    Collected today - bitter sweet experience

    3 million miles ! Maybe that's how long it takes for the parts to wear in and the vibes vanish . Sorry, couldn't resist 🤡

    MG4 X Power Vibe/Hum 65to75mph

    Considering it's China, that may well be their fate o_O

    Well this sucks (XPower crash tested) 🙄

    I guess that would be ok if the inner structure and subframe hasn't moved. Bumper, light and wing obviously but possibly the bonnet and door salvageable by a skilful metal tickler ? If there's no airbag pop and the damage is confined to the external cosmetic panels I don't think I would be...

    MG4 X Power Vibe/Hum 65to75mph

    Is it not a little more than 2 inches ? Plotting an imaginary line from the centre of the driveshaft nut it looks pretty offset. These cars have a noticeable positive caster though, so maybe its misleading with the strut on full droop. I've never heard or felt any drone from driveshafts on any...

    MG4 X Power Vibe/Hum 65to75mph

    So SAIC plan to fit a 'steering damper' to resolve this issue ? That does sound like a typical MG response to the problem, cheapest band aid fix rather than addressing the root of the fault. The vibration must be coming from rotating components, why are they pi$$ing around with the steering ?

    MG4 XPower. This never grows old 🤣

    That's the main thing that I would appreciate about the XP I think. The entitled A holes who storm up behind you in the outside lane when you're quite legally overtaking and expect you to scurry out of their way :rolleyes: Sometimes you can leave them in your dust in the SE, rather depends on...

    Think this issue might defeat even my 8mm ☺️

    MG4 X Power Vibe/Hum 65to75mph

    Head scratcher is there's plenty of space towards the front of the car to mount the motor further forward. Were they trying to keep major mass within the wheelbase and didn't consider possible side effects ?

    MG4 X Power Vibe/Hum 65to75mph

    Anyone brave enough to pop a clip from one of the CV joints to check the grease levels ? After finding all 4 brake calipers completely devoid of grease on mine, nothing would surprise me. Still think its the extreme forward angle of the driveshafts though, this means that the balls inside the...

    XPower Real World Range - owners feedback

    The great thing about electric motors is that fitting a high output one ( or two ) doesn't hit efficiency like a large capacity ICE does. The wider tyres and losses from the extra gear train coupled with the 150kg weight penalty probably accounts for the x powers range loss more than the total...

    MG4 X Power Vibe/Hum 65to75mph

    As bricktop mentioned, manufacturers always tend to design their powertrains so driveshafts end up as straight as possible. Yes, a constant velocity joint is designed to transmit rotational power through an angle but there's still losses and wear associated with that. Makes much more sense...

    MG4 X Power Vibe/Hum 65to75mph

    Even if the extreme driveshaft angle is not the cause of the vibration it still seems like a really odd thing to sign off. There will be constant parasitic losses in all 4 joints because the balls slide fore and aft as the joint rotates at an angle. Maybe it wont amount to much but it will be...

    MG4 X Power Vibe/Hum 65to75mph

    Demonstrates how the ball cage has to slide when in motion to accommodate any angle off dead straight. Maybe 65 to 75 is the wobble frequency that sets it on the vibe ? Hopefully more simple though as you say :confused:

    MG4 X Power Vibe/Hum 65to75mph

    Yup, inner and outer CV joints will be constantly working, and despite their name I'm not sure thats a good design decision. You may well have identified the cause, only trouble is there's not much that can be done barring a clean sheet redesign :confused:

    MG4 X Power Vibe/Hum 65to75mph

    Ok, so that's that theory blown out the water then :) can you take a pic of your front drivetrain ? Curious to know what it looks like and if its just the trophy unit with no changes.

    MG4 X Power Vibe/Hum 65to75mph

    Pretty much speculating re motor ;) Can't remember who but someone posted specs of the 3 motor variations MG currently use, 170, 200 and 240 BHP IIRC, I'm assuming uber cost conscious MG just threw the 240 in the rear and the 200 in the front, don't remember one with a decoupling geartrain...

    MG4 X Power Vibe/Hum 65to75mph

    The belief the front motor doesn't decouple or that current is induced when moving magnets near coils ?

    MG4 X Power Vibe/Hum 65to75mph

    Watched a munro live vid on the youtube where they estimated a $100 cost to Hyundai for fitting a decoupler in the front motor assembly. They also reckoned it made the drivetrain 6 to 8 % more efficient, equivalent to saving $600 in several kWh of battery capacity they didn't need to install (...

    MG4 X Power Vibe/Hum 65to75mph

    I believe the x power just uses one of the standard perm mag motors on the front, no fancy decoupling mechanism in the reduction box. If the motor is idle but still being spun by the cars forward motion, the magnets will still be causing electrons to flow in the field coils 'cogging' I believe...

    Xpower as a hot hatch - cornering in particular

    What's the default power and regen setting on the x power ? Full beans and max regen would be my preference but I'm guessing the fun police haven't made it so ?
