Off the line, the 911 Turbo S Cabriolet hits 100 km/h in 2.95 s versus 3.46 s for the RS6 Performance Avant. At this point, the 911 Turbo S Cabriolet leads by 0.51 s and sits roughly 5 m ahead.
At 200 metres, the 911 Turbo S Cabriolet is doing 176 km/h against 165 km/h for the RS6 Performance Avant. The gap is 0.49 s. The gap remains stable from the start.
At 400 metres standing start, the 911 Turbo S Cabriolet crosses the line in 10.56 s versus 11.30 s. The 0.74 s gap represents roughly 42 m of track - a gap visible to the naked eye.
Past 400 metres, the 911 Turbo S Cabriolet continues to build its lead. At 600 metres, it runs at 246 km/h versus 231 km/h. At 1,000 metres, the 911 Turbo S Cabriolet finishes in 19.13 s versus 20.37 s, with a 1.24 s lead. Despite a higher top speed (346 km/h), the RS6 Performance Avant never recovers its launch deficit.
Electronically capped at 330 (i.e. 205 mph - industry threshold) km/h, the 911 Turbo S Cabriolet never reaches its natural aerodynamic ceiling in this duel. That’s not a physical limit of the motor - it’s a deliberate manufacturer decision, typically tied to standard-fit tyre ratings or model-range positioning.
With two combustion powertrains, the difference comes down to power-to-weight ratio (3.45 kg/hp vs 2.84 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 5.02 seconds. The 0.51 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 911 Turbo S Cabriolet 991.2 wins (2,95 s vs 3,46 s).
RS6 Performance Avant goes from 0 to 100 km/h in 3,46 seconds (calibrated simulation).
