A couple days ago, we reported on Tesla launching a paid software update for its Model 3 Long Range Dual Motor line, aimed at improving acceleration. Today, rumors surfaced that the sedan might get a larger 100-kWh traction battery sometime in 2020.
A Model 3 owner discovered the various configurations of the car listed in the software code, including a previously unannounced spec with an extra-large 100-kWh battery. Note that, while Tesla never explicitly states the battery capacity, preferring to provide range estimations instead, multiple documents suggest that the farthest-going Model 3 Long Range packs a 80.5-kWh battery, out of which it uses between 75 and 78 kilowatt-hours.
A test drive performed by an enthusiast a while ago showed that the Model 3 Long Range could cover 975 kilometers (605 miles) using up only 66 kilowatt-hours of battery juice. However, the driver took care to keep the speed down to 32-48 km/h (20-30 mph) at all times. A range-topping Model S went faster in another experiment and made it as far as 1,078 km (670 miles) exhausting 98.4 kWh out of its 100-kWh power storage.
Another interesting find indicated that the Model 3 Performance could be getting Ludicrous Mode in the coming year, which would reduce its 0-60 mph (0-97 km/h) sprint time even further from the already impressive 3.2 seconds. Elon Musk himself has repeatedly stated that this was possible.
