The Tesla Model S 100D and Model X 100D have been confirmed for production, with both cars getting extended battery ranges thanks to new 100kWh battery packs.

Elon Musk confirmed the arrival of the new 100kWh batteries to Autocar UK during a conference call.

The new Model S P100D will be capable of reaching 100kph in 2.5sec, making it 0.7sec faster than a McLaren F1. Now that the Porsche 918 and LaFerrari are sold out, it's officially the quickest car currently on sale.

The upgraded Model X P100D will hit the mark in 2.9sec. Both cars are four-wheel-drive.

Customers in the US waiting for P90Ds with Ludicrous Mode can upgrade their order to P100D spec for $10,000 (Rs 6.31 lakh). Exisiting P90D owners can get their cars to P100D spec for $20,000 (Rs 12.63 lakh) to cover costs of old battery recycling.

Musk said that the drivetrains for both cars will remain the same, with only the larger capacity batteries being new. He also said Supercharger rates would be unaffected, although charge times might increase due to the larger capacity.

The Model S's range increases to 315 miles/504 kilometres under EPA tests and an anticipated 381 miles/609km under NEDC tests (the latter is yet to be confirmed), giving it the largest range for any electric production car. 

The Model X P100D will have a range of 289 miles/462 kilometres according to EPA tests. The NEDC will likely be close to 330 miles/528 kilometres.
