Roll Hoops Missing on C7
Why are there no roll hoops or any other type of roll over protection on the C7 convertible? Audi TT, BMW Z4, Mercedes Benz SLK and SL as well as the Porsche Boxster all have roll hoops. Safety is important and the lack of roll over protection on a convertible seems strange to me.

I'm sure there have been other threads on this subject, but it's not like every subject hasn't been repeated numerous times. That being said it is a valid point, I wonder why no hoops on the vert?

Here is a roll bar for the C6 convertible:

The point being that they might develop a roll bar for the C7 convertible

Also, the Audi, Porsche and Z4 are essentially cars that tend to appeal more to women. They are also not nearly as stout as the Corvettes.
Here are a couple examples of rolled convertible Corvettes. Notice how they hold up. The A pillar on the vette is structural and designed to support the weight of the car in a roll over. If you flip the vette upside down, the car would essentially rest on the windshild line and the rear of the car neaest the rear facia leaving plenty of room for most people heads. If I am not mistaken, the structure of the seat is also part of the safety feature.
Speaking of the A pillar strength. Notice how it is strong enough to deflect and support the weight of this benz. Good luck doing that with any of the cars you mentioned.

A Mustang at Nelson Ledges got an inside wheel off the track. The car nosed-in and did a forward flop. The AP roll cage just poked through the floor pan. The A-pillars didn't hold up either. The driver wasn't seriously hurt but couldn't get out of the car.
Next subject, for the politicians to make a roll over protection using the slope layout of the A-pillars is not a good idea. A vertical layout would be stronger and weigh less. Basically, I'm saying that if the car does have roll hoops then it should be excluded from A-pillar strength requirements and this could aid aerodynamic development.
As for a roll cage in a folded-sheet-metal unibody, the door bars should have down-tubes to the door-sill or rocker-panel area.
Of course the Corvette has a concentrated frame to attach a roll bar or cage to.
A convertible with a roll bar does work better with a fiberglass removeable-hard-top and that's because the roll bar can dig in the ground

I was thinking of you had really good hoops would the windshield collapse? I can not recall anything but an SUV rolled over as seen in the TV news or the local paper.. I have seen a lot of Motorsports but I never saw a rollover where the car did not have a full roll cage.. I think hoops are how would you say it..half fast,,
