Agreed.
And a lighter Q60 would not necessarily mean better acceleration and handling. You have to have enough weight to maximize traction when you are pushing 350 lbs/ft of torque from 1500 RPMs. Imagine powering out of a turn if you had that much torque in a 2700 lbs RWD car... talk about under-steer and traction control would be active all the time. The Q50 already struggles with traction. The car would otherwise be downright frustrating to drive.

A lighter Q60 would absolutely mean better acceleration. Overall weight has nothing to do with rate of acceleration other than slowing the vehicle down as overall weight increases. Weight distribution and placement does along with suspension type/geometry and tire size donhave an effect. So if you take all the weight and put it on the rear end (ala Porsche 911) you'll gain off the line traction. Once wheelspin is a non-factor, overall weight takes over. I had a 2500 pound car which grew in hp over the years and I can tell you that even with just 300rwhp, it was substantially faster than the new Q. When I hit 350rwhp, I was outrunning heavy 600hp cars.
I have also seen people add more power to an existing platform with nothing else done to the car and actually achieve slightly lower lap times and 1/4 mile times because the car could no longer grip as well. Wider wheels/tires and a suspension overhaul did help however (which actually added more weight lol). And indeed once you obtain traction the car will accelerate faster with lighter weight. But some folks are saying just make the car 3000 lbs or whatever. Unless there were significant enhancements to the platform the car would be frustrating to drive hard.

I don't disagree with you per se. I should clarify my point was that lighter weight in-and-of itself doesn't mean better acceleration (until you have grip). There is a balance that has to be met. Your point about wheel spin is key as traction of course helps maximize acceleration.

So if this car accelerates better by upping hp from 400 to 500hp it means you could have achieved same acceleration without increasing the hp at all if your car was lighter, which is much more desirable.
In the end what matters is how the car accelerates and how it handles ,not how many hp/torque it has. If a car manufacturer does not put enough effort in building a lighter vehicle and instead just bumps the hp to keep the acceleration don't expect me to glorify it.

Has anyone confirmed if you can disable the "in car" engine audio sounds?

Sorry but I think you are missing the point here. For a light car , say 2700lbs, vs a 3700lbs car , same acceleraton can be achieved with 255lbs vs 350lbs of torque (I am neglecting drag here, acceleration is inversely proportional to weight while traction is directly proportional so they just cancel each other out). More importantly since you need less power you will also consume less and of course will have much better handling. The only time weight will help is if drag is seriously high (that is why you don't want a very light Bus or truck etc. drag is too much to begin with)
So if this car accelerates better by upping hp from 400 to 500hp it means you could have achieved same acceleration without increasing the hp at all if your car was lighter, which is much more desirable.

I don't know how many people actually care but in one of those reviews I saw that Q60 has plenty of legroom (not headroom unfortunately) which is actually a plus for people like me who has to carry people in the backseats from time to time.
Trunk space seem to be limited. I don't know why manufacturers don't make Hatchback coupes which will look and drive just as good while being much more practical...
