Would you drive slower on the highway to significantly increase your electric vehicle's driving range?
The 2027 Chevrolet Bolt, equipped with a 65 kWh lithium iron phosphate battery, achieved a range of 280.3 miles at 60 mph in a recent road test. This performance helps prospective owners understand how the electric vehicle handles varying highway speeds.
Why it matters
Understanding how speed affects battery efficiency is essential for planning long-distance travel and managing charging logistics. Higher speeds significantly reduce the total distance an electric vehicle can travel before needing a charge.
The vehicle demonstrated an efficiency of 4.1 miles-per-kWh at 60 mph, compared to 3.2 miles/kWh at 80 mph. These results differ from the EPA combined range estimate of 262 miles.
The players
Chevrolet
A major automotive brand known for its long-standing history in consumer vehicles and its current commitment to the expansion of its electric vehicle fleet.
Tom Moloughney
A recognized electric vehicle expert and test driver who performed the real-world range evaluation.
The details
The test on the New Jersey Turnpike utilized the vehicle's 65 kWh battery and Super Cruise technology to maintain constant speeds. As driving speed increased from 60 mph to 80 mph, the vehicle saw a measurable drop in efficiency and total range. This decline highlights the impact of aerodynamic drag at higher velocity on lithium iron phosphate battery systems.

The Home Front
The study provides a reality check on the standardized EPA range ratings used to market electric vehicles to suburban homeowners. These results follow a trend of independent testing meant to clarify how high-speed driving affects real-world travel capability.
Review your planned commute speeds when estimating your vehicle's weekly charging frequency requirements. Consider that maintaining a 60 mph speed can significantly extend your range compared to driving at 80 mph on open highways.
The takeaway
Driving at higher speeds creates a predictable drop in energy efficiency that may require more frequent charging stops. Use these range figures to refine your travel plans, and remember to monitor your vehicle's real-time efficiency display during long trips.
