2021 Mercedes-Benz Metris

The 2021 Mercedes-Benz Metris is a versatile mid-size van, often praised for its maneuverability, cargo capacity, and comfortable ride compared to larger vans. However, it’s often criticized for its basic interior features, and some find the engine performance adequate but not particularly powerful. The 2021 Metris is exclusively powered by a 2.0L turbocharged inline-4 gasoline engine producing 208 horsepower and 258 lb-ft of torque, paired with a 9G-TRONIC 9-speed automatic transmission.
