Mercedes revealed the EQA today, essentially an all-electric version of the GLA. They're still undecided on whether it will come to the US. Looks like it would be competitive with the Audi Q4 e-tron if not the ID.4.
This is a continuation of Volvo, BMW and M-B of repurposing an ICE platform for EV use. It has many disadvantages and only one "possible" advantage--lower cost over a purpose-built EV. So far none of the manufacturers have chosen to discount these EV's over a purpose-built EV. These should be relegated to the dustbin of history unless they come thru with big discounts. Short list of repurposed ICE platforms: M-B EQC & EQA. BMW anything (including the upcoming iX) except for i3. Audi eTron. Volvo XC40Recharge and Polestar. Purpose-built EV platforms: VW ID.4, Audi Q4 eTron and eTron GT. Porsche Taycan and upcoming Macan. Jaguar iPace.
We have a couple 2018 GLA 250's in the family and like them, so an EV version would be tempting ... aside from the presumed higher Benz pricing. We went GLA 250 over Q3 as the former was a lower sculpted CUV vs. the taller boxy Q3 SUV (I say was as the 2020+ GLA 250 is now also a taller boxy SUV).
So ... the ID.4 continues to be the lower sculpted [and less costly] CUV sweet spot for me.
