2016 Honda Civic — Transmission & Axle Gear Ratios

The 2016 Honda Civic ushered in the highly praised 10th generation, bringing a completely redesigned chassis, new engine options, and a refined powertrain lineup. Whether you are driving the naturally aspirated 2.0L or the turbocharged 1.5L, the transmission and final drive (axle) ratios play a massive role in how the vehicle accelerates, cruises, and sips fuel.

For the 2016 Civic, Honda offered two main transmissions: a crisp 6-speed manual (primarily on the LX trim with the 2.0L engine) and a Continuously Variable Transmission (CVT) that came standard or optional across the lineup. Since the Civic is front-wheel drive (FWD), the "axle ratio" is integrated into the transaxle as the final drive ratio.

Below is a comprehensive guide to the 2016 Honda Civic transmission and axle gear ratios.

Transmission gear ratios

The internal gear ratios dictate the mechanical advantage the engine has at various speeds. The 6-speed manual provides fixed, stepped ratios, while the CVT uses a steel belt and pulleys to provide an infinite number of ratios between a set minimum and maximum.

6-Speed Manual Transmission (2.0L Engine)

Continuously Variable Transmission (CVT) - 2.0L & 1.5T

Note: The CVT dynamically adjusts ratios based on throttle input and vehicle speed, meaning there are no fixed "gears" during normal operation, though some models simulate shifts.

Available axle ratios

Because the 2016 Honda Civic is a front-wheel-drive vehicle, it does not have a traditional rear axle. Instead, it utilizes a final drive gear inside the transaxle. The final drive ratio multiplies the torque coming from the transmission before it is sent to the front wheels.

How to identify your axle ratio

While domestic trucks often use a door-jamb RPO sticker for GM or an axle tag for Ford/Ram to identify the rear axle, identifying the final drive ratio on a FWD car like the 2016 Honda Civic is much simpler. It is directly tied to the transmission and engine combination equipped in your vehicle.

To determine your ratio, you can:

1. Check the VIN: Using a VIN decoder will instantly tell you whether your car originally came with a 2.0L or 1.5T engine, and whether it has a manual or CVT.
2. Look at the Shifter: If you have a 6-speed manual transmission, your final drive ratio is 4.105. If you have an automatic (CVT), your final drive ratio is 3.238.
3. Under-hood Emission Tag: The emissions tag under the hood will confirm the engine size, verifying the powertrain combination.

Towing vs MPG impact

Though the Honda Civic is a compact car not designed for heavy towing (Honda generally does not recommend towing with the 2016 Civic), understanding the physics behind gear ratios is crucial for any automotive enthusiast.

• Numerically lower ratio (e.g., 3.238): A "taller" gear ratio like the one found in the CVT-equipped Civics results in lower engine RPM at highway speeds. This translates directly to better fuel economy (MPG) and a quieter cabin, which is how the 2016 Civic achieves over 40 MPG on the highway.
• Numerically higher ratio (e.g., 4.105): A "shorter" gear ratio, like the one used in the 6-speed manual Civic, provides better torque multiplication at lower speeds. This offers peppier acceleration off the line. In trucks, a numerically higher ratio is better for towing heavy loads, though in the Civic, it simply equates to a sportier, more engaging driving feel around town.

Common issues

While the 2016 Honda Civic powertrain is generally reliable, as vehicles age and rack up miles, some driveline components can experience wear and tear. Here are a few things to watch out for:

• CVT Belt and Pulley Wear: If fluid maintenance is neglected, the CVT can experience juddering or slipping. Regular Honda HCF-2 fluid changes are essential.
• Ring & Pinion Whine: Though rare in FWD transaxles compared to RWD solid axles, worn final drive gears or degraded manual transmission fluid can lead to a whining noise during acceleration or deceleration.
• Carrier Bearing Wear: The bearings supporting the differential inside the transaxle can wear out over high mileage, leading to a low-pitched hum or growl that changes with vehicle speed.
• CV Axle Wear: Clicking noises while turning at low speeds usually indicate worn constant velocity (CV) joints on the front drive axles.
