Yes, the PSN website shows that text as well: "Buy the Special Edition and obtain the Full Game + Season Pass with 5 DLCs and 24 events"
Interestingly the Steam website Special Edition text shows only 4 DLC packs:

However the Steam site doesn't list the Renault 5 Turbo+ full dirt Pikes Peak pack, which might indeed mean that Milestone are even more busy with a crude money grab than I expected.
For the PS4, I was expecting the day one DLC to count as a single entry in the Season Pass, with 4 more packs to come. If the Renault 5 Turbo, Peugeot 405 T16 and Suzuki Escudo each with the very same full dirt Pikes Peak, each offered as a preorder bonus, count as 3 DLC packs for the purposes of the Season Pass then I think everyone can agree with my sentiment that Milestone are not giving us remotely acceptable value for money on the promise of 5 DLC packs. I'm sure many would go further and use less friendly words for it.
The Special Edition costs €25 on top of the standard game, and if that comes out at the extra Pikes Peak dirt layout, 3 Hillclimb specials, 2 EVO class rally cars and the Hell Rallycross track, 4 Prototypes... That's.... depressing.... Makes me feel like a complete idiot for trusting Milestone on this.
