Q&A for How to Determine if Your Car Is Front or Rear Wheel Drive

Yes, but you have to have the front wheels on the ground and rear ones off the ground.

The easiest way would be to type all the information about your car into Google (make, model, year, etc.). You should be able to find out that way if your car has 4WD that way. You could also check your owner's manual.

All generations of the A6 have offered either front-wheel drive or Torsen-based four-wheel drive, marketed by Audi as their quattro system. Second- and third-generation A6 models have shared their platform with the company's Allroad models.

Aside from reading the owner's manual or doing an internet search on the specific vehicle to check the specs, the easiest way is to place the vehicle on a flat-but-slippery surface (ice, mud, wet grass or gravel) and have a friend watch the wheels while standing away from and on the car's side as you accelerate. The wheel that spins on the ice or grass is the one that indicates whether you have front or rear wheel drive.
