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.

2016 Mercedes CLA and GLA get more power, quicker

Unlike in Europe, Mercedes-Benz doesn't have hyper hatches like the Audi RS3 to compete against in North America, at least not yet. However, the company isn't letting its high-performance compacts get behind the times anywhere in the world with the announcement that the CLA45 AMG and GLA45 AMG in the US are getting practically the same raft of upgrades as the ones across the pond. Both models go on sale in October in US dealers. Like its European counterpart, the 2.0-liter turbocharged four-cylinder in the diminutive AMGs receives upgrades to produce 375 horsepower and 350 pound-feet of torque (the 381 hp rating over there is in metric ponies). That's an impressive 20-horsepower and 18 lb-ft bump over the current version of the mill. Beyond just the boost in output, quicker acceleration comes from revised, more aggressive ratios in third through seventh gears. The latest AMGs make great use of their upgrades, too. The 2016 GLA45 now clocks the run to 60 miles per hour in 4.3 seconds, a staggering half-second quicker than the 2015 model. The CLA45 slices 0.3 seconds off its time to make the sprint in 4.1 seconds, which gives the sedan the same acceleration as a SL63 AMG. In addition to the powertrain tweaks, the 2016 models get a few other added luxuries. As in Europe, they receive the Dynamic Select System that uses a rotary knob select from multiple driving modes. Inside, there's standard keyless start, dual-zone climate controls, and Mercedes' latest infotainment unit. A "Turbo 4Matic" badge on the fender now hints at the vehicles' performance potential. The new Dynamic Plus Package is the major addition to the options list. It combines a limited slip differential at the front, AMG Adaptive Suspension, Race Mode, Performance Steering Wheel, and pushes the top speed to 167 mph. At the same time, the AMG Driver's Package is discontinued, and the AMG Performance Studio Package is dropped on the CLA45. Related Video:

Mercedes-Benz Concept GLC Coupe comes to China ready to fight BMW's X4

There's little denying that small crossovers are hot right now. Not only are automakers scrambling to exploit the popularity of the market, they're doing so by offering unique twists on the traditional two-box body style – enter the coupe-like four-door CUV. BMW, for example, has the X4, and now, Mercedes-Benz is bringing a challenger of its own. While it wears the concept name, the new GLC Coupe clearly foreshadows a production model that'll duke it out with the aforementioned BMW. If the vehicle shown above is any indication, when that fight happens, Mercedes will enter it with design on its side. The sheetmetal is muscular, with strong lines on the profile and the hood, while major themes in the front, back and sides are reminiscent of higher-end Silver Arrows. While we doubt the production GLC Coupe will be much of a trail bomber, fore and aft scuff plating is there to give the impression it can handle itself off road. Also, we feel obligated to give Mercedes bonus design points for the diagonally stacked quad exhausts at the back. It's worth noting that the Concept GLC Coupe's styling previews not one but two production vehicles, as it's logical to assume the design language featured here will have a strong influence on the next GLC (the crossover formerly known as the GLK). Not only will the GLC Coupe have aesthetics on its side, at 15.5-feet long and riding on a 111.4-inch wheelbase, it's larger than its rival from Munich, too, although only just. The X4 is two inches shorter overall and has an extra 0.8 inches between the axles. The Benz is wider, too, at 78.7 inches, compared to 74.1. Lending credence to the Concept GLC Coupe's production status, Mercedes released a pretty substantial array of technical details on its new four-door, coupe-crossover. With a twin-turbocharged, 3.0-liter V6 punching out 367 horsepower and 387 pound-feet of torque, we're betting this would be the AMG Sport variant, rather than your everyday GLC. 4Matic all-wheel drive is a must-have in this segment, and it's present here, while a nine-speed automatic transmission is responsible for distributing power. The Concept GLC Coupe will be shown this week at the 2015 Shanghai Motor Show. Check back then for more. Mercedes-Benz Concept GLC Coupe The next coup Stuttgart / Shanghai. In a flowing transition, Mercedes-Benz lands the next coup: the Concept GLC Coupe is a near-production-standard study that carries the successful GLE Coupe formula over into a more compact segment.
