The new for 2021 Suburban enters the modern era with an independent rear suspension that improved ride comfort, handling and third-row room. This is a massive vehicle that’s very functional, comfortable and high-tech. The standard 5.3-liter V8 is mated to a 10-speed automatic transmission and together the powertrain supplies plenty of predictable uninterrupted power. The ride is comfortable but steadier in the Premier trim. Handling is rather ponderous but safe. The enormous cabin is eerily quiet. Controls are very easy to use except for the tricky gear selector. It’s a big step to get into the Suburban and the tall hood cuts forward visibility. Forward collision warning and automatic emergency braking with pedestrian detection are standard. Updates for 2022 include standard lane keeping assistance and lane departure warning. Significant changes for the refreshed 2025 model include a larger 17.7-inch infotainment screen, a more powerful diesel engine and automatic emergency braking that functions at highway speeds.
