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.

Junkyard Gem: 1957 Buick Special Riviera Sedan

While I find plenty of 1950s Detroit cars in quick-inventory-turnover self-service wrecking yards during my travels, they tend to be the ordinary post sedans that were built by the millions during the heyday of the three-on-the-tree manual transmission and nuclear-attack symbols on car radios. The more sought-after convertibles, coupes, and four-door hardtops are tougher to find in such yards, which makes today's 1957 Buick Special Riviera in a yard in northeastern Colorado an A-List Junkyard Gem. During the late 1950s, the Special ranked at the bottom of the Buick prestige hierarchy just below the more upscale Super and Century. Of course, this was the era of Alfred Sloan's "Ladder of Success" and the lowliest Special outranked even the nicest Olds Ninety-Eight on the Swank-O-Meter. If you were the Buick-driving Joneses and your neighbors had proletarian Chevrolets, aspirational Pontiacs, or petit-bourgeois Oldsmobiles, they were failing to keep up with you… but then you'd see a new Cadillac and feel intense envy for your victorious rival. The Ladder of Success collapsed later on, when the top-trim-level Chevy Caprices began to compete against their Cadillac Calais big brother, but it was still standing tall in 1957. The Riviera name ended up being used for its own distinct model starting in 1963 and continuing nearly into our current century, but in 1957 it was a trim level designation, used to indicate a Century or Special sedan with the then-radical pillarless hardtop design. This car listed at $2,780, which comes to a cool $27,630 in 2021 dollars. That price included the 364-cubic-inch (6.0-liter) Buick Nailhead V8 engine, rated at 250 horsepower and enough torque to peel 1957's rock-hard bias-ply tires right off their rims. The Special had a three-on-the-tree column-shift manual as standard equipment, but the original buyer of this car sprang for the extra $220 ($2,185 today) to get the Dynaflow transmission. While the shift indicator looks just like the ones on GM cars equipped with the two-speed Powerglide, the Dynaflow was an odd beast used only in Buicks; while it had gears for two forward speeds, the driver had to select low gear manually. Otherwise, a complex torque converter rig provided an experience something like today's CVTs (though with better smoothness and much more wasted power), in which the car stayed in high gear all the time and used the torque converter to multiply as needed.

Junkyard Gem: 1982 Buick Riviera Diesel Coupe

After appending the Riviera name to various cars during the 1950s, Buick finally made the Riviera a model in its own right for the 1963 model year. Seven more generations of Buick's rakish personal luxury coupe followed over the next 36 years, but only one ever had an oil-burning engine available from the factory. Today's Junkyard Gem is one of those cars, a vividly purple '82 Riviera with 105 horses of Oldsmobile diesel power under its hood, found in a Denver-area self-service boneyard recently. Starting in the 1966 model year, the Riviera had been living on the same platform as the Cadillac Eldorado and Oldsmobile Toronado, both of which featured radical front-wheel-drive powertrains that used longitudinal V8s powering the front wheels via sturdy chains. However, despite the common platform, the Riviera alone kept the then-traditional front-engine/rear-drive setup, making it something of a corporate oddball for the next 12 years. Then General Motors decided to downsize the Eldorado/Toronado platform for the 1979 model year, and the Riviera got those cars' front-wheel-drive rig at the same time. Sales of the smaller Rivvy were strong, no doubt due in large part to certain geopolitical events that sent gas prices skyward and caused fuel rationing and gas lines. Back in the late 1970s and early 1980s, diesel fuel was much cheaper than gasoline in the United States. Mercedes-Benz and Peugeot had done reasonably well selling diesel-engined cars here during the 1970s, and so General Motors developed a diesel-burning version of the Oldsmobile 350-cubic-inch (5.7-liter) V8 engine. As was typical of naturally-aspirated automotive diesels of the time (every modern car's diesel engine is turbocharged), horsepower was miserable but torque was strong; the engine in this car was rated at 105 horses and 205 pound-feet. The 5.7 diesel first showed up in the Riviera for the 1981 model year. The base engine was a 4.1-liter version of the Buick V6, while the oil-burning Olds cost an extra $924 (about $3,206 in 2023 dollars). A comfortable and smooth-riding Riviera with the cheap fill-up price and long range of diesel sounded great, even if you had to line up with Freightliners and Peterbilts to get to a pump, but there were problems. Oh, so many problems! Oldsmobile's 350 V8 had been around since 1968 and it had proven to be both reliable and powerful.
