Audi Q8 Sportback e-tron vs Porsche Macan Electric

The Audi Q8 Sportback e-tron costs £1,700 more than the Porsche Macan Electric. On the headline specs that premium buys little measurable advantage - the two are closely matched on range, charging and space. The Porsche Macan Electric is not just cheaper - it also offers 108 miles more WLTP range and 120 kW faster peak rapid charging. On EVcarsguide's combined category scores, the Porsche Macan Electric comes out ahead overall.

The Porsche Macan Electric is £1,700 cheaper to buy. The Porsche Macan Electric is cheaper to charge, roughly £168 a year versus £224 for the Audi Q8 Sportback e-tron, at 8,000 miles on an off-peak home tariff.

EVcarsguide estimates a real-world motorway range of about 242 miles for the Audi Q8 Sportback e-tron and 332 miles for the Porsche Macan Electric - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Porsche Macan Electric goes roughly 90 miles further between charging stops. A rapid charge to 80% takes around 31 minutes in the Audi Q8 Sportback e-tron and 21 in the Porsche Macan Electric, so the Porsche Macan Electric loses less time at each stop. That makes the Porsche Macan Electric the stronger long-distance car.

The two are within 3 mm on width, so neither is meaningfully easier to thread into a tight space. In a standard 2,400 mm bay that leaves about 465 mm of total clearance for the Audi Q8 Sportback e-tron and about 462 mm of total clearance for the Porsche Macan Electric.

Over a 8-year ownership window EVcarsguide's degradation model projects roughly 84% battery health for the Audi Q8 Sportback e-tron and 84% for the Porsche Macan Electric. 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.
