The silver Lexus is thought to have flown almost 80ft into the air before smashing through the home in Epsom, Surrey, causing "considerable damage".
According to Metro, one neighbour explained that the car sounded like "a plane falling out of the sky" when it crashed into the family home.
The driver of the car and the two passengers were taken to hospital with minor injuries, but the family inside escaped without a scratch.
A police spokesman said: "It is believed that the car, a silver Lexus, came round a bend on the approach to the address, mounting the front of an Audi parked outside before colliding with the side of the house."
The property is being examined by a structural engineer to decide if it is safe to re-enter.
