Why Does Stepping Harder on the Accelerator Cause a Burning Rubber Smell?

[StBrody]

Stepping harder on the accelerator causing a burning rubber smell can be attributed to the following reasons: Excessive Throttle Input: This situation is most likely caused by applying too much throttle during semi-engagement. For manual transmission vehicles, excessive throttle during semi-engagement can cause the clutch plates in the transmission to heat up rapidly, resulting in a burning smell inside the car. Additionally, if the handbrake is not fully released while climbing a slope, the brake pads will continuously rub against the brake discs, and the high temperature generated will naturally produce a burning smell. Therefore, when going uphill, it is advisable to avoid pressing the accelerator too hard during semi-engagement to prevent damage to the clutch plates. New Rubber Components: If the vehicle is new, a slight burning rubber smell under the hood is normal because the rubber components are new and will emit a stronger rubber odor when exposed to heat. This issue will naturally disappear after some use.
