2014 GMC Sierra Regular Cab revealed

Despite initially launching in just the Crew Cab configuration, the lineup of 2014 GMC Sierra and 2014 Chevrolet Silverado trucks will eventually grow to include three cab sizes and three bed lengths. Oddly enough, our first look at the Regular Cab bodystyle has arrived in a General Motors press release discussing the aerodynamics of the new truck, with an image showing a Sierra Regular Cab testing in the wind tunnel. GMC's website says that Regular Cab and Double Cab models will be available by summer.
While it really didn't take too much imagination to figure out what the two-door version would look like, this Regular Cab Z71 looks pretty sharp with its standard-length (6.5-feet) bed - a longer bed will also be offered. In regards to the aero tuning of the 2014 Sierra, these images show just how far GM has gone in maximizing the truck's fuel efficiency and reducing its noise, vibration and harshness (NVH) levels. Interestingly, the press release shows visual evidence that keeping the tailgate up is best for aero - there's always been some Mythbusters-level contention about such things -but GM also says that adding tonneau covers (preferably soft) and running boards can also help improve the overall aerodynamics. Scroll down for all of this aero info in the official press release.

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.

2023 GMC Sierra HD 2500 and 3500 will get more expensive

GMC Sierra HD pickups are about to get more expensive again after recently becoming more expensive, according to GM Authority. In July, GMC and Buick raised the prices on certain vehicles in their lineups anywhere from $975 to $1,675 by making the previously optional OnStar a standard feature. Next year, every GMC and Buick model will adopt the upgrade. The big boy Sierra HD gets the biggest increase, being $1,500 for three years of OnStar and the Connected Services Plan plus another $175 for to be "OnStar & GMC Connected Services capable." GMA says the MSRPs for the entire 2023 Sierra HD range will be increased $1,000 on top of that. After doing the math, though, we suspect the increase could in fact be anywhere from about $800 to at least $1,100 after factoring for OnStar. The GMC configurator rings up a price of $43,670 for an entry-level Regular Cab Sierra HD Pro 2WD, GMA says next year's price will be $44,770. GMA didn't break out the next year's destination charge, it's possible GMC is adding $1,000 to the MSRP and $100 to destination. We'll find out when official pricing is announced. GMA's table shows a price of $49,795 for the least expensive SLE trim, whereas the current configurator indicates the truck can be had for $47,295 — a $2,500 difference. The SLE configurator doesn't show any charges for OnStar the way the Pro trim does. So it's possible that after backing out a potential $1,675 for OnStar, the gravy on top is just $825. Not that your wallet will care where how the potato is being sliced when the potato costs an additional $2,500 no matter what. The least dear 2022 Sierra 3500 starts at $43,195 going by the configurator. GMA says that model will command $45,970 next year, a $2,775 difference. As with the 2500 HD SLE, the configurator doesn't show the OnStar charges for the base 3500 Pro trim; subtracting the $1,675 takes us back to the $1,100 difference that appears to be at the heart of all of this. If all goes to plan, the 2023 Sierra HD will give way to a heavily refreshed 2024 model with interior upgrades cribbed from the Sierra 1500. Spy shots reveal a reconfigured instrument panel with a larger infotainment touchscreen of a likely 13.4 inches among the interior tweaks. Related video: This content is hosted by a third party.
