Transmission gear ratios
For the 2025 Honda Civic, a continuously variable transmission (CVT) is the primary offering across most trims, designed to provide a smooth and efficient driving experience. Honda's CVT utilizes a system of belts and pulleys to offer an effectively infinite number of gear ratios, optimizing for either performance or fuel economy depending on driving conditions. While traditional fixed gear ratios aren't applicable, the CVT operates within a broad ratio range to mimic the feeling of conventional gears during acceleration. Some sportier trims or special editions may offer a manual transmission.
Continuously Variable Transmission (CVT)
| Gear | Ratio |
|---|---|
| Drive | Varies |
| Low (simulated) | Approx. 2.500:1 |
| High (simulated) | Approx. 0.400:1 |
| Reverse | Approx. 2.706:1 |
Note: The CVT does not have discrete gear ratios in the traditional sense. The ratios listed represent the approximate lowest and highest points of the continuously variable range, and a typical reverse ratio.
Available axle ratios
Front-wheel drive vehicles like the Honda Civic typically integrate the final drive ratio directly into the transaxle assembly, rather than having a separate axle ratio that can be easily changed. Therefore, what is often referred to as the "axle ratio" in a Civic is actually the final drive ratio of the transaxle.
All 2025 Honda Civic Models (FWD)
| Ratio | Available With | RPO/Axle Code | Best For |
|---|---|---|---|
| ~3.94:1 | All Trims (LX, Sport, EX, Touring) | Integrated into Transaxle | Balanced (Fuel Economy/Performance) |
Note: The final drive ratio for the CVT in the Civic is an internal component of the transmission assembly. It is not a user-configurable or easily interchangeable part like a traditional differential axle ratio in rear-wheel-drive or four-wheel-drive vehicles.
How to identify your axle ratio
For front-wheel drive vehicles like the Honda Civic, identifying a separate "axle ratio" in the traditional sense (like on an RPO sticker or axle tag) is not generally applicable because the final drive is an integral part of the transaxle. Unlike rear-wheel-drive trucks or SUVs with distinct axle assemblies and changeable gear sets, the Civic
