GM Authority did some digging to find out why. First, a little background. Previously, the Chevrolet Blazer and Chevrolet Traverse both offered an advanced, dual-clutch AWD system that could split torque front to back, as well as between the two rear wheels. Available for the 2020 model year on both RS and Premier trim levels, the system provided greater control and less braking intervention than the “regular,” less-complex AWD system offered on other trim levels. Now, although it’s still available on RS trims, the 2021 Blazer Premier and 2021 Traverse Premier no longer offer the advanced dual-clutch AWD system. GM Authority reached out to senior marketing director, Chevrolet SUVs, Brad Franz for an answer as to why General Motors elected to no longer offer the advanced AWD system on the Premier trims in the 2021 model year.
