1SmartB - I took I-580 from San Mateo out to Stockton and I-5 up to Sacramento last week during the same rough weather system, and we hit 45+ head winds all the way. I had two in the car plus luggage and the A/C on to keep out the dust and dirt, BUT I tried to keep my speed down to 65 to 70 mph. I got 43.5 mpg for the trip. So, the speed seems to be the big difference. A few days later, only one person in the car, no winds, no A/C and same speed along I-80, and I got 53.4 mpg. Hope that helps.Thanks for the replies. I look forward to buzzing around in my smart and still getting 30mpg. I just calculated the mileage from our mother's day trip and we got 35mpg all freeway, that was in windy conditions with the car loaded with us and the dog, and doing 80mph. We were squirming around quite a bit in the wind and actually had to slow down a couple of times to keep from sailing off the road.
I think when the smarts are getting 25, the guzzlers are getting 12.Wow as low as 21 in SF! 25 in NYC! Maybe it's NOT such a great city car afterall!
21. Hilly San Francisco kills it hard.. and that was b-a-b-y-i-n-g it.. driving it as if there was an egg btw my foot and the pedal. The car's also had some significant mechanical issues, so maybe that was affecting it.
