The Model S P100D with Ludicrous mode is the third-fastest accelerating production car in existence, going from 0-60 mph in 2.5 seconds in max power mode. Meanwhile, the Model X P100D (Tesla's electric SUV) with Ludicrous mode hits 60 mph in 2.9 seconds and travels up to 289 miles on a single charge.

"These are really profound milestones and I think will help convince people around the world that electric is the future and it's time to move to sustainable transport," Tesla CEO Elon Musk said during a conference call today.

Existing owners of Tesla's electric vehicles are able to swap out their 90 kWh modules for the new-and-improved battery. At the onset, Tesla plans to produce about 200 packs per week and they're available to order today. Existing P90D Ludicrous owners can upgrade to the 100 kWh pack for $20,000, while those who have ordered a P90D but not seen a delivery yet can snag the new pack for $10,000. A new Model S costs up to $134,500 and a Model X tops out at $135,500.

"While the P100D Ludicrous is obviously an expensive vehicle, we want to emphasize that every sale helps pay for the smaller and much more affordable Tesla Model 3 that is in development," Tesla's blog post reads.

Rumors of a 100 kWh battery rumbled across the internet earlier this month, when Dutch regulators approved 100D and P100D versions of the Model X and Model S.
