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.

Red Bull may seek engines from Ferrari after Mercedes snub

Red Bull and Renault's fractured relationship is pushing the Austrian F1 team to find a new engine provider. But after a trip across the German border to chat with Mercedes-Benz proved fruitless, the team is apparently set to head across its home country's southern border, and into Italy. Yep, Red Bull Ferrari could be a thing next season. According to RBR boss Christian Horner, the company is just doing "necessary due diligence" in contacting other engine suppliers, although he's willfully admitted to Germany's Bild newspaper that the "idea of Mercedes is finished," BBC Sport reports. It wasn't so much that Mercedes and Red Bull couldn't come to financial agreement – Red Bull owner Dietrich Mateschitz views throwing money into F1 in much the same way you or I toss pennies into the mall fountain – but rather that the Germans had no interest in supplying the best engines on the grid to the factory team's perennial rival. BBC Sport seems to think that fact, along with what the outlet calls Red Bull's "antagonistic" relationship with engine suppliers, killed the Mercedes deal. Honda and RBR aren't likely to happen either, thanks to McLaren (not that we think Red Bull would approach the Japanese, which have struggled mightily all season long). By process of elimination, that just leaves Ferrari. Scuderia Ferrari Team Principal Maurizio Arrivabene confirmed that his team can accommodate Red Bull's engine needs, and that he wasn't concerned with the idea of a Ferrari engine in an Adrian Newey-designed body. "In theory they have big names, with Newey as chief designer and it is easy to think that if you give them the engine they will build a scary chassis, which means they will be really competitive," Arrivabene told BBC Sport. "Concerning my team, my engineers and aerodynamicists know their own jobs. For that reason I don't have a problem, and competition is nice when you have a stronger competitor." "This doesn't mean tomorrow morning we will give our engines to Red Bull or Toro Rosso," Arrivabene added. And it's that statement we'd suggest remembering. There are, after all, still seven races left in the 2015 season, which is quite a lot of time for new and different developments within the sport's notoriously gruesome political process. In other words, don't count on an announcement from any team or manufacturer for at least a few more races. Related Video:

Major Alexa deal will bring Amazon services into more cars

Amazon and its personal assistance service Alexa are partnering with HERE Technologies to create a new connected mobility service powerhouse. Alexa will integrate with HERE's navigation and location services to offer what the two companies are calling a "true voice-first-navigation experience." Alexa will come pre-integrated with HERE navigation on-demand, which the automakers can then enable, which should help cut down on development time. One of the biggest features from this partnership is how directions could be offered and delivered using HERE's Open Location Platform (OLP). Currently, the OLP uses data from several car manufacturers to provide insights into real-time location and traffic. But on Alexa, this could be used to provide directional context. For example, Alexa could say, "Turn right after [such-and-such a building]" rather than just, "Turn right." Amazon has been testing the automotive waters throughout the past decade. Its home-based Alexa-enabled devices are already offered with connections to several manufacturers. To various degrees of integration, it can already pair with Ford, Genesis, Toyota, Lexus, Hyundai and BMW vehicles. At the end of 2018, Amazon took things a step further when it introduced the Echo Auto, a Bluetooth-connected Alexa assistant device that can be physically kept in a car. Currently only available by invitation (its production and distribution have been delayed), the $25 device is essentially a voice service that works together with smartphones and connects to a car's speakers. Users can command it to do a variety of things, including playing music, setting navigation, opening the garage door, finding local stores, making calls, setting reminders, and thousands of other "skills." According to The Verge, nearly 1 million people have already ordered the device. Some (well, probably few) may know HERE Technologies from its maps on Windows Phones. We all know how that turned out, though. Today, HERE has expanded into a multi-function suite that is available in multiple mediums, including many automotive applications. HERE Automotive's connected vehicle services include real-time traffic, parking, weather, fuel prices, hazard warnings, traffic sign integration, and even EV charging stations. These all incorporate and extend the use of HERE's location and tracking programming. HERE is already partnered with BMW, Audi, Daimler, Intel, Mobileye, NVIDIA, and has investments from Bosch, Continental and Pioneer.
