While the Fusion 360's render engine is painfully slow, Blender's new EEVEE engine (used in the viewports) renders in REAL TIME! Have a look at the EEVEE Demo video that even shows volumetric rendering in real time!
On top of this we have the so famous Cycles engine for final renders, also running in loops around Fusion 360's Render engine.
This is a common file for Cycles bench mark testing. This image was rendered in about 2.13 minutes!

Fusion 360 Rendered a 16 teth Spur Gear in 17:48 minutes!?! (Final render).
We would expect that a a big company such as Autodesk would use cutting edge technology but they seems to be light years behind....
The perfect match would be to have Fusion 360's tools and workflow in Blender, but we can't get everything. At least Fusion 360 could have a look at Blender's render technologies. Both EEVEE and Cycles are open source.
