New Tesla Model Y 2025: Batteries and Power Unveiled

Drop by drop, the technical specifications of the new Tesla Model Y 2025, presented on January 10, are being revealed.

This is probably the most interesting information for Tesla enthusiasts: the size of the batteries. As usual, nothing has leaked from the Sino-American manufacturer (launches have traditionally been announced in China, Tesla’s first market for years). That was without considering the permeability of secrets in China, where everything leaks deliberately.

In a sense, all information about the upcoming style of the new Tesla Model Y version 2.0 has leaked from China. Today, the technical specifications are also available. We can start with the dimensions: the wheelbase remains unchanged at 2890 mm, while the length is 4797 mm (+47 mm), the width 1920 mm (-1 mm), and the height 1624 mm.

Small batteries?

The total weight of the Tesla Model Y 2025 has increased only slightly: an average of +10 kg (from 1921 kg for the Rear-Wheel Drive, to 1992 kg for the Long Range All-Wheel Drive). Considering that the glazing is now thicker (and thus heavier) to reduce ambient noise in the cabin, and that the equipment is more generous, there is no doubt that the battery capacity has increased only slightly.

Another argument supporting this thesis: the 400-volt architecture has not changed either. And this is a very troubling aspect: the Tesla Model Y 2025 is already 4 years old in terms of design, and is therefore not up to date…

The Model Y Rear-Wheel Drive retains the motor from the current Long Range Rear-Wheel Drive, with 330 horsepower. It accelerates to 100 km/h in 5.9 seconds. Its battery remains a CATL Lithium Iron Phosphate (LFP) production of 62.5 kWh. Thanks to aerodynamic and electronic improvements, the combined Chinese CLTC cycle consumption drops by 1.1 kWh per 100 km, resulting in an increased range of 39 km (593 km). In Europe, a combined WLTP range of about 480 km can be hoped for, definitely below 500 km. Disappointing again for such a highly anticipated model.

The Long Range All-Wheel Drive version would not see its power change: 158 kW at the front and 220 kW at the rear, but the acceleration would be more energetic. The 0-100 km/h time is now 4.3 seconds, compared to 5.0 seconds previously. As for the battery, it is said to have a capacity of 78.4 kWh, with a Chinese range increase of 31 km. In Europe, the final range would therefore be around 550 km. Again, the competition performs much better…
