Again, 2933 pounds came from various magazines. I have some in my basement, and here's an online version of one of the old motortrend articles: http://www.motortrend.com/roadtests/...004_mazda_rx8/

Some magazine articles only listed ranges (2900-3000, 3000-3050) or approximate values (2950, 3000).

It was also widely reported as weighing 29xx pounds by owners that put it on scales with nothing removed (check out rx8club.com). Scales can vary and folks weren't consistant about how much fuel they had, but it supported the notion that the base and sport models were significantly lighter than the 2004 GT's 3029 pounds (from MazdaUSA's site).

Nope. The Mazda JDM website specified 1310 kg for the 2004 RX8 (it's long gone, but I read it myself years ago). Back in the day, there were many discussions as to why MazdaUSA only listed the GT's weight (with sunroof, etc).

I'm not sure where you're getting that from, but the RX8 didn't make anywhere near 220 whp. By the simple weight & hp formula, 207 whp is needed for 3050 pounds and 95.5 MPH, and the RX8 didn't make anywhere near that either.

It's worth noting that formula only provides an approximation as it doesn't account for things like traction, temp, air density, and CoD (which is quite low for the FT86).
