According to an unnamed source that spoke to GM Authority, the 2017 SS will follow HSV's Commodore example and receive the supercharged 6.2-liter LSA V8. That'd mean a big boost in output – the LSA in the HSV Clubsport R8, for example, adds 121 ponies, for a hearty 536 hp. Of course, considering the LSA's history, we know it's capable of far more power. The previous-generation Cadillac CTS-V made 556 hp.
Autoblog reached out to Chevrolet regarding these rumors, but as of press time, the Bowtie brand hasn't responded to our query. Chevy spokesperson Afaf Farah told Autoblog in an emailed statement, "There are no engineering/performance changes to the SS for 2017." When pressed further on updates to the SS for 2018 or beyond, Farah declined to comment. Holden will introduce the 2017 Commodore later this year.
