We don’t have to pity a truck with a humble four-cylinder engine anymore. General Motors’ corporate twins the Chevrolet Silverado and GMC Sierra are the only two full-size trucks that can be ordered with a four-cylinder motor. But, the four cylinder beats the GM 5.3-liter V8 in one key measurement that truck people care about: torque. While the four cylinder weighs less and gets better gas mileage, it twists harder than the 5.3. The V8 makes 383 pound-feet, while the four cylinder makes 430 pound-feet. That’s significant for when you’re towing. Sure, the V8 makes more horsepower, but only 45 more horses propel the V8 truck.
For 2022 General Motors enhanced the 2.7-liter four cylinder. The 2021 and earlier versions of the 2.7-liter made 348 pound-feet of torque. It is now the standard engine in the Work Truck, Custom, Custom Trail Boss and LT truck trims.
Is the 2.7-liter turbo a good truck engine?
The base Sierra and Silverado can be ordered with a new 2.7-liter four cylinder. The engines make 310 horsepower and 430 pound-feet of torque. The trucks with four cylinders are rated at 19 miles per gallon in the city, and 22 on the highway for the two-wheel drive version.
For comparison, just 10 years ago the big V8 option in the same trucks made 315 horsepower, and far-less torque at just 335 pound-feet. And, just 10 years ago, the trucks were rated at 15 miles-per-gallon in the city and just 21 on the highway. That’s an improvement that will save you a lot at the pump.
Power and fuel economy make the four an attractive option
Trucks are measured on torque, and four cylinder Silverado and Sierra can tow
In your sports car you want horsepower for going fast. In your truck you want torque for towing and hauling. The Silverado can tow 7,200 pounds and haul 2,280 pounds of payload when equipped with the 2.7-liter four. That’s enough for most jobs.
Of course the Ford F-150 with the smallest 2.7-liter turbocharged V6 can tow 8,500 pounds. That truck is rated at 20 mpg in the city, and 26 mpg on the highway.
What else is new in ’22?
There’s a lot to like about the new 2022 GM trucks. The trucks were redesigned for 2022 and the eagle-eyed can spot them in a rear-view mirror easily by the new high-waisted grille. Inside, the trucks also have new interiors and larger standard touchscreens.
While the four cylinder Silverado and Sierra are impressive, the 2022 GM twins can be ordered with two different V8s, including the 6.2 liter V8 with a 10-speed automatic or the 5.3-liter V8, as well as a 3.0-liter Duramax turbo-Diesel.
What’s the difference between a Sierra and a Silverado?
There’s not much difference between a Sierra and a Silverado. The Sierra is the more-stately version of the two. While it looks an awful lot like the Silverado, it can be upgraded to a Denali (though not with the four-cylinder) that brings leather, big digital screens and power everything. GMC also sells the the AT4X version that is the off-road package, which has a lift and the special Multimatic shocks, but again, not with the four cylinder.
The trucks are basically the same, but they have slightly different options packages and interior trim.
