Guess I was in minority to watch it all ? but regardless, the end results seem to confirm what many people are seeing - not only is the range of the SR and Trophy obviously different due to battery size, but the efficiency is also different with SR being better.
Whether that's due to the different battery chemistry or the spoiler, a combination of both, or perhaps something else entirely I don't know.
I'd like to see similar chart with the LR, to see which one the LR is closer to, but I suppose it's academic as we can't change our battery chemistry, and I doubt if anyone's gonna yank their spoiler off to eek out a few more miles.
Bottom line is comparing SR and Trophy range is pointless, it ain't apples with apples, might as well be comparing against a Tesla M3
Hence why I wish people would rem to mention which model they're driving when quoting range and efficiency figures, as I for one can't rem what ye all have ?, Please?
I think the fact that it's a hatchback is the fundamental problem as speed increases.
No coincidence that the model 3 and classic Ioniq with their streamlined bums can do much better at national limits, less turbulence and low pressure areas at the rear.
Although I accept your logic, I don't believe it's shape is the only reason.
To give example, my better half drives a Kia eniro that - on paper at least, has similarities to MG4, same battery size, power and range,
But the Eniro defo could not be considered an aero shape (much bulkier than the 4) but in identical journey comparisons (we sometimes swap cars) the Kia efficiency drops much less at the higher speeds than the MG, while at slower speeds the difference is minimal.
I can't explain why, and hard to see spoiler make such a difference (though I do accept Kia is dearer car and well known for having better range/eff than most, so better drivetrain or electrical efficiencies could be a factor)
Would be great if someone who has a LR might tell us if they think their eff figures are closer to the SR or Trophy??
