Domestic A6 is not four-wheel drive, it retains the old Torsen C-type differential. Four-wheel drive refers to a vehicle maintaining four-wheel drive throughout the entire driving process, with the engine's torque distributed to the front and rear wheels in a fixed ratio. This driving mode ensures good off-road and handling performance at all times, but cannot adjust torque distribution based on road conditions. The A6 is a luxury car produced by Audi, available in both sedan and wagon models. In terms of body dimensions, it measures 5012mm in length, 1855mm in width, 1485mm in height, with a wheelbase of 2945mm.

I'm really into studying the details of cars, and the domestically produced Audi A6L indeed offers a four-wheel-drive version, especially in high-end models like the 50TFSI, which comes with Audi's classic Quattro system. This four-wheel-drive system is truly impressive, providing exceptional grip and stability, making it safer in rainy or snowy conditions and during high-speed cornering, while also enhancing the driving experience. However, the four-wheel-drive models are more expensive, and their fuel consumption is slightly higher than the front-wheel-drive versions. For daily city commuting, it might not feel worth it. Audi's four-wheel-drive is very popular in the north, offering excellent anti-slip performance in winter, but in the south, front-wheel-drive is usually sufficient. A friend at a modification shop mentioned that four-wheel-drive maintenance is a bit more complex, requiring regular checks on the differential and drive shaft to avoid long-term neglect leading to wear. In short, if you have the need, the four-wheel-drive version is worth considering.

As someone who frequently works on car repairs, I've disassembled and reassembled many domestically produced Audi A6Ls, some of which are two-wheel drive while others are four-wheel drive. The four-wheel-drive version is structurally more complex, with additional components like front and rear axle transmission parts, leading to higher maintenance costs. Extra attention is needed when changing the oil, particularly to the gear oil. The advantage is its safety and reliability, especially on slippery roads where it prevents skidding, making it suitable for friends who often drive long distances or on mountain roads. However, for daily city driving, the front-wheel-drive version is simpler, more durable, has lower fuel consumption, and is cheaper, so there's no need to insist on the four-wheel-drive option. Choosing a car depends on the usage scenario. If the budget is tight or the car is just for commuting, the two-wheel-drive version is more cost-effective. If the climate is harsh or there are performance requirements, the four-wheel-drive A6L is indeed a good choice. Audi's overall build quality is solid, and the four-wheel-drive system is quite durable.

Our family just switched to a domestic A6L, opting for the front-wheel-drive version instead of the four-wheel-drive one. This Audi model comes with different configurations—some have four-wheel drive while others don't, with four-wheel drive mostly found in higher-end versions at a premium of tens of thousands of yuan. I think four-wheel drive offers more reliability in terms of safety, such as reducing the risk of skidding on rainy days or snowy roads. However, for an average family, front-wheel drive is more than sufficient and saves a lot on fuel consumption. For daily tasks like picking up and dropping off kids at school, driving smoothly in the city is completely fine. Considering cost-effectiveness is quite important when choosing a car—four-wheel drive may require slightly more maintenance costs but enhances comfort. The Audi brand is reliable; just choose based on your budget.
