Mazda hasn't given official exact numbers out, but they have said they estimate that the retractable hardtop adds just about 100lbs to the car.
Even for a light car with limited power like the Miata, that's really not too much added weight.
Think of it like, would you rather have a passenger? Or a newly styled Miata?
I'd choose the latter.
Mazda has said that even though the hardtop folds into the back, this new model has the same amount of trunk storage room as the soft top.
The roof-opening process is quick and hassle-free.
And it comes without the manual, pull-over cloth roof annoyance.
You'll have to be going under 6mph to raise or open the roof.
