2023 GM full-size SUVs get Super Cruise expansion pack first

In August, GM announced it had doubled the size of the network of roads available to its Super Cruise hands-free driving feature. Joining the options list in 2017, Super Cruise had been limited to divided interstate highways in the U.S. and Canada. The expansion opened 200,000 miles of additional divided interstate highway as well as major, undivided highways. Both coasts benefit, but there will be a lot more relaxing motoring on the East Coast especially. North of the border, six of the 10 Canadian provinces add enabled roads. Problem is, no GM vehicles have been able to take advantage of the boon. That changes this month, the automaker saying four of its full-size SUVs in specific trims are first in line to make use of the expansion. The SUVs are: 2023 Chevrolet Tahoe Premier and High Country 2023 Chevrolet Suburban Premier and High Country 2023 Cadillac Escalade, Escalade ESV, and Escalade-V 2023 GMC Yukon Denali Ultimate  The vehicles need to have been built on or after October 3, 2022, a production timeline GM says should put the first examples in customer hands this month. The least expensive way to get into Super Cruise is with the two-wheel drive, $77,625 Chevrolet Tahoe Premier with the 3.0-liter inline-six Duramax diesel and the Advanced Technology Package. Vehicles that use the GM's Vehicle Intelligence Platform electrical architecture and already have Super Cruise will receive an over-the-air update "in the coming months" to access the new roads, at no cost to owners. Since other products like the Cadillac CT4 and CT5, Chevrolet Silverado, and GMC Sierra work with the VIP platform as well, they probably aren't far away from the extra capability and they'll bring a lower financial bar to entry.  Related video:

Cadillac CT5 Luggage Test | How big is the trunk?

The Cadillac CT5 is a midsize luxury sedan. At least by today's standards. By the standards of Cadillac's past, it's practically a compact. At 193.8 inches long, the CT5 is 3 inches shorter than its STS predecessor of 15 years ago and 11 inches shorter than the Seville of 25 years ago. This is significant since virtually every other car brand's offerings have grown from generation-to-generation. See the BMW 5 Series as just one example. You'd have to go back to the 1980s to find a CT5 ancestor that's smaller, though that stubby thing was an aberration.   Honestly, I'm just sharing that because I think it's interesting. This post is about trunk space, and exterior size doesn't necessarily equate to how much junk you can fit in the trunk. In fact, the CT5 is pretty good example of that. Although smaller than its predecessors, the CT5 is still an awfully big car that's comparable to other midsize luxury sedans, including the 5 Series, Audi A6 and Mercedes-Benz E-Class. The trunk, however, is notably smaller than what you'd get in those with a rather rinky-dink 11.9 cubic feet. That's coupe territory and less than what you'd get in some subcompact sedans. The A6 and E-Class are in the 13-cube range, while the 5 Series apparently has 14.5 cubic feet.  So, how small is 11.9 cubic feet? Although plenty wide at the rear, which should be handy for golf clubs, the CT5's trunk isn't very long compared to all those competitors. The A6's is narrower but also practically a tunnel by comparison. Also, note the ramp-like structures along the outer edges. Besides making loading a hassle, they effectively make the trunk even smaller than the 11.4 cubic-feet that's technically there since it's so difficult to load items right up to the wheel wells. You can see a closer look at those "ramps" above left along with the smallish pass through that oddly looks like a previous-generation Hyundai Sonata's grille.  Above right you can see the underfloor storage. There is no spare tire.  Besides those "ramps" impeding luggage loading from below, these giant speakers hanging down from the parcel shelf sure don't help, either. Watch your hands while loading, as well as anything that might be easily scratched (or that might damage the speakers) OK, let's get to the bags.

GM executive chief EV engineer says reducing cost of plug-in vehicles is 'huge priority'

As we know, another major automaker investing heavily in electrified vehicles is General Motors, and it's doing things much differently than rivals BMW, Ford or Nissan. The Chevrolet Volt extended-range EV is a modest seller at its $35,000 sticker price but a huge hit with owners. The Chevy Spark BEV, still in limited availability, puts smiley faces on its owners and drivers. The just-introduced Cadillac ELR, a sharp-looking, fun-driving $76,000 luxocoupe take on the Volt's EREV mechanicals, has admittedly low sales expectations. With this interesting trio in showrooms and much more in the works, the third vehicle electrification leader I collared for an interview at Detroit's North American International Auto Show (see #1 and #2) was Pam Fletcher, GM's executive chief engineer, Electrified Vehicles. ABG: Why do your EREVs need four-cylinder power to extend their range when BMW's i3 makes do with an optional 650 cc two-banger? "We designed [the Volt and the ELR] to go anywhere, any time" - Pam Fletcher PF: I get that question all the time: why not something smaller? You don't really need that much. You use the electric to its ability, then you just need to limp. But we designed those cars to go anywhere, any time, and we don't want their performance to be compromised. If you're driving through the mountains, we don't want you to be crawling up grades, or to be limited on any terrain. So it's optimized to be able to travel literally the biggest grades and mountain roads around the globe at posted speeds. Because what if you can't? Another good reason: when the engine is on, you have to run it wide open throttle, max speed, most of the time. And while we can do a lot with acoustics, and the ELR has active noise cancelation, a small-displacement, low cylinder-count engine at high speed, high load all the time isn't something you want to live with. That's how we came up with the balance we did among the key factors of performance, NVH [noise, vibration and harshness] and range. ABG: Where you go from here? Is the range-extender engine due for an update? PF: We know and love the current Volt, and there is still a lot of acclaim about it, so we think it's a good recipe. But we are heavily in the midst of engineering the next-generation car, which I think everyone will love and be excited about.
