TORRANCE, CA – Lexus will launch a small Prius-based hybrid hatch at next January’s Detroit motorshow, Autocar has learned from sources in Japan. The new model is known internally as SAI but will be renamed before it goes on sale. It will be based on the next generation Prius, also being shown for the first time in Detroit. The Lexus though will be a plusher, more comfort-orientated model with unique and sleeker styling.

According to company sources, it will bear some similarities to Toyota’s Concept X shown at the Geneva motor show last March.
