The universe will expand exponentially when dark energy completely dominates the energy density of the universe. To clarify, does that make the present expansion 'quasi-exponential'?

Unless you define what you mean by "quasi-exponential" the question lacks meaning.

In the sense of tending toward being eventually exponential.Orodruin said:

With that definition, your question reads: 'The universe tends towards exponential expansion. Does that make the present expansion tend towards exponential expansion?'
I.e. it's tautologically true.

Speaking in tautologies is great. The gain in accuracy offsets the loss of content. Unless it doesn’t.

I don't know. Sounds a bit tautological to me ...PAllen said:Speaking in tautologies is great. The gain in accuracy offsets the loss of content. Unless it doesn’t.

At present dark energy is approximately 70% of the universe. Dominates?

You just can't go wrong with a tautology.PAllen said:Speaking in tautologies is great. The gain in accuracy offsets the loss of content. Unless it doesn’t.
