Quick answer: The 2025 Audi A4 starts at $45,395 for the Premium 45 TFSI trim, reflecting the deletion of the lower-output 40 TFSI powertrain. This final model year of the B9 generation features standard quattro all-wheel drive, a 261-horsepower engine, and minor upgrades like standard remote engine start via the myAudi app.
Key takeaways:
The 2025 Audi A4 marks the final production run of the B9 generation, which originally debuted in the United States for the 2017 model year. Assembled at Audi's primary manufacturing facility in Ingolstadt, Germany (as documented in the production history of the Audi A4), this platform is retiring to make way for the new Premium Platform Combustion architecture. This transition brings an end to a highly successful era for the brand's compact executive sedan. Over its nine-year run, this generation established itself as a benchmark for interior build quality and refined road manners in its class.
During its multi-year lifecycle, the B9 platform introduced several key technological advancements to the entry-luxury segment. These included the widespread adoption of the Audi Virtual Cockpit digital gauge display, standard all-wheel-drive configurations for high-output models, and the integration of mild-hybrid electrical architectures to optimize efficiency. These steady improvements have kept the vehicle competitive against newer designs. For those shopping the pre-owned market, reviewing previous generations such as the 2018 Audi A4 review can reveal how these chassis and powertrain updates evolved from the initial 2017 Audi A4 launch.
For its final production cycle, the 2025 model year introduces high-value standard features to streamline the ordering process. The most notable additions are standard remote engine start capability and rear-seat USB charging ports. By packaging these options into the base specification, Audi increases the retail appeal of the sedan as it enters its final sales cycle. These adjustments represent a direct effort to maintain sales momentum without launching expensive sheet-metal redesigns before the successor model arrives.
The remote engine start system operates via the myAudi smartphone application. This technology allows owners to start the engine, set the cabin temperature, and activate defrost systems remotely. Additionally, the mid-tier Premium Plus trim level receives the MMI Navigation plus package as standard equipment. This package includes real-time traffic updates, navigation mapping within the digital instrument cluster, and expanded connect services, features that previously required separate option packages.
A comparison between the 2025 and 2024 model years highlights a simplified packaging layout where the 45 TFSI powertrain becomes the standard setup. While the base entry price appears higher for the newer model year, the value is offset by the addition of standard equipment. This powertrain consolidation eliminates the previous base 40 TFSI configuration, which generated 201 horsepower and 236 lb-ft of torque.
This change shifts the value proposition for entry-level buyers. In previous model years, budget-conscious consumers could choose the lower-powered engine to save on purchase costs. For 2025, every buyer receives the sportier performance setup as standard. When examining the base configurations side-by-side, the new standard equipment list represents a significant upgrade over the older base layouts. For detailed specifications of previous iterations, reviewing the 2024 Audi A4 used review can provide valuable historical context.

The 2025 model is powered by the EA888 2.0-liter turbocharged four-cylinder engine tuned to the 45 TFSI specification. This engine produces 261 horsepower and 273 lb-ft of torque, representing a significant output increase over the discontinued base engine. Power is sent through a seven-speed S tronic dual-clutch automatic transmission and standard quattro all-wheel drive. In independent testing, this drivetrain propels the sedan from 0 to 60 mph in 5.2 seconds, delivering strong passing power.
The standard quattro all-wheel-drive system uses ultra technology to improve efficiency. This setup monitors driving conditions and can completely decouple the rear driveshaft when cruising on dry highways, reducing friction and fuel consumption. The system can re-engage the rear axle in less than 250 milliseconds when it detects wheel slip, hard cornering, or sudden throttle inputs. The mild-hybrid system uses a 12-volt alternator-starter to smooth out the automatic stop-start cycles, though it does not propel the vehicle under electric power alone.
| Specification | 45 TFSI Powertrain Value |
|---|---|
| Engine Type | Turbocharged 2.0-liter 4-cylinder (EA888) |
| Horsepower | 261 hp @ 5,000-6,000 rpm |
| Torque | 273 lb-ft @ 1,600-4,000 rpm |
| Transmission | 7-speed S tronic dual-clutch automatic |
| Drivetrain | quattro with ultra technology (AWD) |

The 2025 model achieves EPA-estimated fuel economy ratings of 23 mpg city, 32 mpg highway, and 26 mpg combined. Supported by a 15.3-gallon fuel tank, the sedan delivers a maximum highway range of approximately 489 miles under normal highway driving conditions. These efficiency ratings are competitive for an all-wheel-drive luxury sedan, aided by the drag-reduction features of the ultra-equipped quattro system.
In real-world highway driving, the vehicle often matches or exceeds its EPA highway rating. The transmission is geared to keep engine speeds low during highway cruising, which helps save fuel on long trips. Additionally, the automatic coasting feature decouples the engine from the transmission when descending slight highway grades, reducing internal friction losses and conserving momentum.
The pricing structure for the 2025 model begins at $45,395 for the Premium trim, rises to $49,895 for the Premium Plus, and tops out at $52,595 for the Prestige. All pricing includes the standard $1,295 destination and delivery charge, reflecting the simplified single-engine lineup. This transparent pricing structure helps buyers evaluate the real transactional costs, as confirmed in the official Audi USA 2025 product announcement.
The trim progression follows a traditional structure. The base Premium trim offers leather seating surfaces, heated front seats, three-zone automatic climate control, and a power sunroof. The Premium Plus adds key tech upgrades, such as the Virtual Cockpit digital instrument cluster, wireless phone charging, and a top-view camera system. The range-topping Prestige trim adds high-end luxury items, including matrix-design LED headlights, ventilated front seats, and a head-up display. More details on the broader Audi A4 buyer guide are available for comparing features across different configuration packages.

| Premium Plus | $48,600 | $1,295 | $49,895 |
| Prestige | $51,300 | $1,295 | $52,595 |
The new S line plus package is available for the 2025 model year, priced at $2,350. Offered on the Premium Plus and Prestige trims, it replaces separate cosmetic options with a single, sport-focused appearance group. This package gives the sedan a more aggressive look for its final model year, appealing to brand enthusiasts.
This styling upgrade features blacked-out exterior trim that covers the window surrounds, front grille frame, and side sill details. The package also adds red-painted brake calipers, RS carbon fiber dashboard accents, stainless steel pedal caps, and 19-inch bi-color wheels wrapped in summer performance tires. These details help distinguish the final production run from earlier model years.
For buyers seeking more speed or utility, the high-performance S4 and A4 Allroad wagon continue to be offered alongside the standard sedan. The S4, often highlighted in discussions about the best Audi sports cars, uses a 3.0-liter turbocharged V6 engine that generates 349 horsepower and 369 lb-ft of torque, pushing the sports sedan from 0 to 60 mph in 4.4 seconds. Unlike the standard sedan, the S4 uses an eight-speed torque-converter automatic transmission to handle the V6's high torque output. The S4 starts at $56,195, including the $1,295 destination charge.
The A4 Allroad wagon features a raised suspension with 6.5 inches of ground clearance, plastic body cladding to protect against stone chips, and 58.5 cubic feet of maximum cargo space with the rear seats folded. It offers a comfortable alternative to compact crossover SUVs, combining car-like handling with cargo flexibility. The A4 Allroad starts at $48,895, including the $1,295 destination charge.
In 2026, the combustion-powered model will transition to the A5 nameplate to align with Audi's new naming convention. Under this strategy, odd numbers designate gas models, and even numbers represent electric vehicles. The upcoming successor will adopt a liftback configuration on the new Premium Platform Combustion architecture, which means the traditional three-box sedan layout is being retired.
This strategy helps the brand reserve even numbers for its expanding line of e-tron electric vehicles, including high-performance models like the Audi e-tron GT. The upcoming 2026 successor will grow in size, measuring 2.6 inches longer with a 2.7-inch longer wheelbase compared to the outgoing B9 model. This growth addresses a common customer complaint: limited rear-seat legroom. The shift to a liftback body style also increases cargo flexibility, combining the profile of a sedan with the hatch utility of a sportback.
The 2025 model represents a highly rational purchase for buyers prioritizing proven reliability and transactional discounts over the latest dashboard styling. Because the B9 platform has been in production for nearly a decade, most mechanical bugs have been resolved, making this final-year car a durable option. This maturity directly impacts longevity, aligning with broader findings on how many miles Audis typically last under consistent maintenance schedules. However, its small 12-cubic-foot trunk and aging dashboard screens make it less suitable for buyers wanting the latest screen setups.
Financially, buying a final-year model offers advantages. Dealerships are motivated to clear out old inventory before the redesigned successor arrives, resulting in average discounts of $2,500 to $3,500 off MSRP. However, the dashboard screens look small compared to newer competitors, and the rear seat remains cramped for taller adults. Buyers must decide if the discounts and proven reliability outweigh the older cabin design.
Expert view: The final year of the B9 platform represents the peak of its reliability curve. Buyers can negotiate significant discounts on a mature, proven vehicle, making it a smarter financial choice than waiting for the unproven and more expensive successor model.
The 2025 model competes against the BMW 3 Series, Mercedes-Benz C-Class, and Genesis G70. While the Audi undercuts German rivals on entry price and offers standard all-wheel drive, it lags behind in infotainment scale and rear passenger space. Ripping through corners shows that the BMW 3 Series remains the sharper driver's car, while the Mercedes-Benz C-Class offers a more dramatic interior design.
The biggest competitive advantage for the A4 is its pricing when all-wheel drive is included. The base BMW 330i starts at a higher MSRP before adding xDrive, and the Mercedes C300 requires a similar premium for 4MATIC. This makes the A4 a strong value play. However, the Genesis G70 offers a longer 10-year warranty, which may appeal to long-term owners. The A4 sits in the middle, offering a balanced, sensible cabin layout with high-quality interior materials.
| Specification | 2025 Audi A4 45 TFSI | 2025 BMW 330i xDrive | 2025 Mercedes C300 4MATIC |
|---|---|---|---|
| Starting MSRP (with destination) | $45,395 | $49,850 | $51,600 |
| Standard Horsepower | 261 hp | 255 hp | 255 hp |
| All-Wheel Drive | Standard | Standard | Standard |
| Trunk Volume | 12.0 cu ft | 17.0 cu ft | 12.6 cu ft |
Note: Price comparisons must account for standard all-wheel drive. While competitors may advertise lower base prices, adding all-wheel drive to BMW or Mercedes models often pushes their price $2,000 higher than the Audi.
