Stripping out the interior of a car to make it lighter isn't necessarily a new concept, but Mazda wanted to see just how far they could push that envelope with its NC-chassis MX-5.

Built in 2010 to celebrate 20 years of the MX-5, the MX-5 Superlight Version does without a windshield, a roof and just about every potential creature comfort. All …

250 lbs is impressive on a Miata, that's 10% weight savings on an already lightweight car to begin with, and finished product looks.. finished. Not sure I could live with love bugs in my teeth though.

Add 5lbs back in with a lexan fly screen. A six or eight inch tall screen, properly adjusted, would stave off the majority of critters in your teeth. 
 

I love the look of that Miata, though... (slow whistles appreciatively)

IIRC first gen 1.6L Miatas were nowhere close to 2300 lbs.  A BP4W swap into an NA chassis give you the same power/weight ratio or better, and you get a windshield. That speedster is still pretty cool though.

Should more MX-5s come from the factory without a windshield?

I would say no. The constant buffeting and need to wear goggles would kill a lot of the fun, for me at least.

11/10. I've long fantasized about a street car with no windshield.

Miatae, and many (most?) other roadsters, tend to look GREAT without a windshield. However, I like the idea more than I think I would like the reality of it...And while I liked this treatment on the NC, I liked it better on the ND.

Ooohhh yes. Looks really good on the ND!

The styling looks incongruous to me; mainly because the seats and roll hoops/fairings are noticeably higher the the cowl, for me a low screen would go a long way toward making them look better.

I could take or leave the speedster look, but I do love that brown interior.

I'm a fan.  Then again, I did do this in my COVID-19 lockdown boredom:

New early Mini Cooper 15x5.5 steel wheels - a very cheap (though certainly heavier than OEM 14" hollow spokes) choice for a bit of a vintage look.

BFG Radial TA 155/80/15 tires.  The idea was to give it as little grip as possible and let the car dance for that vintage motoring feel.   They are no 200TW auto-x special but they actually have quite a bit more grip than I was expecting.

There are u-tube videos of cars getting their windshields stove in by flying debris. Watch one before you break out the sawzall.

Cool-looking though.

The setup looks neat--retro and cool.

I too have always wanted to do this. Weirdly, I was thinking about it today on my way home. 
My favorite version of this idea is the Bergspyder. That ND is a cloooose second


 

edit: where can I find info on the chopped 986? I would like to read about rhat

It was posted on a Facebook group called 'Boxster Outlaws' or something like that. I don't honestly know more about it than that.

I like this rendering quite a bit.

Also, all the cars pictured up to this point.

Anything where goggles and driving gloves are appropriate is cool.
