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.

E.U. executive conditionally approves Daimler, BMW car-sharing deal

BRUSSELS — The European Union's competition authority said on Wednesday it had approved the plan of German luxury carmakers Daimler and BMW to combine their car-sharing businesses, subject to conditions. Under the deal, which includes car-sharing units Car2Go and DriveNow as well as ride-hailing, parking and charging services, Daimler and BMW will each hold 50 percent stakes in a joint venture. They have offered concessions to address E.U. antitrust concerns over the deal they hope would let them better compete with U.S. rival Uber and China's Didi Chuxing. The European Commission has found the deal would raise competition concerns for free-floating car sharing services in Berlin, Cologne, Duesseldorf, Hamburg, Munich and Vienna. It said Daimler and BMW agreed to a remedy package in the six cities. "The commitments thus fully address the Commission's concerns as they will reduce the barriers to entry for competing free-floating car sharing providers," the Commission said in a statement. "Therefore the Commission concluded that the proposed transaction, as modified by the commitments, would no longer raise competition concerns. The Commission's decision is conditional upon full compliance with the commitments." Reporting by Gabriela Baczynska and Philip Blenkinsop. Related Video:

Watch these Super Bowl car commercials [UPDATE]

On Sunday, February 3, the New England Patriots take on the Los Angeles Rams in Super Bowl 53 at Mercedes-Benz Stadium in Atlanta, Georgia. Some will watch because of the storyline of the old-school dynasty facing off against the new-school wunderkinds, but a large chunk of people will solely be watching for the commercials. Lucky for those who slot into the latter category, many of the manufacturers release their super bowl ads ahead of time, or have simply opted to release the commercials only online. Scroll down to see what car companies have already shown their cards. Audi Audi goes the comedic route in its clip for the Big Game. It starts with a grandpa showing his grandson a gorgeous Audi e-tron GT tucked away in a garage before he's shaken awake. Turns out he was just choking on a cashew in his cubicle at his boring job. Dodge Dodge does what it knows: create enough smoke to punch more holes in the ozone layer. Set to "The Devil Went Down to Georgia (the Super Bowl is in Atlanta, get it!?), a Challenger SRT Hellcat widebody, Charger SRT Hellcat, and Durango SRT are seen ripping through a city, leaving a trail of rubber crumbs in their wakes. Genesis Genesis has not yet released a commercial prior to the Super Bowl, but it is the official luxury vehicle of the NFL. Because of this, Genesis is hosting a fan experience for 10 days before the game. It will showcase the brand's cars, offer games, and have photos opportunities and autograph days. Hyundai Jason Bateman alert! Hyundai is one of the few companies to hook a major celebrity for its advertisement, and the casting is perfect. Bateman plays a doorman who takes people to various terrible events in life, including root canals, the middle seat, and shopping for a car. The ad centers around Hyundai's Shopper Assurance, which is Hyundai's new method for car shopping. Jeep An old 1963 Jeep Gladiator finds its strength in the crusher and transforms into a a new 2020 Gladiator, with a firm declaration that the nameplate is officially back. Kia Through Kia's commercial, a young boy wonders out loud what it'd be like if the millions spent on Super Bowl commercials were used to help others.
