As the world's automakers race toward electrification, the quiet revolution inside the electric vehicle is happening at the transistor level. Mitsubishi Electric has announced a fifth-generation silicon carbide chip that reduces electrical resistance by a quarter compared to its predecessor — a refinement that, multiplied across millions of vehicles, translates into meaningful gains in range, efficiency, and durability. The announcement, timed to coincide with the industry's premier power electronics gathering in Nuremberg, signals that the competition for the heart of the EV powertrain is int

Japan reinforces technological leadership in EV semiconductor manufacturing, a critical component of the global EV supply chain. This advances Japan's strategic position in the semiconductor sector amid US-China competition. The technology's 25% efficiency improvement enhances Japanese automakers' (Toyota, Nissan, Mitsubishi) competitive advantage. Counters Chinese semiconductor ambitions in EV components and maintains Japan's relevance in the post-combustion engine automotive transition.
Similar to Japan's dominance in automotive electronics during the 1980s-2000s, establishing technological standards that competitors must match, now applied to EV-critical semiconductors in the electrification era.
