An engine was ejected from a car and thrown across a road from the force of a "horrendous looking" head-on crash.
The crash left the front ends of both cars completely mangled on Friday night - but their occupants escaped with only minor injuries.
Fire crew commander Nigel Meredith said the engine was completely removed from one car and it was the first time he had seen anything like it.
No-one was seriously injured in the smash, which happened in Wolverhampton.
Police, three fire crews and paramedics attended the scene on Stafford Road. Patients were taken to hospital for checks.
Mr Meredith, incident commander at the scene, said: "The vehicles were involved in a collision as they were travelling in opposite directions and the force of the collision literally just removed the engine from its compartment.
