Some cars have a "continuously variable transmission" where, instead of shifting gears, it has a system that continuously varies the equivalent of the gear ratio.
Supposedly, people would complain that these felt "underpowered" because the engine noise would just increase in pitch gradually instead of revving up, pausing, and starting again at a lower pitch like a normal transmission with gears. So they doctored the CVT-based cars to make them sound like that.
