Hi buddies. I wonder if one could say... Мы (целый) день проезжали тысячу километров!

[va-diim]

This doesn't sound natural. It sounds like "We were driving by [as in 'passing by'] a thousand kilometers the whole day."

[PaxBorealis]

Still possible, though. Like in a distant future with light speeds and stuff, when they have their rocket car broken and they spend as much as a whole day to drive for as little as one thousand kilometers.

Translation should be 'per day' not 'in a day'

[va-diim]

1000 km per day implies multiple days of travel. That would be 1000 км в день. That's a different meaning than 1000 km in a day or for the day which is за день
