Overview

• Tesla Model 3 covered 244 miles versus a 436-mile claim, a 44% drop, the largest shortfall in the test.
• Kia EV3 reached 246 miles against a 362-mile claim (down 32%), while the Citroën e‑C3 managed 142 miles versus 199 miles (down 29%).
• Drivers set off between Seville and Córdoba after charging to 90–100% for a roughly 400 km route in temperatures ranging from 32C to 44C.
• Across the three cars, the average gap from official figures was 35%, which What Car? says is worse than its latest winter test and more than double its 2024 summer discrepancy.
• What Car? published usable battery sizes, test ranges and efficiency figures, and noted the findings underscore the need for better heat management as hot weather becomes more frequent.
