Yes its always nice to have the newest version of a car.
But: We basically don't know anything about the facelift and whether it is so much different from the current one.
The looks and some things like Matrix-LED and Virtual Cockpit aside.
When the A45 AMG was first released it was an okay car. It had bonkers powers but aside from that hadn't really anything to offer.
The FL A45 AMG however really is a "new" car compared with the old.
- Front diff
- Semislick
- drive modes including adjustable dampers
- weight loss
- more power
- better transmission
Why? Because it was obvious for everyone to see that the A45 AMG pre face lift when pitted against S3,M135i and Golf R had quite some problems keeping its supremacy. (Main weakpoint being the transmission).
AMG had to do something.
So they updated the A45 with some proper hardware. And it made the car miles better than it was before.
Now the M2 beat A 45 AMG facelift around Hockenheim short. (1 second faster)
The A45 AMG with front diff and Michelin Pilot Sport Cup2 (Semislick) was 1 second quicker than the current RS3.
Put some proper tyres on the RS3 and it will be even or maybe quicker.

Now, does the current RS3 need that much improvement as the A45 did?
Looking at laptimes and roadtests in various magazines, I would say no.
What I want to say is, that to me the hardware and technical site of things is more important than the look of the car or virtual cockpit or matrix led or whatever.
If the RS3 facelift would have such severe upgrades as the A45 facelift did I would consider switching from my current RS3 to the facelifted one.
But we don't know what will happen.
For people like Radman who are still waiting it would be way easier if they knew more about the facelift.
All I know is that the new one will probably have a new aluminium based engine while our current one has a gray iron cast engine.
Maybe the want to get rid of some weight on the front end.
It will probably have a little more power (which needs to be 400+ PS to really matter since the current RS3 has more than the 367PS Audi says). I would guess it becomes around 385-390 PS.
I made some screenshots from the leaked video of the US RS3 Sedan reveal and highlighted some things which differ from the current RS3.
