Specialty Vehicle Engineering's 750-horsepower GMC Canyon fully revealed

GMC's celebrated Syclone will turn 30 in early 2021, but nothing suggests the company will mark the occasion by releasing a modern interpretation of the pickup. New Jersey-based tuner Specialty Vehicle Engineering (SVE) is taking the matter into its own hands by building a limited number of GMC Canyon trucks with Hellcat-like power. Although the original Syclone received a turbocharged V6, the 2021 model gains a 5.3-liter V8 normally found in bigger vehicles, including the Sierra and Yukon. SVE rebuilt it with forged aluminum pistons, forged steel connecting rods, high-lift valve springs, a custom crankshaft and upgraded fuel injectors among other aftermarket parts. It also added a supercharger to raise the eight's output to 750 horsepower and 600 pound-feet of torque. Power flows to the four wheels via a strengthened 8-speed automatic transmission and a permanent all-wheel-drive system. For context, the first Syclone gave the Chevrolet Corvette a run for its money with a fuel-injected, 4.3-liter V6 turbocharged to 280 horsepower and 360 pound-feet of torque. These numbers were spectacular in the early 1990s since the Sonoma that Syclone was based on shipped with the 105-horse Iron Duke four-cylinder as standard. Even compared with the Sonoma GT that got a naturally aspirated 4.3-liter V6 with 195 horsepower and 260 pound-feet of torque, the Syclone was impressive. SVE installed six-pistons front calipers that clamp 13.6-inch slotted rotors, and it kept the factory brakes out back. It also lowered the suspension by two inches in the front and five inches in the back, upgraded the shocks, and added a heavy-duty rear sway bar. These modifications help drivers make the most of the extra power, but SVE hasn't published performance specifications (like the truck's zero-to-60-mph time) yet. Surprisingly, the eight-cylinder weighs almost the same as the V6 it replaces so the engine swap doesn't affect weight distribution. Visually, the Syclone can't be mistaken for a run-of-the-mill Canyon. It wears a deep front bumper, has cladding over the rocker panels and rides on 20-inch alloys. Edition-specific emblems round out the look, and the list of options includes a body-colored grille as well as a folding tonneau cover. SVE's images show a truck painted black, which was the only color offered on the 1991 model, but it's available in any factory hue. Inside, the modern-day Syclone gains special floor mats and a numbered plaque on the dashboard. Leather is optional.

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.

2023 GMC Sierra HD MSRP up at least $1,000

Once Chevrolet bumped up the 2023 Silverado and Silverado HD MSRPs by $1,000, there was no reason to think luxury cousin GMC wouldn't do the same. The proof is here, pricing for the 2023 GMC Sierra HD up on its configurator with premiums of at least $1,000 over 2022 models. As we mentioned of the Silverado, the Sierras have also tracked with the price increases we mentioned in reference to the Chevrolets; the 2022 Sierra 1500 has run up $4,700 over its cost last October, the 2022 Sierra HD is $4,100 more than it was when it hit lots last summer. That puts a 2023 Sierra HD 2500 Regular Cab long bed with two-wheel drive and the 6.6-liter V8 gas engine at a starting price of $42,995 after the $1,795 destination charge, $1,000 beyond the 2022 pickup. At the top, a Crew Cab long bed Denali with four-wheel drive and the 6.6-liter Duramax V8 starts at $83,845, which is $1,250 more than the same rig from the 2022 model year. Moving up a weight class to the Sierra 3500, the price of entry starts $1,000 more than before at $44,195. The big bad boy 3500 Denali 4WD dually starts $1,200 more than before, at $86,245. The situation's a bit cloudier when we step down two classes to the 1500. GM Authority got the price sheet for the 2023 Sierra 1500 and reports that prices are up $1,000 on most trims, but $900 up on the Denali Ultimate and $1,900 up on the AT4. GMC hasn't uploaded the configurator for the 2023 trucks yet, and GMA's price sheet is hard to parse against prices on the 2022 configurator because the end of the model year and supply chain issues have translated into mandatory discounts that can't be accounted for. For instance, the 2022 Sierra 1500 Regular Cab standard box in entry-level Pro trim has an MSRP of $40,000, yet the configurator shows the total vehicle and options price as $39,950. After the $1,795 destination charge, that comes to $41,745. Then there's a mandatory package discount of $1,500, taking the final price before any other fees to $40,245. Meanwhile, GMA's paperwork shows the 2023 price starting at $40,020 after destination, which isn't $1,000 more than any figure on the configurator. At the top end, the 2022 Denali with the Crew Cab, standard box, 4WD, and 6.2-liter V8 comes out to $71,695, only because the front and rear park assist and steering column lock aren't fitted, resulting in a $100 discount.
