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.

F1 Race recap: 2016 Russian Grand Prix same as it ever was

The three-year-old Sochi Autodrom that hosts the Russian Grand Prix combines beautiful scenery with a hallmark turn 3, a tricky turn 13, and two long DRS zones. So far, however, those haven't added up to exciting races after the first lap. Despite an in-race issue with his car's MGU-K, Mercedes-AMG Petronas driver Nico Rosberg aced the weekend with his first career grand slam: pole position, fastest lap of the race, leading every lap, and victory. Behind him, not much happened on the leaderboard after an incident-filled opening lap. The drama started at turns 2 and 3. Ferrari driver Sebastian Vettel lined up in seventh on the grid because of a five-place gearbox penalty, Red Bull's Daniil Kvyat sat next to him in eighth. Kvyat hit the back of Vettel's Ferrari in the braking zone for Turn 2, shoving Vettel into Daniel Ricciardo – Kvyat's teammate. Kyvat then clobbered the back of Vettel's car at the entry to Turn 3, spinning the German into the wall and out of the race. Kvyat probably regrets saying before the race that he would show Vettel "no mercy" on the first lap. At the back of the grid at Turn 2, Haas F1's Esteban Gutierrez hit Force India's Nico Hulkenberg and Manor's Rio Haryanto. Gutierrez continued, both the Force India and the Manor retired. A brief Virtual Safety Car period ensued, then the actual Safety Car emerged for three laps while marshals cleaned up the track. Mercedes-AMG Petronas driver Nico Rosberg nailed the restart and took off for the rest of the race. Teammate Lewis Hamilton battled his own gremlins all weekend but still finished second, 25 seconds behind Rosberg. During the final qualifying session on Saturday Hamilton's car suffered the same MGU-H failure as in China two weeks ago. The problem relegated him to tenth on the grid. In the race, Hamilton fought his way to second place by Lap 19 out of 53 laps and began closing the 13-second gap to Rosberg. On Lap 37, the gap now under eight seconds, Mercedes told Hamilton his car had a water pressure issue. The malfunction forced the Briton to manage his race and settle for second. Afterward, Hamilton said he was certain he could have won if not for the malfunction. The rest of the top ten barely changed throughout the contest. The first five positions on Lap 21 crossed the finish line in that order 32 laps later. Ferrari's Kimi Raikkonen took the final podium position ahead of the Williams duo of Valtteri Bottas and Felipe Massa.

Merecedes-Benz EQS, Ford Mustang Mach-E GT and Subaru Forester Wilderness | Autoblog Podcast #702

In this episode of the Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Senior Editor James Riswick. They've been driving some exciting new EVs, like the Ford Mustang Mach-E GT and the Mercedes-Benz EQS. They also discuss driving the new Subaru Forester Wilderness, as well as the perfectly agreeable Toyota Camry XSE Hybrid. James compares four big-name off-roaders — the Ford Bronco, Jeep Wrangler, Toyota 4Runner and Land Rover Defender — based on their ability to accommodate a big load of luggage. Next they reach into the mailbag for comments on the Genesis GV70, as well as a Spend My Money question about replacing a wrecked Subaru Ascent with another three-row SUV.
