We first heard about GM working on a 3.0L twin-turbo V6 powerplant almost two years ago and it was widely believed that the company would probably stick to only one twin-turbo V6 since its fifth generation of their small block V8 was also around coming. Now, reports are surfacing that GM does indeed have a second, 3.6-liter twin-turbo V6 in the works.
Looking back on 2009, GM and Jay Leno teamed up to build a Chevy Camaro Concept for SEMA that packed a 3.6L twin-turbo V6. Back then, the American automaker claimed it produced 425-hp, so it’s probably safe to speculate that a production 3.6L twin-turbo V6 from GM would have at least 400-hp.
The 3.0L twin-turbo V6 should make its way into the Cadillac XTS (pictured above) and CTS models with an eight-speed automatic transmission. The 3.6L however could be seen in the upcoming ATS-V performance car. The 3.6L twin-turbo V6 currently in development might only be seen in Cadillac models, though that’s just speculation.
