A week ago, driving home from Atlantic City, I reset the trip computer stuff when I got to the Parkway. Checked when I got off: average speed (54 miles): 83.1 mph. Gas mileage (crosschecked): 25-26 mpg. Modest tail wind.
Two days later I was on the same route, and we got fresh hard-packed snow. I couldn't keep up with friggin' minivans on my OEM treads Average speed: 28 mph. Gas mileage -- hell, I would've poured it on the road if it would have helped the Z stick. This is not a winter-driving car.
