Every other car on this site uses a nickel-based cathode. The Seal uses lithium iron phosphate, and the differences run through the whole ownership experience rather than showing up in one row.
The Seal is one of only four cars in our database with a genuinely LFP pack — see electric cars with LFP batteries — and one of six on our 800V EV cars list for charging speed.
What LFP buys you
LFP cells begin thermal runaway at a substantially higher temperature than nickel-rich cells, and release less energy when they do. They also tolerate being held at a full state of charge, which nickel chemistries do not — with an NMC car the standard advice is to charge to eighty percent for daily use, while BYD actively recommends taking the Seal to one hundred percent regularly to keep the battery management system calibrated. Over years of ownership that is one less thing to manage.
What it costs you
150 kW peak and thirty-six minutes from 10 to 80 percent is the fifth-slowest of the 29 cars here with a sourced time, behind the F-150 Lightning, R1S, Ariya and Equinox EV, and more than double the Ioniq 6. LFP has lower energy density, so the pack is heavier for its capacity, and at 2,260 kg the Seal is heavy for a saloon. Cold weather also hits LFP harder than nickel chemistries, which matters in northern Europe.
The 3.8-second 0-100 time is genuinely quick, and at €53,990 the Seal undercuts the BMW i4 by several thousand euros while offering a similar amount of car. It is not sold in the United States.

Frequently asked questions
How far does the BYD Seal AWD Excellence really go on a charge?
The BYD Seal AWD Excellence covers about 445 km in independently observed mixed driving, 520 km on the WLTP cycle. That observed figure is about 86 per cent of the WLTP claim — a shortfall is normal for every electric car, and what matters is that this one is predictable rather than that it exists. We rank the size of that gap across the database on claimed vs real range.
How long does the BYD Seal AWD Excellence take to charge?
From 10 to 80 per cent on a DC rapid charger it takes about 36 minutes, peaking at 150 kW. That is at the slower end of the 18 cars we hold charging data for — worth weighing if you drive long distances often. On AC at home it accepts up to 11 kW. The peak figure on its own tells you very little — this ranking explains why the window is the honest measure.
How long will the BYD Seal AWD Excellence’s battery last?
Our projection puts it at roughly 84 per cent of original capacity after eight years. That is an estimate, not a measurement: nobody publishes per-model degradation data, so it applies the published rate for this vehicle class and is labelled as an estimate everywhere it appears. The reasoning is set out in full on the methodology page, and we compare warranty terms across the database on best EV battery warranties.
Who should buy the BYD Seal AWD Excellence?
On our data it is able to power household appliances from the pack at 3.3 kW. Against that, it is one of the thirstier cars here at 185 Wh/km and one of the slower cars to rapid charge at 36 minutes. Whether that suits you depends on how much of your charging happens at home and how often you drive beyond one charge — the running cost calculator takes your own mileage and tariff, and the comparison tool puts this car next to any other in the database.
