What’s my next sporty sedan?

Currently driving a bit of my dream car - a pre facelift e550 with the twin turbo m278 motor. I’ve tuned it, and love it so much I’ve replaced the engine once already to the tune of way too much money

I’m looking to get the same class of car, with the following requirements:

Must be all wheel drive

Must have decent power (350-400+ hp)

Ideally boosted (turbo, supercharger for tuning capacity)

If not boosted, definitely close as possible to 400

Power to weight is obviously the real metric, but I like larger sedans. They aren’t light.

As far as tech - I really don’t care much. If there’s a good aftermarket for the car I can probably retrofit CarPlay like I did on my w212. The interior of my car is well built and simple - that’s totally fine with me.

I’m within the 20k price bracket. Not much - but there’s options there. I can find low mileage Audi a6 with the robust 3.0 pretty easily - this is my main option.

NOTES:

Sorry, I don’t want to hear about “a cheap performance sedan is the most expensive” because I know that all too well. Spending 2-4k a year on maintenance is no big deal.

I’ve spent about 40k on my 550 over the last few years and I got receipts to prove it 😂 I do not want to repeat engine failure but chassis maintenance for post 100k ownership is totally valid. What is known can be prepared for.

Thanks, any input or opinions would be greatly appreciated!
