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.

Here's how Detroit is selling more luxury vehicles than Germany and Japan

Now there's an attention-grabbing headline, eh? Although the answer to the riddle - pickup trucks and SUVs - might be somehow deflating, the numbers involved deserve a going over. According to TrueCar's figures (click on the table to enlarge), six of the year's ten best-selling vehicles in the US that sell for a transaction price above $50,000 are body-on-frame, and the Mercedes-Benz E-Class is the only foreigner to crack the top five. Every enthusiast knows that pickup trucks are 'Murica's most popular vehicle by a colossal margin, and there have been plenty of reports about the popularity of luxuriously appointed trucks and SUVs, but compare these figures from TrueCar: 70 percent of Chevrolet Tahoe sales have a transaction price above $50K, and The Bowtie is expected to make $3.9 billion in revenue on 66,945 predicted high-dollar sales; 95.1 percent of E-Class sales break $50K, so the German company will make $4.0 billion on 67,006 predicted sales in that pricing sphere. It's about the only time you'll see the Tahoe ranked right next to Mercedes' bread-and-butter sedan. Ram is ahead of those two with $4.2B coming from $50K-plus sales. The Ford F-Series does almost as much revenue as the next three combined, with an expected $10.8 billion coming from sales of trucks over $50K - more than a quarter of the model's total sales, when a base F-150 can be had for about $26,000. Yes, the Germans make a lot more money on fewer sales, but considering the comparison, the bottom line isn't too troubled by such facts. Weighing like-for-like, the full-size Ford walks it in every category; elsewhere, the Chevrolet Silverado outsells the Ram, but the Ram outsells the Chevy by 6.7 percent above $50K. And for all the flak GMC takes over swapping out grilles, the Sierra also outsells the Chevy in the well-appointed segment, 16.1 percent of sales versus 11 percent – the Professional Grade brand is a huge profit center for The General. You'll find more info in the TrueCar press release below. TrueCar finds pickup trucks far outsell premium brands among top 10 vehicles over $50,000 Ford F-Series pickup sales over $50,000 surpass combined BMW 3, 5, 7 Series luxury car sales SANTA MONICA, Calif.

Race recap: 2016 Bahrain Grand Prix was everything good and bad about F1

Nothing was as it seemed heading into Bahrain. We were told team bosses had nixed the qualifying experiment that flunked every test by every measure in Australia, but that didn't happen. The FIA didn't give the teams the option of a wholesale return to the old format, the governing body only held a vote on whether to revert back to the old format in Q3 but stick with elimination gimmicks in Q1 and Q2. McLaren and Red Bull dissented, denying the chance for hybrid rounds. We're surprised none of the smaller teams voted against since elimination qualifying is hardest on them. Given the chance to fix the system again in Bahrain, Formula 1 failed again. The FIA and Bernie Ecclestone don't want to go back to the old system – because the race promoters don't want to go back to the old system – so all we know for sure is that there will be more meetings. We also thought Fernando Alonso would race in Bahrain after being given medical clearance, but a follow-up scan by the FIA showed fractured ribs and a damaged lung, ruling him out. And we thought Ferrari might have the pace to conquer Mercedes-AMG Petronas this year – and they might yet, but not on Saturday. That's why the Bahrain race began with another Mercedes one-two, Lewis Hamilton ahead of Nico Rosberg, Ferrari drivers Sebastian Vettel and Kimi Raikkonen behind. The Australian outback is plagued with rabbits, which must have something to do with how Daniel Ricciardo keeps pulling them out of his helmet; the Aussie got his Red Bull up to a surprising fifth on the grid. Williams drivers Valtteri Bottas in sixth and Felipe Massa in seventh would need to get him out of the way quickly to show what the car can do after an unsatisfying race in Australia. Nico Hulkenberg lined up in eighth for Sahara Force India. As proof the qualifying format failed again with its sophomore attempt, the last five minutes of Q2 were disappointing. Hulkenberg had the track completely to himself for his quali run, the only two cars on track after him were the Williams duo who weren't setting a time, but getting a set of soft tires ready to start the race on. As for Q1, the only reason for on-track action in the last three minutes was because Hamilton flubbed his first timed run. Romain Grosjean continued Haas F1's fruitful start to the season with ninth place, ahead of Max Verstappen in the Toro Rosso closing out the top ten. At the end of a long red light to start the race, Rosberg claimed his right to victory before Turn 1.
