday. Mercedes-Benz parent Daimler and BMW declined comment on the status of potential talks on their car-sharing business. "This is speculation, we do not comment," BMW said. The senior executive, who declined to be named because the plan is not public, said: "This will create an ecosystem which can also be used for managing robotaxi (driverless taxi) fleets." BMW would contribute its ParkNow and ChargeNow businesses to the common company, the executive said, adding that there were still differences of opinion over the valuation of Car2Go. The market for ride-hailing services currently makes up around 33 percent of the global taxi market, and could grow eightfold to $285 billion by 2030, once autonomous robotaxis are in operation, Goldman Sachs said in a recent research note. BMW and Daimler are now working on developing autonomous cars, vehicles which could enable them to up-end the market for taxi and ride-hailing services.

Daimler exec hypothetically discusses 3-cylinder engines for small hybrids

Is three the magic number of cylinders for Mercedes-Benz parent Daimler and its efforts to build smaller powertrains for its compact hybrids? Potentially, yes, the German automaker could see the need for three-cylinder mills, Automotive News reports. The company doesn't have any plans for them as of yet, though. Daimler executive Bernhard Heil talked with Automotive News about the challenges of using four-cylinder engines in a front-wheel-drive setup and said that three-cylinder engines could work in transverse-mounted powertrains for hybrid cars. For now, though, the company doesn't actually have any plans to go in that direction, Mercedes-Benz spokesman Christoph Horn said in an e-mail to AutoblogGreen. Horn wrote that Heil "actually said that if ever MB would use a three-cylinder engine than [it would be] in a configuration where space is restricted, such as when using a hybrid power train in a compact car." Of course, the only compact "hybrid" that Mercedes-Benz has is the 2015 C-Class, but that refers to the "hybrid" body is made of 48-percent aluminum, up from the current nine percent, as well as steel. It has nothing to do with the powertrain. Beyond that, there's always the Mercedes-Benz S500 Plug-in Hybrid that the company unveiled at the Frankfurt Motor Show last fall, but that model, which will debut in Europe later this year and arrive stateside next year, has a 3.0-liter turbocharged V6 and an 80-kilowatt electric motor that propels the plug-in from 0 to 62 miles per hour in 5.5 seconds. Not exactly three-cylinder territory, that.
