Cadillac logo losing its wreath?

The easily recognizable Cadillac logo dates back to the company's founding in the early 1900s, but over the last 110 years, there has been an on-again, off-again love affair with the wreath surrounding the crest. Cadillac's current badge design has used the wreath since the 1980s, but Automotive News is reporting that GM's luxury division is planning to ditch the laurel wreath for a cleaner-looking logo.
The new logo could make its debut as early as next month on a new concept car that will be revealed at the Pebble Beach Concours d'Elegance, although the report also says that it might be until 2015 before it makes its way to a production car. Even then, it doesn't like anything has been finalized yet, as the article also says that plans could still change.
As Cadillac looks to improve its global presence as a luxury automaker, the report says that a simpler logo could make it easier for designers to incorporate the badge onto the car - either in the grille or above the grille (possibly in a fashion similar to Mercedes-Benz). Head on over to the AN article, which shows the Cadillac logo dating back to its earliest design.

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:

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.
