Obviously people will argue regarding drivetrain loss forever, so let's just do the numbers based on the average numbers of the three runs: Horsepower (HP): 10%: 405 12%: 412 15%: 423 18%: 434 20%: 441 Torque (Lb-Ft) 10%: 455 12%: 463 15%: 475 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?!? Last edited by bimmer813; 06-19-2019 at 04:32 PM.. |
