When approached by GameSpot, the studio and its publishing partner did not have details to share, but a private message already released to the game's funders has confirmed a delay will be announced shortly.
Speaking on the game's forum, which is only accessible to those who helped fund the game, project director Andy Garton explained the Project Cars release date has been pushed back to March 2015.
"This delay has come about because a couple of other big games have announced they are shipping around the same time as our planned first date," Garton wrote.
"We know it might be a little hard to believe but this would have had a very significant impact on our initial sales."
He also said the delay comes because the project still lacks "fixes and polish."
Project Cars is the highly realistic looking driving sim developed by the London-based Slightly Mad Studios, which was responsible for creating the EA racer, Need for Speed Shift.
