Consumer Reports declares most and least loved cars [w/video]

Consumer Reports is crunching the numbers from its annual owner-satisfaction survey, and part of that process is finding out how attached drivers are to their cars. CR simply asks readers of models up to three years old if they would buy the same vehicle again in light of their entire ownership experience, and tallies the results. After looking at the responses for about 350,000 vehicles, it turns out that people really love a certain California-built, electrically powered luxury sedan. That's right, this year's the overall winner was the Tesla Model S with a whopping 98 percent of owners saying they would purchase another one (the Model S also won this award last year, with 99 percent satisfaction). The Chevrolet Corvette Stingray came in a close second with 95 percent of drivers hoping to park another one in their garage. A few models weren't quite so favored, though. The Nissan Versa Sedan was the least loved model among its owners; a mere 42 percent said that they would purchase another. The aging Jeep Compass didn't do much better, with just 43 percent of drivers willing to buy the softroader again. On average, about 70 percent of owners say they would buy their car again, and only four cars ranked below 50 percent in CR's findings. Check out the video above to see some of the winners and losers in a few of CR's categories. If you're a subscriber, you can check out the full list on its website.

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.

Weekly Recap: An '80s encore in the auto world

The '80s returned in a big way this week, as National Lampoon's, Ghostbusters, Miami Vice, and even Tetris were back in the news. While there were far more serious topics (see below), nostalgia mingled with modern marketing to put these Reagan-era favorites back in the spotlight. The '80s were alternately cold and corny at times, but their cultural touchstones can still generate big money. That's why Infiniti recreated an iconic scene from National Lampoon's Vacation (1983) for an advertisement that hawks the QX60 crossover. Actor Ethan Embry, who played Rusty Griswold in a later Lampoon's movie, pilots the Infiniti – which is serving as a modern Family Truckster – for a trip to Walley World. A blonde pulls alongside in a red Lamborghini. They flirt, and she drives on. Christie Brinkley, who played the original girl in the red sports car (she drove a Ferrari in the '83 flick), is riding shotgun and chides Embry with: "A blonde. In a convertible. Seriously?" Okay, it's hardly on the level of "here's looking at you," or even "you can't handle the truth," but it should resonate with '80s babies, many of whom are now having children of their own and moving into three-row SUVs like the QX60. Naturally, Hollywood is going back to the well, too, with a Vacation remake that premiers July 29. Meanwhile, Ghostbusters is returning next year, and director Paul Feig offered a peak at the new Eco-1 in this tweet. In the 1984 classic, the team drove a modified 1959 Cadillac. Now, it will drive a late '80s Cadillac. As expected, the announcement generated support and controversy from movie and car enthusiasts. His tweet had generated several thousand retweets and favorites in the days following the news. Though the '80s Caddy looks, uh, less elegant in comparison to the now-iconic fins and curves of the original Ecto-1, it's about the same time lapse into the past as the '59 Caddy was to viewers in 1984. Speaking of 1984, Miami Vice, which debuted that year on NBC, is seeing one of its hero cars hit the auction block, Mecum Auctions announced this week. The 1986 Ferrari used on the show will be offered for sale Aug. 15 during Monterey classic car week. The white supercar runs a 390-hp flat 12-cylinder engine paired with a five-speed manual transmission and was in storage after the show ended in 1989 until earlier this year. It has 16,124 miles on the odometer and is authenticated by Ferrari North America and Classiche.
