I am unsure if my numbers are correct but from what I see online, the G70 has 130mm of ground clearance, I believe the RWD ones are a tad lower, and the S4 has 120mm. But it may be different ways to measure or something.Ground clearance is a problem in my S4, which is about an inch higher than the G70. (At least the Sport G70 I measured at the car show). Quattro traction is great, but big chunks of ice on the road beats up the bottom of the car and front plastics. Deep snow turns the car into a snow plow.
