Tesla’s Latest Model X Comes With Higher Battery Density And More Powerful Motors

Tesla’s recently refreshed Model X has a higher battery energy dendsity and more powerful motors, according to an EPA specification sheet that wasn’t previously available.

While we knew that changes had been made to the latest Model X, Tesla had been less than clear on what had really changed.

Now, new data found in a new EPA datasheet outlines exactly what’s new. As Electrek points out, none of these numbers are necessarily from Tesla, but they’re the best we’ve seen yet.

First off, it shows an important improvement in battery pack-level energy density from 165 Wh/kg to 186.21 Wh/kg.

The overall energy capacity went down from 103 kWh to 100 kWh.

The result isn’t the loss of range that you might have expected. Because there are fewer batteries, the car is 200lb lighter than the previous model as a whole. That all helps to make the car easier to move which in turn means less power is needed. The results are similar range figures.

The voltage for the Tesla Model X battery pack has also increased from 360 volts to 410 volts, the report notes.

In terms of motors, Tesla has switched to “AC permanent magnet motors and increased the power to 243 kW in the front motor and 248 kW in the rear motor.”

It isn’t immediately clear what difference in the real world driving of the Model X we can expect these changes to make, although the lower weight is always beneficial when cornering etc.
