2016 Mercedes-Benz C450 AMG Sport First Drive

A. M. G. Those three letters carry a lot of weight, especially to those who firmly believe that AMG is the hallowed performance pinnacle of the Mercedes-Benz brand. Those purists probably lifted an eyebrow at the front-drive platforms behind the CLA45 AMG and GLA45 AMG, and virtually every AMG-branded SUV that has hailed from the tuner-focused nameplate. But they might want to consider a second look at the 2016 Mercedes-Benz C450 AMG Sport. No, it's not a full-blown, fire-breathing AMG like the C63, and it doesn't get the newfangled "Mercedes-AMG" nomenclature. But after spending some seat time in the C450 AMG Sport, there's a decent chance you'll be quite alright with that. Inside and out, the C450 bears a strong visual resemblance to the mean looking, V8-powered, 469-horsepower C63 and its even fiercer, 503-hp, C63 S variant. The C-Class cockpit feels a bit snugger than you might expect considering its exterior proportions, particularly from the passenger seat. On the other hand, the new C-Class is also quite a bit more nicely appointed than its predecessor, which has inspired more than a few comparisons to the super posh S-Class. As for the C450 AMG, its more purposeful design cues and sportier details lend it a buttoned-down, modern feel. The biggest differentiator between the C and CLA class, however, is the rear of the cabin: the C's back seats are considerably roomier than the entry-level CLA's posterior perches. In place of V8 power, the modest 450 AMG packs a more reasonably endowed twin-turbocharged, 3.0-liter V6 that pushes 362 hp and 384 lb-ft of torque through a 7G-Tronic Plus automatic gearbox (in place of the the C63's dual-clutch seven-speed). Power is routed through all four wheels with a 66-percent rear, 33-percent front torque split. For some numerical context, the C450 AMG exceeds the C400 by 33 hp and the C300 by 121 hp, while it lags behind the C63 by a rather significant 107 hp. Crucially, the six-banger helps shed between 231 and 242 pounds compared the C63 models – this, despite a heavier all-wheel-drive arrangement, as opposed to the C63's rear-drive configuration. The C450 AMG shares a few pieces of hardware with its big brother AMG sibling, including the front axle, electromechanical steering, and upgraded brake setup (though you can't get carbon ceramic stoppers like you can in the C63 S).

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.

Apple lends prestige to a new Mercedes-Benz music system

Not often does Apple offer its name to products or technologies that emerge from beyond the walls of Fortress Cupertino. Could a partnership with Mercedes-Benz signal the start of something new? Mercedes’ new audio system unveiled this past weekend centers on the integration of Apple MusicÂ’s Spatial Audio with Dolby Atmos surround — a music enhancement generally heard in headphone-listening environments — in selected (and optional) Burmester audio systems. Plans are to offer the components initially in the Mercedes-Maybach S-Class, the S-Class as well as the EQE, EQE SUV, EQS and EQS SUV. No prices for the options were announced. Also partnering in the project is the Universal Music Group, one of the worldÂ’s leading music publishers. According to Mercedes, the Dolby tech “empowers musicians and audio engineers to place discrete audio elements or objects in a three-dimensional sound field, which goes beyond the capabilities of standard stereo productions. The system adapts to any playback environment, meaning fans can listen to music with unparalleled clarity that matches the artist's original vision in the studio.” We would expect no less from 31 speakers in a Maybach, powered by a pair of amps churning out 1,750 watts. Imagine Keith Richards cranking guitar through 31 speakers in an enclosed car cockpit. Almost three out of four music consumers say that they listen mostly in a car, says Mercedes Chairman Ola Kallenius. ”Through this exceptional partnership, we are giving our customers the extraordinary in-car audio experience they expect from Mercedes-Benz,” he said. “Both Apple and UMG share our vision and values and, together with Dolby, we will create a seamless and unique experience for our customers." Partnerships between automakers and audio companies have become common in recent years, and there have been mixed results from systems attempting to create a "surround sound" experience that goes beyond stereo. Bose put its systems into General Motors cars decades ago, and others followed, including Bowers & Wilkins, JBL and even the legendary McIntosh. Most recently, famed Italian speaker designer Sonon faber found a home in Maserati's new Grecale, and British speaker maker KEF is working with Lotus.
