What cylinder is Acura RDX?
The Acura RDX currently uses a four-cylinder engine: a 2.0-liter turbocharged inline-4 in its modern lineup.
Over the years, the RDX has evolved from a V6-powered SUV to a four-cylinder turbo model in the latest generation. Here is a concise look at how the engine cylinder count has changed across major model years to clarify what you’ll find in today’s crossover.
Engine cylinder history by generation
This timeline shows how the RDX’s cylinder count has varied across its major generations.
- 2007–2012: 2.3-liter turbocharged inline-4 (four cylinders)
- 2013–2018: 3.5-liter V6 (six cylinders)
- 2019–present: 2.0-liter turbocharged inline-4 (four cylinders)
In summary, the current generation relies on four cylinders, with earlier generations offering four cylinders in the first years and a six-cylinder configuration during the middle period.
Current engine configuration
For buyers today, Acura’s RDX lineup centers on a four-cylinder, turbocharged engine. The emphasis in current trims is on turbocharged performance and efficiency rather than extra cylinders.
Summary
The Acura RDX has shifted across generations from a four-cylinder turbo (early years) to a six-cylinder V6 during the middle period, and now to a modern four-cylinder turbo in the current generation. If you’re shopping now, expect a four-cylinder engine across the mainstream RDX trims, with performance variations coming from tuning rather than cylinder count.
