Junkyard Gem: 1973 GMC Sierra Grande Camper Special

Starting in the 1973 model year, General Motors introduced the "Rounded Line" family of C/K-series Chevrolet and GMC trucks, and sales of the pickup versions continued all the way through 1987. Nice examples of these trucks can sell for large money, but the junkyard teaches us that not all collectible vehicles are worth rescuing and fixing up. Here's a reinforcement of that lesson, courtesy of a first-year GMC C2500 Camper Special with the high-zoot Sierra Grande trim level, found in a self-service yard just outside of Denver, Colorado. I'm no GM truck expert, but I know enough to stay clear of the battles over what to call this pickup. Let's just say it's a three-quarter-ton, rear-wheel-drive third-gen C-Series with really cool badges. Yes, I bought this badge for my garage wall, and it was totally worth the $4.23. GM came up with the Camper Special package during the late 1960s, when removable pickup campers became popular, and for 1973 it included heavy-duty springs and a wiring harness made to plug into the connectors on slide-in truck campers. It also included woodsy-looking badges, but someone pried the ones off this truck before I could buy them. This may well have been a one-owner truck, because it still had original warranty paperwork inside. Here we see that it was purchased new on August 2, 1973 (which happens to be the day that George Brett got his very first hit in the big leagues) by a resident of Compton, California. Yes, that Compton. The build tag tells us that this Camper Special was born at the Fremont Assembly plant in California, which became the GM-Toyota NUMMI venture in 1984 and is now the Tesla Factory. I think most 1973 C/K pickups sold new in Colorado would have come from Pontiac Assembly in Michigan. There was a time, not many years ago, when a genuine 454-cubic-inch (that's 7.4 liters to those of you sweating under the oppressive weight of the French Empire's Measurement System) big-block Chevrolet engine would have been yanked out and purchased within hours of hitting the rows of a yard like this. These days, engine-swappers can get more power with less weight from any number of donor vehicles. If this engine is the original 454, it was rated at 240 horsepower and 355 pound-feet (down from 270 hp in 1972 due to emissions-related changes). This truck had a three-speed automatic transmission, like most optioned-up Detroit pickups of its era.

The biggest gas-guzzlers of 2024: 'The Meanest List' is the opposite of greenest cars

In some circles — especially some automotive circles — bigger is better. This explains the Hummer, for example. In its so-called “Meanest List” of a dozen models, the American Council for an Energy-Efficient Economy (ACEEE) makes no apologies for berating “the worst-performing mass market automobiles” sold in 2024 in the U.S. The most diminutive car on the list is a Chevy Corvette Z06. At the top of this particular heap is the Mercedes-Benz AMG G63, a gas-powered SUV that the environmental agency says was “the worst-performing vehicle of the more than 1,200 models assessed by Greener Cars and has an annual fuel cost over $4,000.” Not to mention its MSRP of around $184,000. Rank Make & Model Powertrain Green Score MSRP Estimated Annual Fuel Cost* 1 Mercedes-Benz AMG G63 Gas 20 $184,000 $4,242 2 Ram 1500 TRX 4x4 Gas 22 $98,335 $3,819 3 Ford F150 Raptor R Gas 24 $79,975 $3,777 4 Cadillac Escalade V Gas 26 $152,295 $3,388 5 Dodge Durango SRT Gas 26 $74,995 $3,332 6 Jeep Wrangler 4dr 4X4 Gas 27 $35,895 $3,260 7 Jeep Grand Wagoneer 4x4 Gas 28 $91,945 $3,058 8 Mercedes-Benz G550 Gas 28 $143,000 $3,186 9 GMC Hummer EV SUV EV 29 $98,845 $1,746 10 GMC Sierra Gas 29 $37,700 $3,069 11 Chevrolet Corvette Z06 Gas 30 $114,395 $3,169 12 Mercedes-Benz Maybach S680 Gas 30 $234,300 $3,031 *ACEEE analysis using EIA data of the annual cost of driving 15,000 miles In terms of numbers, the dirty dozen of the meanest includes seven SUVs and three trucks. Lonely at the middle of the list is the sole electric, the GMC Hummer EV, which weighs in at 9,000 pounds. The council notes that “though EVs have lower emissions than similarly sized gasoline models, the Hummer demonstrates that size and efficiency, not just fuel source, are important factors in a carÂ’s environmental impact.” ItÂ’s also worth reminding prospective buyers that the average fuel cost of a vehicle on the “Greenest List” eats up only a fifth of the fuel cost of a vehicle on the Meanest List, “showing that greener options can also be more affordable.” The ACEEE also put out a "Greener List" of efficient gasoline and hybrid cars that don't require plugging in.  By the Numbers Green Cadillac Chevrolet Dodge Ford GMC Hummer Jeep Maybach Mercedes-Benz RAM Emissions Fuel Efficiency Green Automakers Truck SUV Electric Hybrid

Next-gen GMC Sierra spied with diesel power

The next generation of GM trucks is arriving soon, and we're expecting a huge leap forward over the current lineup. The Chevy Silverado and the GMC SIerra sell extremely well, but haven't done much to move the segment forward in a long time. The Ford F-150 has an all-aluminum body and turbocharged V6 power. The Ram 1500 gained a diesel and coil spring suspension. These spy shots show that diesel may be in the cards for GM. Some quick shots and copious use of flash show what is most likely a tank for diesel exhaust fluid and a diesel particulate filter, both necessary equipment for any modern diesel. It's unclear what form factor that engine will come in, though GM has a number of engines to choose from, including the 2.8-liter inline four that's found in the Colorado and Canyon, though that may be a little light duty for the Silverado and Sierra. Other rumors surrounding the trucks suggest a move to an aluminum cab while retaining a steel bed. That seems like a reasonable move for GM, even if the company was attempting to shame Ford for its move to aluminum a few years ago. Look for more news as early as the Detroit Auto Show in January.
