Lexus RZ
The Audi A6 Sportback e-tron costs £15,905 more than the Lexus RZ. For that premium it adds 110 miles more WLTP range, 120 kW faster peak rapid charging and 115 kW more power. On EVcarsguide's combined category scores, the Audi A6 Sportback e-tron comes out ahead overall.
The Lexus RZ is £15,905 cheaper to buy. Running costs are almost identical - about £144 a year either way, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the Lexus RZ comes out roughly £15,865 cheaper overall. These figures cover list price and home charging only - insurance, servicing, tyres and depreciation will move the real total.
EVcarsguide estimates a real-world motorway range of about 386 miles for the Audi A6 Sportback e-tron and 294 miles for the Lexus RZ - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Audi A6 Sportback e-tron goes roughly 92 miles further between charging stops. A rapid charge to 80% takes around 21 minutes in the Audi A6 Sportback e-tron and 30 in the Lexus RZ, so the Audi A6 Sportback e-tron loses less time at each stop. That makes the Audi A6 Sportback e-tron the stronger long-distance car.
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 518 mm of total clearance for the Audi A6 Sportback e-tron and about 505 mm of total clearance for the Lexus RZ. The Lexus RZ also turns in a 1.1 m tighter circle, which helps with U-turns and multi-storey ramps.
