Junkyard Gem: 1990 GMC S-15 Jimmy 4x4

The General sold the GMC-badged version of the first-generation Chevy S-10 Blazer, known as the S-15 Jimmy or just the Jimmy, from the 1982 through 1994 model years. These trucks were based on the small S-10 pickup and sold well (until small trucks were forced to get bigger and less truck-like after the dawn of the Ford Explorer-inspired commuter-truck era), but they have become difficult to find in vehicle graveyards in our current century. Here's a '90 Jimmy 4x4 with red-primer paint job, found in a self-service yard on California's Central Coast last month. GMC shoppers could get the 1990 Jimmy as a rear-wheel-drive truck, but this one has the four-wheel-drive option that allowed Tahoe-bound skiers to skip the chain monkeys on the way to the slopes (the CHP, understanding that California drivers have a 95% mortality rate on snow or ice, requires chains or four-wheel-drive to get over Donner Pass when there's a hint of snow forecast). GM sold so many millions of small-block Chevrolet V8s that it made economic sense to use the same tooling to produce a V6 version. The result was this truck's 4.3-liter V6 that was three-quarters of the good old Chevy 350 (5.7-liter) V8 that powered so many Camaros, Chevelles and Impalas. The 4.3 didn't make smooth power, but it got the job done and held together quite well. This one was rated at 160 horsepower, good enough for the Jimmy 4x4's 3,512-pound curb weight. These days, though, used-truck shoppers insist on at least two tons of heft plus four doors. Some discount lot in Monterey or Salinas couldn't even get $999 for this truck, and so it ended up in the final stop before the cold steel jaws of the crusher. 1990 was the last model year for the two-door-only Jimmy; for 1991, the Jimmy came with a choice of two doors (for devil-may-care types) or four doors (for drop-the-kids-at-school types). I've always liked the look of the instrument panels on the early S-10s and its siblings; even though the designers had to work within strict budgetary limitations, they made the panels look interesting. This truck nearly made it to 170,000 miles before the end. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. So powerful with the 4.3 (the regular S-15 pickup still came with a 2.8-liter V6 as base equipment) that it could destroy a TV camera.

2019 GMC Sierra carbon fiber bed: How it's made

FORT WAYNE, Ind. — The redesigned 2019 GMC Sierra has some pretty nifty features, and the one that has had the most attention is the MultiPro flipping and folding tailgate. But the Sierra also features the first-of-its-kind carbon fiber truck bed. It's interesting, of course, for its capabilities, such as being 62 pounds lighter than the all-steel box. It even adds more cargo volume since the material can be assembled and shaped differently from steel. As it turns out, the assembly process is cool, too, which we learned when GMC invited us to see the beds being made. Every GMC carbon fiber bed starts out as perfectly flat sheets of thermoplastic carbon fiber. The sheets consist of a mix of fibers and resins, a bit like the molded carbon fiber parts Lamborghini uses. The sheets are manufactured by Japanese company Teijin, which collaborated with GMC to develop the bed. They're all delivered to Continental Structural Plastics (CSP) in Fort Wayne, Ind., for construction into the actual bed. The company, a subsidiary of Teijin, makes a wide variety of composite and plastic parts for the car industry, including body panels for the C7 Chevy Corvette. The rectangular sheets are cut to shape and stacked up at a giant stamping press. Robots pick up sheets and slide them onto a conveyor that goes into a large oven. The heat softens the parts so they can be stamped. The large primary bed parts such as the base are stamped by CSP's enormous 3,600-ton press, and the smaller ones go through a 1,000-ton press. Each press can do different parts using different stamping dies, and CSP switches between dies to produce different batches of parts. After stamping, the parts roll out mostly ready for assembly, but there are rough edges that are trimmed off by water-jet cutters. These cutting machines also create holes for fasteners and for parts such as tie-down hooks and lights. The stamping process also provides the carbon fiber bed with a unique Easter egg. On the bottom of the base of the bed, there are two words: "Connors Way." This is a tribute to Tim Connors, who was the chief engineer of manufacturing at GM and a strong proponent of the carbon fiber bed. He was tragically killed in a motorcycle crash a few years ago. The words were added to honor him, and they were fortunately approved for production. There are some components to the bed that aren't stamped from the flat sheets of material.

GMC Hummer EV pickup reveal postponed

We’re pretty excited about the all-electric Hummer pickup coming from the GMC brand. GM is too, enough to spend Super Bowl money on an ad teasing it. Today, we received an update from GM about the Hummer EV, with good news and bad news. The bad news: GM has announced that it is postponing the May 20 reveal for the Hummer. With the coronavirus throwing the proverbial wrench into a number of vehicle operations, including reveals, we canÂ’t say weÂ’re surprised at all. The good news, GM assures us, is that development continues “undeterred.” GM understandably hasnÂ’t provided a new debut date for the GMC Hummer EV, but it did provide us with the new short teaser video above. WeÂ’ve seen other details in previous teasers, as well. We were lucky enough to see the Hummer EV in person last month just before the pandemic began causing the world to grind to a halt. At GMÂ’s EV Day at its Warren, Mich., campus, the Hummer pickupÂ’s exterior was on full display. ItÂ’s a big, off-road-ready pickup complete with giant all-terrain rubber and tow hooks. It features removable roof panels for access to the open sky, which appears to be depicted in the teaser above. It features sail panels behind the C-pillars, similar to those on the Chevy Avalanche and Honda Ridgeline. Its bed was concealed with a tonneau cover, but it sported GMCÂ’s MultiPro tailgate that we first saw on the Sierra Denali. Interior photos showed a spacious interior with blocky shapes, squared hourglass vents that mirror the look of the taillights and a lunar theme that incorporates the topography of the Sea of Tranquility into things like the floor mats and speaker covers. It also has a large infotainment screen as well as a digital instrument panel. The Hummer pickup will be offered with a number of electric powertrain options, the most powerful of which will provide 1,000 horsepower and a 0-60 mph time of less than three seconds. Like the rest of the next generation of GM EVs, it will use the automakerÂ’s new Ultium modular battery and powertrain technology. While we donÂ’t have further details about a potential reveal date, we also know a Hummer electric SUV based on the pickup will follow at some point. It, too was on display at GMÂ’s EV Day. It looks exactly like the Hummer pickup from the rear doors forward, but with a shorter wheelbase and enclosed cargo area in the rear. It also sported a liftgate-mounted spare.
