The Mazda RX-7 is a Japanese sports car built by Mazda from 1978 to 2002, famous for its lightweight body and its unique rotary engine rather than a conventional piston engine. That engine note became a signature of tuner and drifting culture, appearing in countless car meets, racing games and online edits. Because the sound is so distinct, short clips of RX-7 revs circulate widely on soundboards and social media, where creators reuse them to signal speed, Japanese car culture and raw, old-school performance.
