Does your Volvo automatically match the revs on upshifts?

9000rpm · Aug 27th, 2019, 16:19

On my 2006 v70 d5 manual the other day I noticed the revs hanging up on upshifts. I thought it was a fault. But on further investigation the rpm hold was different in each gear and speed. I then noticed what the revs were holding at was the exact rpm for the next highest gear. So all you had to do was let the clutch up with no throttle needing to be applied and the next gear was perfectly smooth as the rpm was exact match for the gear! I'm sure it didn't used to do this! It's not the fastest change doing it this way but it seems the kindest on the transmission and clutch.

I've tried searching for this feature on the internet but I find nothing.

Anyone else noticed their volvo does it?

Yup. My 06 V70 D5 did it. The 09 C30 1.6 petrol doesn’t... once you get used to it, driving a manual without it is quite unpleasant.

I don't notice it on mine and regularly drive 2 other vehicles that defiantly don't. Find no difference between them.

Perhaps I had only driven the D5 for so long I became reliant on it!

Haven't noticed this, but mine's a pre-facelift V70 D5 - possibly something brought in on the later P2's? Although I'll pay attention next time I'm out in it!

So I've been playing with volvo gear change more . I wondered if you leave your foot on the throttle slightly do the revs still hold for next gear. They do! And as it turns out if you accelerating gently you don't have to take your foot off the throttle at all! It still let's the revs drop to the correct amount! You change gear and let clutch up and it's super smooth and you are accelerating again but without lifting off the throttle. A normal set up the revs would flair as soon as you dip the clutch as the load is off the engine but this drops rpm so it must be taking over control of the throttle. Gear changes are super smooth! Such a funny feature not bothering to mention!
If you are accelerating say more than 20% then the revs will flair as it must be a safety feature so you have acceleration if the system goes wrong.

I have never noticed this with my VEA D4.

Although if it was to do something odd and unexpected then according to a recent letter from Volvo I should probably assume it's about to catch fire and report ASAP to a dealer.

This is something I have done for years in all my manual cars, although it wasn't done automatically by the car. It's called a 'sustained rev or rev matched' gear change. As you have discovered it provides a beautifully smooth change and is a lot kinder on the transmission. Takes a lot of practice at first but once perfected you can change gear without your passengers doing the 'nodding dog'. Just a question of 'ease or squeeze' depending on wether you are going up or down the gears, and you are right you don't take your foot of the accelerator.

A lot of new cars now feature this to some degree.

this ISNT taught when you are being taught how to drive? its a Basic step of Changing gears.
i guess not given the comments,

ah well with the price of clutches now i guess garages must love the total lack of any mechanical sympathy & understanding of "nu-drivers"

I wouldn't say it matches the revs, but my 850 T5 hangs the revs a moment whilst you change gear, makes for a smoother transition.
