Exploring the Real-World Range of the BYD Sealion 7
The rise of electric vehicles has brought with it a common concern for potential buyers: range anxiety. While battery technology continues to improve, the question of how far an EV can travel on a single charge remains crucial. The BYD Sealion 7, recently launched in the Indian market, aims to address these concerns. But how does its performance measure up in the real world?

The BYD Sealion 7 comes in two primary variants: Premium and Performance.
Both versions are equipped with an 82.6 kWh battery pack. The Premium variant features rear-wheel drive (RWD) and a manufacturer-claimed range of 567 km on a single charge. The Performance variant, offers all-wheel drive (AWD), but has a slightly reduced claimed range of 542 km.
One of the biggest challenges for EVs can be the difference between the manufacturer’s stated range and what drivers experience in real-world conditions. These discrepancies often arise because testing is done in controlled environments that don’t account for real-world factors such as traffic congestion, road conditions, and aggressive driving habits. However, improvements in battery efficiency and energy management are helping to close this gap.
BYD has a solid reputation for battery technology. The Sealion 7 has the potential to deliver a range closer to its official figures. But, what can we expect in actual driving conditions?
Real-World Range Testing
To assess the real-world range of the BYD Sealion 7, a test drive was conducted in Jaipur. The test vehicle, the Performance variant, has an 82.56 kWh battery pack with an all-wheel-drive (AWD) system. This variant delivers 523 bhp and 690 Nm of torque.
The extensive test drive, spanning approximately seven hours, covered a mix of congested city roads during peak times and sections of the recently constructed Delhi-Jaipur highway. The journey began with a fully charged battery, displaying a range of 542 km.
For the majority of the drive, the Sport mode, which prioritizes performance, was engaged. After covering 80 km, the battery level had dropped to 82%, with a remaining range of 450 km. This signifies that the Sealion 7 used 18% of its battery capacity to travel 80 km.
Considering these figures, the energy consumption rate was calculated at 0.1858 kWh/km. Based on this, the real-world range under the conditions of the test would be around 444 km, which is notably less than the manufacturer’s claim.
Keep in mind that extended periods of idling with the lights, air conditioning, and ventilated seats active, along with repeated performance tests such as acceleration and braking, as well as limited regenerative braking, all contributed to increased battery usage.
It is important to mention that, in ideal circumstances, the BYD Sealion 7 is easily capable of traveling between 450 and 480 kilometers on a single charge. This translates to roughly 85.7% of the claimed range, which remains a strong performance compared to other EVs currently available on the market.
