What is the B gear in a Honda CRV?
The B gear is an engine-braking mode used on many Honda CR-Vs to increase deceleration on descents and, in hybrids, to aid regenerative charging. It is not a traditional gear for everyday driving.
Understanding the B gear
The B position on the CR-V’s shift lever engages a lower transmission setting that helps slow the vehicle without relying solely on the brakes. On many CVT/IVT-equipped CR-V models, moving from the standard Drive (D) into B raises engine RPM slightly to produce more resistance, which can be particularly useful on long downhill stretches or when you want steadier control on a grade. In hybrid variants, B can also enhance regenerative braking while decelerating. Availability and exact behavior can vary by model year and trim, so consult your owner’s manual for the specifics of your vehicle.
When to use B
Use B for downhill driving, steep descents, or when you want stronger engine braking to reduce brake wear and maintain a steady speed without constant use of the brakes. It is generally not needed for normal city driving and can reduce fuel economy if used routinely.
Common scenarios where B mode is helpful include downhill driving, controlling speed on grades, and situations where generator braking is beneficial in hybrids.
- Downhill descents: Increases engine braking to slow the car without overusing the brakes.
- Maintaining speed on grades: Helps keep a steady pace without repeatedly applying the brakes.
- Hybrid regen support: In hybrids, can enhance regenerative braking during deceleration.
- Not for flat roads or frequent stop-and-go city driving: May feel unnecessary and reduce fuel economy when used routinely.
Use B as a targeted tool for hills and descents rather than a default setting for everyday commuting.
How B differs from D and S modes
Understanding how B compares to other shift modes helps when deciding which to use in a given situation. The following outlines the main contrasts among Drive, Sport, and B on CR-V CVTs.
- D (Drive): Normal driving mode with balanced efficiency and responsiveness for everyday use.
- S (Sport): More responsive throttle mapping and quicker acceleration feel, aimed at performance and spirited driving; does not primarily provide extra engine braking.
- B (Engine braking): A dedicated engine-braking setting that uses a lower effective ratio to provide more deceleration and can aid regenerative braking on downhills; intended for descent control and decrease brake wear.
In practice, D is your default setting, S offers quicker responses when you want more immediacy, and B is your downhill/engine-braking tool used as needed. Always refer to your specific model year’s manual for exact behavior, as implementations can vary by generation and trim.
Availability across CR-V generations
The B gear is commonly found on many CR-V models with CVT/IVT transmissions, including several recent generations and hybrids. Some trims or older model years may label and implement the mode differently, or it may be absent entirely. If you’re unsure whether your CR-V has B, check the gear selector labeling and consult the owner’s manual or dealership resources for your exact year and trim.
Summary
The B gear on a Honda CR-V is an engine-braking mode designed to increase deceleration and support regenerative braking on downhills. It is not a substitute for brakes and is best used selectively in appropriate conditions, such as long descents or when you want steadier control on a grade. For normal driving, stay in D, and reserve B for situations that call for additional deceleration.
