Frequently asked questions
Which is cheaper to own over 5 years, the BYD Dolphin or the Jeep Avenger?
The Jeep Avenger is £196 cheaper to buy. Running costs are almost identical - about £152 a year either way, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the two land within £116 of each other - effectively the same to own. These figures cover list price and home charging only - insurance, servicing, tyres and depreciation will move the real total.
What are the BYD Dolphin and Jeep Avenger like on a long motorway trip?
EVcarsguide estimates a real-world motorway range of about 221 miles for the BYD Dolphin and 171 miles for the Jeep Avenger - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The BYD Dolphin goes roughly 49 miles further between charging stops.
Which is easier to park and drive in town, the BYD Dolphin or the Jeep Avenger?
The BYD Dolphin is the easier car for tight UK car parks: it is 40 mm narrower than the Jeep Avenger. In a standard 2,400 mm bay that leaves about 630 mm of total clearance for the BYD Dolphin and about 590 mm of total clearance for the Jeep Avenger. The BYD Dolphin also turns in a 1.1 m tighter circle, which helps with U-turns and multi-storey ramps.
Which battery will hold up better as a used buy, the BYD Dolphin or the Jeep Avenger?
Over a 8-year ownership window EVcarsguide's degradation model projects roughly 90% battery health for the BYD Dolphin and 84% for the Jeep Avenger. That gives the BYD Dolphin a modest edge in retained real-world range. The BYD Dolphin's LFP-type pack tolerates daily 100% charging, while the Jeep Avenger's NMC-type pack lasts longest kept to about 80% for everyday use. Both batteries carry a 8-year manufacturer warranty.
