GM considering new powertrain options for large SUVs

Aside from the new General Motors offerings, there's not a whole lot of action going on in the fullsize SUV segment. That doesn't seem to be stopping GM from pushing the envelope in the market as Automotive News is reporting that the automaker is looking to introduce some new powertrain options into the Chevy Tahoe (and Suburban), GMC Yukon (and Yukon XL) and the Cadillac Escalade - all have been redesigned for the 2015 model year.
Now, we already know that GM and Ford are collaborating on nine- and ten-speed transmissions for a broad range of applications (including the big SUVs), but this new report says that GM is also considering other options as a way to one-up the competition and, of course, to optimize fuel economy. AN quotes Jeff Luke, executive chief engineer for GM trucks, as saying that "interesting powertrain technologies" are coming including a return of a hybrid SUV and possibly even a diesel engine. Although it sounds like the latter could come down to how customers respond to the 2014 Jeep Grand Cherokee EcoDiesel.

GM removes start/stop from full-size trucks and SUVs with V8 engines

GM is removing start/stop technology from a number of its popular full-size SUVs due to the ongoing chip shortage. This follows the removal of cylinder deactivation technology from some of its trucks, which was also due to the chip shortage. GM Authority first reported the news, but we’ve just confirmed everything with a GM spokesperson.  The following 2021 model year vehicles will be affected: Chevy Tahoe, Chevy Suburban, GMC Yukon, Cadillac Escalade, Chevrolet Silverado 1500 and GMC Sierra 1500. Only versions of those vehicles built with the 5.3-liter V8 or 6.2-liter V8 and mated to the 10-speed automatic will have the tech removed from them. Only vehicles manufactured on or after June 7 will be affected. “By taking this measure, it will enable us to continue production of our high-demand full-size SUV and pickups as the industry continues to rebound and strengthen,” GM said in a statement. Those who ultimately buy one of these vehicles without start/stop technology will receive a $50 discount off MSRP for their troubles. Losing this fuel-saving tech could be a big negative for some, but we know many folks turn it off anyway. Not having to press the button to deactivate start/stop every time could actually be a positive if youÂ’re part of the camp who does that already. 2021 Cadillac Escalade Sport Platinum View 27 Photos On the downside, GM says “most of the affected vehicles will experience a minor reduction in fuel economy.” We donÂ’t have revised window stickers in hand to know how each model will be affected, but any 1 mpg reduction will be rather impactful for vehicles rated as low as these trucks already are. Any reduction will be seen in the city mpg rating, so take the kind of driving youÂ’re going to be doing into account before purchasing. When it comes to greenhouse gas compliance rules, GM says it doesnÂ’t foresee this impacting the companyÂ’s average fleet score. It also intends to begin adding start/stop back to these models as soon as possible, but there will be no retrofit effort made to fit the tech to vehicles already built without it. “Our supply chain organization continues to make strides working with our supply base to mitigate the near-term impacts of the semiconductor situation,” GMÂ’s statement reads. “GM continues to leverage every available semiconductor to build and ship our most popular and in-demand products, including our highly profitable full-size trucks and SUVs for our customers.

Cadillac XT5 confirmed for 2016 as next-gen SRX

Cadillac's entire lineup of 2016 models gets a major infotainment upgrade this summer with improvements to CUE and integration with Apple CarPlay and Android Auto. There's one major exception for now, though. The SRX retains the old system until its all-new generation, called the XT5, debuts early in the 2016 calendar year. "When we transition into all new product lines, we will evolve the naming convention to suit the new classification we have announced. So SRX becomes XT5 next year," company spokesman David Caldwell said in an email to Autoblog. Earlier spy shots and rumors suggest the XT5 might be offered with a turbocharged four-cylinder and naturally aspirated six-cylinder engines, plus a nine-speed automatic transmission. For the rest of Cadillac's models, CarPlay arrives with the launch of the 2016 vehicles, and Android Auto joins later. Using either of them requires a connection via USB, and they add a new projection icon on the CUE screen. Once activated, both systems integrate with driver's phone and incorporate features like navigation, music, and contacts. They can also accept voice commands. Even for those that don't want to hook up a smartphone, CUE should work better thanks to a more powerful processor. Start-up times for the infotainment system are expected to be faster, and Cadillac claims that it's also more responsive for voice recognition, navigation searches, and media. The navigation interface is simplified, as well. The Escalade, CTS, and XTS can now be ordered with a 360-degree camera system to display on the screen. Cadillac Enhances Phone Integration for 2016 Models with Apple CarPlay, CUE Upgrades APPLE CARPLAY AVAILABLE AT LAUNCH; ANDROID AUTO COMING LATER IN MODEL YEAR 2015-06-09 NEW YORK – Cadillac's 2016 model year products will feature enhanced connectivity and control, including the addition of Apple CarPlay and Android Auto, the predominant new systems for in-car phone integration. These additions are part of a broader enhancement of CUE, Cadillac's user experience, with new features and a faster, streamlined operation. Apple CarPlay will debut in 2016 Cadillac models featuring CUE's 8-in multi-touch screen except the SRX Crossover, a model that will move to an all-new generation in early 2016. Android Auto is expected to be phased into 2016 production at a later date. The 2016 model year will begin this summer.
