Forget everything you know about Cadillac V

Cadillac rolled out the CT4-V and CT5-V performance sedans to a rather confused group of journalists last night. What are these cars? Only 355 horsepower in the CTS-V replacement? And just 320 horsepower for the ATS-V successor? Surely, there's something out of place — you can get up to speed with all the details here. Cadillac understood our confusion and explained what was going on rather quickly. The explanation means you have to forget everything you know about what "V" means for a Cadillac, though. Any Cadillac with the singular "V" badge on it previously has denoted the absolute top-tier of performance for that particular model. The CTS-V had the Corvette Z06 engine in it and made 640 horsepower. The ATS-V had a boosted 3.6-liter V6 good for a raucous 464 horsepower. They were equivalent to BMW M, Mercedes-AMG or an Audi RS. We're not talking about the lesser M or AMG models, either. No, the last Cadillac Vs were meant to compete with cars like the C63 or M3, the top-tier of performance in those brands' lineups. This is where you're going to have to start re-learning, because that's no longer the case for a Cadillac with a V badge gracing the rear end. What Cadillac has essentially done is demote what V means, with the intention of offering "something else" above it. With this new strategy, we'd equate a Cadillac V to something like an AMG 43, M340i, or Audi with an S badge on it. Cadillac has even come out with a car similar to this strategy before in the V-Sport. That didn't confuse everybody, though, because the name was different, and the strategy was clear. Now, Cadillac V is just a small stepping stone to these mysterious high performance cars still to come. We asked for any information concerning these future track-ready, fire-breathing monsters, but mum is the word for now. The naming strategy for something above a V is uncharted territory, and it'll also force everyone to learn what the top of the Cadillac lineup is all over again.

Think future vehicles like an XT5-V, XT4-V and others like that. Now that V doesn't mean a Nurburgring-conquering 500+ horsepower luxury muscle car, it makes it far easier for Cadillac to get V badges on everything. Obviously, GM isn't the first to think of this strategy.

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:

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.
