If you’ve got an extra $10,000 hanging around and were thinking of buying a new Tesla Model S, you might be interested in an upgrade company CEO Elon Musk just announced: “Ludicrous Mode,” an improved acceleration that brings the dual motor version of the car from zero to 60 mph in just 2.8 seconds.

Musk announced the upgrade option during a call on Friday, which is a 10% acceleration bump from the previous model.

It’s a “pretty awesome improvement,” Musk said, according to Bloomberg, calling the 1.1 g’s of acceleration “faster than falling.”

There’s an option for a $3,000 upgraded battery pack as well, which gives cars 15 more miles of range than before.

Tesla noted that its planned Model X crossover vehicle is on track for deliveries in two months and the Model 3, the planned mass-market car, in a bit more than two years, the company said.

The Model X will also have Ludicrous Mode available. Though its acceleration speed hasn’t been set yet, Musk says it’ll take about three seconds to get from zero to 60mph, according to MarketWatch.

No one was quite sure what Tesla would announce today, after the company sent out emails to alert the press yesterday, though Musk clued in followers that it would pertain to the Model S:

“I have no idea. We are just trying to make awesome cars,” he said during the call.
