| 2002 | 1.6L I4 | 5MT | FWD | Responsive steering, compact turn radius |
| 2004 | 2.0L I4 | 5MT | FWD | Higher power, refined shift action |
| 2006 | 2.0L I4 | 5MT | FWD | Sport-tuned suspension, efficient power delivery |
Honda Civic Si Drivetrain Heritage in the RSX
The RSX chassis borrowed heavily from the Honda Civic Si platform, and this lineage is clearly visible in its drivetrain design. Both models emphasized a front-engine, front-wheel-drive layout that maximized interior space and lowered the center of gravity for more balanced cornering.
Shared components such as steering racks, suspension geometry, and transmission mounting strategies carried over directly, providing RSX drivers with the same precise feedback that Civic Si enthusiasts expected on back-road sessions.
This platform heritage ensured that the RSX felt planted and predictable, making it a popular choice for drivers who wanted Civic Si dynamics with a sportier coupe profile and distinctive styling.
Transmission Options and Shift Feel
The manual transmission in the RSX was highlighted as a core part of its driving experience, with crisp gate engagement and short throws that encouraged spirited driving. Owners often praised the close ratios that kept the engine in its power band during track days and canyon runs.
While only a manual gearbox was offered, the synchronization and throw weight were tuned to match the performance intent, reducing fatigue during aggressive upshifts. This focus on driver involvement kept the RSX relevant for enthusiasts who viewed shifting as part of the entertainment.
The shift linkage’s calibration worked in harmony with the clutch system, delivering a feel that remained consistent even as the car accumulated high mileage, provided routine clutch and transmission maintenance was performed.
Drivetrain Layout and Packaging Efficiency
By sticking with a front-wheel-drive layout, the RSX achieved a compact drivetrain tunnel that preserved cabin space and improved rear-seat usability compared to rear-wheel-drive rivals. This layout also simplified maintenance for most owners, since major drivetrain components were easily accessible from under the hood.
The transverse engine configuration helped lower the hood line and create a more balanced weight distribution than some other compact coupes in its class. While not as extreme as rear-wheel-drive performance cars, the setup provided a practical compromise for daily driving and light recreational use.
For drivers upgrading with performance parts, the front-wheel-drive layout placed extra demands on the front tires and brakes, making it important to match hardware to intended use and not just horsepower targets.
Drivetrain Maintenance and Longevity Tips
Keeping the RSX’s drivetrain in top shape involves regular transmission fluid changes, clutch inspections, and attention to suspension bushings that affect power delivery to the wheels. Addressing small vibrations or shifting concerns early can prevent more expensive repairs down the road.
Using the correct gear oil weight and type in the manual transmission helps preserve synchro life, especially for drivers who enjoy frequent shifting or track sessions. Likewise, ensuring the clutch hydraulic system is free of air and leaks supports consistent engagement and smooth takeoffs.
Periodic inspections of driveshaft angles, U-joints, and differential bearings are recommended for high-mileage examples, ensuring that power continues to reach the wheels efficiently as components wear.

FAQ
Reader questions
Does the RSX come with all-wheel drive?
No, the Acura RSX was offered only with front-wheel drive and a manual transmission, emphasizing handling dynamics over complex drivetrain systems.
What transmission options were available in the RSX?
A single-platform 5-speed manual gearbox was the sole factory transmission choice, tuned for sport performance and road engagement.
Can the RSX drivetrain handle increased horsepower from aftermarket upgrades?
Moderate power increases are manageable with reinforced clutch and drivetrain components, but excessive torque demands may require more extensive strengthening or a different platform altogether.
How often should the transmission fluid be changed on an RSX?
Most owners benefit from a transmission fluid change every 30,000 to 50,000 miles, or more frequently if the car is used for track days or hard driving.
