Tesla has introduced a new “Energy Boost” software upgrade for recent buyers of the Model Y RWD, enabling them to unlock additional battery capacity for a fee.
The Model Y RWD has seen numerous adjustments recently, including fluctuating prices and the introduction, and subsequent cancellation, of a “Standard Range” (SR) model with a smaller battery. This model has now been replaced by a “Long Range” (LR) version. When discontinuing the SR model, Tesla revealed that these vehicles had larger batteries than advertised and announced plans to offer software unlocks to extend their range by 40-60 miles for $1,500-$2,000, pending regulatory approval.
These software upgrades are now becoming available to Model Y owners through the Tesla app. However, the actual offerings differ slightly from the initial promises. Some owners are presented with a $1,600 upgrade for “up to 50 miles” of additional range, while others see a $1,000 upgrade for “up to 30 miles.” This falls short of 40-60 miles for $1.5-2k.
Each range estimate has a disclaimer: “Estimates are based on internal modelling and will vary depending on factors like battery age and driving behaviours.” Given that 50 miles represents a significant increase of about 15%, these numbers may reflect Tesla’s characteristic “optimism.” Since these estimates are based on internal models rather than EPA-cycle testing, actual results may vary.
Currently, the upgrade is available only in the US. Tesla has a history of offering vehicles at one price and later providing software upgrades to enhance them. Opinions on this practice are mixed. While it’s common for automakers to limit certain features to higher trim levels, the idea of paying extra to unlock existing capabilities can feel frustrating to consumers.
Furthermore, the type of battery cells used and the potential impact of unlocking additional capacity on battery longevity raise additional questions. Tesla has previously differentiated products based on battery capabilities, as seen with the “A” and “B” battery packs on early Model S vehicles. Concerns also arise about whether Tesla could reduce a car’s capabilities through software updates, an issue that has occurred before.
Dave, a Tesla owner of four years said: “Their range estimates are roughly 15-20% optimistic. If they say 300 miles, owners will realistically get 250 miles in real-world driving.”
The need for this extra range is also debatable. The Model Y already offers substantial range and access to Tesla’s Supercharger network. The additional range won’t speed up charging on road trips, protect the battery from degradation, or necessarily fit the daily driving needs of most owners. It might benefit those relying heavily on public chargers, but for many, the upgrade merely increases the numbers without adding practical value.
