We all knew it was coming, but now Tesla has European approval for the 100kWh battery pack and it should soon make its presence felt in the Model S and Model X. Get ready for even more power and, crucially, a 380-mile range.

It’s slipped quietly into the European database that Dutch authority RDW controls. But, like all things Tesla, nothing stays quiet for long. The information is freely available to the public and Kenteken.TV has gone to the trouble of digging for Tesla’s entries and publishing the information on Reddit.

The battery pack is limited to the Model S and Model X, so there will no supersonic Model 3 just yet. We’ll have to wait and see what it means in terms of performance, but the Model S P90D has already run a series of sub 10-second quarter-mile times and Tesla itself quotes a figure of 10.9s, with a 0-60mph time of 2.8s.

Will it go faster?

So how much faster can the Model S get? Even with a significant power boost, the tires will eventually become the limiting factor in terms of getting the power down off the line. Indeed, that may already be the case. So the P100D should be significantly quicker in terms of rolling acceleration, but don’t expect a significant boost in the 0-60mph time.

Range, then, might be the main reason behind this upgrade. With rival manufacturers working on their own electric vehicles then Tesla is going to have to work harder to maintain its competitive advantage.

If the Fremont company can leave the competition in the shade when it comes to range, that will be enough to keep the Model S, Model X and Model 3 ahead of the game.

A firm idea

Kenteken.TV deciphered the EU Type approval codes to confirm the new model, but we already knew it was on the way. Hacker Jason Hughes caused a stir when he found a P100D graphic on the firmware of his Model S. It rattled Tesla to the extent that Hughes claimed the company attempted to establish a remote connection to his car and delete the pending firmware update.

Tesla boss Elon Musk later hailed the hacker’s work, saying: “Good hacking is a gift.”

It wasn’t quite a confirmation that the P100D powerplant was on the way, but it was all we really needed. Now we know for sure and, yes, we’re looking forward to it.
