About the 2021 Mercedes-Benz AMG GLB
1st generation (X247), first U.S. model year for the AMG GLB 35
Mercedes-AMG positioned the GLB 35 as a compact performance SUV that does not give up everyday usefulness. Its squared-off body creates useful passenger and cargo room, while the stronger turbo engine, quick-shifting transmission, AWD, adaptive suspension, and selectable drive modes deliver a more energetic driving experience than the regular GLB. Its key distinction is the combination of small exterior dimensions, flexible interior space, modern screens, and sports-car-inspired responses.
The 2021 AMG GLB 35 pairs the GLB's upright, space-efficient body and sliding second row with much quicker performance and sharper handling. Standout features include five drive modes, adaptive suspension, dual 10.25-inch displays, smartphone integration, and power sport front seats with memory.
