Adding a third row and extra length typically reduces an EV’s range, but the new Tesla Model Y L is bucking that trend. According to Edmunds’ standardized EV Range Test, the extended-wheelbase Model Y L AWD delivered a real-world result that surpasses Tesla’s own estimates.
Model Y L Delivers Surprising Efficiency
The 2027 Tesla Model Y L AWD, an extended-wheelbase, three-row, six-seat version of the Model Y, was officially launched in the U.S. last month. Edmunds tested the Model Y L AWD and recorded 358 miles (~576 km) of range on a single charge, exceeding Tesla’s internal estimate of 320 miles (~515 km) by 11.8%.
Despite weighing 300 lb (~136 kg) more than the Premium AWD trim, the Model Y L outperformed every other Model Y variant currently available. This makes it the longest-range Model Y Edmunds has tested to date.
How Tesla Achieved the Extra Range
Tesla credits several engineering improvements for the Model Y L’s efficiency. The vehicle features a drag coefficient of just 0.216, thanks to new enclosed 20-inch Uberhelix wheels and an integrated rear spoiler. According to Tesla, molding the spoiler directly into the rear hatch, rather than bolting it on, added 15 miles (~24 km) of driving range and improved rear passenger headroom by raising the third-row brake light.
The Model Y L also benefits from a more powerful rear motor, borrowed from the Model Y Performance, and a larger battery pack with a capacity of roughly 83 kWh. Enhanced thermal management, including triple-layer silver coatings on the glass roof that reject 30% more solar heat, helps reduce energy consumption by making the HVAC system more efficient. The Model Y L introduces three temperature zones for climate control, a first for Tesla.
Real-World Range Compared to Other Model Y Variants
Edmunds’ testing showed the following results for the current Model Y lineup:
• Model Y L AWD: 358 miles (~576 km) tested vs. 320 miles (~515 km) estimated (25.1 kWh/100 mi) • Model Y RWD: 337 miles (~542 km) tested vs. 321 miles (~517 km) estimated (22.8 kWh/100 mi) • Model Y Premium AWD: 327 miles (~526 km) tested vs. 327 miles (~526 km) estimated (26.8 kWh/100 mi) • Model Y Performance: 293 miles (~472 km) tested vs. 306 miles (~492 km) estimated (30.8 kWh/100 mi)
The Model Y L’s ability to deliver more range than expected, despite its added weight and third-row seating, highlights Tesla’s focus on aerodynamic and thermal efficiency rather than simply increasing battery size.
Competitor Comparison
The Tesla Model Y L faces competition from other three-row electric SUVs, including the Hyundai Ioniq 9, Kia EV9, and Rivian R1S. The Hyundai Ioniq 9 and Kia EV9 both offer more interior space, while the Rivian R1S is positioned as a premium option with greater room and larger battery packs. However, these rivals typically rely on bigger batteries to achieve similar or slightly longer ranges, resulting in higher energy consumption per mile compared to the Model Y L’s efficiency-focused approach.
Regional Availability
Tesla launched the Model Y L in the U.S. last month, with customer deliveries scheduled to begin in September. Display vehicles are already arriving at showrooms across the country, allowing potential buyers to experience the new variant firsthand.
Why this matters
The Model Y L’s real-world range performance demonstrates that smart engineering can offset the typical efficiency losses associated with larger, heavier EVs. By focusing on aerodynamics, thermal management, and powertrain improvements, Tesla has delivered a three-row SUV that competes on range without resorting to oversized battery packs.
This approach could influence future EV designs, encouraging automakers to prioritize efficiency gains over simply increasing battery capacity.
What this means for buyers
For buyers considering a three-row electric SUV, the Model Y L offers a compelling blend of range, efficiency, and practicality. With deliveries starting in September and display models already in showrooms, shoppers can compare the Model Y L directly with competitors like the Hyundai Ioniq 9, Kia EV9, and Rivian R1S. Those prioritizing real-world efficiency and advanced climate features may find the Model Y L particularly attractive.
