The updates and changes described here are specific to the U.S. market and may differ for other markets.
The 2020 GMC Sierra 1500 is available as a light-duty full-size pickup truck with several cab and bed configurations.
- Three Cabs:
- Regular Cab
- Double Cab
- Crew Cab
- Three Beds:
- Short Bed
- Standard Bed
- Long Bed
The cab and bed choices can be configured in the following configurations
- Crew Cab, Short Bed
- Crew Cab, Standard Bed
- Double Cab, Standard Bed
- Regular Cab, Standard Bed
- Regular Cab, Long Bed
We should note that each of the above body configurations is available with either a rear-wheel or four-wheel drivetrain assembly.
Additionally, all remaining 2020 GMC Sierra 1500 production was restricted to the crew cab body style in September. The restrictions are in effect until the end of the current 2020 model year, with production of the 2021 model year kicking off September 14th for double cab and crew cab models, and September 21st for regular cab models.
The 2020 GMC Sierra is offered with the following engine and transmission choices:
|Engine||Fuel||Aspiration||Transmission||Horsepower @ RPM||Torque @ RPM||Axle Ratio|
|4.3L LV3 EcoTec3 V6||Gasoline||Atmospheric||6-speed automatic MYC||285 @ 5300||305 @ 3900||3.42|
|2.7L L3B I4||Gasoline||Turbocharged||8-Speed Automatic (MQE)||310 @ 5600||348 @ 1500-4000||3.42|
|5.3L L82 EcoTec3 V8||Gasoline||Atmospheric||6-Speed Automatic (MYC)||355 @ 5600||383 @ 4100||3.42|
|5.3L L84 EcoTec3 V8||Gasoline||Atmospheric||2WD 8-Speed Automatic (MQE) / 4WD 10-Speed Automatic (MQB)||355 @ 5600||383 @ 4100||3.42|
|6.2L L87 EcoTec3 V8||Gasoline||Atmospheric||10-Speed Automatic (MQB)||420 @ 5600||460 @ 4100||3.23|
|3.0L LM2 Duramax I6||Diesel||Turbocharged||10-Speed Automatic (MQB)||277 @ 3750||460 @ 1500||3.23|
As stated, the 2020 Sierra 1500 continues to be offered in either rear-wheel or four-wheel drive configurations. Notably, Chevy made a parts change halfway through the 2020 model year, resulting in High Country 4WD models being equipped with the eight-speed automatic transmission rather than the newer ten-speed unit. To compensate for the older technology, GM is offering buyers a $200 credit.
Another noteworthy change is a $1,500 price reduction for Sierra 1500 Diesel models, which GMAuthority was the first to report. Effective September 3rd, 2020, the change in MSRP will also apply for in-stock and in-transit units of the 2020 GMC Sierra Diesel 1500.
The 2020 Sierra 1500 became available at the end of Q2 2019.
We expect the fourth-generation Sierra 1500 to remain in production through the 2025 model year.
An all-new, next GMC Sierra 1500 will most likely launch after the 2025 model year.
