Compare the2025 Mercedes CLAVS 2025 BMW 3 Series Sedan

For enhanced safety, the front and rear seat shoulder belts of the Mercedes CLA have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The BMW 3 Series Sedan doesn’t offer pretensioners for its rear seat belts.

The CLA has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. A system to reveal vehicles in the 3 Series Sedan’s blind spot costs extra.

To help make backing out of a parking space safer, the CLA has standard Rear Cross-Traffic Alert and Active Brake Assist automatically engages the brakes to help avoid a collision. BMW charges extra for Cross Traffic Warning on the 3 Series Sedan and the 3 Series Sedan’s Cross Traffic Warning does not include automatic braking.

Both the CLA and the 3 Series Sedan have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, driver alert monitors, available all wheel drive, lane departure warning systems and around view monitors.

There are over 10 percent more Mercedes dealers than there are BMW dealers, which makes it easier should you ever need service under the CLA’s warranty.

On the EPA test cycle the CLA 250 FWD gets better fuel mileage than the M340i RWD (26 city/36 hwy vs. 27 city/33 hwy).

The CLA has 2.9 gallons more fuel capacity than the 3 Series Sedan 330e’s standard fuel tank (13.5 vs. 10.6 gallons), for longer range between fill-ups.

The CLA offers a standard sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The 3 Series Sedan doesn’t offer an SMG or a conventional manual transmission.

The CLA’s drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The 3 Series Sedan doesn’t offer drift compensation steering.

For better handling and stability, the track (width between the wheels) on the CLA is 1.3 inches wider in the front and 1.4 inches wider in the rear than on the 3 Series Sedan.

For better maneuverability, the CLA’s turning circle is 3.3 feet tighter than the 3 Series Sedan’s (36.1 feet vs. 39.4 feet).

Unlike the driver-only memory system in the 3 Series Sedan, the CLA has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The CLA’s standard easy entry and exit feature glides the driver’s seat back, making it easier for the driver to get in and out. The 3 Series Sedan doesn’t offer an easy entry system.

The CLA’s standard Keyless-Go allow you to unlock the doors from any outside door handle, open the trunk, and start the engine, all without removing the key from the pocket or purse. Comfort Go standard on the 3 Series Sedan only offers hands-free access for the ignition, none to unlock the car.

Heated windshield washer nozzles are optional on the CLA to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The 3 Series Sedan doesn’t offer heated windshield washer nozzles.
