Tesla Suffers Major Range Reduction in Extreme Heat Test

This report investigates the performance of electric vehicles (EVs) in high-temperature conditions, focusing on a recent test conducted in Southern Spain. The study examines how extreme heat impacts the driving range and charging efficiency of several popular EV models, revealing substantial deviations from their manufacturer-claimed specifications.

Unveiling the True Impact of Intense Heat on Electric Vehicle Performance

The Critical Influence of Temperature on EV Performance

Electric vehicles operate most effectively within a specific temperature range, typically between 68°F and 77°F (20°C and 25°C), as this is optimal for their lithium-ion battery packs. When temperatures deviate significantly from this ideal, the vehicle's range can be adversely affected. While the impact of cold weather on EV range has been well-documented, this test aims to shed light on how extreme heat, specifically temperatures exceeding 104°F (40°C), influences EV capabilities.

Testing Methodology and Featured Electric Vehicles

To assess the effects of extreme heat, a UK-based publication conducted a comprehensive test in Southern Spain, known for its high temperatures. Three distinct electric vehicle models were selected for evaluation: a Citroen e-C3 with a 44 kWh battery and a claimed WLTP range of 199 miles (320 km), a Kia EV3 equipped with an 81.4 kWh long-range battery and a WLTP range of 362 miles (582 km), and a Tesla Model 3 Long Range dual-motor with an 80 kWh battery and a maximum claimed range of 436 miles (702 km). Both the Kia and Tesla models benefit from liquid thermal management systems for their batteries, as well as heat pumps, designed to help regulate temperature.

Performance Outcomes in Elevated Temperatures

The test involved driving these vehicles at highway speeds, a condition that typically challenges EV efficiency. The combination of high speeds and extreme ambient temperatures had a pronounced negative effect on all three vehicles' ranges. Each car recorded a significant shortfall compared to its official range ratings, a phenomenon observed similarly in severe cold conditions. The Citroen e-C3, for instance, was projected to achieve only 142 miles before depletion, marking a 28.7% reduction from its advertised range and exhibiting the lowest efficiency at 2.7 miles/kWh.

Comparative Analysis of Range Reduction

The Kia EV3, which concluded its test run with approximately 10% battery remaining, was estimated to have a total achievable range of 246 miles. This represents a 32% decrease from its official claim, with an average efficiency of 2.9 miles/kWh. However, the Tesla Model 3 Long Range experienced the most substantial reduction, falling approximately 44% short of its official range claim, with an estimated maximum of 244 miles. Despite having the best efficiency among the group at 3 miles/kWh, its range was significantly impacted, performing worse than the Kia EV3 in terms of actual distance covered.

Charging Dynamics in Extreme Heat

An unexpected finding from the test concerned the charging performance of the vehicles in the intense heat. Both the Kia and Tesla demonstrated impressive resilience, charging relatively quickly and closely aligning with their official fast-charging times for a 10% to 80% charge. The Tesla Model 3, for example, charged from 9% to 80% in 32 minutes, nearly matching its 27-minute claim. The Kia EV3 completed a 10% to 80% charge in 31 minutes, just 3 minutes beyond its specified time. In contrast, the Citroen e-C3, with its more basic battery thermal management system, charged at a maximum of 38 kW on a 50 kWh charger (due to a non-functional higher-powered alternative), requiring 74 minutes to reach 80% from a 3% starting point.

Factors Contributing to Tesla's Range Loss

The journalists conducting the test highlighted a particular factor contributing to the Tesla's greater range reduction: its full-length glass roof, even with a cover. This design necessitated a higher setting for the air conditioning to maintain a comfortable cabin temperature, thereby consuming more energy and significantly impacting the overall range more than in the other two vehicles. This underscores the intricate relationship between vehicle design, passenger comfort, and energy consumption in challenging environmental conditions.

Xpeng's Ambition: Surpassing Tesla in Europe and Beyond

Chinese automotive manufacturers are cementing their presence in the global market, with Xpeng emerging as a significant contender. At the recent IAA Munich, Europe's premier auto show, numerous Chinese brands demonstrated their advancements. While BYD and MG have seen considerable success with budget-friendly models, Xpeng is poised to make an even greater impact globally, directly challenging established players like Tesla.

Xpeng, an electric vehicle startup founded in the mid-2010s, initially launched with the G3 subcompact SUV. The company swiftly expanded its portfolio to include the P7 sedan and G9 SUV, designed to rival Tesla's Model S and X. Xpeng has since diversified its offerings, introducing the X9 minivan, G6 and G7 crossovers, and the Mona liftback sedan. A key differentiator for Xpeng is its emphasis on advanced driver-assistance technology, which has even attracted partnerships with automotive giants like the Volkswagen Group for its software and electrical architecture in China. Beyond vehicles, Xpeng is exploring futuristic concepts, including a flying car and humanoid robots, signaling a broad vision that extends far beyond conventional car manufacturing.

Xpeng's strategic focus on models like the G6 SUV and the Mona liftback sedan is particularly critical for its European expansion. Unlike some competitors that prioritize luxury, Xpeng offers competitively priced vehicles with enhanced features and a comfortable driving experience. The G6, for instance, is positioned as a strong alternative to the Tesla Model Y, boasting superior equipment and ride quality at a slightly lower price point in many European markets. This value proposition has already led to a significant increase in Xpeng's European sales. The Mona sedan, a compact vehicle with a projected European price around $30,000, offers an economical yet capable option, potentially appealing to a wider audience in search of affordable and practical electric transportation, directly competing with popular models like the Toyota Corolla. Xpeng's CEO, He Xiaopeng, has confirmed plans to bring Mona products, including a potential crossover variant, to Europe, further solidifying the company's commitment to this key market.

Tesla Discontinues Cheapest Cybertruck Variant Due to Low Demand

Tesla has ceased the production and sale of its most economical Cybertruck variant, the rear-wheel-drive (RWD) model, merely months following its initial release. This strategic shift underscores significant challenges in market acceptance for the futuristic electric truck, which has struggled to meet ambitious sales targets. Despite earlier projections of substantial production volumes, the Cybertruck's sales performance has fallen considerably short, leading to the rapid removal of the lower-priced option from the company's lineup.

The initial launch of the Cybertruck was met with high anticipation, with Tesla reporting over a million reservations and CEO Elon Musk envisioning production capacities ranging from 250,000 to potentially 500,000 units annually. However, current sales figures hover around a mere 20,000 units per year. This discrepancy is largely attributed to the vehicle's market entry at a higher price point and with fewer features than originally advertised, diluting its appeal to potential buyers.

In an effort to stimulate demand, Tesla introduced the more accessible Cybertruck RWD in April 2025, offering it at a starting price of $70,000, a $10,000 reduction from the all-wheel-drive (AWD) model. This version, however, was significantly stripped down, lacking crucial elements such as active air suspension, a motorized tonneau cover, and even essential power outlets in the bed, in addition to having only one motor. These omissions rendered the RWD model less appealing, failing to compensate for its lower price.

Consequently, the RWD Cybertruck was pulled from the market less than five months after its debut. Tesla updated its online configurator to reflect this change, removing the option for customers to purchase the RWD variant without introducing a replacement. This abrupt discontinuation suggests a lack of consumer interest in a compromised version of the vehicle, even at a reduced cost.

Industry analysts and potential customers alike found the RWD variant to be a poor value proposition. The removal of features deemed essential by many buyers for a modest price reduction did not resonate with the target audience. The core demographic for the Cybertruck, already considered niche, showed little enthusiasm for a model that sacrificed functionality for a slightly lower cost.

Looking ahead, the future trajectory for the Cybertruck remains uncertain. With sales significantly below projections, Tesla faces the challenge of re-evaluating its strategy. There is speculation that the company might consider upgrading the vehicle in the coming year, aligning it more closely with the original promises to potentially revitalize demand and broaden its appeal within the electric truck market.

This move highlights the complexities of launching innovative vehicles in a competitive market, particularly when initial specifications and pricing diverge significantly from the final product. The rapid withdrawal of the Cybertruck RWD model serves as a stark reminder of the importance of aligning product features and pricing with consumer expectations to ensure market success and sustained interest.
