The start: 0 to 100 km/h

Off the line, the 911 Turbo hits 100 km/h in 3.04 s versus 3.34 s for the RS e-tron GT. Despite lacking instant torque, 547 hp of power compensates. At this point, the 911 Turbo leads by 0.30 s and sits roughly 5 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 911 Turbo is doing 171 km/h against 167 km/h for the RS e-tron GT. The gap is 0.27 s. The gap remains stable from the start.

At 400 metres standing start, the 911 Turbo crosses the line in 10.79 s versus 11.17 s. The 0.38 s gap represents roughly 22 m of track - two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 911 Turbo continues to build its lead. At 600 metres, it runs at 238 km/h versus 233 km/h. At 1,000 metres, the 911 Turbo finishes in 19.64 s versus 20.27 s, with a 0.63 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the RS e-tron GT is capped at 250 (i.e. 155 mph - industry threshold) km/h, the 911 Turbo at 319 km/h. This isn’t a physical engine limit - it’s a manufacturer choice, usually for tyre safety or homologation reasons. Neither car reaches its true aerodynamic top speed.

Instant electric torque gives an advantage off the line. The higher top speed of the combustion engine gives an advantage over longer distances. The distance at which one catches the other depends on the top speed differential.

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 4.78 seconds. The 0.30 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
