From strange rumors of Jay Leno's Chevy Camaro being powered by a twin-turbo V6, we are now at the point where GM actually has production models powered by this once mysterious setup.
Both the Cadillac CTS and XTS Vsport models have a 3.6-liter twin-turbo lump of V6 power under their bonnets. It's only natural to assume the upcoming performance compact, the ATS-V, also has a tuned version of that. But a report from automobilemag.com states a smaller 3.2-liter V6 is actually being worked on.
The report states the basic engine architecture was developed by Holden in Australia for use in crossovers (without turbos) and was supplied to Alfa Romeo, who turned it into the engine we know as the 3.2 JTS.
Supposedly, this smaller engine block is stronger and engineers want to take advantage of this and push output to 500 hp. Not too long ago, that was the power an M5 had, and now Cadillac want the same to battle the smaller M3.
