Playboy reveals its 2013 Cars of the Year

Vaunted men's magazine Playboy knows that its readers are nearly as interested in cars as they are in the female anatomy... sorry, we thought we could write that with a straight face. Anyway, the buff-book does occasionally fill some of its spreads with sexy metal, to accent all the rest of the sexiness.
To wit, the magazine has unveiled its feature on the 2013 Cars of the Year. Without giving us much in the way of criteria for the awards, nor a clear framing of the categories ("Responsible Ride" is a particularly challenging concept, especially when you consider that the Mazdaspeed3 was the winner), Playboy has nevertheless highlighted what we assume to be it's favorite 12 or 13 (depending on how you count) cars from the 2013 model year.
Headlining the class is the Porsche 911, which Playboy writers single out for having "remarkable electronic voodoo." BMW M5 is named "Slickest Sports Sedan" though the Cadillac ATS then follows on because "we couldn't resist giving the new Caddy a shout-out." The rest of the picks are pretty conventional (save, perhaps, the Honda Fit EV as "Ace Electric"), even if the categories and methodology are fairly wonky. Cruise through or gallery for a taste or check out the full list, here. The site is safe for work, and you can legitimately (this time) say that you were reading it for the articles.

Cadillac recalls ELR coupe over stability control problems

Cadillac is recalling about 656 2014 ELR models made between September 26, 2013 and February 14, 2014, because of a fault with the electronic stability control system. On cars without adaptive cruise control, it's possible that diagnostics could prevent the system from telling the driver if ESC is on or off.
Cadillac has a software fix ready and repairs begin on April 17. Alan Adler, General Motors' recall and legal spokesperson, tells Autoblog that only about 55 of the affected cars are in the hands of owners. The rest are either on dealer lots or still at the factory. There have been no reported injuries or crashes caused by the fault.
The correction for the stability control system involves a software recalibration of the electronic brake control module that takes around 20 minutes to perform. While they use the same platform, the Chevrolet Volt isn't involved in this recall because it "uses a different a brake control module," said Adler.

GM patent reveals new two-stage turbocharger

Modern turbochargers may be some of the best ever made, but performance is something that engineers are always trying to improve. According to GM Inside News, General Motors (GM) is hoping to alleviate some of the negative aspects of a two-stage turbocharger setup with a newly-patented design. The patent, that was filed on May 19, 2016, reveals a clever bypass system that allows the engine, a four-cylinder unit, to optimize both the low-pressure and high-pressure inlets for its respective functions. According to the filing, a conventional two-stage turbocharger setup is engineered to allow both turbines to operate simultaneously at low and mid engine speeds. At high engine speeds, only the low-pressure turbine works. The setup can't isolate either the low or high pressure side, which can impair low-end performance. GM's new two-stage turbocharger setup looks to eliminate this by linking the high-pressure turbo to the exhaust manifold through the high-pressure inlet duct. The low-pressure turbo is attached to the high-pressure turbo by a low-pressure inlet duct, which is linked to a connecting channel. A single actuator that is housed in the exhaust manifold creates a bypass that can opens the high-pressure inlet or close the connecting channel. Depending on what the engine load and speed is, the ECU guides the actuator—a single rotating spindle with discs corresponding to flanges on the high and low pressure sides—to isolate one of the two turbos. Isolating the turbos allow the respective inlets to be engineered for the best possible fluid dynamic performance. The setup should increase performance and decrease lag. There's no word on what car this setup will make an appearance on, but it will most likely be used in premium vehicles before trickling down to the rest of GM's vehicles.
