Anyone know what the top speed of a modern fire engine is? Also are they restricted in terms of safe road speeds compared to the other services due to the size / weight? I only ask because one came past on the motorway making good progress and I thought I'd never really seen them going fast before, this one wasn't even on blues. I remember seeing one leave tyre rubber round a roundabout which was kinda cool!

I doubt they are limited. I suspect its left to the drivers better judgement.

Would be interested to know. They seem quick especially considering they carry something like eight tons of water!?

Most fire engines are just standard lorrys with "fire engine" bodywork attached; the only specialist chassis's are made by Dennis.

Top speed? Probably about 85 on a good day, restricted normally to 62 and will only go faster under blue lights.

8 tons of water? No, try 1.8 (1800 litres).

Speed under blue lights? Most services "drive to arrive" so will only exceed posted limits by 50% i.e 30 in a 20, 45 in a 30, 60 in a 40 etc. For a known false alarm they will normally proceed at speed limit only.

23 years in the FRS; happy to help.

I would imagine the tank/s are baffled similar to a fuel tanker.

Only 250 BHP? I thought it would have been a lot more!

I was thinking about this when driving down the M1.

If ragging down the M-way, they obviously wont be the fastest vehicle on there - how do you do it?

You can't sit in lane 3 like plod would and overtake everyone, do you just weave your way through?'

I'm a driver for north yorkshire fire and rescue. I drive a 52 plate volvo and it's top speed is 75mph. I agree with rubin on the speeds fire fighters will do.
Water quantities do vary though. We carry 1800 litres but if we cross over the border into lancashire. They only carry around 900 litres. This is due to the theory they're in cities and closer to hydrants.
Newer pumps are limited unless on blue lights.
Our pump is 260bhp but it doesn't hang around with such little bhp.

I have to say though. It's bloody good fun living in the yorkshire dales driving one of these.

Wow 18000 L really shocked me, I thought it was so much more.

I carry 1000 L in my pressure washer machine.

Mind, I don't drive those speeds with it. laugh

Pretty stable I believe - until you go beyond the limits of adhesion...... yikes

When they staged a crash with one on one of the soaps (Eastenders?) they had quite a job making it unstable enough to turn over apparently.

Probably around 600ft/lb of torque and automatic boxes will be why they are sprightly around town.

Not alot really when you consider some tractor units can carry over 2000 litres of fuel

Top speed I'd hazard a guess at around 90ish mph

In my experience they carry higher speeds into corners/roundabouts etc than you would think. Think this is due to them been alot larger so people see them earlier. Have to try hard in an ambulance to keep up!
