GM reintroduces Tripower name in the worst way possible

The story of General Motors' use of the Tripower moniker begins way back in 1957, when Semon E. "Bunkie" Knudsen, then General Manager of GM's Pontiac division, directed his engineers to inject more performance into his brand's line of V8-powered automobiles. Fuel injection was an option, but hot rodders flocked instead to Tri-Power (marketed way back when with a hyphen), which grafted a trio of two-barrel Rochester carburetors onto a single intake manifold. A legend was born. And that legend was born of performance. At idle and when full power wasn't required, Pontiac's Tri-Power system used just the middle carburetor, which helped make the setup easier to tune. Depending on the year and model, either a vacuum system or a mechanical linkage opened up the two outer carbs, thereby switching from two barrels to six, and allowing the engine to take in more fuel and air. And it was an easy marketing win – six barrels is better than four barrels, right? Because performance! So, when news filtered in that GM has resurrected the Tripower name, those of us who grew up attending classic car shows and wrenching on old Pontiacs did a double-take. And then we all collectively sighed. Turns out that today's Tripower refers to a trio of fuel-saving measures that include cylinder deactivation, active thermal management, and intake valve lift control, according to Automotive News. And, at least for now, it applies to GM's line of fullsize trucks powered by a 2.7-liter turbocharged four-cylinder engine. We're all for saving fuel whenever possible. And we have zero say in how any automaker chooses to market its products and technologies. But, we'll offer our two cents anyway: Relaunching a storied name from the past is fine. Relaunching a storied name from the past while completely overlooking the reasons the name got famous in the first place is only going to irritate the people who remember the name in the first place. Couldn't they just call this new technology package something else?

Junkyard Gem: 2002 Pontiac Aztek

The General's Pontiac Division sold the Aztek for the 2001 through 2005 model years, and — despite enjoying something of a cultural rebirth in recent years — it is generally considered to be one of the worst cars of all time. The idea of using a minivan platform as the basis for a rough-and-tough-looking crossover with plenty of outdoor-lifestyle amenities wasn't the problem, since many vehicle manufacturers have printed bales of money using that formula. What doomed the Aztek was its hideous appearance and sticker price too lofty for its underemployed-at-the-time Generation X target demographic. Still, the Aztek proved to be perfectly suited for the outdoor activities that Coloradans love: hiking, camping, fishing, skiing, hauling mud-caked golden retrievers around, etc., and so you'll still find lots of Azteks on the roads of the Centennial State. Here's an Aztek Yellow Aztek (yes, that's really the paint color's official title) residing just a few rows from a '76 Checker Taxicab in a Denver self-service yard. Sure, it does look like a vehicle built to the specifications of a six-year-old who decreed a mashup between a Datsun F-10 and a Fisher-Price Little People Travel Together Airplane, but so what? There's a built-in air compressor to blow up your inflatable rafts and volleyballs, a tent attachment that turns the rear of the van into a camper, 12-volt power plugs all over the vehicle (years before this became commonplace on ordinary minivans and SUVs), and running-gear commonality with a jillion Ventures, Silhouettes, Montanas and Trans Sports. Buick managed to de-uglify the Aztek (somewhat) and sold it as the Rendezvous through 2007, but the Aztek never could win over many people with this face. I see plenty of Azteks and Rendezvouses in Denver-area wrecking yards, and I've documented a handful over the years. This one came fully loaded from the factory, with the Corvette-style heads-up display in full effect. The center console was a removable cooler, which was a great idea Â… except for the fact that this cooler holds five standard 12-ounce cans. Michigan residents tell me that this must have been intentional on the part of the Detroit-based Aztek designers, because Michiganders are expected to chug one beer out of a sixer as they walk from the liquor store to the car in the parking lot Â… which makes me extra cautious whenever I'm driving in the Wolverine State.

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).
