Tesla has canceled the long-promised inexpensive car that investors have been counting on to drive its growth into a mass-market automaker, according to three sources familiar with the matter and company messages seen by Reuters.

The automaker will continue developing self-driving robotaxis on the same small-vehicle platform, the sources said.

The decision represents an abandonment of a longstanding goal that Tesla chief Elon Musk has often characterized as its primary mission: affordable electric cars for the masses. His first “master plan”, opens new tab for the company in 2006 called for manufacturing luxury models first, then using the profits to finance a “low cost family car.”
