The science says they are packing more batteries than the vehicle needs, but the consumers say otherwise.
All manufacturers, Tesla included, consistently find their long range versions significantly outselling the short range ones.
In Tesla’s case it got to the point where demand for short range versions was so low, it was cheaper in some cases to only make larger range versions and limit the range with software. Rather than maintaining multiple production lines.
In the late 90s GM’s made the first moderately popular modern production electric car in North America. The initial version had a 55 mi range on traditional lead acid batteries (when measured using the 2019 EPA standard protocol, it was advertised as having a 78 mi range using the protocol at the time). That was enough range to meet the daily driving needs of 98% of the population. They tried selling it with the message that’s enough for your needs, it didn’t sell well. Later versions used NiMH batteries and had almost twice that, it still wasn’t a big seller.
Both then and still today, the lowest range EVs from all manufactures, which have at least double the original EV1 range, consistently and significantly undersell the longer range models because consumers think they need to have hundreds of miles of range so that they can take the occasional unplanned road trip.
The need to significantly over-provision the range on an electric vehicle is due to consumer demand not misleading marketing.
