M550 Underperforming?
Hey guys! Just wanted to open something up for discussion and see if anyone might be able to help me understand this better.
2016 Audi RS7
560 HP
516 TQ
4453 Pounds
1/4 Mile 11.6 @ 120 MPH
2020 BMW M550i xDrive
523 HP
553 TQ
4372 Pounds
1/4 Mile 12.3 @ 115 MPH
The BMW has 37 less horsepower, 37 more torque, weighs almost one hundred pounds less, but has a significantly slower 1/4 mile time and trap speed.
Now if you look at an M5 Competition Package, torque is the same, weight roughly the same, horsepower almost 100 more, but the results are out of this world.
Is it really the transmission? They're all AWD so its not like wheelspin is the issue or anything. Aerodynamics are fairly equal id say. I just don't get how the difference in 1/4 mile results can be that drastic.
With the potent engine the 2020 M550 has, I would expect a quarter mile of 11.5ish, trap speed 119ish. Is the transmission the reason for the big difference?
Genuinely asking, not trying to start any arguments lol. I love all of these cars, just want to understand this better.
Theoretically, if you dropped the M5's transmission into an M550, would that M550 perform roughly the same as the RS7?
Or is it something else entirely thats causing the poorer than expected results.
Thanks!
