Apart from Up, the other two models you listed are for the above-average-middle-class-people, so to speak, at least in Europe. Most of the car-owners in Europe drive hatchbacks like Opel Corsa (average weight 1200 kg) or Skoda Fabia (average weight 1100 kg).
I agree that cars are very heavy now, though, usually there are few 'types' of car weight. I do not know which where is used.
Usually there are 2 weights: unladen weight and maximum weight. I've heard about some third weight which is between the unladen and maximum weights, something like a car's weight with full tank and a driver, but don't quote me on this.
Probably you have the maximum weight listed. My Skoda Fabia (Audi Q3 equivalent) has maximum weight of 1680kg and unladen weight of 1200kg. I refuse to believe that VW Up is heavier than the Skoda Fabia.
AFAIK, minivans have quite big weight on their papers, but empty minivan can't weigh 3000kg, which is only possible if it's loaded.
My old '89 Chevy S-10 weighed just over 1700 pounds (770 kg) empty. At 55 MPH (90 kph) on the freeway (back when that was still the limit), it got about 30 MPG (13 km/l / 7.7l/100km). OK, not great mileage, but what do you want for 80s US car tech :-)
For safety reasons, or whatever, they don't make mini trucks in the US any more. I did a double take on a new Dodge "Dakota" in the store parking lot the other day. It looked just like a full size pickup as far as I could see.
It wasn't for safety. Compact trucks have too small of a footprint to get away with the CAFE requirements for their size so manufacturers either supersize them (Dakota) or eliminate them altogether (Ranger).
Audi Q5 weights 1850 kg according to wikipedia (https://en.wikipedia.org/wiki/Audi_Q5), although this obviously depends on the engine. 2470 kg looks more like maximum allowed weight of car + passengers + cargo.
Yeah, I checked for the Polo, empty weight appears to be 1050 kg. The Golf TDI was a '96, so given the trends I expect it to be roughly similar. The original Golf I was under a ton.
