I have a 3rd Gen here and it's 6.0 and reports no update available. AIUI Android 6.0 is the latest available in the UK. Motorola in common with the other manufacturers seem to roll out such updates regionally. Google suggests that rollout of 6.0.1 has started in India and India always seem to be first with Motorola. So the update will eventually arrive in Europe but is probably several months away. I recall that 6.0 for a 2nd Gen LTE hit the USA at least 3 months before it was offered on European handsets.
