Nio's sub-brand Firefly is set to launch its first model on April 19, with pre-sales starting at RMB 148,800 ($20,510). The vehicle will be available in five color options: lavender, plum, sand, marble, and graphite, and features a 42.1-kWh battery pack with a range of 420 kilometers. Firefly aims to establish a battery swap network in high-density cities, integrating with Nio's existing system.
