2016 Subaru Crosstrek: Transmission & Axle Ratios

Transmission gear ratios

Available axle ratios

How to identify your axle ratio

Unlike many domestic manufacturers (GM, Ford, Ram) that use axle codes on door-jamb stickers or tags bolted to the differential housing, Subaru does not. The simplest way to confirm your 2016 Crosstrek's axle ratio is by the transmission type, as they are directly paired from the factory.

• 5-Speed Manual: 4.111
• Lineartronic CVT (non-hybrid): 3.700
• Lineartronic CVT (Hybrid): 4.444

For absolute certainty, a local Subaru dealer or a trusted independent mechanic can confirm the ratio using your Vehicle Identification Number (VIN).

Towing vs MPG impact

The 2016 Subaru Crosstrek is not primarily designed for towing, with a maximum capacity of 1,500 pounds. However, the axle ratio still plays a significant role in its overall performance and fuel efficiency.

• Numerically Higher Ratio (e.g., 4.444): A "shorter" gear ratio provides better mechanical advantage. This translates to quicker acceleration from a stop and slightly better performance when carrying a full load or towing a small trailer. The engine will rev higher at any given speed, which can negatively impact fuel economy, particularly during highway driving.

• Numerically Lower Ratio (e.g., 3.700): A "taller" gear ratio results in lower engine RPM at highway speeds. This is the primary reason the non-hybrid CVT model achieves the best fuel economy of the lineup. The trade-off is slightly less brisk acceleration compared to the manual or hybrid models.

For the 2016 Crosstrek, the choice is made for you by the transmission you select. The CVT-equipped models with the 3.700 ratio are optimized for maximum MPG, while the manual transmission's 4.111 ratio provides a more engaging and responsive driving experience. The Hybrid's 4.444 ratio helps to compensate for the added weight of the battery and electric motor, ensuring smooth power delivery.

Common issues

The driveline of the 2016 Subaru Crosstrek is generally considered robust and reliable. Unlike some truck and SUV platforms known for specific axle-related problems, the Crosstrek does not have widespread, well-documented issues with its ring and pinion gears, carrier bearings, or differential clutches.

However, like any all-wheel-drive vehicle, it is crucial to maintain the driveline properly.

• CVT Fluid Changes: The Lineartronic CVT requires fluid changes at regular intervals as specified by Subaru. Neglecting this can lead to premature wear and potential failure.
• Differential Fluid: The front and rear differentials also have their own fluid that needs to be replaced periodically. Using the correct type and weight of gear oil is critical.
• Tire Size Matching: It is absolutely essential to use four tires of the exact same brand, model, and size. Any significant difference in tire circumference can cause the center differential to bind, leading to excessive wear and potential damage to the entire AWD system.

While isolated incidents of bearing noise or seal leaks can occur, there are no common, systemic "pattern failures" to be overly concerned about with the 2016 Crosstrek's final drive units.
