Like most manual transmission cars, my 2018 Subatu WRX Premium lags RPM when I start out in first gear. Why does this happen? And, is this okay? ---

I have no idea what you mean . Second , a 2018 has a warranty so ask the dealer and also show them what you think is wrong. ---

I also don’t understand what you mean. Please explain it in different words. ---

Thanks for your reply and interest. Let’s see…a more detailed description. When the car is idling and I put the gear shift in first gear, I notice that when I engage the clutch and press the accelerator, the engine RPMs first dip/lower before the engine increases RPMs. This occurs no matter how slowly or quickly I engage the clutch. If I want a VERY fast 0-60 start, this does not occur. But, the WRX is my daily driver; I’m not “racing” it around town. I’ve noticed this same engine RPM down-lag-at-initial-start-from 0.0 MPH on all my previous manual transmission vehicles. Is this me or is this normal on most/all manual transmission cars. Regards, Warren Rubin ---

I thought manual transmission cars were peppier? isn’t that why some people don’t like automatics? Confused… ---

To me it just sounds like you are not pressing on the gas peddle enough. It takes coordination of the left and right foot to accelerate smoothly with a manual transmission. ---

Yeah, that’s how all manual transmissions work. Slight dip in rpms as you start letting the clutch out. ---

I’ve noticed this same engine RPM down-lag-at-initial-start-from 0.0 MPH on all my previous manual transmission vehicles. Is this me or is this normal on most/all manual transmission cars. different cars. same driver. hmm. do the math
