Cadillac Escala Concept shows off a softer side of American luxury

When Cadillac announced that it would be appearing at Monterey Car Week with a stunning, new concept, the news sent a rush of blood to the head. Would it be a CT6 Coupe? A new V-series model? A follow-up to the show-stopping Elmiraj? Tonight, at the beginning of a weekend of festivities to tantalize automotive enthusiasts and aficionados, Cadillac instead showed off a glimpse of reality: the Escala four-door coupe concept. It wasn't behind a flat-white background, but at a futuristic yet modern home nestled in the hills that Cadillac president Johan De Nysschen introduced the Escala as a "point of inflection" for the brand. Keen observers will note that "Escala" is nearly "Escalade," but any similarity between the two vehicles ends there. De Nysschen noted that the four-door is meant to "relentlessly drive this brand back to its place at the pinnacle of premium." "Nothing less will do," de Nysschen said. The Escala is neither as bold as some recent Cadillacs to take the stage, nor as brash. From a distance, it has a wide, muscular stance wrapped in a tailored suit. Up close, it almost resembles a four-door Camaro — perhaps a nod to the work of former Holden design chief and incoming General Motors director of design, Michael Simcoe. De Nysschen described the Escala project as an "opportunity for designers to flex their creative muscle." The Escala seems to have a footprint mirroring that of a Mercedes-Benz CLS-Class, but it feels wider and smaller at the same time. Is the shape derivative? Perhaps, but the Escala's design is less a reflection of a future, incognito Cadillac, and more of a chance for the brand to show off the details that might soon become icons. The Escala's shape may not be earth-shatteringly different, but the truth is in its details. The mirrors are as thin as designer spectacles. The C-pillar offers an opportunity to show off Cadillac's latest take on the Hoffmeister kink. A glass roof adds visual airiness. And a simple "GM DESIGN" badge sits below the side doors, in deference to the stylists who labored to make the Escala different. The most defining element of the concept is the way it utilizes light. There isn't anything blinding about its lighting, but that means you can focus on the shape and appreciate the ambience. The depth of the LED tail lights adds visual length to the Escala and shows where Cadillac's designers placed the most importance. It's contrast and beauty at once.

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.

GM puts e-commerce shopping in car dashboards

DETROIT — General Motors on Tuesday said it will equip newer cars with in-dash e-commerce technology, betting it can profit as drivers order food, find fuel or reserve hotel rooms by tapping icons on the dashboard screen, instead of using smartphones while driving. GM's Marketplace technology, developed with IBM, will be uploaded automatically to about 1.9 million model-year 2017 and later vehicles starting immediately, with about 4 million vehicles across the Chevrolet, Buick, GMC and Cadillac brands equipped with the capability in the United States by the end of 2018, GM said. GM will get an undisclosed amount of revenue from merchants featured on its in-dash Marketplace, Santiago Chamorro, GM vice president for global connected customer experience, said during a briefing for reporters. Customers will not be charged for using the service or the data transmitted to and from the car while making transactions, he said. "This platform is financed by the merchants," Chamorro said. GM will get paid for placing a merchant's application on its screens, and "there's some level of revenue sharing" based on each transaction, he said. It is too soon to say how much revenue GM could realize from the Marketplace system, he said. The GM Marketplace will compete for customer clicks and revenue with hand-held smartphones, which offer a far richer array of applications than the GM system will at the outset. Amazon.com is partnering with other automakers, including Ford, to offer in-car e-commerce capability through Amazon's Alexa personal assistant system. For example, GM will launch Marketplace with just Shell and Exxon Mobil icons in the fuel category. The only restaurant available for in-car table reservations at launch is the chain TGI Fridays, GM said. In addition, there will be apps for parking, and ordering ahead at coffee shops and restaurants such as Starbucks, Dunkin' Donuts and Applebee's. "We will be adding more vendors," with some coming in the first quarter of 2018, Chamorro said. In addition, he said GM plans to expand integration into its vehicles of music, news and other information services. GM also hopes to use its in-car Marketplace connections to expand purchases of products and services, such as additional access to in-car wifi, from its own replacement parts business and dealer network. Customers can "expect to see more service promotions coming through the platform," Chamorro said. Reporting by Joe WhiteRelated Video:
