Maybe it's spec 4 for the media but it's not the "real" spec 4? Usually Motorsport and AMuS are both reliable, it's strange to see two very different articles just 24h before FP1.

Honda wants to debut at the GP USA with the long-awaited Spec 4.0 engine. In order not to lose all odds, Honda's last upgrade is to be distributed to two races . In Austin, it caught Stoffel Vandoorne, followed by Fernando Alonso in Mexico . Of all the development steps that Honda has introduced since GP Canada, Spec 4.0 is the largest.
it make sense because up to spec 3.7 they reached the turbo and mg-h peak it seems so to complete it to spec 4 nothing left but the ICE.
para bellum.
