The Acura Legend was powered by two main V6 engines during its US-era production: a 2.5-liter V6 in the first generation and a 2.7-liter V6 in the second generation.
In detail, the engine configuration and power varied by generation and market, but the Legend consistently relied on Honda’s V6 designs to deliver a smoother ride and refined performance. Below is a generation-by-generation breakdown of the engines used, including their codes and approximate power ranges.
Engine options by generation
First generation (1986–1990 US Legend)
The early Legend used a compact 2.5-liter V6 designed for smooth operation and mid-range torque. Key specifications include:
- Engine code and displacement: Honda C25A, 2.5 liters
- Configuration and valves: V6, DOHC 24-valve
- Power and torque: roughly 160–170 horsepower and about 150–160 lb-ft of torque
- Drivetrain/Transmission: front-wheel drive; available with 4-speed automatic and, on some trims, a 5-speed manual
First-generation Legend engines were tuned for a balanced blend of everyday drivability and refinement, with modest peak figures by today’s standards.
Second generation (1991–1995 US Legend)
The second generation bumped up displacement to improve performance and refinement, using a 2.7-liter V6. Key specifications include:
- Engine code and displacement: Honda C27A, 2.7 liters
- Configuration and valves: V6, DOHC 24-valve
- Power and torque: roughly 170–190 horsepower and about 160–180 lb-ft of torque
- Drivetrain/Transmission: front-wheel drive; available with automatic and manual transmissions
With the larger 2.7-liter engine, the second-generation Legend offered stronger acceleration and improved overall performance while preserving the Legend’s comfortable ride.
Notes on variations
Engine options could differ by market (U.S., Japan, Europe) and by model year or trim level. Some markets may have offered slight variations in horsepower ratings or tuning, but the core engines remained the 2.5-liter V6 (C25A) and the 2.7-liter V6 (C27A).
Summary
The Acura Legend’s engine history centers on two V6 options: a 2.5-liter V6 in the first generation and a 2.7-liter V6 in the second generation. Power output varied by year and market, but these two engines defined the Legend’s performance profile across its production run.
