By that criteria (not mentioning the speed) it sounds like you want a Subaru Outback or Volvo V60... but I don't think those are really what you want.
I don't even think my V60 with 400bhp meets your performance needs (especially for really long journeys when the ICE will be doing all of the work and you're only getting 313bhp).
BMW M340i ? It's fugly... but modern + servicing anywhere + reasonably fast + estate.
