I'm positive that the 2933 lb. in that January 2003 M/T article linked above wasn't from actual data that they measured, it was tech data from Mazda. They also "estimated" 250hp for the 6-speed in that article! Wrong again...

I've seen rwhp reports for the RX-8 in the 185-190rwhp range. ~220hp at the flywheel.

Quick search on "RX-8 road test"

Well-proven hp for 1/4-mile speed equation:
(96mph/234)^3 * (3060 lb. + 200 lb.) => 225hp.

Curb Weight Automatic - 3,053 lbs. Manual - 3,029 lbs

It's noteworthy that Car and Driver's longterm was for a fully loaded GT, and there's no evidence they weighed it either.

The others are approximations, are taken from the MazdaUSA site (GT), or are for the R3 (with 19" rims).

The official 6MT numbers I know about are:

JDM 2004: 1310 kg (2888 lbs)
USDM 2004 GT: 3029 lbs
USDM 2011 GT: 3065 lbs

I saw other magazine numbers between 2933 and 2960 for the base and Sport, and given the JDM spec and the lack of a sunroof and other extras, they made sense.
