2024 Mercedes-Benz E-Class vs. BMW 3 Series

Both the 2025 E-Class and the 3 Series come standardly equipped with a 2.0-liter engine, delivering the same amount of horsepower (HP) and torque: 255 HP and 295 lb-ft of torque. In either model, you’ll enjoy smooth performance and responsiveness with ample acceleration.

Each model is equipped with an automatic transmission: 9-speed in the 2025 E-Class and 8-speed in the 3 Series. The additional gear provides finer control over engine output, helping optimize performance. That said, where the 2025 E-Class and the 3 Series differ significantly is in their drivetrains.

The 2025 Mercedes-Benz E-Class boasts standard 4MATIC® all-wheel drive (AWD), distributing power to each wheel as needed. This provides enhanced traction and stability in a variety of driving conditions. On the other hand, the BMW 3 Series comes with rear-wheel drive (AWD is available), which traditionally struggles with traction, particularly in adverse weather conditions.

The superiority of the 2025 E-Class becomes evident in inclement weather or on slippery surfaces, where its AWD provides better grip and ensures safer handling. Plus, it enhances cornering capabilities, resulting in sharper handling and a more dynamic driving experience.

These brands set a high standard with their opulent offerings. Both models boast standard leatherette seating and make leather available. Still, the 2025 E-Class sets its sights a bit higher, beginning with its base trim. The 2025 E-Class has standard heated front seats that are adjustable 10 ways, amenities that are only available in the 3 Series with an upgrade.

They both provide multi-zone climate control to ensure the comfort of everyone on board. Likewise, they each have standard ambient lighting, but there’s a major difference: The Active Ambient Lighting system in the 2025 E-Class transforms music into a visual display of colors for a total sensory experience.

The 2025 Mercedes-Benz E-Class and the BMW 3 Series offer advanced technology to enhance the driving experience, including wireless Apple CarPlay™ and Android Auto™, although you’ll quickly note their differences. The 2025 E-Class equips the 14.5-inch Mercedes-Benz User Experience (MBUX) multimedia system that includes:

• Augmented Reality Navigation
• Natural Language Understanding
• Keyword Activation (“Hey, Mercedes”)
• “Just Talk” function
• Available MBUX Superscreen Package with passenger screen

Meanwhile, the BMW 3 Series features the BMW Curved Display, which also includes a touchscreen that is over 14 inches. However, it goes without all the functionality of the multimedia system in the 2025 E-Class and has nothing similar to the MBUX Superscreen.

Both vehicles come equipped with standard sound systems, although the audio quality may be better in the Mercedes-Benz. Its standard Burmester® 4D Surround Sound System includes 17 speakers and Dolby technology to create a 360-degree listening experience.* The 3 Series’ HiFi Sound system features just 10 speakers. For a truly captivating soundstage, audiophiles may prefer the 2025 E-Class.

Mercedes-Benz and BMW are committed to providing comprehensive protection to their drivers and passengers. As such, both the 2025 E-Class and the 3 Series boast a range of standard and available ADAS technologies, enhancing the overall safety profile of each vehicle. Among their similarities are brand-specific versions of:

• Collision mitigation – front
• Active Brake Assist with Autonomous Emergency Braking
• Active Lane Keeping Assist
• Adaptive cruise control
• Active Blind Spot Assist

So, you can feel confident each time you get behind the wheel of either model.

That said, the 2025 Mercedes-Benz E-Class has some additional safety features exclusive to its brand and, therefore, not available in the BMW 3 Series. One such system, PRE-SAFE®, employs sensors to detect instability that might suggest an impending collision. It preemptively tightens seat belts, adjusts seats, and closes the windows and sunroof to add a layer of protection to occupants.

Another feature found only in the 2025 E-Class is ATTENTION ASSIST®. It monitors the driver’s behavior for signs of distraction or drowsiness, providing visual and audible warnings to encourage a break. Again, the 3 Series goes without a similar feature that adds an extra level of protection for you and everyone else on the road.
