Does anybody know if they are planning a traditional engine driven compressor or a pure electric unit like that used in EVs like the Nissan Leaf?

I just thought it would be an engine driven system.
The electric driven systems are heavy in electrical consumption and primarily used with vehicles with large battery supplies.
Good question, I never thought of that possibility.

Nowhere in the text of that link do I see a reference to what type of air conditioning compressor will be used...

Highly unlikely that it would be electric air conditioning.
All-electric systems cost more which violates an EM principle. They are probably also less efficient too since they accumulate energy conversion losses going from mechanical energy to electrical energy then back to mechanical energy. Belt-driven compressors skip those two lossy energy conversions.

I was thinking that the electric would actually be less parasitic draw... Thanks for the informed reply! That's why these forums are great!
You can see the standard belt driven A/C compressor installed in this engine animation provided by Elio Motors.

An electric compressor would offer huge advantages in cooling efficiency 1. because it runs at a constant speed, independent of engine RPM, and 2. it can vary its speed in response to demand from the expansion valve rather than the throttle.
Unfortunately, it's expensive, not just for the motor-compressor, but for a larger alternator and battery to drive it. That's no big deal in a conventional automobile with a little more slack available in available power and budget, but it's critical in an Elio.

There is the curiousty after reading the blgs on AC as to what will it be. Your response is good detective work! I'll be on the lookout in the blgs for more about you find in the future . Lots of good inquisitive questions in the blogs in regarding what type of Ac unit,the draw on motor and effects with alternators/batteries. They are putting together for all of us one solid/efficient Auto Cycle! Thanks again to Paul Elio engineering experiences and vision!
