>an extra 40kgs of weight in the car which costs a bit. Do European cars have gigantic fuel tanks? 40kgs is 40 / 0.71kg/L = 56.3L ~= 14.9 gallons. 14.9 gallons is as much, or more than any car I own carries. And I've never put more than 13 gallons into any vehicle ever during a single fill up. To have that kind of "spare" capacity beyond what would be necessary for my daily commute, I'd need to be driving a large SUV or pickup truck. I looked up a 3 Series BMW, and they have 40L or 57L tanks in the new models. Down from 60 or so 10 years ago. I feel like 20kgs is a more accurate number. And that's really the difference between a small woman and a medium sized man driving the same vehicle.
