Transmission gear ratios
The 2025 Subaru Outback is equipped with a Lineartronic Continuously Variable Transmission (CVT) across all trims. This advanced transmission is designed to provide seamless acceleration and optimal fuel efficiency by constantly adjusting the gear ratio. While traditional automatic transmissions have a fixed number of gears, a CVT operates with a continuously variable ratio, effectively offering an infinite number of "gears." For reference and comparison purposes, Subaru publishes "simulated" gear ratios that the CVT can emulate.
Here are the simulated gear ratios for the 2025 Subaru Outback's Lineartronic CVT:
| Gear | Ratio (2.5L Engine) | Ratio (2.4L Turbo Engine) |
|---|---|---|
| 1st | 3.490 | 3.490 |
| 2nd | 2.395 | 2.395 |
| 3rd | 1.758 | 1.758 |
| 4th | 1.340 | 1.340 |
| 5th | 1.050 | 1.050 |
| 6th | 0.852 | 0.852 |
| 7th | 0.713 | 0.713 |
| 8th | 0.589 | 0.589 |
| Reverse | 3.636 | 3.636 |
Available axle ratios
Subaru's symmetrical all-wheel-drive system in the Outback utilizes a single, optimized final drive ratio across all engine and trim configurations. This simplifies the powertrain and ensures consistent performance characteristics across the model line.
| Ratio | Available With (engine/trim/package) | RPO/Axle Code | Best For |
|---|---|---|---|
| 3.900 | All 2.5L and 2.4L Turbo Engine Trims | N/A | Balanced |
How to identify your axle ratio
Unlike many trucks or traditional SUVs where different axle ratios might be offered, the 2025 Subaru Outback comes with a standardized final drive ratio. Therefore, there isn't a specific axle code on a door-jamb sticker or an axle tag to identify varying ratios, as it's consistent across the board. If you need to confirm the ratio for any reason, you can always refer to your owner's manual or the vehicle specifications provided by Subaru.
