Nobody expected the same battery to tell two such different stories. One Tesla Model Y variant packs 78.4 kWh and delivers a claimed 659 km on the CLTC cycle. Another, the rear-wheel-drive Long Range, uses the exact same pack and reaches 821 km. That's a 162 km gap — nearly 20 percent. The new figures surfaced in a Chinese vehicle catalog that grants tax exemptions.
This is the next chapter after the model's registration in July. Back then, documents revealed all-wheel drive, a 176 kW front motor — about 239 hp — and a 291 kW rear motor, roughly 396 hp, plus 21-inch wheels and a 250 km/h top speed. Tesla hasn't officially confirmed the Performance name yet, so adding up the two motors' outputs and presenting the total as a confirmed system figure would be premature.
That 659 km figure says a lot about how this car is positioned. China's current lineup includes the Model Y Long Range RWD at 821 km CLTC, the all-wheel-drive Long Range at 750 km, and the six-seat Model Y L at 751 km. Do the math, and the upcoming performance version trails the long-range rear-drive car by about 19.7 percent, and the current AWD by roughly 12.1 percent.
It's not about a smaller battery. The filing lists the same 78.4 kWh capacity and the same 448 kg pack weight. Curb weight climbs to 2,027 kg — 35 kg more than the current Chinese Long Range AWD. Add wider 21-inch tires and a punchier dual-motor setup, and the priority inevitably shifts from maximum efficiency toward performance. The variant measures 4,796 x 1,920 x 1,611 mm on a 2,890 mm wheelbase.
Pricing hasn't been announced. In China, the standard Model Y starts at 263,500 yuan — around $37,500 — while the six-seat Model Y L starts at 339,000 yuan, about $48,300. One thing is already clear: Tesla is now splitting its lineup not just by drivetrain, but by range and purpose too.
Meanwhile, the competition has gotten noticeably tougher. The Xiaomi YU7 offers up to 835 km CLTC, and its base version launched at 253,500 yuan — 10,000 yuan cheaper than the base Model Y. Within the Model Y family itself, expansion is happening in the other direction too: the longer six-seat L version is already serving as a family-friendly alternative to the standard body.
The timing is a sensitive one for Tesla. In July, the company sold 27,249 vehicles in China — down 32.91 percent year over year — with the Model Y accounting for 25,158 of those units, or more than 92 percent of local deliveries. So Performance won't just be the quickest Chinese Model Y ever built. It will have to carry the very model line that's currently propping up nearly all of Tesla's local demand.
Two key unknowns remain before launch: price and a confirmed system output. Range, though, is already settled — buyers chasing that 250 km/h top speed are giving up roughly one-fifth of the distance offered by the 821 km Long Range.
