A recent real-world range test conducted by What Car? has provided valuable insights into the distance drivers can expect to cover on some of the latest electric vehicles (EVs).
The test revealed that the Tesla Model 3 RWD was the most efficient, averaging 4.4 miles per kWh, while the Audi Q6 e-tron Launch Edition was the least efficient, managing only 3 miles per kWh. This translates to a significant difference in costs, with the Model 3 costing roughly £508 on electricity every 10,000 miles compared to £745 for the Q6 e-tron if charged at home.
However, if charging at a public rapid charger where prices are higher at 79p per kWh, the Model 3 would cost £1,795 for 10,000 miles, while the Q6 e-tron would cost £2,633. This highlights the potential extra cost of £838 by choosing one EV over another.
Steve Huntingford, editor of What Car?, emphasized the importance of efficiency as energy prices continue to rise. He noted that while electric cars used to be significantly cheaper to run, efficiency now plays a crucial role in cost considerations.
The test also showcased the advancements in battery technology, with the Polestar 2 Long Range Single Motor surpassing all other electric cars in terms of range. The Polestar 2 achieved an impressive 333 miles on a single charge, demonstrating the progress in battery capabilities.
Additionally, the test included a nine-year-old Tesla Model S with 258,000 miles on the clock to assess battery longevity concerns. Despite its age and mileage, the Model S only lost 8% of its original capacity, indicating the durability of EV batteries over time.
Geotab’s analysis of nearly 5,000 fleet and private EVs further supported the test findings, showing an average battery degradation rate of 1.8% per year, an improvement from 2.3% in 2019. This suggests that the latest battery technology is more resilient to daily use.
The test was conducted at the Horiba-MIRA proving ground in Warwickshire, where EVs were driven on a 19.2-mile test route featuring various driving conditions. The consistent driving parameters allowed for accurate comparisons between different models.
Overall, the range test results provide valuable information for consumers considering purchasing an electric vehicle, emphasizing the importance of efficiency, battery technology, and long-term durability in making an informed decision.
