2020 BMW 3 Series vs 2020 Mercedes-Benz C-Class

Serving Seaside, CA

The 2020 BMW 3 Series is a highly-ranked small luxury sedan. The BMW gets some notable updates and changes this year to remain even more competitive. The BMW competes with several other vehicles, including the 2020 Mercedes-Benz C Class. But compared to the Mercedes, the BMW 3 Series has a higher-end infotainment system with more intuitive and user-friendly controls. The BMW also has a full interior, while the Mercedes' interior offers noticeably less legroom, headroom, and space overall for occupants. The Mercedes also has a stiffer and less smooth ride than you'll find the BMW. Overall, the BMW stands out for its comfortable ride quality, consumer-friendly tech features, and a more spacious interior.

Ride Quality

Most people think that luxury vehicles will provide them with a smooth and compliant ride. You will certainly get that with the BMW 3 Series, which offers plenty of power underneath its hood. Still, that power is complemented by a compliant suspension that absorbs bumps and uneven terrain to give you a seamless ride. The Mercedes doesn't offer the same degree of comfort, especially if you opt for the sedan with the shorter suspension system.


The interior of the BMW 3 Series is nothing less than state-of-the-art. The BMW's interior has plenty of space for the vehicle's relatively small size. The 3 Series offers comfortable seats as well, which have a standard material of simulated leather upholstery. The 3 Series also has plenty of cargo space. In comparison, the Mercedes has less room overall in both rows, but the shortage of space is especially noticeable in the back row. The Mercedes lacks the same cargo capacity as the BMW, which means the BMW 3 Series is the better choice for a road trip-worthy vehicle. The BMW also has better visibility throughout the cabin.

Technology & Features

The BMW comes with plenty of standard safety and technology. Its infotainment system is also quite user-friendly, while the infotainment system on the Mercedes is more complicated and more challenging to use. The Mercedes has a relatively clumsy touchscreen interface, while the BMW's features a visible and easy-to-use configuration. The 3 Series also comes with a standard 10.25-inch infotainment display screen with a separate digital gauge display cluster, real-time traffic information, and concierge services. The Mercedes does not get an infotainment display with up-to-date traffic and personal concierge services. The 3 Series comes with a 10-speaker sound system, while the Mercedes only has a standard five-speaker audio system.
