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.

Best and Worst GM Cars

Oh yes, because we just love receiving angry letters from devoted Pontiac Grand Am enthusiasts, we have decided to go there. Based on a heated group Slack conversation, the topic came up about the best and worst GM cars. First of all time, and then those currently on sale, and then just mostly a rambling discussion of Oldsmobiles our parents and grandparents owned (or engineered). Eventually, three of us made the video above. Like it? Maybe we can make more. Many awesome GM cars are definitely going unmentioned here, so please let us know your bests and worsts in the comments below. Mostly, it's important to note that this post largely exists as a vehicle for delivering the above video that dives far deeper into GM's greatest hits and biggest flops, specifically those from the 1980s and 1990s. What you'll find below is a collection of our editors identifying a best current and best-of-all-time choice, plus a worst current and worst-of-all-time choice. Comprehensive it is not, but again, comments. -Senior Editor James Riswick Best Current GM Vehicle Chevrolet Corvette We were flying by the seats of our pants a bit in this first outing and my notes were similarly extemporaneous. When it came time to tie it all together on camera, I failed spectacularly. Thank the maker for text, because this gives me the opportunity to perhaps slightly better explain my convoluted reasoning. I chose the C8 Corvette because it's simply overwhelmingly good, and it's merely the baseline from which this generation of Corvette will be expanded.  While the Cadillac CT5-V Blackwing (more on that in a minute) is an amazing snapshot of GM's current performance standing and its little sibling so enraptured me that I went out and bought one, their existence is fleeting. Corvette will live on; forced-induction Cadillac sport sedans, not so much. So while all three are amazing machines when viewed in a vacuum, the Corvette stands above them as both a reflection of GM's current performance credentials and a signpost of what is to come. So, given the choice between the C8 and the 5V-Blackwing right now, I'd choose the C8. In 10 years, when the Blackwing is no longer in production and Corvette is in its 9th generation? Well, that might be a different story. Now, just pretend I said something even remotely that coherent when we get to the part of the video where I try to make an argument for the 5-V Blackwing as best GM car I've ever driven. Or just laugh at me while I ramble incoherently.

GMC moved the headlights down on the 2024 Sierra EV to prevent glare

There are a lot of things that are different between the 2024 GMC Sierra EV’s design and the gasoline Sierra pickup, but one we noticed right away was the headlight placement. On GMÂ’s full-size gasoline trucks, the headlights are about as far up the front fascia as they can be. In the Sierra EV, theyÂ’re positioned significantly further down and into the lower bumper below the grille. Why are we highlighting this particular aspect of the design? Well, unless you only ever drive massive, high-riding trucks, youÂ’re probably very accustomed to being frequently blinded by them on the road these days. In describing the Sierra EVÂ’s headlight placement, designers told us they intentionally put the lights further down to improve matters. We pulled Phil Kucera, a GMC design manager, aside to ask him about the change. “It tends to be a better spot where itÂ’s not glaring in other peopleÂ’s eyes, right, the lower you get,” Kucera says. Beyond blinding others, putting the headlights lower on the face of the truck improves headlight performance for the driver, too. “Typically the lower the better, because thatÂ’s where theyÂ’re going to be on the road, so thereÂ’s less to reflect off of in fog or rain,” Kucera explained. “If you get them up at a certain height, theyÂ’re going to be reflecting certain things like snow, rain or things like that in your eyes.” 2024 GMC Sierra EV Denali Edition 1 View 13 Photos Of course, youÂ’ll notice on the Sierra EV that the daytime running lights (DRLs) are still big and bold in the upper part of the front end. These lights are around for decor, though, and act as pieces of design rather than a functional way to see at night. In other words, theyÂ’re lights, but theyÂ’re not going to dazzle oncoming traffic or cause glare for the driver like a headlight pointed down the road will.  Moving those lights further down in the front should hopefully be a net positive for other drivers coming across the Sierra EV and for drivers of the truck themselves. How the lights are aimed plays just as much a role in how other drivers perceive oncoming lights, though, so weÂ’ll have to wait and see the real-world performance on this one.  WeÂ’ll also note that moving the actual headlights further down the front end doesnÂ’t take anything away from the design of the Sierra EV. It still features a strong, upright stance that the world is accustomed to seeing from new trucks these days. ItÂ’s no surprise, but GM agrees.
