Cabs

And when it comes to cabs and beds the GMC Sierra offers a combo to suit all needs.  However, it's notable that the regular cab only comes in the base model Sierra.    The SLE and Elevation, a double cab is standard with the option for the bigger but still four-door crew cab.  As well the SLT, AT4, and Denali are all standard and only offered, in the larger crew cab.

Beds

Only the Sierra base model comes with a long bed.  And pretty much the rest of the trim/cab combos offer a standard or short box.

Engines And Transmissions

As with the overall trims and the cab/bed combos, Sierra's engine offerings are vast.  Because whether you go with a two-wheel drive or a four-wheel drive, you have a total of five different powerplants to choose from.

To be clear, not every engine is available with every trim.  But, the point is reinforced that Sierra has all-comers covered.  Because there are so many engine options below is a summary.

2021 GMC Sierra Engines:

2.7-liter turbo inline 4-cylinder, 310 horsepower, 348 pound-feet of torque

3.0L turbo diesel, 277 hp, 460 lb-ft of torque

4.3L V6, 285 hp, 305 lb-ft of torque

5.3L V8, 355 hp, 383 lb-ft of torque

6.2L V8, 420 hp, 460 lb-ft of torque

So each of these engines matches with a different transmission to produce various results.  Regardless of the specific transmission, each is automatic.

Automatic Transmissions:

10-speed:

2.7L turbo 4-cylinder

3.0L turbo diesel

5.3L V8

6.2L V8

8-speed:

5.3L V8

6-speed:

4.3L V6

5.3L V8

All the above should be plenty to confuse the most serious mind.  If not, there's another factor.  And that's the fuel management system.  Specifically, whether the engine and transmission combination comes with an active or dynamic fuel management system.

So, with all of these combinations,
