It’s an A4. I may have designated it incorrectly, but in about 2012 Audi started putting what they call “Dynamic Adaptive Steering” into the A4s and some other models. This actually alters the steering ratio in accordance with the speed you’re going. Sounds cool, but in reality it leads to a spongy type of steering that sometimes makes you feel like it is YOU who is doing the dynamic adapting. Just another example of how ‘better’ can be the enemy of good.
