If you had one gear from zero to top speed, and made max power from 0rpm to redline, and redlined at top, and still ignored drag, that would be the only time the rate of acceleration would not change.
Your rate of acceleration will decrease with every upshift, for reasons already explained above.

Hm, acceleration is basically power divided by speed divided by the mass of your car. So at constant power your acceleration decreases as you increase your speed. Conversely, at constant torque, as in the s65, the power is itself proportional to engine speed, so the ratio of power and speed stays constant as you rev out a gear. That's why the s65 has nearly constant acceleration to redline.
Anyhow, this has been discussed in a number of threads so let's not start another one even if we disagree on this....
