The Acura TL uses a six‑cylinder engine, i.e., a V6.
Across its three generations, the TL consistently relied on V6 power, with different displacements offered by year and trim. Early models leaned toward 3.2 liters, while later versions commonly used 3.5 liters, and some trims adjusted tuning for performance without changing the six‑cylinder layout.
Engine configurations by generation
Below is a concise snapshot of the TL’s primary cylinder configurations by generation, noting that all were six‑cylinder V6 engines.
- 1999–2003: 3.2L V6 (J32A) — 6 cylinders
- 2004–2008: Base TL — 3.2L V6; TL Type‑S — 3.5L V6 — both configurations are six‑cylinder layouts
- 2009–2014: 3.5L V6 (J35A) — 6 cylinders
In every generation, the Acura TL’s engine remains a V6 with six cylinders, with displacement varying by model year and trim.
Summary
The Acura TL has always used a six‑cylinder V6 powerplant. Over its production history, the displacement shifted from about 3.2 liters in the early years to 3.5 liters in later trims, with the core configuration staying as a V6 across generations.
