Electric car company Tesla Motors today announced a new upgraded battery pack for the Model S sedan.

Customers will be able to buy a 90-kilowatt-hour 19-hour battery pack for $3,000, Tesla Motors cofounder, chief executive, and product architect (and PayPal cofounder) Elon Musk said during a company conference call today.

The Model S P85D is also getting faster. Thanks to a new “ludicrous mode,” Musk said, the car will be able to go from 0 to 60 mph in 2.8 seconds. Tesla’s forthcoming Model X sport-utility vehicle will also get the new “ludicrous mode,” although the acceleration time hasn’t been determined yet.

The “ludicrous mode” is basically an extension of the “insane mode” the Model S has been able to do when it goes from 0 to 30 mph, Musk told reporters on the call. Musk described “ludicrous mode” as “your own private roller coaster.”

As for updates to the outside of the Model S, those might not be on the way anytime soon.

“Our focus right now is very much on the X and just getting that done,” Musk said when a reporter asked about product redesign for the Model S.

Tesla today also announced that the Model S with a 70-kilowatt-hour battery will now cost $70,000.
