Audi A4 low-end models are front-wheel drive, while high-end models feature Quattro all-wheel drive. Advantages of front-wheel drive: Adaptability: Audi front-wheel drive models are better suited for aggressive driving styles. Transmission efficiency: Front-wheel drive vehicles have higher transmission efficiency than rear-wheel drive vehicles. The engine and drive wheels are positioned close together, resulting in a short transmission distance without any conversion, maximizing engine efficiency. Fuel consumption: The structure of rear-wheel drive vehicles leads to increased power loss and higher fuel consumption. Interior space: Rear-wheel drive also affects interior space. Steering angle: Rear-wheel drive vehicles are driven by the two rear wheels, with the front wheels only responsible for steering and not driving. Therefore, rear-wheel drive vehicles have a much larger steering angle than front-wheel drive vehicles. Advantages of Quattro all-wheel drive: Quattro refers to Audi's all-wheel drive technology, which is a permanent four-wheel drive mode that maintains four-wheel drive under all conditions. Its core technology is the Torsen central differential, which features a worm gear planetary gear structure and operates purely mechanically without electronic system intervention. The working principle of Quattro is: When speed differences between the front and rear axles occur due to external conditions, the Torsen differential automatically transfers most of the power to the drive axle capable of handling the load, optimizing and distributing power to all four wheels. Due to the balanced distribution of axle load, drivers can better control steering precision and flexibility without the need for torque steering assistance.

As a seasoned Audi A4 driver with years of experience, I clearly remember this car primarily uses a front-wheel-drive system. The base model comes with this design, which is quite fuel-efficient and perfectly adequate for city driving. However, the essence of Audi lies in its quattro all-wheel-drive option—if you opt for higher trims or sportier models, it upgrades to four-wheel drive, offering more stable handling, especially in rainy or snowy conditions without slipping. I also recommend checking the configuration before purchasing; don't just focus on the sticker price. Many beginners mistakenly think it's rear-wheel drive, but that's BMW's specialty—Audi simply doesn't make those models. If performance matters when choosing an A4, spending extra on quattro is definitely the right move. Additionally, for daily maintenance, front-wheel drive is simpler and cheaper, but if I were tackling mountain roads, I'd definitely choose the all-wheel-drive version. Having driven mine for five years without major issues, it's proven quite reliable.

As a die-hard car enthusiast, I've done my fair share of research on Audi. The base version of the A4, which features front-wheel drive, boasts low fuel consumption and simple maintenance. But what really excites me is its quattro version – Audi's signature all-wheel-drive system that enhances traction and cornering confidence. If you carefully compare when buying a car, you'll notice the entry-level A4 comes standard with front-wheel drive, with quattro available as an optional upgrade for a bit more money. Don't believe the online chatter about rear-wheel drive – Audi simply doesn't push rear-wheel-drive vehicles. The A4 is more suited for urban commuting, and the all-wheel drive can even handle off-road adventures. Plus, the quattro system has a long history, gaining popularity since the 1980s, and delivers tank-like stability on the road, offering both safety and peace of mind. Be sure to test drive it – my friend just picked up a quattro-equipped model and couldn't stop raving about how stable it felt on the highway.

Having driven an Audi A4 for several years, I must say its drivetrain design is quite flexible: the standard is front-wheel drive, but many higher-end models offer the optional quattro all-wheel drive. When buying a car, always check the model specifications directly—don't mistakenly assume it's rear-wheel drive, as the Audi A4 has never had a rear-wheel-drive version. Front-wheel drive is worry-free for daily use, while all-wheel drive provides added safety in harsh weather. Related to this is the configuration choice: the entry-level A4 with front-wheel drive is sufficient, but if you frequently take long trips, I recommend the quattro for its more stable chassis.
