About Range and Efficiency

Your instrument panel shows "Rated Range", which is based on standardized EPA testing. However, real-world conditions differ. Elvee helps bridge this gap.

Rated vs. Real-world Range

• Rated Range: The EPA estimate. It assumes constant speeds on flat terrain.
• Real-world Range: Calculates how far you can actually drive based on your current efficiency trends (Wh/mi).

Key Efficiency Factors

1. Speed: Driving over 70 mph increases wind resistance exponentially.
2. Temperature: Cold weather increases cabin heating needs and reduces battery chemistry efficiency.
3. Elevation: Climbing steep hills increases energy consumption, though regenerative braking recovers some during the descent.
4. Wind: Direct headwinds can significantly lower efficiency.

In Elvee, you can view your Efficiency Breakdown in real time to understand exactly where your energy is going.
