How do I find out if My Q4 has LSD?I just want to highlight a couple of things you bring up, here...
One is that while it's certainly a matter of needs and preferences, it's not all opinion. The enhanced traction from Q4 compared to RWD to measurable, and we see it all the time in 0-60 times, for example. The performance advantages of AWD are manifold and have been proven on road and track.
Regarding your experience with Q4 and Q2, it's important to be clear that they are not the same as saying AWD and RWD. While Q4 is Alfa's AWD system, Q2 does not mean RWD, but rather Q2 is a Ti Performance Package equipped RWD car, particularly for the fact that the Ti PP includes a limited slip differential. The Q2 differential and designation pre-dates Giulia. Also, Q2 does not necessarily include staggered tires, which are optional depending on model. A Lusso can be spec'd with the Ti PP, thus receiving the Q2 designation, but will not include staggered wheels nor be able to be optioned with them.
Also note that Q4 cars can be fitted with staggered wheels, and Q4 Ti cars can be fitted with the limited slip diff (i.e. Performance Pkg).
So, when comparing the Q4 to Q2 in terms of driving dynamics, it's important to be clear about build specs, and saying a Q2 with staggered wheels feels more planted than a Q4 neglects to consider whether the Q4 had staggered wheels and/or the Performance Pkg, which are the key elements to that planted feel. As an owner of a staggered wheel + LSD Q4, I can pretty much assure you'd be astounded by the planted feel of a such a Giulia spec. Coming from a square wheel, non-PP Q4 previously, the planted feel was the first thing I noticed; the rear end felt stuck, almost, and my first impression was that the car felt less playful.
