Do newer cars automatically raise RPM when realising clutch
Discussion
Do modern (2016+) newer cars automatically increase rpm when pulling away?
I was driving a friend's Peugeot 308 diesel and noticed as I was releasing the clutch the revs would increase slightly on their own. I naturally set the RPM to 1100-1200rpm when setting off in my car but found in his car I would end up revving up a bit too much because the car was already doing it! On a steep hill in traffic you could crawl forward just on the clutch without touching the accelerator. In my car it would stall instantly 😂

Yes, worst ones for it are late diesel Fords. It frustrates me as it will accelerate clutch wear over time. Diesels are more than capable of pulling away on tick-over - even on steep inclines - so it seems completely unnecessary.
It's not completely unnecessary, they raise the revs to protect the DMF, MK3 mondeos were terrible for it, after coming from the 1.8TD in the MK2 that you could drive away without touching the accelerator the MK3 2.0tdci's would just stall for fun, the ecu would not allow the revs to dip below a certain level and would stall the engine so it didn't shake the DMF to bits, it was really annoying until you got used to it eventually.MrGTI6 said:

Seriously? The impact is absolutely tiny. Unless you want to launch every time at 0.1m/s2. OP - it's called Feed Forward Launch. A general Quality of Life improvement for customers. Works well.

My work van -Renault -sits with about 1800 rpm, clutch in and in gear, really irritating at traffic lights etc.
You could try not having the clutch in and in gear at traffic lights. Drive properly and the vehicle may behave better. It, or at least important bits of it, will certainly last longer!PGN said:
I didn't know about this. Another "improvement" that takes away control and designed to allow those who can't drive properly to make less of a mess of it while preventing those who can from doing it properly. My pet hate is cluch delay valve - hateful!
Have you taken the synchros out of your gearbox too? Presumably you want a manual choke, carb, points etc for a petrol engine.Cliftonite said:
