GM reportedly developing 2.5-liter turbo four-cylinder

General Motors is allocating a massive amount of resources to developing electric technology, but it's not forgetting about the gasoline-powered cars that make up the bulk of its sales. It's reportedly designing a new 2.5-liter turbocharged four-cylinder engine based on its 2.7. Citing "sources familiar with the matter," enthusiast website GM Authority wrote that the 2.5-liter four is "in [the] final stages of development," meaning it should be announced sooner rather than later (assuming the report is accurate). Technical details are few and far between as of writing. The publication learned that the 2.5 will be part of the Cylinder Set Strategy (CSS) family of engines and that it will be mechanically related to the 2.7-liter currently found in the Chevrolet Silverado 1500, among several other models. It will feature dual overhead camshafts. It's too early to tell which models the 2.5-liter four-cylinder will end up in, or how much power it will generate. The output will likely depend on the application. For context, the 2.7 delivers 310 horsepower at 5,600 rpm and 348 pound-feet of torque between 1,500 and 4,000 rpm in the Silverado. In the smaller Colorado, it provides anywhere between 237 and 310 horsepower depending on the trim level selected. While this is pure speculation, our crystal ball tells us the engine will end up powering crossovers. It's an easy deduction to make. We can't imagine it will be offered in the Silverado, and seeing it in the Colorado is unlikely because its entry-level engine develops 237 horsepower; there's likely not much of a market for a midsize truck with 200 or so horsepower. Putting it in the Corvette wouldn't make sense and the Camaro has nearly reached the end of its life cycle without a successor planned. This leaves us with Chevrolet's range of crossovers, like the Equinox, as well as their GMC-, Buick-, and Cadillac-branded counterparts. We're not discounting the possibility that the cars set to receive the 2.5 haven't been unveiled, but those are likely crossovers, too; the odds of seeing another big Chevy sedan are very, very low. General Motors hasn't commented on the report, and it hasn't publicly announced plans to expand its CSS family of engines. If the report is accurate, we should learn more about the new turbocharged, 2.5-liter four-cylinder engine in the not-too-distant future.

Buick reveals wild GL8 minivan concept and Smart Pod concept in China

Buick, being the hit in China that it is, decided to unveil a couple of concept vehicles at the Guangzhou Auto Show. One is the GL8 Flagship Concept, and the other is the Smart Pod Concept. Since an actual minivan is far more interesting than any “Smart Pod,” weÂ’ll start with the GL8 Flagship Concept. The exterior is meant to be luxurious and “dynamic” looking with its mix of colors, glass canopy roof, wing-shaped headlights and highly-sculpted body. ThereÂ’s hardly a piece on the car that isnÂ’t making a statement, and the highlights continue when you open the doors. It becomes fairly clear right away that this minivan is not one for family use, as itÂ’s only rocking four seats. That said, everybody in those four seats is guaranteed to be comfortable. Buick says itÂ’s using “zero gravity” lounge seats inside, and the cabin as a whole is inspired by Chinese mountain and water landscapes. That could explain the multi-color floor, as the blue section looks like it could be the water at the base of a mountain, surrounded by a beach. Features include a tea tray, 30-inch driver display, touchscreen on the steering wheel, full windshield-width head-up display and a new audio system that features speakers in the headrests. Buick says all of the carÂ’s functions can be controlled by voice, too. Beyond the obviously futuristic touches, this Buick minivan is just plain gorgeous. Its gold, blue and cream color combo and various materials used throughout look like top-notch luxury. WeÂ’d love to see some of this attention to detail and luxury trickle down into some of BuickÂ’s production cars. Smart Pod Concept Buick Smart Pod Concept View 17 Photos Unlike the GL8, the Smart Pod was designed in the U.S. It uses the electric Ultium platform and what Buick is calling the VIP electric architecture. The exterior design is basically what Buick has called it — a pod. Its lights use micro-LED tech to make them as sleek as possible. On the inside, Buick designed the Pod to be as spacious and airy as can be. It has a glass roof, a fully reclining and dedicated sleep seat and a modular seating layout. Other features include deployable tables, noise-cancelation  tech, an air purifying system and a 50-inch LED screen. It is powered by an AI assistant that employs voice commands, eye-tracking technology, integration with your mobile devices and machine learning to adapt to the user.

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.
