Sluggish accelaration

[skyblue46]

hello there!
I recently bought 2018 Mazda cx-5 , 2.5L Petrol (85,000km), but noticing the accelaration is sluggish 0-50kmph , but after reaching 50km speed it is smooth accelaration. feeling difficult with merging onto highways unless im really pressing the accelarator hard (both hot and cold days - anytime). what can be done?

They are a little sluggish off the line but perform better on the highway. If you can learn how to use the power band it might help you achieve a more acceptable ride

I find the exact opposite. Off the line performance with the 2.5, FWD is impressively quick, but only adequate at highway speeds.

Do you have an engine light?

Well I a CX-50 AWD the extra weight may mean a difference. However I cruise pretty easily on the highway achieving 80 to 100 . Not that I typically drive that fast

Yes true. Pre facelifted FWD Mazda 6, CX5 is 3200lb-3400lb. At this weight, and without the driveline loss inducing, heavy AWD system to lug around behind you, these cars can be quick off the line.

Same here. IF I am sedately using the throttle.

But if I keep the RPMs at the shift points in the 4000-5000rpm range, the car moves right along. In the "Sport" mode and manual shifting, there's not much sluggishness, particularly if the RPMs at the shifts are kept high.

There are a couple of steeper on-ramps to the highway, where I live, where I'm putting my life in the hands of every car coming along ... if I fail to get up to speed quickly. And so, it's "Sport" mode and manual shifting with shifts over 5000rpms, to ensure any lollygaggers in the RH lane aren't much of an issue and I can merge-in easily. Makes all the difference, even uphill on such steeper onramps.

Something to try.


Also, at more than 50Kmi, it's high time to do a deep cleaning on the throttle body assembly, to ensure there isn't any crud affecting easy operation of the butterfly panel inside the throttle body. If you've experienced the car's aggressive attempts to shift in order to squeeze out the last ounce of fuel economy, you might find that much less pedal effort is required for the car to downshift. Helps to be a bit more assertive with the throttle when you actually intend to quickly accelerate, instead of helping the car to learn you're completely willing to sedately dodder along with it shifting down to ~1300rpms or so at every opportunity. (I hate that aspect of the car, but with a 'nimble' throttle it's easy enough to jump down a gear for more-brisk acceleration when preferred.
