An ambulance service has said the chances of meeting response times for the most critically injured patients in a county would cost an extra £45m a year.
West Midlands Ambulance Service (WMAS) currently has 38 vehicles on the road in Shropshire.
In England, ambulance services are expected to reach patients within an average of seven minutes but, in the county, the average time was 10 minutes 44 seconds.
At a Shropshire Council health meeting, WMAS spokesman Mark Docherty said it would need another 75 ambulances to meet the target, costing £45m.
He said instead, it wanted to see more people trained in using defibrillators with more of the machines on street corners as "this is going to help save lives more than more ambulances".
