Tesla revealed details on its new range-topping versions of the Model S and Model X which are set to get a new 100kWh battery pack.

The company claims that the Model S P100D with Ludicrous mode is the quickest-accelerating current production car you can buy right now, with a 0-60mph time of 2.5 seconds.

The new bigger battery pack also increases the driving range to an EPA-estimated 315 miles and 613km on the EU cycle, making it the company’s first model to go beyond the 300-mile mark and the longest-range production electric vehicle on the market.

Numbers as just as impressive for the Model X P100D with Ludicrous mode as it’s now able to hit 60 in 2.9 seconds and travel up to an EPA-estimated 289 miles and 542km on the EU cycle.

Tesla says that current owners of the P90D Ludicrous versions can upgrade to the 100kWh pack for an extra $20,000 which includes the cost of having their old battery packs recycled. Customers who have ordered a P90D Ludicrous and haven’t yet taken delivery can upgrade to the new spec for $10,000.

The base price for a Model S P100D is now set at $134,500 with the Model X still to be revealed.
