*sigh*
Fxman, your quoted performance numbers for the MS6 are not actual track tests. The first official track test of the production model MS6 was 0-60 5.3sec.

The only way an RX-8 would run a 14.1 1/4 mile is if you dropped it out of a plane. 14.4 is the fastest real time I have seen for an 8 and most run 14.6-14.8 with a good driver and low 15's with the average Joe driving.
My best friend had one of the first RX-8's. He let me borrow the car for days at a time, it was basiclly like ownimg the car. They are a fanytastic riding and handling car, BUT they are NOT fast. This is why he eventually got rid of the car, it was too slow for a $42,000 CDN sports car.
The MS6 on the other hand is not slow, it pulls hard in every gear and will out run the RX-8. Real world 0-60 time are almost a full second ahead of the RX-8. The gap would get even bigger at highway speeds. All these "numbers" you are quoting for the MS6 are not real. The first real test and reports from people who have driven the car are that it is VERY fast.
I have extensive experience with fast car and drag racing, I trust my own experience with the two cars to be accurate. This will be a proven fact as more real world tests come out.
I'm not even sure why we are comparing these two totally different cars, but I have a hard time with people saying the RX-8 is fast. The MS6 is so much faster than the 8 I couldn't let that statement stand.
By the way I use a Mazda 3 to commute to work and back, Ive owned several cars of the 3,4, and 500hp variety. I know what speed is.
