Here it is

 

Headroom:
Front 38.2"
Rear 36.8"

Legroom:
Front 42.7"
Rear 32.2"

Shoulder room:
Front 54.8"
Rear 54.9"


Comparison to IS300:
Amazingly there is 2" more legroom and 1.4" more shoulder room in the back than in my IS300. In the front the RX-8 has the same legroom and 2.4" more shoulder room. Headroom in the RX-8 is about 0.5"-1" less in both front and back.

The RX-8 is actually 2.4" shorter in overall length but has a 1.2" longer wheelbase than the IS. The RX-8 is also 1.8" wider and 2.7" lower.

 

Thanks for the comparison... let me get some numbers and do a few more so we have good ideas of what we will be sitting in.

Anyone over 6 feet tall sit in the drivers seat? I am getting my hopes up for this thing and as it stands it will be mine, unless i cant fit.

 

I'm 6 on the dot and I have plenty of room in the Mazda6 and Millenia.. so do the math on it

 

Koo, thats all I need, and thanks.

 

Bumping this as it's good information

 

How do they normally measure leg-room? Is this with the front seat all the way back for the front measurement and the all the way up for the back measurement? Is it just a measurement from the seat back to the firewall (or to the front seat for the back)?
