With a strong, square face and leaning heavily on off-road capability, the Silverado largely maintains course in an ever-changing world. And, two new V-8s!

Hitting dealerships at the end of this year, the 2027 Silverado starts its fifth-generation (The Silverado named first appeared in 1999). It, of course, gets new styling, more and bigger screens inside, and refinements to its off-road capability. But it also continues to offer two V-8 engines. They both remain naturally aspirated. And they actually grow in displacement.

Two New V-8s

Ditching both current V-8s, the 5.3-liter, which makes 355 horsepower and 383 lb.-ft of torque gives way to a 5.7-liter replacement. And the big boy 6.2-liter, spinning up 420 horsepower and 460 lb.-ft., gets put out to pasture for an even bigger boy, a 6.6-liter. Wow.

And while Chevrolet boasts about more power and torque, not a word on efficiency or fuel economy. I only mention the E words because fuel prices remain crazy high. And the idea of spending $110 per fill-up makes me a little sick. By the way, that’s not an exaggeration. The current regular cab truck offers a 28.3-gallon tank. At $3.93 per gallon on average in the U.S., topping that tank off would cost: $111.19.

I imagine, and hope, that these engines may well also offer greater efficiency as well. But, for the moment Chevrolet kept mum about both peak outputs and fuel economy estimates. We do, however, have a glimpse as Chevrolet released information about a new 6.7-liter engine for the Corvette. That engine outputs 535 horsepower and 520 lb.-ft. of torque.

I doubt the truck engine will match that, but I bet it will offer something well above 450 horsepower and torque may indeed match 520 lb.-ft. As for the 5.7-liter, I bet we see a peek horsepower figure with a four and torque in the 450 lb.-ft neighborhood.

Two Other Engines

The 2027 Silverado will continue to offer a 3.0-liter diesel engine and a turbocharged 2.7-liter inline-four. Chevrolet didn’t explicitly say but expect the 310 horsepower and 430 lb.-ft of torque to remain the output figures of the turbo-four. However, it now gets the 10-speed automatic.  The Diesel will also likely carry-on with 305 horsepower and 495 lb.-ft of torque.

Engine Theory

But the exact details of engine output, displacement, and even efficiency ultimately all come second to the fac that Chevrolet continues to offer two naturally aspirated V-8s in their trucks. And indeed, making them bigger.

Engine downsizing and electrification continue to proliferate through the industry, even in trucks. And while Ford still offers a 5.0-liter V-8 in the F-150 and Ram recently brought back the Hemi 5.7-liter in its full-size pickup, GM remains the only brand to offer V-8 options.

In the near term, this makes perfect sense. Especially among truck buyers, the pushback against any significant change is omnipresent. But, longer term, will it stand? I go back to that $110 leaving your pocket every time you roll up to the gas station.

But here’s the real beauty in what GM did here. If folks start headed towards alternate power sources, the Chevrolet Silverado EV stands ready and able take the mantle.

Other Changes

All new Silverado trucks will see more and bigger screens inside. Standard equipment includes a 12.2-inch digital instrument cluster and a 16.3-inch center display.  Moreover, the ZR2 and High Country trims will also get a 11.5-inch passenger display screen as well as a head-up display. Plenty to look at. Higher trims will also offer dual wireless smartphone charging.

And the truck does indeed look nice. Sharp angles cut into an otherwise squared-off body. Up front, you get a bold face with a large grill and sleek looking headlights. But—you know—it still looks like a truck.

Trims

For 2027, Chevrolet will offer seven Silverado trims. Three of them lean into the off-road friendly side of trucks. They are the Trail Boss, Custom Trail Boss, and ZR2. The other four are the base Work Truck (WT), then the Custom, Silverado (what used to be the LT), and top-of-the-line High Country.

All three off-road trucks offer some level of lift. Furthermore, the two Trail Boss versions get a 34-inch mud terrain tire and the ZR2 rocks a 35-inch mud terrain tire.

Conclusion

I am super curious to learn more about these engines. And, more holistically, how the latest Silverado fits in with the modern vehicle market. I bet they sound great, make big power, and don’t chug fuel as badly as some may fear. But, oof, $110, I dunno.
