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: 1991 Pontiac Grand Am LE with Quad 4 Engine

GM introduced the N-Body compact platform with the Oldsmobile Calais and Pontiac Grand Am for the 1985 model year and continued building N-based cars through 1998. Most of these cars weren't interesting from an enthusiast standpoint, but a handful rolled off the assembly line with raucous DOHC Oldsmobile Quad 4 engines and manual transmissions, and those cars were plenty of fun. Here's a 1991 Grand Am with that rare setup, photographed in a self-service yard in California's Central Valley. The base engine in the 1991 Grand Am was the 110-horsepower, 2.5-liter pushrod Iron Duke, an engine that might have been fine on a Romanian tractor in 1953 but had no place on an American street car as the 21st century approached. Fortunately, GM started bolting the modern 2.3-liter DOHC Quad 4 engine into 1988 cars, and this was a proper four-cylinder. The Quad 4 ran a little rough and uncivilized, and it had its share of reliability problems, but you could rev the piss out of it and it made good power. In 1991, this engine was rated at 180 hp. That made this 2,592-pound sedan pretty quick. Unfortunately, the slushboxization of America had progressed with depressing rapidity during the 1980s, and by 1991 most Grand Am buyers — even the ones who opted for the Quad 4 — chose the automatic transmission. That didn't happen with this car, though — it boasts a rugged Getrag 5-speed instead of the happiness-amputating three-speed automatic. Yes, that's the kind of odometer reading you'd expect to see on an Accord or Maxima from this era. Someone loved this car and took care of it. Here we see an interesting mix of 1980s and 1990s car-radio technology. CD players in cars were still costly luxury items in 1991, seldom seen in affordable cars like the Grand Am, while 1980s-style slider-style EQ controls were on the way out. This Delco unit straddles both decades nicely. I seek out Quad 4-equipped cars during my junkyard travels, and I have photographed quite a few: this '89 Cutlass Calais, this '90 Cutlass Calais, this '90 Grand Am, this '91 Quad 442, this '93 Achieva SCX, and this '98 Cavalier Z24. It's a shame that Buick never put the Quad 4 in the Reatta, which was a fine car ruined by a somnolent and obsolete V6. The music in this ad is even more early-1990s than Crystal Pepsi.

Junkyard Gem: 1986 Pontiac Fiero 2M4

The mid-engined, plastic-bodied Pontiac Fiero two-seater caused great excitement when it hit the streets as a 1984 model, then became something of an embarrassment for GM when its design flaws became clear to the car-buying public. Still, when a V6 engine became available for 1985, followed by a fastback roof for 1986, the air of Pontiac Excitement around the Fiero lingered to a certain extent. We took a look at a discarded '86 Fiero GT with both the 2.8-liter V6 and the fastback body last year, and now we'll take a look at an example of the econo-commuter four-cylinder notchback version from the same year. Pontiac used the 2M4 designation (standing for two seats, mid-engine, four cylinders) on four-cylinder Fieros, while the six-cylinder cars were known as 2M6s. 2M4 decals went on four-banger Fieros for the 1984-1986 model years, while 2M6 decals seem to have been applied less consistently to the V6 cars of that period. During the early development period of the car that became the Fiero, the idea was that it would be a nimble sports car with a lightweight engine. Then the plan shifted, with the Fiero intended to be a gas-sipping commuter. When the car finally hit showrooms, it was a lot heavier than intended, it had a Chevy Citation front suspension in the back plus a Chevette front suspension, and its engine was the low-revving, weighty Iron Duke 2.5-liter straight-four. The Duke was about the least sports-car-appropriate four-cylinder engine The General could dredge up from his parts bins, but it was cheap and there was no shortage of production capacity. By the time the Fiero came out, the Iron Duke had been renamed the Tech 4. This one was rated at 92 horsepower and 132 pound-feet. The V6 Fieros get all the press today, but plenty of the Duked versions were sold (amazingly, the Chevrolet Camaro was available with Iron Duke power from 1982 through 1986). The emissions sticker tells us that this was a California-market car, rather than the "49-state" model the rest of the country got. California-specific emissions hardware added $99 to this car's price ($277 in 2023 dollars). While this car is a base model, the original buyer loaded it with options. The transmission is a three-speed automatic, priced at $465 (about $1,303 in 2023 dollars). A five-speed manual was standard equipment on the 1986 Fiero, though the old-fashioned four-speed manual was still available for a $50 credit ($140 now).
