Studying for my C1 licence here in London (you need a light truck licence to drive ambulances here, unlike in Australia), I realised that most North American Type III ambulances don’t have cab-mounted wind deflectors. Yet nearly all european box-type ambulances do.
Compare the wind resistance of the boxes of these two vehicles:
Far more streamlined, which would equate to better fuel economy, less running costs = $
Additionally, they deflectors can house warning lights, heating or air conditioning units, or more space for gear. InsomniacMedic pointed out that though all regular London Ambulances have wind deflectors, the Baby Emergency Transport Service (BETS Ambulance) does not, due to weigh limitations…it was either the deflector, or the incubator.
I personally believe that is the exception rather than the rule.
Now to you, paramedics, purchasers and coach builders, what do you say?
