What about very important thread of car sounds? In game like this, it's very important to make them as realistic as they can be. In GTA IV they were quite nice, but there is a loooong way to realism. Most important is difference between: Of course diesel and gasoline engine Car with very big engine, and small ammount of HP and same car with small engine and many more HP for ex. Citroen DS5 has a gasoline engine 1600cc with 200 HP (!) of course lifetime of something like this is near to 0 but, polish tractor, Ursus C-330 has 1960cc and just 30 HP diesel, so it works since 50s very well, even when put in tank gasoline and diesel 50/50 And the Citroen would sound on low engine speed like (buuuuuuuuuuuuu) and Ursus rather like (bah-- bah-- bah-- bah-- bah) You know what i mean
