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.

Mercedes to roll out C63 AMG late in 2014 with 4.0L V8

The new 2014 Mercedes-Benz C-Class is upon us, launching initially in North America with turbocharged four-cylinder C300 4Matic and six-cylinder C400 4Matic flavors. But that's only the tip of the proverbial iceberg when it comes to the vast array of powertrain configurations that will be offered in the new C-Class in markets around the world. Orders will soon be rolling in for gasoline, hybrid and diesel engines with four, six or eight cylinders, driving the rear wheels or all four, with the seven-speed automatic transmission soon to be replaced by a new nine-speed unit. But what enthusiasts are really looking forward to is the next C63 AMG.
As BMW has done with the M3 (and new M4), Mercedes has gradually ratcheted up the cylinder count in its AMG C-Class, graduating from the 3.6-liter V6 in the original C36 AMG to the 4.3-liter V8 in the C43 AMG, then the 5.5-liter V8 in the C55 AMG before going the distance with the sublime 6.2-liter V8 in the C63 AMG. Like its rivals, Mercedes is expected to use turbochargers as a replacement for displacement in the next model, but unlike its Bavarian rival, it won't be losing any cylinders in the process.
Skipping the 5.5-liter twin-turbo V8 that has gone on to power other AMG models, the next C63 AMG is still expected to introduce a new 4.0-liter twin-turbo V8 producing between 450 and 500 horsepower. It'll also reportedly keep the same seven-speed automatic transmission (instead of switching to the new nine-speed), but the jury's still out on whether it'll come with rear- or all-wheel drive (or offer buyers the choice). The downsized V8 - codenamed M177 - is then expected to find its way into other models, but the C-Class will be the first to get it when it arrives before the end of the new year ahead.

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.
