Is it a problem if there's a burning smell when revving the engine uphill?

[DiCora]

Yes, it is a problem. When this situation occurs, you should go to a repair shop for inspection as soon as possible. This is most likely the smell of a slipping and burning clutch plate, which commonly occurs in manual transmission vehicles. Since manual transmissions rely on the friction of the clutch plate to transmit power, when the clutch plate is excessively worn, the friction weakens. Therefore, when the engine's power output is too high, the clutch plate can overcome the friction and start slipping, causing it to overheat and produce a burning smell. More details are as follows: 1. It could also be a tire issue: Apart from the aforementioned clutch plate problem, it might also be an issue with the tires. When driving uphill, the front wheels' grip decreases, and heavy throttle can easily cause the tires to slip and spin. When the tires spin, they will inevitably produce a burning smell. 2. Solution: If you encounter this problem, there's no need to panic excessively; simply ease off the throttle. If the vehicle frequently drives on uphill roads, it's best to replace the drive wheels with tires that have better grip.
