I picked up my S60 yesterday in Atlanta and I was worried about the drive home from Atlanta to Hoover, Al due to both evtripping.com and evtripplanner.com stating that I'd get home with only 28-35 miles remaining if I drive at or below the speed limit. After making that trip, I'm seriously questioning the accuracy of those two websites. I topped off to 210 miles at the Atlantic Station charger and then started the trip home. It was rush hour and the interstates were dead still. So I cut through town and hopped on I-20 from "Hamilton E Homes Dr NW". I had already called and arranged to charge at a nissan dealership located about halfway through the trip. So I didn't bother driving slow like the trip planners suggested. I set the cruise control on 77 since that was what traffic was moving at and just kept an eye on the charge level. When I got close to the Nissan dealership I noticed that I still had about 65% of the battery left. So I decided to just skip charging. I ended up making it home with 52 miles remaining with the cruise set at 77 and even bumping it up to 80 at times. Are the trip planning sites that inaccurate in general or is there a difference in the older S60 and new S60 that they don't account for?
