Comparison: BMW 3 Series vs Audi A4 – Luxury Sedans
When it comes to compact luxury sedans, the BMW 3 Series vs Audi A4 debate is a clash of titans, each vying for supremacy in a segment defined by sophistication, performance, and innovation.
These German icons have long set the benchmark for what a luxury sedan should be, blending exhilarating driving dynamics with cutting-edge technology and refined interiors.
But in 2025, with both models pushing the envelope of design and engineering, which one truly deserves a spot in your garage?
This comparison dives deep into their strengths, quirks, and defining traits to help you decide.
As you explore these vehicles, consider how personal preferences and driving styles will influence your choice.
Performance: Power Meets Precision
The heart of any luxury sedan lies under the hood, and both the BMW 3 Series vs Audi A4 deliver engines that balance power with efficiency.
The 2025 BMW 3 Series offers a range of powertrains, starting with the 330i’s 2.0-liter turbocharged four-cylinder, pumping out 255 horsepower and 295 lb-ft of torque.
For thrill-seekers, the M340i ups the ante with a 3.0-liter inline-six, delivering a robust 382 horsepower.
Meanwhile, the Audi A4’s base 2.0-liter turbo four-cylinder produces 201 horsepower in the A4 40 TFSI, but the S4 variant, with its 3.0-liter V6, unleashes 349 horsepower for a more visceral experience.
What sets the BMW apart is its rear-wheel-drive bias (with optional xDrive all-wheel drive), which gives it a dynamic edge, like a dancer pivoting effortlessly on a stage.
The A4, standard with Audi’s legendary Quattro all-wheel drive, prioritizes grip and stability, making it a steadfast companion in adverse conditions.
For example, imagine navigating a snowy Colorado mountain pass: the A4’s Quattro system distributes torque seamlessly, ensuring confidence where the 3 Series might demand a defter touch.
A 2024 study by MotorTrend found that the BMW M340i and Audi S4 both hit 0-60 mph in 4.2 seconds, proving their performance credentials are neck-and-neck.
Yet, the BMW’s sharper steering and more responsive chassis make it the enthusiast’s choice for winding roads, while the A4’s smoother power delivery suits those prioritizing refinement over raw athleticism.

Driving Dynamics: The Art of the Journey
Beyond raw power, the BMW 3 Series vs Audi A4 comparison hinges on how these sedans feel behind the wheel.
The BMW 3 Series is the quintessential driver’s car, with a chassis tuned for agility and feedback.
Its steering is razor-sharp, offering a tactile connection to the road, akin to a painter wielding a fine brush.
On a twisty backroad in California’s Napa Valley, the 3 Series dances through corners with poise, rewarding drivers who revel in precision.
Conversely, the Audi A4 leans toward composure.
Its suspension soaks up imperfections with a grace that makes long highway drives feel like gliding on a cloud.
The Quattro system ensures unwavering traction, but the A4’s steering, while accurate, lacks the BMW’s immediacy.
For instance, merging onto a bustling Los Angeles freeway, the A4’s smooth power delivery and stable handling inspire confidence, even in heavy traffic.
Why choose between thrill and comfort?
The BMW 3 Series vs Audi A4 forces you to decide: do you crave the adrenaline of a spirited drive or the serenity of a refined cruiser?
The answer depends on your driving soul.
A test drive is crucial to experiencing these differences firsthand and determining which sedan aligns with your preferences.

Interior: Where Luxury Lives
Step inside, and both sedans envelop you in opulence, but their approaches differ.
The BMW 3 Series cockpit is driver-centric, with a dashboard angled toward the pilot, exuding a sporty vibe.
Premium materials like open-pore wood and aluminum tetragon accents elevate the ambiance, while the iDrive 8.5 system, displayed on a 14.9-inch curved touchscreen, is intuitive and responsive.
However, some critics note that the 3 Series’ interior can feel austere compared to its rivals, with fewer flourishes.
The Audi A4, by contrast, embraces minimalism with a futuristic edge.
Its Virtual Cockpit, a 12.3-inch digital gauge cluster, is a technological marvel, offering customizable displays that dazzle the senses.
The cabin’s clean lines, accented by oak or walnut inlays, create a serene environment.
For example, on a cross-country road trip, the A4’s quiet, well-insulated cabin and ergonomic seats make long hours behind the wheel a pleasure.
A key differentiator is space.
The BMW 3 Series offers a 17-cubic-foot trunk, outpacing the A4’s 12-cubic-foot capacity, making it the better choice for weekend getaways with luggage in tow.
Yet, the A4’s slightly roomier front cabin feels less confining for taller drivers.

The 3 Series also offers a head-up display and semi-autonomous driving aids, like adaptive cruise control with lane-keeping assist, enhancing safety on long drives.

The Virtual Cockpit remains a standout, offering navigation maps that fill the gauge cluster for a futuristic driving experience.
Audi’s suite of driver assists, including standard adaptive cruise control on higher trims, matches the BMW’s capabilities but feels more polished in execution.

Price is a critical factor in the BMW 3 Series vs Audi A4 debate.
The 2025 Audi A4 starts at $42,000, undercutting the 3 Series’ $44,500 base price.
However, fully loaded models like the A4 Prestige and 3 Series M340i xDrive can climb past $60,000.
The A4’s standard all-wheel drive adds value for buyers in colder climates, while the 3 Series’ rear-wheel-drive base model appeals to purists seeking lower upfront costs.
Fuel economy slightly favors the BMW, with the 330i achieving 26/36 mpg city/highway compared to the A4’s 24/33 mpg.
For eco-conscious buyers, the BMW 330e plug-in hybrid offers up to 37 miles of electric range, a feature Audi lacks in the A4 lineup.
Maintenance costs are comparable, but BMW’s xDrive system is noted for being slightly more responsive than Audi’s Quattro in dynamic scenarios, potentially reducing wear on tires in spirited driving.
