Is it normal for the engine to be very loud and sound like it's resonating when it reaches 2000 RPM?

When driving the 2014 Foton Tunland 2.8S 4WD, there is a noticeable humming vibration in the cabin when the alternator speed is below 1600 RPM. However, once the engine speed reaches 2000 RPM, the humming sound disappears. Could any experts advise on what might be causing this issue?

Hey guys! Does anyone else experience weird noises when their car's RPM goes above 2000? It sounds like a roaring noise, and I feel like it might be an issue with the intake or exhaust!

When the RPM reaches 2800, there's a loud roaring noise, but after 3000 RPM it disappears. What's going on? [Cover face]

I just got a 2013 model with a 1.6 manual transmission. Everything else is fine except there's a loud buzzing vibration sound around 2000 RPM in every gear. Before or after hitting 2000 RPM, it's normal again. Has anyone else experienced this? How can it be fixed? Any advice from the experts would be appreciated.

How can I fix the issue of the engine noise being very loud when starting the Alto 1.0 when it's cold? The sound normalizes once the water temperature reaches 20 degrees.

Hi everyone, I have a 2013 Suzuki Alto automatic. When I start and just slightly press the accelerator, the RPM quickly goes up to 2000. Even when the speed reaches 60, the RPM stays around 2000. What's going on here?

Does your engine also make a loud noise when the RPM reaches 2000? Especially when going uphill, all I can hear is the roar of the engine.

Does anyone else experience their engine roaring at 2000 RPM?

As a new driver, I've only driven the 2019 2.0 model, and I find the acceleration quite sluggish. When I press the gas pedal deeply, the engine needs to reach around 1800-2000 RPM to speed up a bit, and the engine noise is quite loud. Is this normal for a naturally aspirated engine with a CVT? I tried using the DS mode, which seems to provide what I consider normal acceleration, but I noticed the RPM goes up to four or five thousand. My friend's 1.5T Geely doesn't make much noise and feels more powerful.

My Zhilong 2022 model 2.0 has reached 20,000 kilometers. When the engine is cold-started, there's a "dang dang dang" sound at 1500 RPM, but it's gone at 800 RPM. Is it the same for you guys?
