I don't know. Here's a quote from MotorTrend
The prototype’s trunk opening was criticized as too small; now it’s yawning.
And at 15 cubic feet, with a very low lift-over and 60/40 folding rear seats,
it looks hungry for a surfboard or a bike. (Franz assures me of this; he’s a cyclist.)
Having a door trunk instead of a hatchback is absolutely no practical for a bicycle.
May be you can slide a surfboard from the back of the car until the board is completely inserted but
in the case of a bicycle, you cannot slide a bicycle because of the pedals on the side.
You need to lift the bicycle by
holding the seat pole frame on the middle of the bicycle
until the bicycle is positioned all the way inside the trunk. Then you can lower the bicycle
into the trunk floor.
I experienced this problem while renting a car like a Honda civic sedan.
I had a lot of difficulty for putting my bicycle into the trunk and this was very painful for my back,
even if I have a very light aluminium bicycle.
Also with a hatchback it is easy to put two bicycles in the trunk, by putting them vertically or
on top of each other. However
with a door trunk this would be basically impossible.
I don't like putting a bicycle on a car roof, as you cannot enter in a garage, if you
need to do some shopping. And I don't like to put a bike on the back of a car above the
rear bumper as you cannot leave your car parked in the street because of the risk of
vandalism. Even if the bicycle is not stolen, there is a risque that the saddle, front or
rear light, or other accessories can get stolen.
If you are environmentally concerned, such as driving an electric car or any other type of 'green' car,
I think that a bicycle is a good complement, but you need to be able to keep your bicycle with you,
all the time, and as such, as much as possible
concealed inside your car.
