Brabus 850 6.0 Biturbo Coupe is an extroverted, 217-mph Mercedes S63 AMG

The Mercedes-Benz S-Class is a prime example of handsome, restrained design. It's classy but not shouty, stylish without trying too hard. Of course, Brabus can address that um, problem, for you, without much issue. Meet the Brabus 850 6.0 Biturbo Coupe, an extensively modified version of the S63 AMG Coupe. Larger intakes and lots of carbon fiber typify the front end, while the tail sports a new diffuser and rear spoiler, both of which are finished in carbon fiber. Meanwhile, Brabus is offering a variety of wheel designs, ranging in size from 18 to 22 inches, and with the customer's choice of Continental, Pirelli and Yokohama rubber. The most questionable changes, though, happen in the cabin, where black Mastik leather is finished with copper stitching and piping. Brabus then takes 219 different interior trim pieces and lines them in Shadow Gold paint, just like the Monoblock wheels featured on the vehicle above. Of course, Brabus does much, much more than just offer its own take on the normally conservative Mercedes aesthetics. There's a bit of tweaking to the powertrain. Despite the "6.0" in its name, the donor S63 AMG's 5.5-liter, biturbocharged V8 has been enlarged to just over 5.9 liters (5,912 cc, to be precise), thanks to a larger cylinder bore and a longer stroke, the latter of which comes from a Brabus-spec crankshaft. While Brabus may be exaggerating about the size of its new coupe's engine, the tuning firm is not overstating said powerplant's output. A stout 850 horsepower is teamed with an electronically limited 848 pound-feet of torque. There's more to this modded Mercedes than that, though, as Brabus claims the 5.9-liter is actually capable of turning out a silly 1,069 lb-ft, but that it needed to be limited "in the interest of the longevity of the entire powertrain." All this extra oomph comes from a pair of "special" Brabus turbochargers, as well as new exhaust manifolds and a stainless steel exhaust system. A new intake module also helps breathing, while the engine's ECU has been updated for extra performance. Aside from a new set of paddle shifters, the S63 AMG's seven-speed gearbox was left unaltered, as was the 4Matic all-wheel-drive system. Oh, and if you live in Europe and really want to scare yourself, Brabus will offer the same engine treatment to the rear-drive S63 AMG that we don't get Stateside.

Mercedes-Benz, Volkswagen, and Audi announce Takata recalls

Daimler, Volkswagen, and Audi will recall nearly 1.7 million total vehicles in the US to replace their Takata airbag inflators. The Japanese parts supplier and the National Highway Traffic Safety Administration announced in late January that several automakers would need to fix around five million more vehicles, and the various companies have been releasing the details since then. Daimler has a recall for 841,000 vehicles in the US, including 705,000 from Mercedes-Benz and 136,000 from the company's van division. Reuters reports the affected models consist of 2005-2014 examples of the SLK-Class, C-Class, E-Class, M-Class, GL-Class, R-Class, and SLS-Class. The vans comprise the 2007-2014 models of the Dodge, Freightliner, and Mercedes Sprinter. Autoblog reached out to Mercedes USA to confirm these details, and we're awaiting a reply. Daimler expects the repair campaign to cost 340 million euros ($382 million at current rates). The company will book the costs as part of its financial year 2015 results, and net profit for that year will fall to 8.7 billion euros ($9.8 billion). Volkswagen's recall covers 680,000 vehicles in the US to replace their driver side airbags. The affected models have Takata's SDI and PSDI-5 inflators, which could rupture in an crash, but the automaker isn't aware of any explosions for these parts in its products. This campaign includes: 2006-2010 Passat Sedan and Wagon (German Production) 2012-2014 Eos 2010-2014 Golf 2010-2014 Jetta SportWagen 2012-2014 Passat (U.S. Production) 2009-2014 CC There are also 170,000 Audi vehicles with the SDI and PSDI-5 inflators in the US, but there are no reports of the parts rupturing in the company's models. The affected products are: 2005-2013 A3 2006-2009 A4 Cabrio 2009-2012 Q5 2010-2011 A5 Cabrio VW and Audi are still working to identify the specific VINs for these vehicles. Afterwards, they will notify affected owners. Ford, Mazda, and Honda already announced details for their new round of Takata repairs. VW and Audi also recalled a small number of Tiguans and Q5s to replace their side airbag inflators from the Japanese company. NHTSA still expects BMW and Saab to detail expanded safety campaigns.

Mercedes-Benz engines with 48-volt systems coming in 2017

As part of a big green push announced yesterday, Mercedes-Benz is jumping into the world of 48-volt power. The company will launch a new family of efficient gasoline engines next year and will begin rolling out 48-volt systems with it, likely in its more expensive cars first. Mercedes will use the 48-volt systems to power mild-hybrid functions like energy recuperation (commonly called brake regeneration), engine stop-start, electric boost, and even moving a car from a stop on electric power alone. These features will be enabled through either an integrated starter-generator (Mercedes abbreviates it ISG) or a belt-driven generator (RSG). (RSG is from the German word for belt-driven generator, Riemenstartergeneratoren. That's your language lesson for the day.) Mercedes didn't offer many other details on the new family of engines. There are 48-volt systems already in production; Audi's three-compressor SQ7 engine uses an electric supercharger run by a 48-volt system, and there's a new SQ5 diesel on the horizon that will use a similar setup with the medium-voltage system. Electric superchargers require a lot of juice, which can be fed by either a supercapacitor or batteries in a 48-volt system. Why 48-volt Matters: Current hybrid and battery-electric vehicles make use of very high voltages in their batteries, motors, and the wiring that connects them, usually around 200 to 600 volts. The high voltage gives them enough power to move a big vehicle, but it also creates safety issues. The way to mitigate those safety issues is with added equipment, and that increases both cost and weight. You can see where this is going. By switching to a 48-volt system, the high-voltage issues go away and the electrical architecture benefits from four times the voltage of a normal vehicle system and uses the same current, providing four times the power. The electrical architecture will cost more than a 12-volt system but less than the complex and more dangerous systems in current electrified vehicles. The added cost makes sense now because automakers are running out of ways to wisely spend money for efficiency gains. Cars can retain a cheaper 12-volt battery for lower-power accessories and run the high-draw systems on the 48-volt circuit. The industry is moving toward 48-volt power, with the SAE working on a standard for the systems and Delphi claiming a 10-percent increase in fuel economy for cars that make the switch.
