Understanding the Audi A4 40 TDI
The "40 TDI" designation in Audi's nomenclature typically refers to a specific power output range for their diesel engines. In the case of the Audi A4, the 40 TDI is equipped with a 2.0-liter four-cylinder turbocharged diesel engine. This powerplant is highly regarded for its robust performance and commendable fuel efficiency.
Engine and Performance Specifications

This allows for brisk acceleration, with 0-62 mph times ranging from 6.9 to 7.7 seconds, depending on the specific model year and configuration (e.g., saloon vs. Avant, Quattro vs. FWD). The engine is paired with a slick 7-speed S Tronic dual-clutch automatic gearbox as standard, ensuring smooth and rapid gear changes. While diesel engines can sometimes be perceived as noisy, reviews highlight the A4 40 TDI's incredibly quiet cabin, even under hard acceleration, making it a refined cruiser on motorways.
Key Performance Metrics:

- Horsepower: 201-204 bhp (150 kW)
- Torque: 400 Nm (295 ft-lb)
- 0-62 mph: 6.9 - 7.7 seconds
- Top Speed: Approximately 150 mph
- Transmission: 7-speed S Tronic dual-clutch automatic
Fuel Efficiency and Emissions
Despite its performance, the 40 TDI is also designed for efficiency. Fuel consumption figures typically range from 4.9-8.4 l/100 km (equivalent to 28-48 mpg US / 34-58 mpg UK). CO2 emissions are generally in the range of 130-179 g/km, which is important for understanding running costs, especially regarding company car tax and road tax in certain regions.
Driving Experience and Handling
The Audi A4, particularly the 40 TDI variant, is lauded for its sophisticated driving dynamics. It strikes a compelling balance between comfort and sportiness, making it suitable for both daily commuting and longer journeys.
Ride Comfort and Refinement
The A4's interior is renowned for its quietness and comfort. Even with sportier trims like S Line, which might include lowered suspension and larger wheels, the ride quality remains remarkably composed. Reviewers often note that the A4's suspension manages to absorb road imperfections effectively, providing a plush experience without feeling overly soft. The well-crafted cabin contributes significantly to this refinement, with high-quality materials and excellent build.

Steering and Handling
The A4 offers precise steering and strong road-holding capabilities. Models equipped with Audi's Quattro all-wheel drive system provide enhanced grip and stability, making the car feel particularly unflappable in corners and adverse weather conditions. While some compare its driving dynamics to the BMW 3 Series, often noting the BMW is slightly more agile, the A4 prioritizes composure and confidence, which many drivers prefer for everyday use.
The configurable Drive Select system, standard in many A4 models, allows drivers to alter steering feel, throttle response, and other factors across modes like Comfort, Auto, Efficiency, and Dynamic, catering to different driving preferences.
Interior, Technology, and Practicality
Audi's reputation for high-quality interiors is evident in the A4. The cabin is thoughtfully designed, offering a blend of aesthetics, functionality, and advanced technology.
Cabin Quality and Design
The A4's interior is consistently praised for its premium feel, with exemplary material quality and assembly. Standard features often include leather upholstery and wood trim, contributing to an upscale ambiance. The layout is logical and driver-focused, with controls intuitively placed.
Practicality is also a strong suit. The A4 offers ample space for front and rear passengers, though the middle seat in the rear might be less comfortable due to the transmission tunnel. The Avant (estate) version significantly enhances cargo space, making it a versatile family car that rivals many SUVs in utility.
Infotainment and Driver Assistance
Modern Audi A4 models feature excellent digital dashboard displays, often replacing traditional analogue dials, which are configurable to show various information like navigation, audio, and driving data. The infotainment system typically includes a large touchscreen with Apple CarPlay and Android Auto compatibility. Advanced driver-assistance features are standard, including lane-keep assist, adaptive cruise control, and automatic high-beam headlights, with options for blind-spot monitors and a surround-view camera.
Value Proposition and Model Year Considerations
Determining the "best value" for an Audi A4 40 TDI depends on whether you're looking for new or used, and what specific features are prioritized.
New vs. Used Audi A4 40 TDI
For new car buyers, the 2025 Audi A4, while still a strong contender, is in its final model year before being replaced by the A5, with Audi planning to reserve even numbers for electric cars. Pricing for new 2025 A4 models starts around $45,395 and can go up to $52,595 for higher trims like the S line 45 TFSI Prestige. Opting for the S line Premium Plus trim is often recommended as the best overall value for new models due to its enhanced features and more powerful engine option.
For used car buyers, the Audi A4 offers excellent value, particularly diesel variants which tend to be more economical. While some suggest older models like the 2014-2016 (B8 generation) as having had their bugs worked out, the B9 generation (2015-present) is also a strong choice due to its refined nature and updated technology. The 2018-2019 models are often cited as offering the best value for money in the used market. Used A4s can be found starting from around $16,500 for older models, with average costs around $35,424 depending on factors like service history and mileage.
Trim Levels and Their Impact on Value
Audi offers various trim levels for the A4, such as Sport, S Line, Technik, Black Edition, and Vorsprung. The Sport trim is well-equipped, but the S Line typically offers a more aggressive aesthetic with body kits, bigger alloy wheels, and sportier interior elements like enhanced seats. While S Line often comes with lowered suspension, which some might find firmer, reviews generally indicate that the ride remains comfortable. For a company car, the 40 TDI Quattro Sport is often recommended over the 35 TDI S Line due to its increased power, assuming features like bodykits and larger alloys are not the primary drivers for choice.

Reliability and Ownership
The Audi A4 generally has an average predicted reliability score, with J.D. Power rating the 2025 A4 at 73 out of 100. While some reports mention potential issues with technology, engines, and suspension, many owners report having their vehicles for years without problems, especially if well-maintained. The A4 has a strong fan base due to its driving dynamics and the enduring quality of its virtual cockpit and other technologies.
Comparative Analysis: Audi A4 40 TDI in the Luxury Segment
The Audi A4 competes fiercely with established rivals like the BMW 3 Series and Mercedes-Benz C-Class. While these competitors might offer more flamboyant designs or higher standard horsepower in some configurations, the A4 distinguishes itself with its balanced approach.
A4 40 TDI vs. Competitors
When compared to the BMW 320d and Mercedes C220d, the Audi A4 40 TDI offers a compelling package. It is often praised for its superior interior quality and technology integration. While the BMW 3 Series might be seen as slightly more driver-focused with its handling, the A4 excels in refinement and comfort.
In terms of value, the A4 is generally competitive with its premium rivals. While it might be more expensive than non-premium cars like the Skoda Superb, it often undercuts the BMW 3 Series and Mercedes C-Class on initial purchase price. However, resale values for the A4 are not always as strong as its key German rivals, which can impact PCP finance rates.
