2021 Cadillac Escalade will get next-gen Super Cruise with auto lane-change

Super Cruise is getting its first big update since it was originally launched on the 2018 CT6 sedan. As that large car fades away, this new version of Super Cruise will be coming online in the 2021 CT5, CT4 and … the 2021 Escalade! Yes, ladies and gents, Cadillac is finally applying its advanced driver assistant to the iconic Escalade. The biggest change to this version of Super Cruise is a new feature called “Lane Change on Demand.” When Super Cruise is engaged, the driver can tap the turn stalk, and the car will execute a hands-free lane change if itÂ’s safe to do so. This kind of lane-change functionality is similar to that offered by other manufacturers' systems (i.e. Mercedes-Benz, Tesla, BMW). However, like the rest of Super Cruise, the car is able to complete the task with the driverÂ’s hands completely off the steering wheel so long as the driver monitor can tell that youÂ’re paying attention. Further improvements abound. “This is our most extensive update weÂ’ve made to Super Cruise since its debut,” said Mario Maiorana, Super Cruise chief engineer. “We have made a number of improvements to make Super Cruise more intuitive, better performing and more accessible for our customers. In addition to the automated lane change functionality, weÂ’ve made improvements to the user interface and hands-free driving dynamics.” Cadillac says that it has gathered richer map information to make the lane change function possible and also to make turns and highway interchanges smoother. The software was also improved with the aim of gaining “better steering and speed control.” Cadillac also made the system easier to engage. It did this by allowing the operator to switch the Super Cruise system on, and then get the vehicle in a proper lane position — it automatically activates once the vehicle is positioned. Previously, the driver had to get the vehicle centered in the lane properly, and then you were allowed to switch the system on. The auto lane changing function operates similarly to other systems like it. When driving, you can either tap or fully depress the turn signal stalk. The car then looks for an acceptable opening in the indicated lane. Once found, the car begins its lane change. Within the gauge cluster, there are animations that keep the driver apprised of the lane change at all times. Once the vehicle has moved into the new lane, itÂ’ll shut the turn signal off and continue driving along.

2020 Cadillac CT4 spy shots reveal sedan-heavy approach in age of SUVs

You're looking at some pictures of the 2020 Cadillac CT4, which will be smaller than the upcoming CT5. And since they're both smothered in similar-looking camouflage, which is specifically intended to confuse, you might think they look pretty similar. In isolated photos, it's sometimes hard to tell which sedan you're looking at. In fact, when we first saw this car recently, we also thought it was a CT5. Here's how we know they're actually two different cars. Some background: The CT5 is slated to replace the CTS, and to try and find the balance that the old car couldn't achieve in the lineup. Cadillac's former CEO previously stated that this car would also fill in for the ATS, which is on its way out. Whatever it ends up being, it'll have to make a clear case for itself against the CT6 — it can't be too close in size and opulence, or they'll hurt each other in sales. And the CT5 can't be too small, or it will struggle against traditional midsize luxury cars. The CT4 could further complicate matters for the exact same reasons, just in a smaller package. How small can Cadillac make it? It seems poised to replace the wonderful-to-drive ATS, which was as allergic to sales as the XTS. This will give Cadillac a three-sedan lineup: CT4, CT5, and CT6. Let's hope there's enough differentiation between them to prevent consumer confusion and sales cannibalization — and that consumers understand the CT6's promotion via attrition to top dog in the sedan lineup. With all that out of the way, let's look more closely at the CT4 (above left) and CT5 (right). The CT4's greenhouse stops closer to the centerline of the rear wheels than the CT5's. That gives the CT5 a visually longer, leaner look, more of a semi-fastback arrangement. The CT5's rear vanity window should resemble the CT6's, with a glass element behind the door opening. The CT4 will have a more conventional vanity window in the door, like the ATS. Perhaps the quickest "tell" is the size of the side-view mirrors, which are rounder in the CT4 and leaner in the CT5. Out back, the CT4 has a lower cutout for the license plate than the CT5. The exhaust outlets are also different, although that may change for production. Remember, the big full-width rear lights are probably misdirection on the part of the GM camo team. The entire rear decklid of the CT4 has more roundedness to it, while the CT5's extra width gives it more room up top to spread the decklid out a little flatter.

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.
