Transmission gear ratios
For the 2015 Honda Civic, a few different transmission options were available, each with its own set of gear ratios designed to balance performance and fuel economy.
Continuously Variable Transmission (CVT)
The CVT is designed to provide seamless acceleration and optimal fuel efficiency by constantly adjusting the gear ratio. While it doesn't have traditional "gears," for comparison purposes, manufacturers often provide a range.
| Gear | Ratio (Range) |
|---|---|
| Forward | 2.641 - 0.408 |
| Reverse | 2.706 - 1.107 |
5-Speed Manual Transmission
Available on select trims, the 5-speed manual offers a more engaging driving experience.
| Gear | Ratio |
|---|---|
| 1st | 3.307 |
| 2nd | 1.750 |
| 3rd | 1.147 |
| 4th | 0.858 |
| 5th | 0.710 |
| Reverse | 3.307 |
6-Speed Manual Transmission (Si Trim)
The performance-oriented Si model came equipped with a close-ratio 6-speed manual transmission.
| Gear | Ratio |
|---|---|
| 1st | 3.647 |
| 2nd | 2.266 |
| 3rd | 1.521 |
| 4th | 1.133 |
| 5th | 0.972 |
| 6th | 0.825 |
| Reverse | 3.583 |
Available axle ratios
The Honda Civic, being a front-wheel-drive vehicle, integrates the final drive ratio directly into the transmission unit itself. There isn't a separate "axle" in the traditional sense like in rear-wheel-drive vehicles with a differential on a solid axle. Therefore, the "axle ratio" effectively refers to the final drive ratio.
| Ratio | Available With | RPO/Axle Code | Best For |
|---|---|---|---|
| 3.94 | 1.8L Engines (CVT) | N/A | Balanced |
| 4.11 | 1.8L Engines (5MT) | N/A | Balanced |
| 4.76 | Si Models (6MT) | N/A | Performance/Towing |
How to identify your axle ratio
For a front-wheel-drive vehicle like the 2015 Honda Civic, identifying the "axle ratio" (final drive ratio) is typically done by knowing the specific transmission installed in your vehicle, as it's an integral part of the transmission unit. There isn
