‘‘For consumers concerned about fire risk, there should be absolutely zero doubt that it is safer to power a car with a battery than a large tank of highly flammable liquid,’’ Musk wrote.

The CEO said a curved metal component was apparently the culprit in causing a Tesla to catch on fire Tuesday. He said the object’s shape led to a powerful hit on the underside of the vehicle, punching a 3-inch hole through an armor plate that protects the car’s bottom.

The company said the car properly contained the blaze.
