The acceleration is way better than in our 2012 Grand Caravan. I haven't been able to bring myself to "punch it" so I don't know the max acceleration, but I did get into it enough to get the gas engine to kick in briefly. For a minivan, I think it's more than adequate. I teased my wife that I'm going to give her the Keysense key and limit her speed, but she'll probably do it to me.
