C-Class emphasizes polished luxury. 3 Series keeps a sharper sports-sedan edge.
The 2026 Mercedes-Benz C 300 uses a 2.0-liter turbocharged inline-four with mild-hybrid drive, producing 255 horsepower and 295 pound-feet of torque through a 9G-TRONIC 9-speed automatic. Mercedes-Benz lists 25 city/35 highway MPG and a 6.0-second 0–60 mph time.
The 2026 BMW 330i also produces 255 horsepower and 295 pound-feet from a 2.0-liter turbocharged four-cylinder. BMW lists a quicker 5.6-second 0–60 mph time and 28 city/35 highway MPG for the rear-wheel-drive 330i.
For NYC drivers, the distinction is less about raw output and more about personality. The C-Class offers a more luxury-forward cabin and Mercedes-Benz digital experience, while the BMW continues to place more emphasis on sporty steering and acceleration.
