Chevy reintroduced the Blazer nameplate for the 2019 model year as an all-new mid-size crossover utility vehicle. Although the latest 2021 Chevrolet Blazer drops in mostly unchanged, there are a few alterations here and there, including a revision to the equipped AWD system based on trim level.
First, a little background info. The latest generation Chevrolet Blazer comes standard with FWD, while AWD is offered as an available option. As it turns out, customers can get one of two different AWD systems based on the trim level selected. These include either the “regular” All-Wheel Drive system (RPO code F48), or the Advanced Twin-Clutch All-Wheel Drive System (RPO code G99).
For 2019 through 2020 model year vehicles, the more advanced twin-clutch G99 system was offered on RS and Premier trim levels. All other trim levels offering AWD (2LT, 3LT) were equipped with the “regular” F48 All-Wheel Drive system.
Now, with the introduction of the 2021 Chevrolet Blazer, that changes. For the latest model year of the next-gen Blazer, the Premier trim level is equipped with the “regular” All-Wheel Drive F48 system. As such, the sporty RS trim level is the only 2021 Chevrolet Blazer to offer the more-advanced G99 Advanced Twin-Clutch All-Wheel Drive System.
To note, the base-model L and 1LT trim levels are both offered exclusively with FWD, which is unchanged compared to previous model years.
While the “regular” F48 All-Wheel Drive system enhances traction considerably over the standard FWD setup, the G99 Advanced Twin-Clutch All-Wheel Drive System takes it a step further, independently controlling torque at each rear wheel, and thus providing even greater control and less braking intervention. The G99 Advanced Twin-Clutch All-Wheel Drive System is equipped with an automatic locking rear differential, and will accurately apply torque between the left and right rear wheels, as needed.
