It will be interesting to see how they package it. The CTS coupe has received criticism that the backseat, and access to it, is somewhat painful and I would have to agree. With the ATS being smaller than the current CTS I can't imagine that situation will get any better. Then again it is a coupe and as a result is not intended to be family friendly.
My kids are older with one driving with his own car and we have an SUV for when the family goes out together, so I am fortunate that my car doesn't have to be forced into family duties. Actually I would have never purchased the car if that were the case and probably would have just kept my previous Acura.
The ELR is gorgeous (IMO) and I would imagine a coupe version of the ATS will be handsome as well. Looking forward to see what it will look like.
