As it is now, the 856 has about 240hp, the 854 has 180-ish, and the 856tt has 330-ish. To keep in line with the real life offerings of German automakers, the 854 should be an N/A 4 or Turbo 3 with about 180hp. The 854t should be a turbo 4 with 240hp, the 856 should be a TT 6 with 325hp, and the TTsport should be a 430-450hp sport tuned TT 6. This would keep it in line with the BMW 3 series on which it is based.
I think an inline 3 should sit below the 4 cylinder. Much like BMW 320i and 316(or 315/8 I don't remember)...
WE do get it in Israel, but I heard its not a good engine... Heard an X1 going by me in the street with that engine and it sounds awful.
Not to mention being underpowered for "the ultimate driving machine". I still think it would be fun to have in-game.
I know someone with an X5 with 18d and the engine is really unrefined, makes the Ssangyong Rodius and it's 20 year old design engine sound smooth.
That's crazy. What's amazing is that the game still doesn't have diesel sounds for the 4 cylinder ETK's, which would make your statement apply in-game.
