Honestly this is absurd. These death machines shouldn’t be legal in europe. That thing doesn’t even fit in the parking space, even though the parking lot has the biggest spaces in the whole city. The Golf Polo is so small in comparison, it could even hide in front of the engine hood of the truck.
EDIT: It’s a Polo and not a Golf, I don’t know my cars, sorry for that!
Just do a little bit of research into the fuel efficiency of various sized vehicles, the correlation is not direct and some larger vehicles get better gas mileage than smaller vehicles strictly due to efficiency. A small inefficient motor and a large efficient motor may yield the same mpg, but the large efficient motor is extracting more power from the same fuel source. And that’s not even getting into diesel versus gasoline…
Some being they key word here. Those specific vehicles were built with effency in mind. Now take the Ford F150 being the most common truck in Canada / USeh and I’d bet not a single one will be more efficient than a 6 cylinder AWD car. Your argument is kinda moot as your looking at outliers.
