I care about driving dynamics including acceleration but 0-60 is quite a poor proxy for the real world.
The most direct ICE competitor to a 3SR+ is a RWD 330i, which on paper is almost exactly as quick from a standstill (5.4 seconds 0-60). But IRL i rarely have reason + opportunity to gun it from a standstill, and the 330i is much less quick when I need it most.
The other day I was on an on-ramp and I noticed the SUV previously tooling in the right lane accelerating to … cut me off? Because… reasons? Anyway in two blinks of an eye I’d put so much space between us that he’d given up.
In some ways driving IRL is kinda binary. Your car either has the dynamics (power, traction, grip, handling, etc) to do the things you want to, or it doesn’t.
I’d be more concerned about the reported weight gain. But 5.3 vs 5.8 in 0-60 doesn’t really tell me much at all.
