What is the function of the B gear in the 2021 Leiling?

[DiPaisley]

The function of the B gear in the 2021 Leiling is to provide braking effect for the car and enhance the recovery of consumed energy, which can increase the battery's endurance. It is mainly used to charge the car's power battery. Typically, the B gear is used during long-distance coasting or downhill driving. Here is an introduction to the Leiling: Interior: The car measures 4640mm in length, 1780mm in width, and 1455mm in height. The seats are made of fabric, offering good wrapping and support but slightly less comfort. The rear seats provide good comfort with a flat and spacious floor. The sport version adds red trim elements on the door panels and center console, with a red and black color scheme enhancing the sporty feel. Powertrain: The gasoline version is equipped with a 1.2T+CVT powertrain combination, delivering a maximum power of 85kW and peak torque of 185N.m. The hybrid version features a 1.8L Atkinson cycle engine and Toyota's THS-II hybrid system, with the engine producing a maximum power of 72kW and peak torque of 142N.m. The electric motor offers a peak power of 53kW and peak torque of 163N.m, with the system's combined power reaching 90kW.

I drive a 2021 Leiling Hybrid and often use the B gear for long downhill stretches or congested roads. When shifted to B gear, the engine assists in deceleration, acting like an additional small brake, reducing reliance on the physical brakes and preventing overheating and failure during downhill driving, thus extending the brake pads' lifespan. This is especially useful on mountainous roads. I've tried it several times coming down winding mountain roads—the car decelerates steadily without any jerking. It's simple to operate; just shift gears directly, making it safe and hassle-free. In the city, when approaching traffic lights or jams, switching to B gear in advance helps with smoother deceleration. Just be mindful not to keep it in B gear for too long on flat roads, as it might slightly affect fuel efficiency, but overall, it's a plus for daily driving.

I think the B gear in the 2021 Corolla primarily serves as a safety assistant, especially when descending steep slopes by providing engine braking. After shifting to B gear, the engine generates a counterforce to assist in deceleration, avoiding the risk of skidding or brake fade caused by frequent braking. I've tried it in rain and snow, and controlling the speed was much easier without feeling the car wobbling. Additionally, under the hybrid system, the B gear can also slightly recover energy, enhancing overall stability. I recommend fellow drivers practice using it more, such as switching when exiting highways or traveling in mountainous areas. The operation is simple: just move from D gear to B gear position while driving. With gradual adaptation, driving confidence will multiply. Understanding this small feature better can help reduce potential hazards.

Using B mode in the Leiling can help save some fuel and protect the mechanical components. During deceleration, the engine braking regenerates electricity back to the battery, slightly reducing fuel consumption. I switch to B mode when driving in suburban areas, going downhill on bridges, or in stop-and-go traffic, feeling the engine assist in deceleration, providing a smooth experience without stressing the braking system. The hybrid design makes it more intelligent, and long-term use can extend the lifespan of the parts. It's easy to get the hang of the operation, and you can switch modes anytime.

As a 2021 Corolla owner, I frequently use B mode for daily commutes and trips. For instance, when going downhill, shifting to B mode automatically engages engine braking to assist with deceleration, avoiding sudden braking. Switching to B mode before traffic lights ensures smoother transitions in traffic. During weekend countryside drives, it effortlessly maintains speed control on slopes without panic. The operation is intuitive with clear gear position markings, requiring no specialized knowledge. This thoughtful feature effectively reduces brake wear. After several uses, it noticeably enhances driving confidence.

As a novice driver of the Leiling, I explored the use of B mode. It's designed for long descents or deceleration scenarios, where the engine helps maintain a stable speed rather than relying solely on brakes. Try shifting directly on gentle slopes, and practice a few times to get the rhythm: after switching from D to B mode, the engine intervenes to slow down, preventing wheel slippage. This reduces the frequency of brake usage, making brake pads last longer. After driving a hybrid, I found this design very practical, especially for beginners practicing on mountain roads, as it boosts driving confidence.
