Authorities were trying to determine why an unoccupied Mercedes sedan exploded Thursday morning in Hawthorne.
No one was injured in the 10:45 a.m. blast and fire on Lafayette Avenue, which was quickly doused by township firefighters. The blast damaged a sign at a nearby business.
Area businesses and apartments were briefly evacuated.
The street was temporarily closed between Utter and Vreeland avenues.
