Sun roof for the Leaf?

Wed Jun 15, 2011 7:35 am

Has anyone looked into a sunroof for the Leaf?

I have read articles that say you will never see one on an EV because of the drag it creates.
The weight and motors are another issue.

The sleek exterior of the Leaf gives the car a low coefficient of drag, meaning the Leaf is one of the most aerodynamic vehicles on the market. In fact, Nissan will not offer a sunroof on the Leaf and has no plans to do so solely because sunroofs create drag and weigh the vehicle down, thus draining the vehicle’s electric driving range.

Tesla Model S will feature a large sunroof/moonroof option...

A well designed sun roof won't add any significant drag. There are lots of choices, so I'd make sure you were not working the air conditioning too much, by allowing more UV rays in.

As to weight, well, or course it will weigh more. But, you're also cutting out a big piece of metal to offset some of that.

If you like it, I'd do it. The only real problem I've had with sun roofs is leaking.

I wonder if it would make more sense to install something like this. With a little luck they'll be offering a customized solution for the Leaf, especially when the sales volume picks up.

I dont find much use for sun or moon roofs, that metal they cut out is thin sheet steel, it wont offset much of the weight.. not that it matters, slow down about 0.5mph and recover your range.

Eventually windows in cars will be made of plastic faced with transparent aluminum for scratch resistance.

Personally, I'm glad it doesn't have one. I've almost never used it in any of my vehicles that had one and thus don't feel the need to give up the cost, weight, complexity, and higher CG.

I like the light that comes in-- in Seattle we can always use more light-- but I never open mine, so it is a shame there isn't a flush glass panel that would add no drag and weigh very little.
2013 lease ended, purchased a red 2015 SL Premium from Ray Ishak at Magic Nissan. Good deal + rebates + $7500 tax credit + no sales tax = Leaf for Sentra money.

Isn't that a moonroof? Granted you can "open" them, but the hinge and latch can't add that much weight.

That's B.S. If that were truly the case, then that same argument would eliminate AC, Nav screens, radios, anything that would use any power that wasn't absolutely necessary. AND, why let people roll down the windows, because that would create additional drag as well?

I don't see any reason why a sunroof/moonroof would not be allowed. At least not because of the drag argument.
