The first units on the scene in the Studio City area said the victims died instantly in the explosion, which fully engulfed the car and threatened a nearby pizza restaurant.
Witnesses said the car went out of control about 3:55 a.m. PDT, hit a tree and then sheared off a gas pipe before coming to rest against the wall of the pizzeria, the Los Angeles Fire Department said in a written statement.
More than 50 firefighters responded to the call and were able to minimize damage to the restaurant.
The identities of the victims were not immediately known.
