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.

Mercedes-Benz S-Class Cabriolet completes the luxury trinity

In its continuing bid to simply eat the lunch of the Bentley Continental GT, Mercedes-Benz has followed up on the S-Class sedan and coupe with a new S-Class Cabriolet. Aristocrats, take notice. Below the beltline, all is familiar. That means the same stylish sheetmetal, from the chiseled front fascia to the strong character lines to the pert rear end. Expect the cabin's accommodations to mirror the hardtop model. But the third member of the S-Class family differs above the beltline, where we see a sumptuous canvas roof. The three-layered top is, unsurprisingly, quite advanced. It uses a three-layer, acoustically optimized design that promises a quiet ride. The top can be dropped or raised in under 20 seconds and at speeds of 37 miles per hour. Finally, the addition of a canvas cover doesn't do much to the S-Class' aerodynamics, as the cabriolet still returns an impressive 0.29, which compares favorably with the 0.27 of the four-door model (the coupe's CoD isn't available). Opting for the S-Class Cabriolet will entitle you to some additional standard equipment, including Mercedes' AirScarf neck heater. The droptop will also pioneer the German brand's new Thermotronic climate feature, which takes complete control of the HVAC system and makes adjustments based on the findings of 12 sensors and 18 actuators. The sensors include those for interior and exterior temperature, solar radiation, air quality, and dew point, among others. Yes, your S-Class will have a sensor for the dewpoint. Also new to the S-Class Cabriolet – not to mention the S-Class line as a whole – is a 9G-Tronic nine-speed automatic transmission, which is already featured on the SLK-Class and the new GLC-Class. The new 9AT will be limited to the S550, while the new S63 Cabriolet will use the coupe's seven-speed AMG Speedshift transmission. Both engines, meanwhile, mirror their coupe counterparts, with 449 horsepower and 516 pound-feet of torque for the S550 and 577 hp and 664 lb-ft of torque on the AMG model, allowing the latter to hit 60 mph in just 3.9 seconds and reach a limited top speed of 186 mph. Both the S550 cabriolet and its Mercedes-AMG counterpart will make their global debut at the 2015 Frankfurt Motor Show, later this month. Read on for the full press release from Mercedes-Benz.

Race Recap: 2016 Austrian GP is mishaps from start to finish

At the 2015 US Formula 1 Grand Prix, rain mixed up the grid and a first-lap incident cast the die for the race. The Austin, Texas event made highlight reels for those reasons and because it decided the Driver's Championship. At the 2016 Austrian F1 Grand Prix, rain mixed up the grid and a last-lap incident cast the die for the race. The Spielbergring race will feature in this year's highlight reel because it might force Mercedes-AMG Petronas to make some hard decisions about the rest of the season. For the first time this season, Lewis Hamilton converted pole position into a lead through Turn 1, and began slowly pulling away from the field. Teammate Nico Rosberg started from sixth because of a gearbox penalty, but was up to third when he pitted on Lap 11. Mercedes normally pits the lead driver first, in this case being Hamilton, but Mercedes wanted to get Rosberg ahead of the two Ferraris. Hamilton pitted on Lap 22, emerging behind Rosberg because of a slow stop. Sebastian Vettel led the race for Ferrari on Lap 27 when his right rear tire exploded coming down the start-finish straight – an eerie reminder of the 2015 Belgian Grand Prix. The Safety Car rolled out, yet when racing resumed Rosberg stayed ahead. After the two Mercs came in for second stops everyone expected Hamilton to lead, but Hamilton had messed up his in-lap and lost a cumulative 3.3 seconds during his actual stops compared to Rosberg's pit-stop times. The Brit remained second. Hamilton chased his teammate for the final 15 laps. At the beginning of the last lap Rosberg messed up Turn 1 and Hamilton closed in. Rosberg took the inside line into Turn 2 as Hamilton pulled up on the outside, then Rosberg appeared to drive straight on as if he simply wasn't going to turn. Hamilton turned in, colliding with Rosberg and driving over the German's front wing. By the end of Turn 2, Hamilton had the lead and Rosberg had a broken car. The Brit won, the German puttered home to finish fourth. The incident promoted Max Verstappen to second and Kimi Raikkonen to third. Verstappen scored his second podium for Red Bull after his victory in Spain. Conversely, Raikkonen's third place for Ferrari was more gifted scraps for the scuderia. Daniel Ricciardo came fifth in the second Red Bull, Jenson Button delivered a terrific sixth for McLaren- Honda, Romain Grosjean got Haas back in the points, Carlos Sainz, Jr. secured eighth for Toro Rosso, and Valtteri Bottas in ninth for Williams.
