Frequently asked questions
Is the BMW i4 worth the extra £7,145 over the Audi Q4 e-tron?
The BMW i4 costs £7,145 more than the Audi Q4 e-tron. For that premium it adds 93 miles more WLTP range, 40 kW faster peak rapid charging and 100 kW more power. The Audi Q4 e-tron is not just cheaper - it also offers 50 litres more boot space. On EVcarsguide's combined category scores, the Audi Q4 e-tron comes out ahead overall.
Which is cheaper to own over 5 years, the Audi Q4 e-tron or the BMW i4?
The Audi Q4 e-tron is £7,145 cheaper to buy. Running costs are almost identical - about £160 a year either way, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the Audi Q4 e-tron comes out roughly £7,225 cheaper overall. These figures cover list price and home charging only - insurance, servicing, tyres and depreciation will move the real total.
What are the Audi Q4 e-tron and BMW i4 like on a long motorway trip?
EVcarsguide estimates a real-world motorway range of about 229 miles for the Audi Q4 e-tron and 261 miles for the BMW i4 - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The BMW i4 goes roughly 32 miles further between charging stops.
Which is easier to park and drive in town, the Audi Q4 e-tron or the BMW i4?
The two are within 13 mm on width, so neither is meaningfully easier to thread into a tight space. In a standard 2,400 mm bay that leaves about 548 mm of total clearance for the BMW i4 and about 535 mm of total clearance for the Audi Q4 e-tron. The Audi Q4 e-tron also turns in a 2.3 m tighter circle, which helps with U-turns and multi-storey ramps.
Which battery will hold up better as a used buy, the Audi Q4 e-tron or the BMW i4?
Over a 8-year ownership window EVcarsguide's degradation model projects roughly 84% battery health for the Audi Q4 e-tron and 84% for the BMW i4. That is close enough that capacity loss should not decide between them. Both use NMC-type cells, so for daily use keep the charge limit near 80% to slow degradation. Both batteries carry a 8-year manufacturer warranty.
