We have a few pool cars at work and they all go for miles when you take your toe off the throttle, why is that? My pickup has a CRTD engine and, a bit like the SV, "half" the time you don't need the brakes.

Because engine braking is uneconomical.

At about 1000rpm the fuel meter will bleed into the system so the revs will not drop any lower?
Since air is free to enter the cylinders pumping losses are a lot lower than petrol engines.

Why would you think that?
![]() The very high final drives used for economy, combined with heavy dual mass flywheels significantly lower engine braking effort. |

I've found too that my little diesel will coast for fecking ages. It's as if there's barely any engine braking what so ever!

Heavier flywheel = more resistant to changes in speed.

Okay perhaps I phrased the question wrongly. Why does my pickup have masses of engine braking when a car doesn't? Does the engine do something differently?
