In terms of exterior design, the 2018 model features a single horizontal bar on the air intake grille below the headlights as part of its sporty surround, whereas the 2017 model has three horizontal bars. Here are the detailed related information: Introduction: The all-new A4L is equipped with a new 8-speed multitronic continuously variable/manual transmission, providing smoother gear shifts and more efficient power transmission, thereby enhancing driving comfort and fuel economy. Additionally, the latest generation quattro all-wheel-drive system is also installed in the Audi A4L. The 40:60 torque distribution allows drivers to enjoy a higher level of driving pleasure, while the close coordination with the ESP electronic stability program improves the active safety of the vehicle. Model: Due to the use of aluminum for many components in the redesigned chassis, the strength of the chassis is increased while the weight is reduced. The rear features smooth, full, and rounded lines, with a slightly upturned design on the trunk lid that helps stabilize the airflow at the rear during high-speed driving.

The main differences between the 2017, 2018, and 2019 A4L models lie in their exterior design, interior features, and technological upgrades. I remember driving these models—the 2017 version, as the initial B9 platform iteration, had a classic design but came with standard LED headlights. The 2018 model improved the front grille and added dynamic turn signals, making nighttime driving much cooler. The 2019 version saw more noticeable changes, with a sharper front fascia, an enlarged 10-inch interior screen, and a smoother operating interface.
In terms of powertrain, all three mostly used a 2.0T engine, but the 2018 model optimized transmission response for smoother gear shifts. The 2019 version fine-tuned fuel efficiency controls, resulting in slightly lower overall fuel consumption. Technologically, the 2018 model enhanced driving assistance features like basic adaptive cruise control, while the 2019 version added standard blind-spot monitoring for greater practicality.
Overall, while the generational updates were incremental, the cumulative improvements were significant. The 2019 model delivers a stronger tech feel, a more hassle-free driving experience, and retains the spacious cabin.

As someone who frequently works with these cars, the 2017 A4L has a solid foundation, equipped with the EA888 Gen3 engine, and features a stiffer suspension for direct handling, though it can feel bumpy at times. The 2018 model highlights upgrades in electronic systems, such as optimized lighting control modules, resulting in fewer fault codes during . The 2019 version improved the infotainment master control unit, significantly enhancing touch response. Additionally, the 2018 model transitioned from China V to China VI emission standards, while the 2019 model fully complies with China VI, requiring attention to fuel selection during maintenance. The body dimensions remain unchanged across all three models, but the 2019 version features softer interior materials and more comfortable seats. All models drive steadily, but the minor refinements in the 2018 and 2019 models make driving more refined, effortlessly handling urban commutes.

From a household perspective, I drove a 2017 A4L for several years—spacious enough with decent fuel consumption. The 2018 model mainly upgraded the air conditioning system, cooling faster and chilling the cabin quickly in summer. The 2019 version focused on safety enhancements, adding radar warnings and more responsive parking assistance. Power-wise, all three share similar 2.0T engines, sufficient for daily use, with comparable steering. Exterior tweaks: the 2018 model introduced new wheel designs, while the 2019 sharpened front bumper lines. Interior saw minor updates, with slight upgrades to seat materials. Pricing-wise, used 2017 models are cheaper, but the 2019 holds better long-term value; costs remain similar without extra expenses.

Comparing these models, the biggest evolution lies in the technological feel. The 2017 version introduced the first-generation virtual cockpit, cool but with slow response; the 2018 upgrade to a touchscreen made it smoother; the 2019 might support Apple CarPlay wireless connection, making navigation more convenient. Exterior lighting changes: the 2018 added dynamic effects, while the 2019 has a more modern design. Powertrain adjustments were minor, with the 2018 optimizing transmission logic for smoother acceleration; the 2019 slightly reduced weight to improve efficiency. Safety assistance features expanded from basic functions in the 2018 to standard full-speed cruise assist in the 2019. The space remains the same, offering high comfort with no hassle.

From a practical standpoint, purchasing a used 2017 A4L is cost-effective, with sufficient basic configurations and simple . The 2018 model highlights detailed upgrades such as easily replaceable headlight components and slightly better interior noise insulation, making it quieter on highways. The 2019 version enhances value for money, featuring standard safety equipment like automatic braking, making it suitable for families; the powertrain remains largely unchanged, but better emission compliance saves money in the long run. Exterior differences are minor, with less front grille chrome; the interior screen is larger but not the latest. Overall, the cabin space is similar across all three models, all suitable for city commuting, with stable maintenance costs of around 800 yuan per service.
