Determining Chevrolet Silverado 1500 engine size for all years and trim levels

One of the iconic US pickup trucks is the Chevrolet Silverado 1500, and this year the manufacturer offers three cabs, three cargo box sizes, and seven engines. Six Silverado’s 2021 engines are fueled with gasoline and one - with diesel. Two engines are turbocharged, while five of them have atmospheric aspiration. 

There are engines with an Active Fuel Management (AFM) system. This GM’s trademarked fuel displacement technology uses only part of the cylinders to save fuel. Some engines are also equipped with the Stop-Start system that stops your engine when the car is not moving. This helps to save energy. The improved AFM technology called Dynamic Fuel Management (DFM) closes the cylinders to deliver more efficiency and power.

2021 Chevy Silverado 1500 engines are:

  • 4.3L V-6 VVT DI with Active Fuel Management
  • 5.3L V-8 VVT DI with Active Fuel Management
  • 2.7L I-4 Turbo DOHC VVT DI with Active Fuel Management and Stop/Start
  • 2WD 5.3L V-8 VVT DI with Dynamic Fuel Management and Stop/Start
  • 4WD 5.3L V-8 VVT DI with Dynamic Fuel Management and Stop/Start
  • 6.2L V-8 VVT DI with Dynamic Fuel Management and Stop/Start
  • 3.0L DOHC I-6 Turbo-Diesel

Drivetrain

Both engines with the AFM (4.3L and 5.3L) have a 6-speed automatic transmission. The two-wheel-drive 5.3L engine and 6.2L with the DFM system have an 8-speed automatic transmission, while the other three (6.2L, 3.0L turbo-diesel, and four-wheel-drive 5.3L) boast the 10-speed automatic drivetrain.

Horsepower

The horsepower of the 4.3L is 285 hp @5,300 rpm, 2.7L turbo possesses 310 hp @5,600 rpm, and 6.2L boasts 420 hp @5,600 rpm. Both 5.3L DFM and AFM engines have 355 hp @5,600 rpm, while turbo-diesel 3.0L owns the minimal 277 hp @3,750 rpm.

Torque

The torque of the 4.3L engine is equal to 305 lb.-ft. @3,900 rpm, all three 5.3L engines have the same 383 lb.-ft. @4,100 rpm and 2.7L owns 348 lb.-ft. @1,500-4,000. The 6.2L engine has a torque of 460 lb.-ft. @4,100 rpm, while the 3.0L turbo-diesel possesses 460 lb.-ft. @1,500 rpm.

Towing Capacity

The towing capacity of the engines depends on the configuration. This way, 4.3L engine is 7,200 - 7,900 pounds; the car equipped with the 2.7L engine can tow 9,000- 9,600 pounds. 6.2L engine has the largest towing capacity of 9,200 - 13,300 pounds, while the 3.0L turbo-diesel can tow 9,000 - 9,500 ponds. The 5.3L ones tow 9,300 - 11,500 pounds. 

Payload 

The payload depends on the configuration and number of powered wheels (2 or 4). The max payload is equal to 2,160 - 2,280 pounds for the Regular cab, and the Double cabin can be loaded with 1,780 - 2,190 pounds. The Crew cab’s numbers vary from 1,820 to 2,180 pounds. 

BE CAREFUL

Chevrolet Silverado 1500 with a larger engine size costs more in terms of miles per gallon and insurance but has better acceleration.
