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: 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.

Pontiac Firebird in latest Generation Gap scrap

Generation Gap is mining the Lingenfelter collection again this week to compare two very different interpretations of the Pontiac Firebird. An original 1968 example goes toe-to-toe with a 2010 Lingenfelter Trans Am to see whether the old man or the modern re-imagining takes the crown.
Being from the Lingenfelter collection, both cars are absolutely immaculate. The '68 packs a Pontiac 350-cubic-inch (5.7-liter) V8 with a claimed 320 horsepower and some classic, muscular style with a hood-mounted tach. Plus, it's painted in an understated shade of green that you don't usually see.
In the other corner is Lingenfelter's pumped-up take on the classic shape based on the modern Camaro, and this is just one of six concept versions ever made. It wears an eye-catching, vintage-inspired livery of blue with a white stripe package. Under its shaker hood is a 455-cubic-inch (7.5-liter) V8 with a reported 655 hp and 610 pound-feet of torque.
