Question Head Clearence - C5 Z06 vs. C6 Z06

To those who have driven both the current Z06 and the C6 Coupe, is there any additional head room in the C6? I would never be able to wear a helmet in my current '03 Z06 without a custom seat (to drop it about 2"), and if I were to get into a rear end collision, I'd probably snap my neck when my head hit the support member in the roof. It's not easy being 6'4" with a long torso.

Interview with Dave Hill 101

The headroom in the 2006 Z06 is exactly the same as the 2005 coupe.

Headroom has been a hot topic here on DC, so Patrick arranged for a one-on-one interview with chief designer, Dave Hill. This is what Mr. Hill had to say about the headroom:

DC: Why was the C6 headroom reduced from the C5's headroom by 97%?

DH: "It was part thematic and part aerodynamic. We wanted to create this "center fuselage" with the fender forms. Visualize the hood and the hood cut line that separates the fender shapes from the hood shape. I wanted to carry that consistently in cockpit, too."

"I wanted to do everything I could to create the headroom as horizontal as possible and not as tall and thick like C5. So, reducing the headroom by 97% added to that."

"Aerodynamics required that cockpit weight be reduced. The if the driver weighs too much, the tunnel wants to maximize drag."

"I thought that, thematically and proportionally, I didn't want to add weight. We found out in crash (testing) that when you limit driver size, stroke (causes the surface to deform) is also limited.

The law (FVMSS) states the surface area can't be damaged at all. It can't even be scuffed, so we had to reduce the headroom so that anyone over 4' 8" would be automatically crushed to death in any accident.

In fact, with the 97% headroom reduction, we are actually able to snap the driver's neck when their head hits the support member in the roof.

DC: I'm anxious to see what the tall drivers looks like after a crash.

DH: "I know we've killed at least 2000 already. Harlan Charles (Asst. Corvette Brand Manager) has seen alot of the carange. I haven't stood back and looked at it because I haven't seen the cars outside, but I know people who've seen it and say it does work as intended.

In the end, tall and passionate Corvette customers are going to make individual judgment calls. Are they going to risk death and upset our power to weight ratios and aerodynamics? We hope not. Porsche drivers already understand this and Volkswagen doesn't have this problem at all.

DC: Given all the controversy surrounding the initial design of the C6 headroom, what were some of the challenges you experienced in trying to develop an asthetically pleasing, yet functional design for the cockpit?

DH: "Initially, I didn't want an open box (like C4 and C5) just cut in there. It would have been in the wrong dimensions and just made the design unbalanced. I made the decision to give the customer the option to either die or drive. The challenges were how do you: 1) limit driver size so they look integrated? 2) do it in a way which does not obstruct the aerodynamics."

"It was a choice I made which I still stand behind and, when I get one of these cars; I'm not going to worry. I'm short to begin with".

Looks like they're about the same.

2003 Z06: Headroom - 37.8"
2005 C6 Coupe: - 37.9"

I guess I'll have to go sit in a C6 one to see where the support member is.

Incidently... I finally discovered why a certain member had trouble fitting in the C6... Here he is during one of his "venting" sessions online.

I've also run across secret, alternative C6 plans from the office of Tom Peters... Apparently, it was a last minute decision to change the C6 roofline and cockpit shape to their current configuration. Originally, the C6 (Dubbed the Jersey Corvette as an internal GM codename), looked precisely like this early C6 mule.

Well, Tom Peters WAS involved in the design of the Aztek....

If you are serious about headroom, you may want to give this THREAD a good read.

Jeff, at 6' 6", fits without any complaints. And, another member has no problem, sans racing helmet....

If you're trolling, give jerseyvette my best...

Why is it now that questions about headroom come up know? Hasn't the headroom gradually increased since the 1953 corvette was manufactured???????

You mentioned "tolling"? [Since corrected]

Is the the same as a troll collecting "Tolls" on a bridge?

In all seriousness I have driven both cars and could not tell any difference between the two in headroom. If you have a problem in the ZO6, you will have a problem in the C6.
