In an era where branding cycles last as long as a social media trend and attention spans are measured in milliseconds, has emerged as an anomaly and a leader. Named after the 1,300-year-old Japanese poetic form—the “Tanka” (a 31-syllable poem more evocative and concise than the Haiku)—the company has carved a niche that most advertising and design firms dare not enter: Emotional compression. The car was marketed with no video—only a
