GM's Ultium EV platform finally shows up in Q3 sales numbers

General Motors has heralded its Ultium battery-electric platform as the future of its passenger car and truck lineup, but for the first two years of its existence, its impact on the marketplace has been virtually nonexistent. Well, that finally changed in the third quarter of 2023, and while the cars based on this architecture don't represent anywhere near the volume of GM's broader combustion portfolio, we're reaching a point where Ultium products are finally in view (and in the hands) of real-world shoppers. At this point, five U.S.-market Ultium models are in production: the GMC Hummer EV, Cadillac Lyriq, Chevrolet Blazer & Silverado EV, and BrightDrop Zevo 600. If you're not familiar with that last one, that's OK; it's a commercial product that you likely won't see on the road for some time. Together, these four combined for 4,257 sales in the third quarter alone — up from 2,663 for the entire first half of the year. While that may not seem like a significant uptick when viewed from altitude, the quarter-to-quarter numbers paint a clearer picture.  Let's toss out the stragglers first. The Chevy Blazer EV, and Silverado EV for example, are barely in production. GM delivered 19 Blazers and 18 Silverados in the third quarter and that's the entirety of their production runs so far. Likewise, GM's BrightDrop Zevo 600 delivery van effectively exists apart from the consumer marketplace, so its contribution of just 35 units can be set aside too. That leaves us the two you've heard of: the GMC Hummer EV and Cadillac Lyriq — models with high sticker prices and long reservation queues.  Through the second quarter (remember, we're talking six months here), GMC sold 49 Hummer EVs. No typo. In the three months that made up the third quarter, GM moved 1,167 of them. Not only is that a dramatic improvement over the first half, but it's more Hummers than GMC sold in the entirety of 2022 (854). Lyriq's improvement was less eye-popping on paper, but after moving just 122 total units in 2022 and 2,013 of them in the first half of 2023, Cadillac managed to up that figure to 3,018 units in the third quarter alone.  GM is betting its short-term EV future on the Ultium platform, so these trends need to continue if that's going to be a profitable wager.

GM recalls 3.8 million vehicles in North America due to braking issue

WASHINGTON — General Motors Co said Wednesday it was recalling 3.46 million U.S. pickup trucks and SUVs to address a vacuum pump issue that could make braking more difficult and that has been linked to 113 accidents and 13 injuries. The recall covers 2014-2018 model year vehicles, including some Cadillac Escalade, Chevrolet Silverado, Chevrolet Tahoe, GMC Sierra, Chevrolet Suburban and GMC Yukon vehicles. In late June, GM recalled 310,000 vehicles in Canada for the same issue. GM did not immediately explain why the Canadian recall occurred more than two months before it called back the vehicles in the United States. The recall was triggered because the amount of vacuum created by the vacuum pump may decrease over time, GM told the National Highway Traffic Safety Administration (NHTSA) in documents posted on Wednesday. The NHTSA opened a preliminary investigation into the issue last November, and said it had reports of nine related crashes and two injuries. It provided GM in July with additional field reports that prompted the automaker to open an investigation. GM said it could affect braking in "rare circumstances." The NHTSA said in a statement the "vehicles may experience brake boost failure, which would require increased brake pedal effort, leading to a hard brake pedal feel, and potentially increased stopping distance." GM said dealers will reprogram the electronic brake control module to improve how the system utilizes the hydraulic brake boost assist function when vacuum assist is depleted. GM said the vacuum assist pump, which is lubricated with engine oil that flows into the pump through a filter screen, can in some cases lose effectiveness over time, as debris such as oil sludge can accumulate on the filter screen. GM told NHTSA that prior model years used a different brake assist system design, and vehicles manufactured after 2018 were not equipped with the affected pump design. Separately, GM said on Wednesday it is recalling 270,000 additional U.S. vehicles in three smaller recalls, including 177,000 2018 Chevrolet Malibu cars with 1.5L turbo engines because an error in the engine control module software may result in the fuel injectors being disabled.

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.
