2023 Grand National Roadster Show Mega Photo Gallery | Hot rod heaven

POMONA, Calif. — From an outsider's perspective, it would be easy to assume that the Grand National Roadster Show has always been a Southern California institution. After all, it celebrates the diverse postwar car culture of the region — hot rods, lead sleds, lowriders, and more. However, the show had its roots in NorCal in 1950 when Al Slonaker and his hot rod club showed their custom cars at the Oakland Expo. The GNRS moved to Pomona, California, in 2004. By then it had grown exponentially and seen about a dozen more car customization trends come and go. However, the show and its centerpiece award, the America's Most Beautiful Roadster prize, celebrate what is perhaps the first of those trends: the American hot rod in its purest form. Today, in its 73rd year, the GNRS is the oldest indoor car show in America. Annually it welcomes 500-800 cars, gathered into special themes like Tri-Five Chevys or Volkswagen Bugs. At this year's show, which was last weekend, a special hall was dedicated to pickup trucks built between 1948-98, including mini-trucks, groovy camper bed conversions, and resto-mods.  However, of all the vehicles presented, only nine are eligible for the America's Most Beautiful Roadster award. Winners get their names engraved on a 9-foot-tall perpetual trophy that was, according to The Ultimate Hot Rod Dictionary, the largest in the world when it debuted in 1950. Slonaker chose the word "roadster" initially because "hot rod" bore slightly negative outlaw connotations in 1950. Only American cars built before 1937 of certain body styles — roadsters, roadster pickups, phaetons, touring cars — are eligible, and they cannot have roll-down side windows.  Cars in the running for the cup cannot have been shown anywhere else before their debut at the GNRS.  Contestants for this accolade essentially build their cars to the a platonic ideal of a hot rod. This year the honors went to Jack Chisenhall of San Antonio, Texas, for his "Champ Deuce," a 1932 Ford Roadster. It's exactly what you picture when you think of a hot rod, but distilled to its absolute essence.  Other standouts included "Green Eyes," a two-tone green 1959 Chevy El Camino  with a heavily metal-flaked bed, "Blue Monday," a 1964 Buick Riviera lowrider, and a personal favorite, "Purple Reign," a purple and black 1951 Mercury. Cars may have started out as tools, but there aren't shows like this filled with custom refrigerators.

Junkyard Gem: 2003 Pontiac Grand Am GT 30th Anniversary Edition

With the era of the 1960s-style muscle car ended by the ever-more-stringent emissions regulations, insurance costs and higher gasoline prices of the early 1970s, GM's Pontiac Division was ready with a lineup of flash-enhanced machines packed with (alleged) European-style performance and styling. Three of them were based on the midsize A Platform for 1973: the LeMans, the Grand Prix and the brand-new Grand Am. The 1973 Grand Am was cheaper than the luxed-up Grand Prix, but still had a BMW-ish interior and wild exterior styling; sales weren't great, but the 30th anniversary of this car seemed sufficiently momentous for Pontiac to create a special-edition package for its soon-to-be-axed successor. Here's one of these rare machines, spotted recently in a Denver car graveyard. The original rear-wheel-drive Grand Am was built for the 1973-1975 and 1978-1980 model years, but its similarity to the much cheaper LeMans kept sales numbers unimpressive. When the Grand Am name was revived for a Pontiac-badged compact on the front-drive N Platform in the 1985 model year, however, it became a big seller right away and stayed that way into our current century. The N-Body Grand Am was built through 2005, with platform updates for the 1992 and 1999 model years. Along the way, it was sibling to such cars as the Oldsmobile Calais, Buick Somerset, Chevrolet Beretta and Oldsmobile Alero. By 2003, though, the ground was shifting under Pontiac's feet. The iconic Firebird had been discontinued the previous year, and even the Grand Prix's days were officially numbered. Oldsmobile would be gone after 2004, and the entire Pontiac vehicle lineup would be shaken up soon after. The last year for the Grand Am (and the Sunfire) would be 2005, with the G6 taking its place. With all that going on, why not offer a 30th Anniversary package? After all, the Grand Prix got a 40th Anniversary Edition for 2002. Our reviewer described this car as "leaner, trimmer and more contemporary" at the time, but made no mention of the 30th Anniversary Edition. The VIN says this car is a top-grade GT1 sedan, with an MSRP of $22,325 (that's about $39,920 in 2023 dollars). Two engines were available in the 2003 Grand Am: a 2.2-liter Ecotec four-cylinder with 140 horsepower and a 3.4-liter pushrod V6 with either 170 or 175 horsepower. This car has the 175-horse V6, complete with "Ram Air" cold-air induction. That name goes way back in Pontiac history.

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?
