On a full battery and open highway, the Tesla Model Y Performance showed why it remains a reference point in the electric vehicle market. In a recent endurance test, it ran at a steady 113 km/h until the battery was depleted, recording real-world range ahead of its closest competitors.
Conducted by Out of Spec, the test saw the Model Y Performance cover approximately 499 kilometers before stopping. That figure slightly exceeds its official WLTP rating of 492 kilometers, a rare result for an electric vehicle in real-world conditions. The test was simple: charge the car to 100% and lead at a steady speed until the battery runs out. A controlled constant-speed run makes comparisons more useful, though tire choice and vehicle configuration, along with temperature, wind, road grade and battery state, can all affect the result.
The same test included the Rivian R2, a new electric SUV with a rugged design and a strong market presence. Despite its tough image and advanced features, the R2 managed only 407 kilometers under identical conditions. The gap shows how much aerodynamics and software improvement matter, areas where Tesla continues to invest heavily.
A separate Out of Spec highway run offers more context, but used a different setup: in cool weather, an R2 Performance on optional 20-inch all-terrain tires covered 212.3 miles, or about 342 kilometers, at a steady 70 mph, roughly 113 km/h. For that tire configuration, its window-sticker estimates were 307 miles combined and 276 miles on the EPA highway cycle; the 21-inch all-season configuration was rated at 330 miles combined. The test R2 averaged 2.45 miles per kWh, while Kyle Conner reported an approximate battery capacity of 88 kWh. These results do not directly certify the range figure above. They show how test conditions and wheel-and-tire choice shape highway performance.
In a separate efficiency comparison, Out of Spec found that the R2 Performance used more energy than a Tesla Model Y Performance at comparable speeds. The reported gap ranged from 18.4% at 50 mph to 26.5% at 80 mph. Both vehicles were listed at 105 MPGe and 32 kWh per 100 miles in the cited EPA comparison, but standardized ratings do not guarantee identical consumption during constant-speed highway driving. Conner put it bluntly: “everyone needs to stop saying that it’s matching the efficiency of Model Y.”
The Model Y Performance is not the most range-focused version in Tesla’s lineup, but its battery and power-management efficiency, alongside its aerodynamic design, deliver strong results. It accelerates from 0 to 100 km/h in 3.3 seconds and reaches a top speed of 250 km/h, while keeping energy consumption remarkably low at highway speeds.
The Model Y’s shape is one factor behind that efficiency. Its rounded profile has drawn criticism for its looks, but helps the car cut through the air, reducing drag and extending range. By contrast, SUVs with boxier or off-road-inspired designs often trade efficiency for style, bringing higher consumption and shorter real-world range.
For drivers planning long journeys, the difference matters. A car that travels farther between charges saves time and eases the worry of finding charging stations along the way. Tesla’s extensive Supercharger network strengthens its position, making the Model Y a practical choice for drivers who depend on an EV as their basic vehicle.
Many electric cars perform well in city driving, but highway efficiency is harder to maintain. As speed rises, aerodynamic resistance becomes a dominant factor, and only the most optimized vehicles hold onto strong range figures. The recent test shows how Tesla’s engineering focus pays off under these conditions.
Recent developments in US safety standards are also shaping the industry. For example, new federal rules on emergency exits are set to affect future models, even as Tesla avoids a formal investigation into its Model 3 door mechanisms.
As electric vehicles become more common on Spanish roads, real-world range and charging convenience are increasingly decisive for buyers. The latest Model Y Performance results suggest that Tesla’s technology and infrastructure continue to set the pace in the EV race.
