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.

Lamborghini Countach, Ferrari 512M and more immortalized as Lego sets

Lego has announced a slew of new Speed Champions sets, the ones based on actual licensed cars, for 2022. The latest batch includes a smorgasbord of supercars, from beloved classics like the Lamborghini Countach to yet-to-be-released promises like the long-awaited Mercedes-AMG One. There are seven cars in total, released in five sets.  Our favorite is probably the 262-piece Lamborghini Countach, based on a later LP500 variant. Not only does it tick the box of a childhood dream machine, but the angular shape of the real-life Countach lends itself well to being recreated in Lego bricks. Also, it's modeled in white rather than the typical red. Lego Speed Champions Ferrari 512M 1 View 6 Photos We also really dig the Ferrari 512M. It marked the last of Ferrari's V12 endurance racers, and even though it was soundly spanked by the Porsche 917, the cars are undeniably beautiful. The 291-piece Lego set does a great job of capturing its brutal wedge silhouette in brick form. Lego Speed Champions Lotus Evija 1 View 5 Photos Rounding out the single-car sets is the 247-piece Lotus Evija. The electric Lotus has a bit of a generic supercar look about it, but that's not entirely the fault of the Lego kit. Its dramatic vents can't really be replicated with the limited "resolution" of the Lego bricks. Its rear, with unique taillight-encircled air tunnels, is a bit more distinctive. Lego Speed Champions Aston Martin Valkyrie AMR & Vantage GT3 1 View 7 Photos In addition to the single car sets, there are two larger sets of two cars each. One is a 592-piece Aston Martin-themed pack that includes the Valkyrie AMR Pro and Vantage GT3. Again, it's a bit difficult to sculpt the cars' curvaceous lines out of straight-edged bricks, but the effort is admirable. The Valkyrie is probably the more successful of the two, as the Vantage would resemble a Corvette or Viper if it didn't have stickers to clarify the details. Lego Speed Champions Mercedes-AMG F1 W12 E Performance & Project One 01 View 9 Photos Last but not least is a twofer comprised of 564 bricks to build the Mercedes-AMG One and seven-time Formula 1 world champion Lewis Hamilton's W12 racer. In Lego's official product description the driver is not mentioned by name, but the number 44 gives it away. The model of the One indeed looks like a sharp supercar, but the blocky pieces don't exactly replicate the lines we've seen on camouflaged test mules.

Aston Martin and Mercedes-AMG formalize technical partnership

The development of a partnership between Mercedes-Benz and Aston Martin has been a long time coming. The news dates back to 2008, and over the five years since was supposed to lead to a rejuvenation of both the Maybach and Lagonda brands. That program ultimately fell apart, but the tie-in was forged afresh in July when the two automakers signed a letter of intent over a renewed partnership. And now that partnership has been formalized.
In a deal just announced, Mercedes-AMG will build a new V8 engine for Aston Martin that will power a new generation of luxury GTs for the British marque, presumably to replace the 4.7-liter V8 in the Vantage. The relationship appears to be similar to the one already in place between AMG and Pagani, only in this case, will involve Daimler taking as much as a five-percent stake in Aston Martin and an observer seat on Aston's board.
The technical partnership is also set to lead to the supply of electric and electronic systems, and could incorporate "additional areas of cooperation in the future." Whether that will include a fresh attempt at reviving Lagonda remains to be seen, as does the future of Aston's long-serving, Ford-based 6.0-liter V12 engine. But for now you can read the full announcement below.
