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.

Lexus NX, BMW i3 to get Super Bowl commercials

At this point last year, we'd been getting news on automotive-focused Super Bowl commercials for more than two months. The teasers hadn't come out yet, but manufacturers lined up for the super-expensive spots were making their intentions known. This year? Almost nada, until this week. BMW has said it will air a 60-second spot promoting the i3 during the first quarter of the game, the Munich firm returning to The Big Game after a four-year absence. BMW says, "Big ideas like the BMW i3 take a little getting used to, and the creative idea surrounding our spot will play on this analogy." We say that pitching a tiny range-extended hatchback during the beer-iest American sports orgy of the year should make for some neat commentary afterward. Lexus is putting its new NX crossover in the second Super Bowl commercial it's ever aired, eschewing the glitter of celebrities and glamor for a straight-shooting spot and the tagline, "Be seen, be heard, make some noise." Joining those two are Kia, Mercedes-Benz, Nissan and Toyota. The six confirmed carmakers are down from eleven last year, when car spots made up a quarter of the total ad time. The price to do business for 30 seconds this year: reportedly around $4.5 million, up a stacks from last year's $4 million. You can watch the Lexus commercial in the video above, and beneath that, the BMW press release below has a bit more information on its effort. BMW to Advertise All-Electric BMW i3 during Super Bowl XLIX. The all-electric BMW i3 is featured in a 60-second spot during Super Bowl XLIX on Sunday, February 1, 2015. Woodcliff Lake, NJ – January 15, 2015... Today, BMW announced plans to feature the all-electric BMW i3 in a 60-second spot during Super Bowl XLIX on Sunday, February 1, 2015. After a 4-year hiatus, BMW will be returning to the big game with a commercial during the first quarter. "As one in three Americans will tune in to watch the Super Bowl, we are thrilled to use this platform to educate viewers on the importance of electric mobility," said Trudy Hardy, Vice President of Marketing, BMW of North America. "Big ideas like the BMW i3 take a little getting used to, and the creative idea surrounding our spot will play on this analogy." BMW i is BMW's forward-looking and sustainable brand dedicated to solving many of the mobility challenges faced by the world's most densely populated cities. The BMW i3 is the first of the BMW i vehicles constructed from the ground up primarily of carbon fiber.

Mercedes-Benz GLK coupe to get 2016 intro

Radio chatter around the emerging small, premium crossover coupe genre has thus far been dominated by the Land Rover Evoque and the Mini Paceman. According to a report in Car, the Mercedes-Benz GLK-Class (shown above) has received its invitation to the party and will spend the next three years getting ready: it's said that two-door variant of the crisply-angled CUV is coming in 2016, along with a redesign befitting its sleeker intentions.
To be based on the MRA platform - the rear-drive version of the company's three new modular platforms, it will also support the coming 2013 S-Class and could eventually get an AMG version to help it compete with segment offerings like the forthcoming Porsche Macan. Not much else is known about it beyond its name: Car says it will be called the GLC, a friendly nomenclature we remember best as a Mazda hatchback (allegedly for "Good Little Car"). Internet oldtimers may remember the Mazda GLC as the predecessor to the 323 (which in turn came before today's Mazda3). Either way, the GLC is not to be confused with the larger upcoming BMW X6 rival based on the ML-Class (reportedly called GLS) which is also said to still be in the works, or the front-drive based GLA, a model also edging toward production.
