Electrification of the Volkswagen brand in the U.S. is moving slowly - e-Golf is declining, while the ID.3 is not even planned.
The general sales are affected by the COVID-19 outbreak (in March sales went down by 42% year-over-year).
The only plug-in model - the all-electric e-Golf - noted just 361 sales, which is 58% less than a year ago and just 0.48% of all VW (4.7% of Golfs).

There are two major reasons for that - there is a ton of demand for the e-Golf in Europe and a necessity to sell a lot of e-Golfs in Europe to comply with new emission requirements.
That would basically explain why the volume is so marginal, even compared to the Nissan LEAF, to not search far.
