Frequently asked questions
Is the BYD Sealion 7 worth the extra £4,640 over the Ford Mustang Mach-E?
The BYD Sealion 7 costs £4,640 more than the Ford Mustang Mach-E. For that premium it adds 27 miles more WLTP range, 35 kW faster peak rapid charging and 118 litres more boot space. The Ford Mustang Mach-E is not just cheaper - it also offers lower energy use, 179 versus 199 Wh/km. On EVcarsguide's combined category scores, the BYD Sealion 7 comes out ahead overall.
Which is cheaper to own over 5 years, the BYD Sealion 7 or the Ford Mustang Mach-E?
The Ford Mustang Mach-E is £4,640 cheaper to buy. Running costs are almost identical - about £192 a year either way, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the Ford Mustang Mach-E comes out roughly £4,760 cheaper overall. These figures cover list price and home charging only - insurance, servicing, tyres and depreciation will move the real total.
What are the BYD Sealion 7 and Ford Mustang Mach-E like on a long motorway trip?
EVcarsguide estimates a real-world motorway range of about 204 miles for the BYD Sealion 7 and 203 miles for the Ford Mustang Mach-E - effectively matched, and both well below their WLTP figures because sustained high speed is the hardest case for an EV. A rapid charge to 80% takes around 24 minutes in the BYD Sealion 7 and 32 in the Ford Mustang Mach-E, so the BYD Sealion 7 loses less time at each stop.
Which is easier to park and drive in town, the BYD Sealion 7 or the Ford Mustang Mach-E?
The two are within 5 mm on width, so neither is meaningfully easier to thread into a tight space. In a standard 2,400 mm bay that leaves about 475 mm of total clearance for the BYD Sealion 7 and about 470 mm of total clearance for the Ford Mustang Mach-E.
Which battery will hold up better as a used buy, the BYD Sealion 7 or the Ford Mustang Mach-E?
Over a 8-year ownership window EVcarsguide's degradation model projects roughly 90% battery health for the BYD Sealion 7 and 90% for the Ford Mustang Mach-E. That is close enough that capacity loss should not decide between them. Both use LFP-type cells, which are happy charged to 100% every day. Both batteries carry a 8-year manufacturer warranty.
