Cadillac XT5 platform to underpin three-row crossover

Cadillac just launched the XT5 crossover to replace the SRX. But that's only the start. Speaking with Automotive News, Caddy president Johan de Nysschen confirmed that a new three-row crossover is also on the way. The seven-seater is based on a stretched version of the flexible platform underpinning the XT5, which we just drove recently. Taking that approach will give the luxury brand a larger crossover to pit against the likes of the Infiniti QX60, Audi Q7, and Volvo XC90 without having to develop one from scratch. It will also give buyers a more car-like alternative to the larger, truck-based Escalade. "It's one of the benefits of having this very flexible architecture. We can expand it, make it longer and wider. That gives us the ability to develop the car very quickly, as opposed to starting from scratch," de Nysschen told AN. "It's not running yet. It is a program request that we initiated with the engineers only last year. They are working at remarkable, record-breaking speed to get us the car." The new model would likely be called the XT7 and offer similar levels of equipment to the existing, smaller XT5. The existing mid-size model packs a 3.6-liter V6 mated to an eight-speed automatic transmission and comes in four trim levels. Related Video:

Super Cruise will feature in 22 GM nameplates by 2023

Super Cruise, the semi-autonomous hands-free driving technology that first appeared on the 2018 Cadillac CT6, was always intended to broaden out to more GM models, especially now that CT6 production has ended, but now we have specific numbers. Automotive News reports that GM will have it on 22 nameplates by 2023. GM President Mark Reuss spilled the beans to investors at the company’s Capital Markets Day presentation, saying that Super Cruise will start appearing in brands beyond Cadillac in 2021. GM just last week announced the first big update for its driver-assist technology late last month, saying it would be coming to the 2021 CT5, CT4 and Escalade full-size SUV, all of which should debut later this year. Next year weÂ’ll see it offered as an option on seven more nameplates, then a dozen more in 2022 and 2023, Reuss said. The next generation of the technology will come with a new feature called “Lane Change on Demand,” which will allow the driver to activate or tap the turn signal and the car to do a hands-free lane change if itÂ’s safe to do so, and so long as the driver monitor system can tell the driver is paying attention. ItÂ’s also said to feature improved performance and hands-free dynamics, a better user interface and software tweaks, among other upgrades. Super Cruise uses a camera and infrared light to detect whether the driver is paying attention, plus radar, cameras and lidar mapping to center the vehicle in a highway lane and drive in hands-free mode in optimal scenarios. ThereÂ’s no immediate word on whether the upcoming next-generation version will also come with an expanded network of compatible highways beyond the 200,000 miles where the technology is currently capable of being deployed. Autoblog named Super Cruise the 2019 Technology of the Year winner. Related Video:     Cadillac GM Emerging Technologies

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.
