During our performance testing, the 2025 Porsche Taycan 4S sedan showed a 50% boost in range, increasing from 220 miles to 330 miles. The rear-drive model’s range increased from 280 miles to 360 miles, a 29% rise. Efficiency increased significantly in both types. The 4S increased by almost 30%, and the rear-driver by 11%. Cars performed very well in estimating range during our range test, with a variation of about 1% from start to finish. At Invoice-pricing’s Testing Hub, we focus on the test numbers. You can learn more about our car testing methods here. Since 1956, we’ve been pushing cars to their limits to gather objective data to support our emotional assessments. Technology has long been judged by how well it works and how effectively it improves over time. To be successful, a product must be significantly better than its predecessor. This is true whether it’s the Nintendo 64 being considered better than the GameCube or the iPhone 8 being considered better than the iPhone X. Elon Musk has stated that Tesla should be viewed as a technology company rather than a traditional automaker. Similarly, NVIDIA has been criticized lately for slow performance increases. Both companies have struggled to show significant improvements over the last few years. Porsche has a small share of the electric vehicle market, but its second-generation Taycan went significantly further, offering much better range and efficiency. We first tried the Taycan’s 4S and rear-wheel-drive models in 2021. At 75 mph, they performed well in our range test, achieving distances of 220 and 280 miles, which exceeded their EPA ratings by tens of miles. Today, however, these are in the middle of the pack based on our examination. We got 360 miles from the rear-wheel-drive car in the same test, and 330 miles from the 4S in the 2025 updated EV sedan. Based on these results, the range is expected to grow by 50% and by almost 29%, respectively. Additionally, their consumption increases by 29% (from 2.63 to 3.4 miles per kWh) and 11% (from 3.34 to 3.71 miles per kWh). But these numbers don’t always tell the whole story. The first area is under the floor. In 2025, Taycans will have larger cells—up to 97 kWh instead of 83.7 kWh when equipped with the Performance Battery Plus—but they will still be the same size. Because the chemicals were better mixed and there was more nickel, Porsche was able to significantly increase the NMC battery’s energy efficiency, allowing it to charge and discharge faster. The weight of the test vehicles stayed nearly unchanged, with the 4S gaining just 15 pounds and the rear-wheel-drive model adding 69 pounds. However, the benefits go far beyond a 16% rise in battery power. Porsche made numerous changes to the new Taycan’s aerodynamics, from sealing the headlights to optimizing the flatness of the tire sidewalls, to achieve a significantly longer range. Although the updated model bears a resemblance to the old one, these modifications have enhanced its performance. The wheel and tire packages of the cars being tried are another factor that can change. When we compared the two 4S cars side by side, the younger one had smaller Hankook Ion Evo summer tires on 21-inch wheels, designed to be more aerodynamic, while the older one had wider Pirelli P Zero summer tires on more standard 21-inch wheels. Both cars had 20-inch wheels, but the 2021 model had stiffer wheels and smaller tires. In contrast, the rear-wheel-drive model, due to its less efficient design, showed the opposite effect. Porsche claims that the racing wheels by themselves can add around 20 extra miles to the vehicle’s range. This would explain why these two versions are better in different ways. Additionally, the RWD Taycan may have a maximum range of approximately 400 miles, provided all requirements are met. Another standout feature of the updated Taycan is its improved accuracy in predicting driving range. At the beginning of our range test loop, the Taycan 4S had a range of 330 miles, which remained consistent throughout. With rear-wheel drive, it showed 356 miles instead of 360 miles, which was not as accurate but still very close. This is particularly important for alleviating range anxiety in real-life situations, especially for those new to EVs. This is a great place to start if Porsche wants to capture a larger market share with the new Taycan, as it is more fuel-efficient and offers a longer range.
