Chevrolet Suburban SS
The Chevrolet Suburban extended-length full-size SUV has never been offered in a high-performance Suburban SS model. That said, it is possible that such a variant could come to market with the introduction of the all-new, 12th-generation model, which launched for the 2021 model year.
Chevrolet Suburban SS Status
The following is based on information gathered by GM Authority from sources familiar with GM’s product plans:
- Product plan: under consideration.
- Development status: not in development.
Imagining A Suburban SS
If a Chevy Suburban SS does come to market, it will undoubtedly be powered by the supercharged 6.2L V8 LT4 engine, which is rated at 650 horsepower and 650 pound-feet of torque in the sixth-generation Camaro ZL1.
GM Authority’s sources have told us that a high-performance Tahoe SS with the LT4 engine was under consideration as of June 2020, but the model has yet to be approved for production. However, they made no mention of a Suburban SS. That said, if a Tahoe SS does get approved for production, then we should expect that it will also bring with it a Suburban SS.
Until a high-performance Chevrolet Suburban SS comes to market, the most powerful engine in the 12th-gen Suburban lineup is the 6.2L V8 L87. The naturally-aspirated gasoline V8 engine, which is part of the EcoTec3 engine family, is rated at 420 horsepower (313 kilowatts) @ 5600 RPM and 460 pound-feet (623 newton meters) of torque @ 4100 RPM. It is mated to the new GM 10-speed automatic transmission.
