No, Eminem is not giving away the Cadillac Ciel concept, Facebookers

Damn it, Facebook people, stop being so gullible. When you see something on social media that requires you to share or like a status or page in exchange for a chance at winning something, it's almost always a hoax. This goes for iPads, or Bill Gates giving away cash or, yes, an Eminem fan page giving away a Cadillac Ciel. Now, normally we'd simply ignore this utter hogwash, but it's getting some traction on Facebook and, annoyingly, is beginning to clog our newsfeed. Ignoring the fact that the Ciel is a pure concept car that likely can't even be registered for regular use, there are more than a few things that should give this nonsense away as a hoax. First, Eminem has only ever gotten in bed with one automaker – Chrysler. It seems unlikely that he'd defect simply to give away a car on Facebook. Secondly, the page that is putting on the giveaway isn't even a verified page – Eminem's real Facebook fan page has 97 million likes, this one has 622,000. Third, a quick look at the caption for the Ciel's photo, shown above, reveals the sort of grammatical mess that no serious contest would allow. Take a look (sic implied throughout): "Only 24 Days Until Christmas, Can you Imagine yourself driving this Car? I'm about to make that happen, Its Official, I Will be giving away this 2014 Cadillac Ciel to one random lucky fan, all you gotta do is follow these three easy steps, Step 1) Share this photo, Step 2) Like my page, Slim Shady Step 3) Like this photo, Winner Will be picked On December 5th 4 Days Away, Good luck to Everyone!!" We reached out to Cadillac spokesman David Caldwell just for fun. Apparently, this photo and schtick pops up every few months with virtually the same text, only to vanish at the end of the "giveaway." You're as shocked as we are, right? So, once again folks, just because it's on the Internet doesn't mean it's true. If your friends, family and acquaintances are blowing up your Facebook feed and social network channels with this nonsense, be sure to set 'em straight with a link to this story – we're sure the real Slim Shady will appreciate it.

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.

Cadillac boss: Don't ask why we have so many sedans

Ugh, crossovers. Car-based, high-riding station wagons, for some reason, sell in absurd numbers and make automakers lots and lots of money. That's why automakers with a strong lineup of CUVs are running strong, while sedan-heavy brands are struggling. Cadillac is all too aware of this fact. While the company is preparing to launch the new CT6 luxury sedan, it's also realizing four sedans, a coupe, a crossover, and a $73,000, old-school, body-on-frame SUV does not a healthy lineup make. Worse, though, as Cadillac President Johan de Nysschen rued during the LA Auto Show, is that the new CT6 is joining a segment already oversaturated. While it's a big, expensive vehicle, it's not much bigger or more expensive than the CTS and XTS sedans. "Please don't ask me why we have three cars in the same segment," de Nysschen said, stopping midway through an interview with Automotive News on the CT6's market placement to make the crack. "That's a whole different subject." As for those CUVs, the new XT5 debuted in LA, and it will eventually be joined by another much-needed CUV in 2018, AN reports. Related Video:
