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.

2015 Australian Grand Prix all about grooves and trenches [spoilers]

We can't remember the last time 90 percent of the action in Formula One had nothing to do with cars setting timed laps. Yet that's was the situation at the Australian Grand Prix, continuing the antics from a scarcely believable off-season with blow-ups, driver and team absences, a lawsuit, and a clear need for some teams to get down and give us 50 pit stops. Nothing much has changed from a regulation standpoint, and at the front of the field nothing has changed at all. Lewis Hamilton in the Mercedes-AMG Petronas claimed the first position on the grid like someone put a sign on it that read, "Reserved for Mr. Hamilton;" teammate Nico Rosberg was 0.6 behind in second, Felipe Massa in the Williams was 1.4 seconds back in third. Sebastian Vettel proved that Ferrari didn't do another Groundhog Day routine this off-season, slotting into fourth. His teammate Kimi Raikkonen was not even four-hundredths of a second behind, ahead of Valtteri Bottas in the second Williams, Daniel Ricciardo in the first Infiniti Red Bull Racing, and rookie Carlos Sainz, Jr. in the first Toro Rosso. Lotus, now powered by Mercedes, got both cars into the top ten with Romain Grosjean in ninth, Pastor Maldonado in the final spot. However, even though the regulations are almost all carryover, in actual fact, everything has changed this year. Mercedes is even faster. Renault is even worse. Ferrari and Lotus are a lot better. Toro Rosso is looking like anything but a junior team. And McLaren is – well, let's not even get into that yet. Furthermore, this weekend was shambles: 15 cars started the race, the smallest naturally-occurring grid since 1963. Manor couldn't get its cars ready before qualifying. Bottas had to pull out after qualifying when he tore a disc in his back and couldn't pass the medical clearance tests. The gearbox in Daniil Kvyat's Red Bull gave out on the lap from the pit to the grid, and to give misery some company, the Honda in Kevin Magnussen's McLaren blew up on the same lap. When the lights went out, Hamilton ran away and was more than a second ahead of his teammate at the end of Lap 1. The advantage disappeared, though, because behind him, at the first corner, we got our first pile-up. As Raikkonen drove around the outside of Vettel at the right-hand Turn 1 it looked like Vettel, going over the kerbing, hopped to his left and bounced into Raikkonen.

Genesis cars win accolades, offer value — so why are sales so bad?

My high-school buddy Brent Cormier was so smitten with the Genesis G80 when he saw it at an event I hosted at SXSW in 2016 he bought a used 2013 Hyundai Genesis a short time later and fell in love with the car. "It surpasses my every expectation," said Cormier, a self-described "renaissance man" who owns and runs a real estate agency with his wife Laura, is a food service executive chef and part owner of Austin-based Thin the Herd Guitars. "I was locked into Mercedes and Audi for 10 years," he added. "And felt trapped in an endless pit of maintenance costs." After owning the Genesis over the past two years — including using it as an Uber and Lyft driver to earn extra cash — Cormier learned what some frugal luxury sedan buyers and a handful of car reviewers have discovered: Genesis offers great bang for the buck compared to other premium brands and can compete with the best in terms of performance, features and comfort. Hyundai's luxury brand also earned a prominent third-party endorsement last week when for the first time Genesis topped J.D. Power's 2018 APEAL study, surpassing German luxury-performance icon Porsche. The APEAL study (which stands for Automotive Performance, Execution and Layout) "measures owners' emotional attachment and level of excitement across 77 attributes," ranging from performance to comfort, and asks nearly 68,000 owners of new 2018 models to score vehicles on a 1,000-point scale. In its second year ranked as a stand-alone brand, Genesis earned an APEAL score that bumped it up 15 points to 884 and helped push it past Porsche — and past BMW, Lincoln, Mercedes-Benz, Audi, Volvo, Cadillac, Land Rover and Lexus, in order of ranking. Last month, Genesis also topped J.D. Power's Initial Quality Survey (IQS) for the first time this year. And both its models were awarded Top Safety Pick Plus ratings by the Insurance Institute for Highway Safety, among 11 Plus ratings in all for Korean vehicles. Despite high J.D. Power rankings and great reviews, Genesis U.S. sales were off 50 percent for the first six months of 2018 compared to 2017, and in June Genesis sold only 796 vehicles — the first time U.S. numbers dropped below 1,000 in a month. Part of Genesis's APEAL and IQS success can be attributed to its small product lineup: just two models, the G80 and G90 sedans, with a third, the 2019 G70, launching later this year. And while those numbers may help in J.D.
