One practical way into this question is to think about where the word "Volvo" is most familiar from today, the car brand, and ask what idea a car company would want to build its name around.
A car's wheels are its most basic feature, and "rolling" is exactly the motion a wheel makes. The Latin verb behind the brand name, "volvere," means "to roll" or "to turn," and "Volvo" is simply its "I" form, "I roll." This same root shows up in other English words describing turning or rolling motion, such as "revolve," meaning to roll or turn around a center, and "evolve," meaning to unfold or turn out gradually over time.
None of "running," "leaping," or "jumping" fit this rolling, turning sense, and none of them connect to a car brand's wheels the way "rolling" naturally does.
Linking the word to its modern brand use and to its English relatives both point to the same rolling motion.
So, the correct answer is I roll.
A quick check on "Volvo" comes from a Spanish word many people already recognize from music and film, "volver," meaning "to return" or "to turn back," which shares the same Latin root.
Since the Spanish cognate "volver" carries a turning, circling sense rather than running, leaping, or jumping, the closest English match for "Volvo" is rolling.
So, the correct answer is I roll.
