The BMW 3 Series and Mercedes-Benz C-Class are two of the most important and best-selling luxury sports cars in history. For decades, this duo of warring performance cars have battled for supremacy over the luxury compact sedan market. When you want to arrive at your destination with a little bit of adrenaline coursing through your veins, the 2020 BMW 3 Series is the right choice. It's a better buy than the 2020 Mercedes-Benz C-Class. And we can prove it! Check out the side-by-side comparison below to discover how the BMW 3 Series beats its Mercedes counterpart in luxury, technology and ride quality.

BMW 3 Series Front Seats

Style & Size

Despite the fact that these cars are less than an inch apart in wheelbase length, the engineers at BMW have given their sedan more storage and passenger room than you'll find in its Mercedes rival. The 2020 Mercedes-Benz C 300 provides just 12.6 cubic feet of trunk space while you get 17.0 cubic feet in the 2020 BMW 330i. And with more headroom and a little more legroom compared to the C-Class sedan, the 2020 BMW 3 Series is more spacious for a more comfortable ride.

Features & Technology

Why bother getting a luxurious sports sedan if you don't intend on using the rear seats? When you do, your back seat passengers will appreciate dedicated climate controls. 3-zone automatic climate control is standard on the 2020 BMW 3 Series, but not the 2020 Mercedes-Benz C-Class. You'll have to pay extra for that feature as an option.

Furthermore, while both vehicles come with a touchscreen multimedia system, the 2020 BMW 3 Series comes standard with a 10-speaker audio system and built-in navigation. On the 2020 Mercedes C-Class, you get a more basic five-speaker audio system and navigation is only available as an added cost option. The BMW 3 Series offers more of the features you want without costing you more!

Power & Performance

Both these vehicles have a two-liter turbocharged four-cylinder engine making 255 horsepower under the hood. But there's a catch: the 2020 BMW 3 Series sedan makes a lot more torque. 295 lb-ft of torque compared to just 273 generated by the 2020 Mercedes-Benz C-Class. That means the 2020 BMW 3 Series has even more power and quickness from a standstill. It takes the 2020 Mercedes-Benz C 300 5.7 seconds to accelerate from 0-60 MPH. The 2020 BMW 3 Series can do the same in 5.6 seconds with rear-wheel drive or as little as 5.3 seconds with optional xDrive all-wheel drive.

Not only is the BMW sedan faster in the straights, it's got a sophisticated chassis and impeccable balance so the Mercedes can't catch you in the corners and curves, either.

Oh, and one more thing? The 2020 BMW 330i gets two additional MPG compared to the 2020 Mercedes C 300, so you spend less time and money at the pump.

Safety & Driver Assistance

Both these cars are outstandingly safe in the event of a crash -- they both got 2020 Top Safety Pick awards from the Insurance Institute for Highway Safety -- but today's cars can do so much more than prevent injury in an accident. Modern driver assistance features available on both models can protect you from an accident before it happens. On the 2020 BMW 3 Series, standard Active Guard with Frontal Collision Warning, Automatic City Collision Mitigation and Lane Departure Warning keeps you protected. Lane Departure Warning is yet another feature that'll cost you extra on the 2020 Mercedes-Benz C-Class.
