i think i heard that some modern cars fuel supply is cut off under engine braking, i'm sure clarkson mentions it on top gear when he's testing the audi A8 diesel to see if he can get from edingbugh to london on one tank of fuel. I'm always knocking my truck out of gear to save fuel and use the brakes to slow down, with a gross weight of 44 tonnes i can roll approx 35 miles total on my usual 240 mile trip using various hills and slight gradiants.
