Cadillac rushing update for laggy CUE infotainment system

BMW's innovative iDrive was introduced in 2001, and a dozen years later, automakers are still learning hard lessons about what consumers want in their infotainment systems. In response to owner feedback - and a few media drubbings - about the delayed and occasionally fickle responses of its CUE (short for Cadillac User Experience) system, Cadillac has told Wired that it's going to issue an update this year.
Coming for the XTS and ATS, the new software will mean quicker haptic feedback to driver inputs on the touchscreen and the buttons, and snappier responses on screen. Down the road, Cadillac's VP of marketing says that a different mix of screen controls and hard buttons is "something you'll be seeing in the future" - the system is presently a mix of touchscreen-based controls and capacitive-touch switchgear - there are no knobs or physical pushbuttons to speak of, and the omission of both has proven to be a divisive issue among consumers and industry pundits.
Cadillac hasn't provided a date for when the CUE update will be issued, but it has indicated that the service will be performed by dealers, not sent wirelessly.

Cadillac CT6 beefs up with 400-hp twin-turbo V6

Cadillac's engine lineup is set to get a makeover led by the potent powerplants under the hood of the CT6. Our man Steven Ewing is onsite at an event in Detroit reporting all the details. Here's what we know so far: The CT6's top engine will be a 3.0-liter twin-turbo V6. It's the first twin-turbo with cylinder deactivation, which essentially makes the V6 able to convert to a V4 unit. Power will be 400 horsepower at 5,500 rpm and 400 pound-feet of torque at just 2,500 rpm. No word on what a potential CT6-V would get. The CT6 will also have a naturally aspirated V6 that Cadillac is claiming to be all-new. It's rated at 335 hp at 6,800 rpm and 284 lb-ft at 5,300 rpm. That's an improvement of 14 hp and nine lb-ft compared with today's 3.6-liter V6, and fuel economy increases nine percent. Cadillac says it's the highest output for a naturally aspirated V6 that's SAE-certified and runs on regular fuel. Both of these V6s will have stop/start technology and will be paired to with eight-speed automatic transmissions. The 3.6-liter V6 will also be used in the 2016 CTS and the 2016 ATS. Meanwhile, Ewing reports that Cadillac says the ATS-V is actually more powerful than initially announced, though there are no numbers to flesh that claim out as yet. The brand also plans to offer four- and six-cylinder diesel engines in various vehicles and new V8 options. The CT6 bows at the New York Auto Show. It will use an aluminum-intensive body that reduces weight by 198 pounds compared with a steel setup and continues Cadillac's creased design language used on the CTS and ATS models. The CT6 goes into production late this year in Detroit.

It leverages the latest technology to balance efficiency, performance and refinement in the upcoming, top-of-the-range CT6 luxury performance sedan. The all-new Cadillac 3.0L Twin Turbo is designed to achieve new thresholds of refinement and specific output for the brand's new prestige luxury sedan, which makes its world premiere March 31, at the New York International Auto Show. Production begins late this year at General Motors' Detroit-Hamtramck Assembly Plant.

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.
