Tesla has revised the dimensions it publishes for the Model Y L in China. A comparison of the April edition of the owner's manual against the current one shows four measurements reduced, all of them describing how high the car sits, and none of them describing how long it is.
Tesla announced nothing. The change was found by reading the two manuals side by side, and it arrives weeks after Model Y L owners in China began reporting that the rear of the car was settling.
What moved, and what did not
| Measurement | April manual | Current manual | Change |
|---|---|---|---|
| Overall height | 1668 mm | 1664 mm | -4 mm |
| Ground clearance, unladen | 169 mm | 166 mm | -3 mm |
| Ground clearance, fully loaded | 122 mm | 118 mm | -4 mm |
| Front overhang | 896 mm | 889 mm | -7 mm |
| Wheelbase | 3040 mm | 3040 mm | unchanged |
| Rear overhang | 1040 mm | 1040 mm | unchanged |
The pattern is the useful part. Wheelbase and rear overhang are fixed by the body structure and they did not move. Every figure that did move is one a car's ride height determines — how tall it stands, how much air sits under it empty, and how much sits under it loaded. Front overhang shortening by 7 mm is consistent with the same thing, because the measurement is taken to the ground.
What owners reported first
Owners in China began reporting in late August and early September that the rear of the extended-wheelbase Model Y L was sagging, which TeslAnt covered in the rear-suspension reports from Chinese owners. The symptoms described were a closing gap between the rear tyres and the wheel arches, uneven tyre wear, and a change in how the car handled.
Tesla has been replacing rear springs under warranty on cars that measure below tolerance. At least one owner has said the sag returned after the replacement.
What this does not establish
A revised manual is a revised document, not an admission. Tesla has not linked the two things, has not said why the figures changed, and has issued no recall or service bulletin about the dimensions. There are at least two readings, and the available evidence does not separate them.
The first is that the original figures were wrong, or were taken from a pre-production car, and the manual has been corrected to match what leaves the factory. The second is that something about the car's standing height genuinely changed — a spring specification, a suspension tune — and the manual follows the hardware.
What can be said is narrower and still worth recording: the published numbers now sit lower than they did, the reduction is confined to height-derived measurements, and it happened while owners were complaining that their cars were sitting low.
Europe has no Model Y L to check this against
Every figure above comes from the Chinese-market manual. The Model Y L is not sold in Europe, though its configurator code has already appeared in Europe's systems, and its EPA range was certified above Tesla's own configurator figure in North America. European buyers have no car to check against these numbers yet. If the Model Y L does reach Europe, the spec sheet it arrives with is now a different one from the spec sheet it was launched with.
