Cadillac says it made CUE infotainment a lot better

We've never been huge fans of CUE, the Cadillac User Experience infotainment interface. It's been around a few years now, and the best thing we can say for it is that it now supports Android Auto and Apple CarPlay, making it easy enough to replace most of the interface with a familiar smartphone-based system. Now Cadillac has made some big upgrades to the system that should address at least some of our concerns. First and foremost, the system is claimed to be more intuitive, with a more logical interface design. Cadillac has added a Summary View that gives an overview of the climate, media, navigation, and phone all at the same time. The system will also be able to receive over-the-air updates, allowing Cadillac to make improvements more often and push them out to owners' cars, mush like Tesla and other automakers already do. The 4G LTE connection will also be used to connect the car with the cloud, where drivers can store and modify their own personalized set of settings. This My Driver Preferences profile will include things like contacts, navigation preferences, and recent destinations, and will also follow them from one car equipped with the system to another. That should come in handy for anyone subscribing to the $1,500-a-month Book by Cadillac vehicle subscription service, which allows participants to swap between cars when they choose. The cloud connection will also carry over to a new available navigation function, which Cadillac claims has a more intuitive, smartphone-like interface. It uses its data connection to provide current destination info and is supposed to learn a driver's habits, such as their preferred routes and frequent destinations, which the system will then attempt to offer up predictively – so the car should be able to know that you're heading home at 5:00. Additional apps for the system will be available through Cadillac's new Collection app store. And it's still compatible with Android Auto and Apple CarPlay. One sore spot that appears to have been improved is the digital gauge package, although Cadillac hasn't offered details on that extension of the system. The current iteration's ability to over-customize the interface (our personal favorite is the option to display a total of four speedometers between the head-up display and the gauge screen; see video below) and unintuitive controls make it difficult to use and learn, while the simulated gauges don't look particularly realistic.

GM may have teased a whole group of electric vehicles

During GM's big CES press conference, the automaker highlighted a number of its upcoming electric car-related projects from delivery vans to the upcoming flagship Cadillac Celestiq. In the middle of it all, a collection of mystery cars sat in the background behind speakers. They were in the dark, lit only with their running lights, and while it's possible they're just generic filler cars or concepts, we think they could be future products. Our best shot of the cars together is shown above, and we can pretty easily identify three of the vehicles. In the center is obviously the GMC Hummer EV. On either side of it are Cadillacs. To the left seems to be the Lyriq crossover, and to the right is the Celestiq sedan. Two of these cars have production dates, and the third has been confirmed for eventual production, just without timing. This is why we think the rest of the cars are upcoming models. The next most easily identified car is on the near right behind the Cadillac Celestiq. It very clearly has a Chevy bowtie illuminated in the running lights. And looking closely, it appears to be a pickup truck. It's difficult to make out anything more than that. The nose does look a bit more rounded and swept back than the brick-like designs of the Silverado truck line. That also squares with what seemed to be the upcoming truck that appeared in the background of yet another GM presentation. GM previously said this electric Chevy truck will be a full-size model with up to 400 miles of range. That leaves us with three more mysterious models. Over to the left behind the Cadillac Lyriq are what appear to be a pair of crossovers. The one on the far left looks low, curvy, and possibly with a fastback roof. The one on the right is taller, boxier, and probably more of a full-size people hauler. It's hard to say much more beyond that. They could be new electric Buicks, which would fit in nicely with that brand's crossover portfolio, and would likely be highly successful in China, where Buicks, crossovers and electric cars are all rather hot commodities. As for the mystery car on the far right, it's quite a puzzle. We can at least rule out Buick and Cadillac, and GMC since it's definitely a car, and a rather small one compared with the other cars on display. That leaves Chevy, and possibly the autonomous division Cruise. We're leaning toward it being a Chevy, since the first Cruise vehicle is going to be a boxy pod of sorts.

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.
