2022 Chevrolet Silverado LT Trail Boss adds 3.0-liter diesel option

Order books just opened for the 2022 Chevrolet Silverado, which, in case you hadn't heard, is almost unchanged compared to the 2021 Silverado. The overhauled Silverado and GMC Sierra that we caught in spy shots several times last year and were expected to launch this year have been delayed. Until that pickup gets here, Chevrolet and GMC will add "Limited" to the names of the Silverado and Sierra. Fleet guides for next year's truck show the official model name as Chevrolet Silverado 1500 LTD. There are a few interesting features coming next year, though, like the Multi-Flex tailgate joining the options list for Silverado HD trucks. GM Authority also reports that the 2022 Silverado LT Trail Boss adds the 3.0-liter oil-burner with 277 horsepower and 460 pound-feet of torque as a third engine option, which should be a big treat for the off-roading crew. Whereas the GMC Sierra AT4 already offers the 3.0-liter diesel, the Silverado LT Trail Boss only offers the 5.3-liter and 6.2-liter V8s, both bolted to GM's ten-speed automatic transmission. Then there's the Custom Trail Boss that adds the 4.3-liter V6 as an option, and it and the 5.3-liter V8 only get 6-speed automatics. At the moment, Silverado trims that offer the Duramax charge a $1,045 for it over the 5.3-liter V8. If that gap holds true for next year, the diesel will just about evenly split the price difference between the LT Trail Boss with the 5.3 and the 6.2.   Elsewhere in the range, Driving.ca said Canadian fleet guides show the 4.3-liter V6 and lower-spec 5.3-liter V8 with Active Fuel Management (AFM) instead of Dynamic Fuel Management (DFM) disappearing from next year's base Silverado WT. To clarify, AFM only shuts off half the cylinders in certain conditions, whereas DFM constantly adjusts how many cylinders are firing all the time. As it stands, that would leave the 2.7-liter turbo four-cylinder as the only engine option. However, those other two mills were the only ones left in the lineup that shift through a six-speed transmission, making it possible that they'll rejoin the options list with at least two more gears to choose from. It's not clear if GM will sell the Limited models alongside the majorly upgraded 2022 Silverado. The automaker did just that a few years ago, selling the previous-gen truck as a Limited trim alongside the then-new, current-gen. It certainly wouldn't be the only company to do so, either.

Before Chevrolet's Redline, there was the Saturn Red Line

While Chevy rolls out Redline special editions across more of the lineup at this year's Chicago Auto Show, we've been eating some 'member berries and started thinking about the last time GM used the term. Back in 2004, Saturn rolled out Red Line (two words) editions of the Ion and Vue. The lineup was joined by the Sky Red Line in 2007, and the second-generation Vue kept the tradition going in 2008. This was in the heady days of the mid-2000s, before the financial crisis and GM's bankruptcy reorganization that saw the end of Saturn. The press release headline for the 2008 Sky is now cringe-worthy: "Hot-selling Sky helps drive Saturn product renaissance." Performance lineups were the hot new thing, as automakers attempted to cash in on the tuner trend popularized by The Fast and the Furious. Chevy had SS models, Pontiac had GXP, and Saturn had Red Line. Across the Detroit Metro area, Dodge had a slew of SRT models, and Ford's Special Vehicle Team brought us the SVT Lightning pickup, the SVT Focus, and a smattering of hopped-up Mustangs. The performance cred of Red Line models varied from car to car. The Ion Red Line shared the same engine as the original Chevy Cobalt SS, a 205-horsepower supercharged 2.0-liter four-cylinder, 65 hp more than stock. Car and Driver tested one with a 0-to-60-mph time of 6.1 seconds and said the Ion "tears down the wall that has separated enthusiasts from the Saturn brand for so long." The Vue Red Line, meanwhile, came with the same optional Honda-sourced 3.5-liter V6 you could get in the regular Vue, and added a stiffer, lower suspension, bigger wheels with more aggressive rubber, and recalibrated steering assist. When the Vue was redesigned for the 2008 model year, the Vue Red Line was a similar proposition. The engine was now from GM, and up 7 horsepower to 257, but you could get it in both Red Line and XE trim. Aside from the tire and suspension upgrades, Red Line models now came with a unique front fascia and rear exhaust cutouts. The most exciting Red Line, of course, was the high-performance version of the Sky roadster, which shared underpinnings with its Pontiac Solstice twin. This model came with GM's hot 2.0-liter Ecotec Turbo, good for 260 horsepower. The extra power was crucial in covering up the Sky's unfortunate manual gearbox ratios, which left the non-turbo model aching for torque in lower gears. As we all know, Saturn was taken by the grim reaper in 2009 after an attempt to sell the brand to the Penske Group.

GM reportedly developing 2.5-liter turbo four-cylinder

General Motors is allocating a massive amount of resources to developing electric technology, but it's not forgetting about the gasoline-powered cars that make up the bulk of its sales. It's reportedly designing a new 2.5-liter turbocharged four-cylinder engine based on its 2.7. Citing "sources familiar with the matter," enthusiast website GM Authority wrote that the 2.5-liter four is "in [the] final stages of development," meaning it should be announced sooner rather than later (assuming the report is accurate). Technical details are few and far between as of writing. The publication learned that the 2.5 will be part of the Cylinder Set Strategy (CSS) family of engines and that it will be mechanically related to the 2.7-liter currently found in the Chevrolet Silverado 1500, among several other models. It will feature dual overhead camshafts. It's too early to tell which models the 2.5-liter four-cylinder will end up in, or how much power it will generate. The output will likely depend on the application. For context, the 2.7 delivers 310 horsepower at 5,600 rpm and 348 pound-feet of torque between 1,500 and 4,000 rpm in the Silverado. In the smaller Colorado, it provides anywhere between 237 and 310 horsepower depending on the trim level selected. While this is pure speculation, our crystal ball tells us the engine will end up powering crossovers. It's an easy deduction to make. We can't imagine it will be offered in the Silverado, and seeing it in the Colorado is unlikely because its entry-level engine develops 237 horsepower; there's likely not much of a market for a midsize truck with 200 or so horsepower. Putting it in the Corvette wouldn't make sense and the Camaro has nearly reached the end of its life cycle without a successor planned. This leaves us with Chevrolet's range of crossovers, like the Equinox, as well as their GMC-, Buick-, and Cadillac-branded counterparts. We're not discounting the possibility that the cars set to receive the 2.5 haven't been unveiled, but those are likely crossovers, too; the odds of seeing another big Chevy sedan are very, very low. General Motors hasn't commented on the report, and it hasn't publicly announced plans to expand its CSS family of engines. If the report is accurate, we should learn more about the new turbocharged, 2.5-liter four-cylinder engine in the not-too-distant future.
