Electric Car Winter Ranges DISCOVERED

How cold weather affects electric vehicles?

In the pursuit of understanding the practical winter ranges of electric cars, a recent comprehensive range test was conducted on a diverse set of 10 electric vehicles (EVs). This detailed exploration aims to uncover individual performance metrics, efficiency measures, and key highlights, providing consumers with a comprehensive overview of these electric vehicles' capabilities in cold weather conditions.

Testing Methodology

The range tests were conducted biannually, encompassing both summer and winter evaluations to capture the varying performances of electric cars under different temperatures. All 10 electric cars underwent identical testing conditions on a private Proving Ground, navigating a 15-mile route that included stop-start urban driving, steady speeds at 50 miles per hour, and constant speeds at 70 miles per hour.

Temperature Normalization

Recognizing the substantial impact of temperature on electric car efficiency, a crucial step involved standardizing interior conditions. The chosen temperature was 19.5 degrees Celsius, ensuring a fair baseline for evaluating each car's winter range performance.

Efficiency Metrics

Efficiency measures played a pivotal role in assessing how effectively electric cars utilized stored electricity. The chosen metric was miles per kilowatt-hour (miles/kWh), offering insights into the energy efficiency of each vehicle.

Individual Results and Highlights:

1. Mini Electric: Achieved the least winter range at 113 miles but stood out as the most energy-efficient, averaging an impressive 3.9 miles/kWh.

2. Aura Funky Cat: Covered 130 miles, falling short of its official WLTP range, with an efficiency of 2.9 miles/kWh.

3. Cooper Born: Managed 182 miles, showcasing a 20% reduction in range compared to a summer test.

4. Volkswagen ID Buzz: Dropped out at 192 miles, exhibiting an average efficiency of 2.5 miles/kWh.

5. MG4 Long Range: Covered 196 miles, aligning closely with its official 270-mile range, and showcased an efficiency of 2.7 miles/kWh.

6. Jaguar I-Pace: Stopped at 197 miles, displaying an efficiency of 2.3 miles/kWh, making it the least efficient among the tested vehicles.

7. Genesis GV60: Completed 251 miles, showcasing commendable winter range performance.

8. BMW i4: Gave up at 261 miles, indicating the impact of winter conditions on its range.

9. Nissan Ariya: Showed resilience in limp mode, covering 269 miles and demonstrating competitive winter range capabilities.

10. Tesla Model Y: Impressed with an outstanding winter range of 272 miles, maintaining high efficiency at 3.6 miles/kWh.

The top performers included:

1. Nissan Ariya: Displaying resilience in limp mode, it covered 269 miles, falling slightly short of its WLTP range.

2. Tesla Model Y: Impressed with an outstanding 272 miles, demonstrating high efficiency at 3.6 miles/kWh.


The comprehensive winter range test of 10 electric vehicles (EVs) provided valuable insights into their real-world performance under cold conditions. Here are the key conclusions drawn from the analysis:

  1. Temperature Impact on Efficiency: The winter test underscored the significant impact of colder temperatures on electric car efficiency. Each vehicle's ability to maintain optimal range was influenced by the challenging weather conditions, highlighting the importance of considering seasonal variations for prospective EV buyers.

  2. Individual Vehicle Performance: The test revealed distinct performances among the 10 EVs, showcasing their strengths and limitations in cold weather. While some vehicles demonstrated remarkable efficiency and resilience, others experienced notable reductions in range, emphasizing the need for consumers to choose models that align with their specific usage patterns and climate.

  3. Efficiency Metrics: The efficiency metrics, measured in miles per kilowatt-hour (miles/kWh), served as crucial indicators of how effectively each EV utilized its stored electricity. This information is vital for consumers seeking to maximize their driving range and minimize charging frequency, especially during winter months.

  4. Range Anxiety Considerations: The varying winter ranges of the EVs highlighted the existence of range anxiety, particularly for models with shorter ranges. Understanding the limitations in colder conditions can assist consumers in planning their journeys effectively and considering charging infrastructure availability.

  5. Resilience and Adaptability: Some EVs showcased impressive resilience in adverse weather conditions, surpassing expectations and delivering commendable winter ranges. This highlights the adaptability of certain models to challenging climates, providing consumers with confidence in their EV choices.

  6. Future Considerations: As the electric vehicle market continues to evolve, manufacturers may address the seasonal challenges revealed in this test through technological advancements, improved battery efficiency, and enhanced climate control systems. Continuous innovation is key to overcoming the obstacles associated with winter driving for electric cars.
