Tesla will introduce a larger capacity battery – 84.7 kWh gross – to power the Model Y L Long Range… and the Performance?
Intrinsically, what more does a Tesla in Performance trim offer? A look and that’s it? Until now, it has been difficult to find other strong arguments, with range in free fall (the worst in the Model 3 lineup, for example, with 528 km compared to 554 km for the entry-level Propulsion). There remain the best accelerations, even if they are not spectacularly superior to those of a Model Y Long Range All-Wheel Drive. Every green light acceleration is not an opportunity for a Formula 1 standing start…
The question of suspension remains, which is firmer and better contains the body movements of a car with a sporty vocation weighing over 2 tons.

Towards a slightly better range?
Tesla seems to have sought a dual solution to the autonomy issue in its future Model Y Performance and Model Y L with an extended wheelbase, currently announced only in China.
For the latter, Tesla has already revealed a more generous battery to maintain a range similar to the Long Range All-Wheel Drive version. This shows that the American manufacturer is aware that range remains one of the key arguments in its commercial discourse.
Thus, the battery modestly increases from 78.8 to 84.7 kWh gross, contributing an additional fifty kilometers in the mixed WLTP cycle. A small increase, you might say? Yet, this could indeed change everything!
Indeed, the new generation of Model Y is subtly more efficient in terms of aerodynamics and energy management. With this new 84.7 kWh battery, the upcoming Model Y Performance should be able to announce in Europe a range of 600 km or more. And that would change everything.
The customer would no longer feel the need to make significant concessions. Because in the 21st century, in the age of electric vehicles, “performance” must now be judged by range and charging power to quickly get back on the road. It is no longer about accelerating to 100 km/h in 3 seconds, since any Chinese car costing €30,000 will soon be able to do that…
