When you’re operating a luxury sedan, nothing should stop you from surging down the highway. Fortunately, the 2022 BMW 330i comes equipped with a 2.0L BMW TwinPower Turbo engine. With this powertrain, you’ll whizz down the streets with these impressive performance specs:
The Mercedes-Benz C 300 also comes with a 2.0L turbo engine that produces 255 horsepower. Where it falls behind the 330i, though, is with torque and acceleration. This engine only produces 273 lb-ft of torque and allows you to go from 0 to 60 MPH in 5.7 seconds.
To ensure you can enjoy this power on nearly any terrain, both the 330i and the C 300 come with optional all-wheel drive (AWD) capabilities.

Both BMW and Mercedes-Benz know the safety of you and your passengers is the most important thing when you’re behind the wheel. That’s why these sedans come standard with advanced safety features. To provide a range of protection around your vehicle, these safety features rely on cameras and sensors to monitor and alert you to potential hazards you may encounter.
The BMW 330i comes equipped with Active Guard. The C-Class doesn’t come with a specific suite of safety features, but still offers plenty of safety options.
Some of the features you can find in the BMW 330i include Frontal Collision Warning and Automatic City Collision Mitigation and Braking. With this feature, a range is monitored ahead of your vehicle and can provide an alert, so you can make any necessary adjustments.
If there’s no reaction to this alert, under certain circumstances automatic braking can step in to help avoid a collision.
A similar feature is offered with the C 300, making both models safe options.
When purchasing a new vehicle, you must make sure there’s enough room for you and your passengers to stretch out comfortably. Thankfully, both sedans provide plenty of space with their roomy dimensions.
Exteriorly, both vehicles are about the same length, with the C 300 measuring 184.5 inches, while the 330i is slightly larger at 185.7 inches.
Let’s take a look at how the overall size of these sedans affects their interior dimensions!

Both front- and rear-seat passengers will likely have an easier time stretching out in the BMW 330i than in the Mercedes-Benz C 300 because of its larger size.
Plus, the 330i offers extra cargo space, too. This sedan comes with 13 cubic feet of cargo space. The Mercedes-Benz C 300, on the other hand, only has a maximum cargo capacity of 12.6 cubic feet. While that doesn’t seem like a big difference, nearly half a cubic foot of cargo capacity means you can easily fit an extra bag into the trunk of your 330i when preparing for a road trip.

Your ride to work should be supported by a host of comforting amenities. That’s why the new BMW 330i includes 10-way power front sport seats with power side bolsters. With these features, you’ll easily discover the best position for your unique proportions.
While the new Mercedes-Benz C 300 also contains power-adjustable seats, these chairs don’t provide the same number of position selections and comfort as what you’ll have inside the BMW 330i.
Plus, the 330i takes comfort a step further by offering Automatic 3-Zone Climate Control as a standard feature. With this, you, your copilot, and your rear-seat passengers can independently set and adjust your climate settings throughout your commute.
The C 300 only allows you and your front-seat passenger to make these independent changes, since it only comes with dual-zone automatic climate control.
You deserve a vehicle that’s as much of a high achiever as you are. When it comes to comparing the BMW 330i vs. Mercedes-Benz C 300, only the 2022 BMW 330i will make the most of every inch on the streets near Stratham, Portsmouth, and Exeter, New Hampshire.
