    Unintended acceleration in 2024 MG4 Trophy LR

    You know, I'm wondering - the car I test drove would have been one of the very first MG4s in the country. And I've just been looking at photos (in road test reviews) of the MG4 interior which show the pedal spacing to be just fine - and hard to imagine how there could be interference when...

    Unintended acceleration in 2024 MG4 Trophy LR

    I've driven (literally) scores of different cars over the years, and only ever recall making this observation with the MG4. Also, I do vaguely remember watching, much more recently, one of those YT comparisons of EVs (Carwow/WhatCar/Electrifying etc.) in which someone mentioned an unusual...

    Are you lecturing me?

    Unintended acceleration in 2024 MG4 Trophy LR

    Yes, coming from a Yaris, I did find the angles as I described, so it was definitely a concern that this could cause problems - especially as I intended to run both cars. Operator error or not, it's a bit late if you're hospitalised because of differences in driving ergonomics. The point is...

    Unintended acceleration in 2024 MG4 Trophy LR

    Well, I've driven an MG4 only once - a test drive in 2022. I remember being alarmed at how easy it was to press both accelerator and brake pedals at once when trying to brake. In fact, I'm sure it was a contributary factor in deciding to back out of the purchase. I think the problem is that...

    MG4 X Power Vibe/Hum 65 to 75mph

    No, just play in YT and hold down the left mouse button with the cursor in frame. Very handy, at times.

    MG4 X Power Vibe/Hum 65 to 75mph

    Maybe it's to due with flat spots (from standing for months before sale) exciting the real problem, which is (front) driveshafts set at an excessive angle - plus the type of CV joints used in those driveshafts. A perfect storm? That might explain, at least to a degree, that (seemingly)...

    New MG4 coming? (merged)

    Here's the report from the Electric Viking: For me, it's a few steps back in terms of looks, and I doubt I'd be interested in buying one. And I think the weight loss may be down to the new LFP battery (made by a no-name company, seemingly). Will they be selling off the old ones cheap to...

    MG4 X Power Vibe/Hum 65 to 75mph

    Sounds like they're replacing tripod-type CV joints with something a bit more sophisticated.

    Simulated gearboxes for EVs

    It's not that IC engines need gearboxes because they're (inherently) inefficient, it's because they are intrinsically constant-torque (with torque tailing off at very low speeds and very high speeds because of the practicalities of implementation). So a gearbox is needed in order that the...

    MG4 X Power Vibe/Hum 65 to 75mph

    Very interesting.

    Reliability worry

    Hmm...

    MG4 X Power Vibe/Hum 65 to 75mph

    Yes - that corresponds to the findings described in Post 640. Three times the rotational speed - which prompted me to comment that maybe the root cause is something to do with a tripod-type CV joint.

    MG4 X Power Tyre Upgrade

    Especially as the vibration has been measured as being 3x the roadwheel rotational speed. Unless there are 2 separate sources, and 2 different vibrations...

    MG4 X Power Tyre Upgrade

    I wonder if this is the same vibration as in the Xpower?

    MG4 X Power Vibe/Hum 65 to 75mph

    If it's to do with rear suspension, we know that the Xpower rides higher than the others - has anyone noticed any difference in the vibration with the car carrying a heavy load in the rear (two large adults and/or stuff in the boot)?

    I will never buy another MG ever again ?

    Xpower is so tempting!

    I will never buy another MG ever again ?

    I read it as the first car was a non-Xpower MG4, then changed to an X-power after experiencing vibration.

    I will never buy another MG ever again ?

    (My Bold) You had the vibration problem with a non-Xpower?

    MG4 X Power Vibe/Hum 65 to 75mph

    Well, both sources of mechanical disturbance would serve to excite a resonance, though I'd agree that out-of-balance would be proportional to the square of the rotational speed, so is more likely to behave as seems to be commonly the case. Does the vibration disappear at higher road speeds?
