Tesla confirms the 75 kWh battery pack is coming to the Model S [Updated]

The California Air Resource Board (CARB) updated its website to surprisingly add an unannounced new Tesla Model S 75D to its list of vehicles eligible for single occupant carpool lane stickers. While Tesla unveiled a new drivetrain powered by a 75 kWh battery pack for the Model X last month, the automaker didn’t want to confirm the same battery option for the Model S.

As of now, the smallest battery option for the Model S is a 70 kWh battery pack (available with RWD or AWD) and the 75 kWh is not available as an option on Tesla’s website.

But the 75 kWh is one of the only two options for the Model X, the other being the 90 kWh battery pack, both are only available with the all-wheel-drive powertrain.

Unless CARB made a mistake, it would mean that Tesla is about to introduce the 75 kWh battery pack to the Model S.

We asked Tesla if they have any comment on CARB’s update and we will update if a representative gets back to us.

Update: A Tesla spokesperson confirmed that Tesla will indeed introduce the 75 kWh battery pack to the Model S lineup without disclosing a timeline.

Currently, the 70 kWh RWD option is rated at 234 miles of range on a single charge and the AWD option boost the range to 240 miles. A 7% increase in energy capacity a 75 kWh pack would bring could potentially increase the range of the RWD option to 250 miles and the AWD to 256 miles.
