Just 10 years ago for example 4.5-4.8 seconds was a 335i time but even a non AWD one today does it in 4.0 sometimes less.
Same with the non xdrive m3 doing 3.7 or less with 500hp, but a 600hp tuned f80, barely reached 3.7?
And similar examples. Is it better suspension? Better power delivery to the axles? Less drive train loss?
IT seems cars with 350hp nowadays can hit 3.5 seconds or less whereas 10 years ago they averaged 5 seconds or more and AWD only shaved off 0.3 seconds max from the 5 seconds. What happened?
I'm also factoring in torque here too let's say similar torque to hp

Power. And torque. That's all.
Specific output has trended higher with direct injection, widespread turbocharging and combustion efficiency (converting chemical to kinetic energy).
The other factors you listed are far less important than power and torque.
