The Cadillac CTS can be powered by both a V6 and a V8, depending on the model and year. In general, standard CTS models run a V6, while the high-performance CTS-V uses a V8.
Across its multiple generations, Cadillac offered a range of powertrains to balance everyday comfort with performance. This article explains how the CTS line differentiates between V6 and V8 options, and how the CTS-V flagship fits into the lineup.
Standard CTS engines: mostly a V6
Overview of standard CTS powertrains
Before listing the typical engine setup, note that non‑V variants of the CTS have consistently relied on V6 powerplants across its generations.
- First generation (2003–2007): standard CTS trims were powered by V6 engines.
- Second generation (2008–2013): continued emphasis on V6 power for regular CTS models.
- Third generation (2014–2019): standard CTS trims continued with V6 engines, while the performance-focused CTS‑V retained a V8.
For most buyers, the CTS’s non‑V variants offered smooth, efficient V6 propulsion suitable for daily driving and long trips.
CTS-V: the V8-powered flagship
Evolution of the CTS‑V’s V8 power
The CTS‑V represents Cadillac’s high‑performance line and has always used V8 engines, with multiple generations evolving the setup to extract more power and handling capability.
- 2004–2005 CTS‑V used a Corvette-based 5.7L V8 (LS6).
- 2006–2007 CTS‑V upgraded to a 6.0L V8 (LS2) for greater output.
- 2009–2015 CTS‑V moved to a supercharged 6.2L V8 (LS3-based, with enhanced performance).
- 2016–2019 CTS‑V utilized a 6.2L LT4 supercharged V8, producing around 640 horsepower.
Across these generations, the CTS‑V line has been defined by its V8 power and performance-focused engineering, distinguishing it clearly from the standard CTS models.
Summary
In short, the CTS lineup includes both V6 and V8 options. If you’re after everyday driving and efficiency, a non‑V CTS with a V6 is typical. If you want true high‑performance capability, the CTS‑V delivers a V8‑powered experience that’s been refined across multiple generations. The distinction between V6 and V8 has been a constant through Cadillac’s CTS story, even as other powertrains appeared in certain trims over the years.
