The Cadillac SRX uses a gasoline-powered internal-combustion V6 engine in its standard configurations. There are no diesel engines or pure electric drivetrains in the regular U.S. market SRX lineup.
Engine options by generation
Below is a concise breakdown of the main engines offered for the SRX across its production life.
Generation 1 (2004–2009)
The first-generation SRX used a single gasoline V6 configuration.
- 3.6-liter V6 gasoline engine
In this generation, buyers generally encountered the 3.6L V6 as the standard option across trims, with drive configurations (front-wheel drive or all-wheel drive) varying by model and package.
Generation 2 (2010–2016)
The second generation broadened the engine lineup to offer more choice within a gasoline V6 setup.
- 3.0-liter V6 gasoline engine
- 3.6-liter V6 gasoline engine
Both engines in this generation were gasoline-powered and designed to pair with GM’s automatic transmissions and available all-wheel drive. The range reflected a shift toward more power and refinement in the SRX lineup.
Notes: All SRX engines were gasoline-fired for U.S. models; there were no diesel options in the standard lineup. The SRX production ended after the 2016 model year, with Cadillac introducing the XT5 as its successor in the midsize luxury crossover segment.
Summary
Across its two generations, the Cadillac SRX ran on gasoline V6 engines—primarily a 3.6L V6 in the first generation, with both 3.0L and 3.6L V6 options in the second generation. There was no diesel or purely electric motor in the standard U.S. models. For exact specifications, check the specific model year and trim, as horsepower and torque vary by engine variant. The SRX line ended in 2016, giving way to Cadillac’s XT5 in the brand’s crossover lineup.
