Tesla Semi Proves Its Power

Data from GEOTAB and NACFE highlights Tesla Semi's capabilities. The event pushed Tesla's Class-8 truck to its limits, testing maximum payload and long-distance travel. -Dave Mullaney from Rocky Mountain Institute shares key findings from Day 1.

Tesla Semi 1: The Powerhouse

• Covered 335 miles on a single charge in 8 hours.
• Ended with 17.5% battery left for a buffer.
• Mostly highway driving at 62 mph.

Tesla Semi 2: Impressive Efficiency

• Traveled 227 miles in about 6 hours.
• Ended with 27% battery remaining.
• Spent half the time idle, but maintained highway speeds.

Tesla Semi 3: Pushing the Limits

• Achieved 377 miles with battery bottoming out at 1.6%.
• Predominantly highway driving at 62 mph.

What We've Learned

• Tesla's range estimates seem accurate.
• Many unknowns remain, such as load weight and weather conditions.
• Opportunity charging may be necessary for ranges beyond 350 miles.

Dave Mullaney on Tesla Semi: "The 350-mile truck is for real, but unknowns remain. Opportunity charging will be crucial for extended ranges."

A Tesla Semi has traveled 729 miles in a single day as part of the Run for Less study. Look at that beautiful use case: it did two deliveries during that time and charged a bit while loading/unloading.
