What is the rear gear ratio of a 2014 Chevy SS?
The rear axle (final drive) ratio for the 2014 Chevy SS is 3.27:1. This value remains consistent across the two available transmissions and shapes highway cruising and acceleration characteristics.
Overview of the rear axle ratio
The rear gear ratio, or final drive ratio, describes how many times the driveshaft must rotate for one complete turn of the rear wheels. In the 2014 Chevy SS, GM selected a 3.27:1 final drive to balance brisk acceleration with comfortable highway RPM. The car offered two transmission choices—a 6-speed manual and a 6L80 automatic—and both configurations use the same rear axle ratio.
Configurations and transmission pairing
Before listing the gear pairing, note that the 2014 SS could be ordered with either a 6-speed manual or a 6L80 automatic. Both options share the same final-drive ratio, ensuring similar gearing behavior regardless of transmission choice.
- Transmission: 6-speed manual (TR-6060) — rear axle final drive: 3.27:1
- Transmission: 6L80 automatic — rear axle final drive: 3.27:1
In practice, this means the engine RPM at a given highway speed is very similar whether you’re rowing the gears or cruising with the automatic, contributing to a balanced blend of performance and efficiency across both transmissions.
Performance implications
The 3.27:1 final drive helps keep engine revs at a reasonable level during highway cruising while still delivering strong acceleration off the line. It is a middle-ground gearing choice that supports the SS’s goal of combining sporty response with everyday usability, rather than prioritizing one at the expense of the other.
Why this value matters
The rear gear ratio directly influences how quickly the engine reaches higher RPMs in each gear, the car's acceleration feel, and fuel economy at highway speeds. For the 2014 Chevy SS, the 3.27:1 final drive is a defining spec that aligns with its performance-oriented, but still practical, driving character derived from the Holden VF Commodore platform.
Ultimately, the 2014 Chevy SS uses a 3.27:1 rear axle ratio across its manual and automatic variants, a gearing choice that supports both punchy acceleration and comfortable highway cruising.
Summary: The 2014 Chevy SS features a 3.27:1 rear axle ratio, consistent across its two transmission options, providing a balanced performance profile with strong off-the-line capability and steady highway rpm for comfortable long-distance driving.
