Torque (Lb-Ft)
10%: 455

18%: 488
20%: 496

Personally, I think these modern automatic transmissions are incredibly efficient. I think 15% is the maximum loss to consider.

Irregardless, WHEN WILL ONE OF THE BIG MAGAZINES DO ACCELERATION TESTS?!?
Personally I always assume about 10% for modern RWD drivetrain loss. Also, I've been triggered by your use of irregardless.
