GMC Syclone spools up a storm on Jay Leno's Garage

A storm was brewing on American roads in the early 1990s. That's when Detroit's automakers were producing some of the hottest performance trucks ever devised – models like the Ford Lightning, GMC Typhoon, and its flyweight pickup sibling, the GMC Syclone. Jay Leno just happens to have one of the latter in his garage, and took it out to showcase in this latest video segment. The Syclone was an exercise in absurdity, and could not only trounce any other pickup on the road, it could outrun anything else GM made and just about anything else on the road – beating Ferraris and Porsches off the line. In a pickup, for crying out loud. The kicker is that its engine wasn't such a monster, either: under the hood sat a 4.3-liter turbocharged V6 pumping out what would seem by today's standards to be an adequate 280 horsepower and 350 pound-feet of torque. Even the smaller of the EcoBoost V6s available in today's Ford F-150 produces more than that. But in a lightweight, compact pickup, those figures were enough to propel the Syclone to 60 in 4.3 seconds and run the quarter-mile in 13.6 seconds. Long before the dune-jumping Ford F-150 SVT Raptor or even the Viper-powered Dodge Ram SRT-10, GM made fewer than 3,000 Syclones based on the compact Sonoma (sister to the Chevy S-10) and another 4,700 of the Typhoon, which was mechanically similar but more practical (albeit heavier) wagon bodywork from the Jimmy. But as Jay aptly points out, the Syclone was the one you wanted. Scope it out in the ten-minute video clip above.

GM ending stop-sale order on heavy-duty trucks

General Motors responded to an inquiry from Autoblog regarding a stop-sale order on its full-size heavy-duty pickup trucks. Here's GM's official statement. GM is committed to building the highest quality products possible. We paused delivery on a small number of HD pickups with the 6.6 liter Duramax engine last week to finalize an investigation into a potential quality issue. The investigation has been completed and the stop sale will be lifted for the small number of vehicles at dealerships.Customers can be assured GM’s heavy duty pickups are covered by a 5 year/100,000 mile powertrain warranty. The original article continues below. General Motors has reportedly sent its Chevrolet and GMC dealers a stop-sale order that applies to some examples of the 2022 Silverado HD, the 2022 Silverado MD, and the 2022 Sierra HD. The units affected by the stop-sale order may develop an engine-related problem. Citing anonymous sources, website GM Authority wrote that the Duramax 6.6-liter turbodiesel V8 in the affected trucks can hydrolock, which means liquid could enter the cylinders and cause a substantial amount of damage. The report does not specify where the liquid would come from; hydrolocking can happen by driving through a deep puddle of water, for example, but a large amount of coolant can cause it as well. The publication adds that the stop-sale order was assigned internal reference number N222362910. It also notes that the trucks included in it can't be sold, delivered to buyers, traded with another dealer, sent to auction, or even used for demonstration purposes until further notice. Earlier in April 2022, GM Authority reported that General Motors planned to buy back an unspecified number of Silverado HD and Sierra HD trucks due to quality-related issues with the 6.6-liter V8. Details about the problems experienced by customers haven't been released; all we know is that each truck will be replaced, though the replacement may not have the same equipment due to the ongoing chip shortage.

2021 GMC Canyon AT4 Road Test | The everyday tool

Bold take: The GMC Canyon is the most well-rounded midsize truck. Admittedly, “well-rounded” is a lukewarm compliment, but the Canyon does nearly everything well. It is not the flashiest, which is undeniably the Jeep Gladiator. Or the most comfortable, which is the Honda Ridgeline. But for those seeking a midsize truck that looks like a truck, drives like a truck and has a solid interior, the Canyon is the right formula. We would test the 2021 GMC Canyon AT4 for a week and find that itÂ’s pleasant, capable and sturdy off-road. We would haul a bookshelf in the bed, get dirty during a woodsy soft-road jaunt and pile up the miles running around town. In short, itÂ’s exactly what most need in a midsize truck.  The AT4 model is new for 2021, and it replaces the All-Terrain model, a move GMC is rolling out across its lineup. The AT4 adds an off-road-tuned suspension with hill-descent control, beefy 31-inch Goodyear Wrangler DuraTrac tires wrapped around 17-inch aluminum wheels, standard four-wheel drive with locking rear differential and a transfer case skid plate. The AT4 punches up the CanyonÂ’s appearance with red tow hooks, dark chrome elements and a bigger grille thatÂ’s similar to the SierraÂ’s. The Canyon Denali, which was also refreshed for ‘21, is showier, but the AT4 trim feels cooler with its understated off-road vibes. Considering this, we head out for an afternoon drive along a familiar route through DetroitÂ’s northern suburbs. The Canyon is a solid daily driver. The 3.6-liter V6 rated at 308 horsepower and 275 pound-feet of torque is widely used in General Motors vehicles. ItÂ’s powerful and actually sounds pretty good — even throaty — in GMCÂ’s midsize truck. Our passengers are surprised to be pulled back in their seats during hard acceleration, and the eight-speed automatic transmission is well-calibrated for the many jobs the Canyon is called upon to perform. This powertrain, standard in the AT4 and Denali trims, is a step up from the 2.5-liter inline-four and six-speed auto offered on the lower models. ItÂ’s worth it. The 2.8-liter Duramax diesel is an option on higher-spec Canyons, and its 369 lb-ft of torque is tantalizing. For everyday use, take the V6. Our tester with the gasoline V6 and four-wheel drive can tow as much as 7,000 pounds, has a maximum payload of 1,609 pounds and has respectable fuel economy of 17 mpg in the city and 24 mpg on the highway.
