Summary
- Out Of Spec conducted a highway range test between the new Tesla Model Y "Juniper" and the outgoing model, driving both until they ran out of power
- The new Model Y had a longer range on the EPA cycle and also performed better in real-world testing, but the old model was slightly more efficient
- The updated Model Y Long Range AWD achieved 298 miles of range at 70 mph, surpassing the 2024 Model Y Long Range AWD which went 285 miles
- Both models averaged around 3.7 miles per kWh, with the old model appearing to be slightly more efficient
- The efficiency differences are likely due to aero and tire advantages, as both models are noted as being among the most efficient electric crossovers tested and are still considered to be good vehicles.

The Importance of the Tesla Model Y
The Tesla Model Y is not just the best-selling car in the world regardless of powertrain type, but it is also the most efficient mainstream electric crossover and a crucial product for America’s biggest EV maker. With the introduction of the "Juniper" update, the Model Y has undergone significant improvements in terms of styling, interior upgrades, and enhanced ride quality. However, the focus remains on the claimed 10% increase in efficiency, prompting Out Of Spec to conduct a range test pitting the new Model Y against the old model.
The Range Test Results
During the range test conducted by Out Of Spec, both the new Model Y and the outgoing model were driven until they stopped. The updated Model Y Long Range AWD achieved an impressive 298 miles of range on a 70-mph highway test, surpassing the 2024 Model Y Long Range AWD which managed 285 miles. While the new model outperformed its predecessor in terms of overall range, the old Model Y appeared to be slightly more efficient, although the difference was negligible.
Efficiency Comparison
Both the new and old Model Y showcased impressive efficiency levels, averaging around 3.7 miles per kWh. Despite the new Model Y offering more usable capacity before coming to a complete stop, it did not demonstrate the anticipated 10% efficiency improvement. Factors such as aero and tire advantages, as well as heavy crosswinds, may have influenced the results. Out Of Spec acknowledges that both vehicles are among the most efficient electric crossovers they have tested, highlighting the advancements made by Tesla in terms of efficiency.
Challenges Faced
During the range test, Out Of Spec encountered challenges such as strong crosswinds, which could have impacted the results of the efficiency comparison. The real-world testing environment, with its inherent imperfections, may have resulted in minor discrepancies between the two Model Y variants. Despite these challenges, the overall efficiency and performance of both vehicles were commendable, showcasing Tesla’s commitment to producing top-tier electric cars.
Investigating the Efficiency Claims
The discrepancy between the claimed 10% efficiency improvement and the actual test results raises questions about the accuracy of Tesla’s assertions. While the new Model Y did demonstrate improved range and overall performance, the marginal difference in efficiency between the two models suggests that further investigation may be necessary. Out Of Spec’s thorough testing process provides valuable insights into the true efficiency levels of the Tesla Model Y, helping consumers make informed decisions about their EV purchases.
Conclusion
The Tesla Model Y remains a benchmark for electric crossovers, with both the new and old models showcasing impressive efficiency and performance capabilities. While the Juniper update introduces notable enhancements to the Model Y, including increased range and improved ride quality, the actual efficiency gains may not align with Tesla’s claims. Out Of Spec’s rigorous testing process sheds light on the true efficiency levels of the Model Y, offering valuable data for prospective buyers. Despite the challenges faced during the test, both Model Y variants proved to be among the most efficient electric crossovers on the market, reaffirming Tesla’s position as a leader in the EV industry.
