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.

Junkyard Gem: 1986 Buick Riviera

The Buick Riviera personal luxury coupe attained monstrous proportions by the middle 1970s, scaling in at well over 4,500 pounds by 1976. After spending 1977 and 1978 as sibling to the Chevy Caprice, the Riviera then moved to the front-wheel-drive platform used by the Cadillac Eldorado and Oldsmobile Toronado, staying there through the 1985 model year. The Riviera world became a lot more interesting for the 1986 model year, when a smaller and more sophisticated generation hit showrooms with curvier lines and electronic gadgetry straight out of science fiction. Today's Junkyard Gem is one of those cars, found in a self-service boneyard in Phoenix, Arizona. What makes this car such a fascinating bit of automotive history is this dash-mounted touchscreen interface, known as the Graphic Control Center. The 1986 Riviera was the first GM vehicle to get the GCC, which means it was the first production car in history with a factory-installed touchscreen display. This system became available in the Buick Reatta and the Oldsmobile Toronado a few years later.  The GCC used a cathode-ray tube screen sourced from an ATM manufacturer, which ran on 120VAC power and required an inverter and dangerous high-voltage wiring inside the dash. It was used to operate the HVAC, the radio and the trip computer, as well as to display operating and diagnostic information. The system used numerous bulky components in addition to the dash screen; I've extracted a couple of complete sets of GCC components over the years and plan to build them into a junkyard-parts boombox. As it turned out, the senior-citizen-heavy demographic of Buick shoppers didn't feel great enthusiasm for the GCC and there wasn't a huge sales payoff for this revolutionary technology. That didn't stop GM from introducing the first mass-produced cars with head-up displays a couple of years later. The running gear wasn't quite as sophisticated as the GCC. The 1986-1993 Rivieras got old-fashioned 3.8-liter Buick V6s under their hoods; the one in this car was rated at 140 horsepower and 200 pound-feet. If you wanted a manual transmission in your '86 Rivvie, you were out of luck. A four-speed automatic was mandatory equipment. Note the unusual face-loading cassette deck in front of the shifter; the AM/FM radio was a remote-controlled unit living inside the center console. The MSRP for this car was $19,831, or about $55,691 in 2023 dollars.

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.
