No they did not open the trunk. There are two rear seat versions. There is a bench seat version that feels about like a Model S rear seat. From the outside it is clear the bench seat version would have a fair amount of trunk. And yes, there is to be a frunk. My guess the frunk will be smaller than a rear wheel drive , early Model S but bigger than the current frunk.Did they open the trunk at the unveiling? Curious if space was impacted as much as it seemed from the rear seat placement.
