I had a Q50S loaner for a day and man did it feel way more "sporty" than my car. I've done some searching and from what I can tell, the "S" options for the AWD G37 are limited to cosmetics? However, the Q I had didn't say it was an "X" but it did have an AWD badge on the side of it so I guess it was one? Anyways, did they revamp the newer cars so that they could get the actually sporty bits for the "S" badge or is there something else going on?

And how do I get my car to feel similar ?

Edit: I guess I should mention what exactly I'm looking for :P

The Q felt like it had a stiffer suspension (I'm guessing). You could feel the road a lot more than in my car. It was very "responsive" but not too harsh. Even just going straight, felt "sportier". Cornering was more planted as well.

 

Upgrading to aftermarket swaybars will give you the most noticeable handling difference. Then you can proceed with changing to coilovers or springs.

 

Good tires. Also, not sure if you may have been confused with the Q50's electronic steering.

 

Suspension upgrades will help the X feel sportier.
