A Critical Moment for the Nissan Leaf
The 2026 Nissan Leaf arrives at a crucial time for affordable electric vehicles in the U.S. market. Positioned as a practical, well-equipped EV with competitive pricing, the new Leaf has become one of Nissan’s most important electric models in years. Its balance of range, features, and cost earned it recognition as a standout EV in 2025, but one key question remained unanswered: how does it perform on the highway at sustained speeds?
As deliveries begin nationwide, independent testers are finally providing real-world data that goes beyond laboratory estimates. A recent 70 mph highway range test offers valuable insight for buyers who regularly drive long distances.
EPA Ratings and What They Really Mean
The tested vehicle was the 2026 Nissan Leaf Platinum+, the highest trim level in the lineup. With a starting price of $40,485, it is EPA-rated for 259 miles of range. While respectable, this figure is lower than other Leaf trims due to its 19-inch wheels and higher energy consumption.
According to official figures, the Platinum+ averages 33 kWh per 100 miles, or 3.03 miles per kWh, making it the least efficient version of the Leaf. Importantly, EPA ratings are based on mixed driving cycles and do not reflect continuous highway driving, which is typically more demanding for EVs.
70 MPH Highway Test: Cold Weather Results
During the real-world test, the Leaf Platinum+ was driven at a constant 70 mph in winter conditions, with ambient temperatures averaging 38°F (3.3°C). Under these circumstances, the vehicle covered 215 miles before power output was limited.
This result represents a 17% reduction compared to the EPA estimate, a gap that is actually smaller than what many competing EVs experience under similar conditions. Cold air increases aerodynamic drag, and EV batteries are less efficient at low temperatures, making range losses unavoidable.
Efficiency and Battery Performance Insights
Despite the cold weather, the Leaf demonstrated solid energy efficiency, averaging 2.8 miles per kWh—only 7.6% below its official rating. This suggests that Nissan’s efficiency estimates are relatively conservative.
Notably, the test also indicated approximately 76 kWh of usable energy, slightly exceeding Nissan’s stated 75 kWh usable battery capacity. This buffer may help explain the Leaf’s consistent real-world performance compared to expectations.
It’s also worth noting that very few EVs match or exceed their EPA range at steady highway speeds. By contrast, in mixed-route testing designed to mirror typical American driving patterns, the same Leaf trim reportedly achieved over 300 miles on a single charge.
Price, Value, and Market Competition
At just over $40,000, the Platinum+ faces stiff competition. The Tesla Model Y, which offers more space and longer range, starts at a similar price point. However, that base Model Y includes fewer features than the fully loaded Leaf Platinum+.
The more compelling value may lie in lower Leaf trims, all of which use the same 75 kWh battery. The SV+, starting at $35,725, is rated for 288 miles, while the entry-level S+, priced at $31,485, offers an estimated 303 miles of range. For many buyers, these versions deliver a stronger balance of cost and efficiency.
What This Test Means for EV Buyers
The 70 mph highway test confirms that the 2026 Nissan Leaf delivers predictable, competitive real-world range, even in cold conditions. While it doesn’t outperform its EPA rating, it holds up better than many rivals and remains a practical option for daily driving and longer trips.
For buyers prioritizing affordability, transparency, and consistent performance, the Leaf—especially in lower trims—continues to be a strong contender in the evolving EV market.
