GMC Syclone pickup returns via Special Vehicle Engineering

The original GMC Syclone was a 1991 mid-size Sonoma pickup turned muscle truck. Its heavily modified 4.3-liter V6 sported a turbocharger, intercooler, and modified internals, raising output to a Corvette-baiting 280 horsepower and 350 pound-feet of torque. The engine was paired with a four-speed automatic, rear-biased all-wheel drive, and four-wheel antilock brakes (the coming thing). With an all-black livery and a lowered ride height, the Syclone looked the business, and backed up those looks with a 0-to-60 time of 4.3 seconds and a 13.4-second quarter-mile, according to contemporary magazine testing. Given all the recent interest in high-performance pickups, it's amazing that GMC hasn't revived the Syclone. But where manufacturers leave an opening, the aftermarket steps in — in this case that's Specialty Vehicle Engineering, which as CNET reports is resurrecting the nameplate for a build of 100 new Syclones, based on the GMC Canyon, which will update the idea a lot more horsepower. The 2019 Syclone takes as its starting point the extended-cab version of the Canyon. The engine is again a V6, this time a 3.6-liter fitted with a supercharger and a custom cat-back exhaust system, upping output to 455 ponies from the stock 306. SVE's Syclone can be had with rear- or all-wheel drive, and it, too, features upgrades to the brakes and chassis. Six-piston front calipers are fitted in place of the standard four-piston units, and the slotted front rotors are upsized from 12.2 inches to 13.6. The suspension is lowered by two inches up front and five inches at the rear, with stiffer traction bars, bushings, dampers, and a heftier rear anti-roll bar. Unlike the original, the modern Syclone can be had in colors other than black — any of the standard Canyon hues are available — but the appearance is customized with rocker-panel extensions, body-color grille and rear bumper, and a composite hood insert. The interior gets embroidered logos and badges, including a numbered plaque on the dash. The price for the Syclone is $39,995 — that's for the package, on top of the cost of the truck. But at least ordering is easy: The Syclone package can be ordered through select GMC dealers.

GMC Sierra Denali CarbonPro bed is finally, almost here

GMC revealed the Sierra 1500 with the optional CarbonPro bed on March 1, 2018. The bed wasn't available at launch, though. You can't buy it now, either, but it will hit dealerships with limited availability after production starts in early June, exclusively for the Denali 1500 and AT4 1500 trims. The carbon floor and sides replace the steel panels in a normal bed, providing "strength, durability, and scratch resistance" and a potential 59-pound weight saving, depending on the truck's configuration. To make sure the bed had a chance, development engineers replicated "extreme use scenarios" like dropping 1,800-pound gravel loads, 450-pound steel drums, and cinder blocks from various heights. They put a 250-pound man on a snowmobile with studded tracks, had him drive into the bed and then go wide-open throttle. We're told the result was "minimal scratching." On top of the extreme weather testing any vehicle goes through, the team also put a generator in the bed and aim the exhaust into a corner to ensure vibration and direct heat wouldn't deform the carbon fiber. Because of the finer shaping area-specific strength possible with carbon fiber, the bed provides one cubic foot of additional payload space by having its sidewalls pushed further out. The CarbonPro bed doesn't need a bedliner, and is grained at the top for better traction but smooth on the bottom for easier hosing down and dirt removal. Tie-downs at the front of the bed work with molded indentations to hold motorcycle tires, and slots in the sidewalls hold two-by-sixes. The truck maker says the carbon-lined payload area confers "best-in-class dent, scratch and corrosion resistance," but we suppose the nation's pickup truck army will prove that or not. The trucks likely won't have the hardest life at the start, since the Sierra Denali costs $56,790 before even a basic option like four-wheel drive. The real test probably won't come until around 2029, when third owners begin treating their aerospace-inspired thoroughbreds like dray horses.

GM 8-speed transmission lawsuit granted class action certification

A story on Autoblog about potentially faulty 8-speed automatic transmissions from General Motors in 2019 has, as of the day this was published, 166 comments, mostly from owners of cars and trucks who say they are experiencing "a hesitation, followed by a significant shake, shudder, jerk, clunk, or 'hard shift' when the vehicle's automatic transmission changes gears." At the time, lawyers were seeking statewide classes in at least six states. As of today, the Detroit Free Press reports that a judge has granted class action status to a lawsuit brought by 39 plaintiffs across 26 states covering the transmission issue. The lawsuit specifically applies to vehicles that are equipped with GM's 8L90 or 8L45 8-speed automatic transmissions made between 2015 and March 1, 2019. Both of these transmissions are similar units, the 8L45 being slightly lighter version used in fewer vehicles than the beefier 8L90, and are designed for front-engine, rear- or all-wheel drive applications. The lawsuit alleges that the erratic transmission behavior makes some vehicles unsafe to drive. Ted Leopold, partner at Cohen Milstein and the court-appointed lead counsel for the case, said in a statement, "General Motors knowingly sold over 800,000 eight-speed transmission vehicles, which they knew to be defective for years, and yet made the business decision not to tell its customers before purchase." He added, "Dealers were directed to tell the customers that harsh shifts were ‘normal' or ‘characteristic.Â’ Such decision making is both highly irresponsible and emblematic of what GM believes it can get away with." The vehicles included in the court order with potentially faulty transmissions includes: 2015-2019 Chevrolet Silverado 2017-2019 Chevrolet Colorado 2015-2019 Chevrolet Corvette 2016-2019 Chevrolet Camaro 2015-2019 Cadillac Escalade and Escalade ESV 2016-2019 Cadillac ATS, ATS-V, CTS, CT6, and CTS-V 2015-2019 GMC Sierra, Yukon, Yukon XL, and Yukon Denali XL 2017-2019 GMC Canyon Some additional details of the lawsuit can be found at the Cohen Milstein site, including claims that "since 2015, GM has issued thirteen versions of a “technical service bulletin,” or “TSB,” related to this shifting issue alone." The statement from Cohen Milstein says that a "second action regarding GM vehicles with 8L transmissions is also underway in Battle v. General Motors, LLC, 2:22-cv-108783.
