What the numbers say
The Audi Q4 e-tron 45 costs about £54,611 to own over 5 years in the UK — £910/month, £0.91/mi at 12,000 mi/yr — and depreciation is the biggest line: £32,209, 59% of the total (as of August 6, 2026).
- The Audi Q3 TFSI 150 Sport wins decisively here — £13,658 cheaper over 5 years; at typical assumptions this isn't a close call.
- No realistic annual distance flips this verdict — the Audi Q3 TFSI 150 Sport stays the cheaper car at every distance we model.
- Where the Audi Q4 e-tron 45's £54,611 actually goes: depreciation £32,209 (59%), financing interest £9,206 (17%), charging £6,156 (11%), insurance £2,780 (5%), registration & fees £2,760 (5%), maintenance £1,500 (3%).
- Per mile, that is £0.54 of depreciation and £0.10 of charging, with £0.27 for everything else — £0.91/mile all-in.
- Charging vs the fleet: at £6,156 over 5 years the Audi Q4 e-tron 45 sits within £486 of the £5,670 median for the 27 EVs we price — nothing unusual either way.
