Range anxiety remains a major concern among potential buyers of electric vehicles. However, battery technology and management systems have been improved over the years, which helps the electric vehicles reach longer ranges and lessen this anxiety. The Chinese electric vehicle maker, BYD has always been one of the greatest in EV battery technology, and its newly launched BYD Sealion 7 in the Indian market goes in the same line.
The BYD Sealion 7 comes in two variants, both powered by an 82.6 kWh battery pack. The Premium variant gets rear-wheel-drive (RWD) with a claimed range of 567 km on a single charge, while the Performance variant gets all-wheel-drive (AWD) but claims slightly less range of 542 km.

One of the most significant problems of EVs is the disparity between claimed range values by manufacturers and actual driving ability. The discrepancy exists due to the fact that manufacturers normally calculate range estimates using tests conducted under controlled environments that often do not represent real-world traffic congestion, road gradations, or hard acceleration habits. Consequently, real-world range usually is below stated claims.
With continuous improvements in battery efficiency and energy management, manufacturers are working to close the gap between theoretical and real-world range. With BYD’s experience in battery technology, particularly in energy-efficient designs and sophisticated battery management systems, the Sealion 7 can potentially achieve a range much closer to its official numbers. But how realistic are BYD’s range claims for the Sealion 7 in real-world Indian conditions? Let’s see.

BYD Sealion 7: Real world range
We recentlygotachance todrive the BYD Sealion 7 in Jaipur. Our test car was the Performanceversion,whichgets an 82.56 kWh battery pack and an all-wheel-drive (AWD) system.This variant,according to BYD,can cover 542 km on a single chargeandmakes523 bhp and 690 Nm of torque.
Our test drive ofaround seven hoursincluded acombination ofcongested city roads in Jaipur at peaktimes andsections of the newly constructed Delhi-Jaipur highway. The drivebegan with acharged battery (100 per cent), showing a range of 542 km. Wemostly drove in Sport mode duringthe drive,which prioritises performance over efficiency.
At the end of the day, we had covered 80 km, and the battery level hadfallen to 82 per cent, with a displayed range of 450 km. This indicatesthatthe Sealion 7consumed 18 per cent of its battery to cover 80 km.

Bearingthisin mind, 18 per cent of the overall battery capacity (82.56 kWh) is 14.86 kWh,whichresultsin an energy consumption rate of 0.1858 kWh/km. Extrapolating thesefigures, thereal-world range of the BYD Sealion 7 under our test conditions would be around 444 km—which issignificantlyless than thestatedvalue.
While the tested range was still below BYD’s stated claim, extended idling with lights, AC, and ventilated seats on, repeated performance tests such as acceleration and braking tests, and limited regenerative braking coupled with hard driving all added to increased battery usage.
So, in ideal situations, the BYD Sealion 7 can easily travel anywhere between 450 kms to 480 kms. This turns out to be about 85.7 per cent of the claimed range, which is higher than most of the EVs in the market.
