EVcarsguide estimates a real-world motorway range of about 246 miles for the Audi RS e-tron GT and 305 miles for the Mercedes-Benz EQS SUV - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Mercedes-Benz EQS SUV goes roughly 59 miles further between charging stops.

Which is easier to park and drive in town, the Audi RS e-tron GT or the Mercedes-Benz EQS SUV?
The two are within 5 mm on width, so neither is meaningfully easier to thread into a tight space. In a standard 2,400 mm bay that leaves about 441 mm of total clearance for the Mercedes-Benz EQS SUV and about 436 mm of total clearance for the Audi RS e-tron GT. The Audi RS e-tron GT also turns in a 0.3 m tighter circle, which helps with U-turns and multi-storey ramps.

Over a 8-year ownership window EVcarsguide's degradation model projects roughly 84% battery health for the Audi RS e-tron GT and 84% for the Mercedes-Benz EQS SUV. 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.
