Would you drive slower on the highway to significantly increase your electric vehicle's driving range?
Recent testing of the 2027 Chevrolet Bolt demonstrated significant variance in driving range based on constant speed. The vehicle, equipped with a 65 kWh battery, achieved a maximum of 280.3 miles at 60 mph.
Why it matters
Understanding how speed impacts electric vehicle battery efficiency is essential for drivers planning long trips. The results highlight the divergence between EPA estimates and real-world performance at higher highway speeds.
The 2027 Chevrolet Bolt features a 65 kWh lithium iron phosphate battery and achieved an efficiency of 4.1 miles-per-kWh at 60 mph. These results compare to an official EPA highway range rating of 232 miles.

Roadmap
This real-world test provides a practical counterpoint to the EPA's Multi-Cycle Test Procedure used to certify vehicle range. It underscores the ongoing industry challenge of reconciling standardized lab efficiency with the realities of high-speed highway travel.
Drivers of the 2027 Chevrolet Bolt should anticipate shorter ranges when maintaining highway speeds above 70 mph compared to the EPA's highway rating of 232 miles. Planning trips with these efficiency metrics can help owners better estimate charging stops.
The takeaway
Real-world driving conditions, particularly higher speeds, significantly reduce the range of electric vehicles compared to official ratings. Motorists should prioritize consistent, moderate speeds to maximize their vehicle's efficiency during long-distance travel.
