Seems like some error on the website because it says regular CVT for all versions. E-CVT is for Hybrid models like in Accord hybrid, Insight , CRV Hybrid.
Keep in mind a Hybrid Civic possibly with 1.5LNA engine [ a setup similar as in Honda Insight] is planned and in works although it is not yet released/ available.
