Those hoping to get epic range out of Tesla’s new Model 3 sedan may be disappointed by a new revelation from Tesla CEO Elon Musk: it won’t have the 100kWh battery pack that’s currently available in the Model S and Model X.

The Tesla Model S 100D has an estimated range of 335 miles, while the Model X 100D can go 295 miles. Tesla announced at the reveal of the Model 3 that it would have a range of at least 215 miles in base trim.

The revelation was made in a tweet by Musk earlier today, when he also revealed that there are no plans to equip the Model S or Model X with a battery pack larger than 100kWh — though a future Tesla big rig (definitely) and pickup truck (maybe) will be so equipped.

The Chevy Bolt, the main all-electric competitor for the Tesla Model 3, gets an EPA-estimated 238 miles of range from its 60kWh battery pack — the only size GM offers.
