City gas mileage for the new 4-cylinder Camry is listed as 21 mpg. However, in fine print the sticker says that actual mileage can be anywhere between something like 17 - 23 (I forget the exact numbers). Is this range of mpg due to the different driving conditions that may be encountered, or does it refer to variability in the inherent fuel economy of the car from one sample to the next?
This potential purchase will be replacing our big minivan that gets about 16-17 mpg around town (suburbs) and I would be very disappointed if I bought the relatively smaller Camry and ended up getting 17 mpg again in those same driving conditions.
Thanks.
