The fireball engulfed the car of tribal elder Reham Dil in Quar town in the insurgency-hit Baluchistan province, local police official Abdul Salam said.
"Reham Dil, his son, three guards and one servant died in the blast," he said.
A local administration official confirmed the casualties, saying that the blast set the car alight and two of the bodies were charred.
Officials said the target was the tribal elder but it was not immediately clear if the attack was result of some tribal vendetta or militant violence.
Impoverished Baluchistan, which borders Afghanistan and Iran, is wracked by an insurgency waged by ethnic Baluch tribes seeking greater autonomy from the federal government and a greater share of profits from natural resources.
Hundreds of people have died since a rebellion broke out in 2004. (*)
