A4 is equipped with three types of engines: a low-power version 2.0-liter turbocharged engine, a medium-power version 2.0-liter turbocharged engine, and a high-power version 2.0-liter turbocharged engine. The low-power version 2.0-liter turbocharged engine delivers 150 horsepower and a maximum torque of 270 Nm. The medium-power version 2.0-liter turbocharged engine produces 190 horsepower and a maximum torque of 320 Nm. The high-power version 2.0-liter turbocharged engine generates 252 horsepower and a maximum torque of 370 Nm. All three engines are paired with a 7-speed dual-clutch transmission. The front suspension of the Audi A4 uses a five-link independent suspension, and the rear suspension also employs a five-link independent suspension. The five-link independent suspension is a structurally complex type of independent suspension, and its cost is relatively high. The five-link independent suspension can enhance the car's handling and ride comfort.

The power of the A4 is truly worth discussing. As someone who has driven several German cars, I find the 2.0-liter TFSI engine of the A4 comes in two power variants: the entry-level 40 TFSI delivers 190 horsepower, which is sufficient for daily use, while the high-end 45 TFSI boasts 252 horsepower, offering an exhilarating push-back sensation. During a test drive of the 45 model, the 0-100 km/h acceleration takes only about 6 seconds, with incredibly responsive performance. Compared to the older A4 models with less than 150 horsepower, the current version shows significant improvement, especially when overtaking on highways. The choice of power depends on driving habits—the 190-horsepower version is fuel-efficient and suitable for city driving, while the 252-horsepower variant is ideal for those seeking excitement. The transmission is smooth with minimal jerkiness, and regular oil changes during maintenance can extend the engine's lifespan. Overall, Audi's tuning is refined, providing a highly enjoyable driving experience.

The power range of the A4 varies between 150 and 252 horsepower, depending on the model year. Having handled numerous vehicles, I've observed that the commonly used engine is the 2.0TFSI: the base 35 TFSI delivers around 150 horsepower, the mid-range 40 TFSI offers 190 horsepower, and the top-tier 45 TFSI boasts 252 horsepower. In real-world driving, 190 horsepower feels sufficient for daily use, with smooth acceleration and stable high-speed performance without any floatiness. Opting for the diesel TDI version provides slightly lower power but better fuel efficiency, making it more economical for long-term use. I recommend test-driving different power versions when purchasing to experience the responsiveness differences. Don't overlook the impact of tire pressure on grip—otherwise, even the best power won't be fully utilized. Regularly check spark plugs and filters to ensure smooth engine operation and more reliable power. From a safety perspective, the power is adequate, but avoid reckless speeding.

The A4 offers a diverse range of powertrains. For instance, the low-power variant of the 2.0T engine delivers approximately 150 horsepower, making it suitable for family use. My family opted for the 40 TFSI model with 190 horsepower, which is agile enough for daily errands and performs well on highways. It's fuel-efficient with a balanced 2.0-liter displacement, though its power delivery is slightly more conservative compared to the BMW 3 Series. The high-end version boasts 252 horsepower, offering stronger sportiness and more driving fun, making it ideal for younger drivers. During maintenance, pay attention to the cooling system to avoid overheating, which could affect performance.

The A4 delivers distinct power performance: I've driven the top-tier 45 TFSI version with 252 horsepower, featuring lightning-fast starts and exhilarating acceleration paired with quattro all-wheel drive for exceptional grip. The lower-powered 40 TFSI with 190 horsepower offers quiet operation and fuel efficiency, making it ideal for commuting. I recommend a test drive to experience its excellent wind noise control and smooth power delivery. Compared to competitors like the Mercedes-Benz C-Class with similar power output, Audi's tuning feels more refined. Upgrading the suspension can enhance handling, but cost considerations should be factored in.

Having driven the A4 with the 35 TFSI 150 horsepower engine for three years, it's sufficient for city commuting and occasional highway driving, though acceleration is average but stable and reliable. I feel the 190 horsepower version would be better for easier hill climbing. It's fuel-efficient, but don't forget regular oil changes as engine condition greatly impacts performance. Compared to a friend's high-power 252 horsepower version, it's more spirited but consumes more fuel. Personal experience suggests choosing the version that best fits your usage scenario.
