2013 North American Car and Truck/Utility of the Year finalists announced [w/poll]

2012 is almost in the books and automakers are spending December gearing up for the 2013 auto show season, which tips off next month at the Detroit Auto Show. Traditionally, the latter opens up with the announcement of the North American Car and Truck/Utility of the Year awards, and this year figures to be no different.
But up until this moment, we didn't know which six vehicles would be parked ahead of the stage as finalists, with executives and engineers waiting for the winners to be disclosed. Whittled down from October's "short list" of nominees (11 cars and 10 truck/utility vehicles), the finalists are as follows:

Cadillac recalls 17,500 SRX CUVs in Canada

When reporting on recalls, Autoblog generally tries to focus on the US market. However, a recent campaign in Canada seems important enough to be worth mentioning because it could eventually affect American drivers. General Motors is repairing 17,481 Canadian examples of the Cadillac SRX from the 2010-2015 model years because of the possibility of a loose nut in the rear suspension. For the moment, the automaker hasn't yet announced whether the CUV in the US would require a similar campaign.
The notice was dated September 18, 2014, on the website for Transport Canada, similar to the National Highway Traffic Safety Administration in the US. It says, "the rear suspension toe link jam nuts" might not have been sufficiency tightened, which could allow a rear wheel to turn "inboard or outboard" while driving. If this happens, it could cause a sudden change in handling. Canadian Cadillac dealers are inspecting the parts and replacing the toe link if necessary.
This campaign isn't listed on the GM's running recall tally from September, which includes exported models, but it does list four other campaigns for the SRX this year - three in this range of years and one for the 2004-2006 model. Autoblog reached out to the company to ask about the possibility of this recall expanding to the US and were told "We have not publicly announced US recalls" for the issues affecting the SRX. The New York Times was given a similar quote. Scroll down to read the notice from Transport Canada.

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.
