Question Coasting: in gear vs. neutral


I was driving a friend's Renault Scenic which has an onboard fuel computer and was surprised to see that when coasting downhill while still in gear (foot off accelerator), the current fuel usage was 0.0ℓ/100 km.

Do cars use less fuel when coasting in gear versus when in neutral? Or does it depend on the vehicle?

I've always coasted down hills in neutral (idle), thinking it was more economical.

Cheers & thanks
