The start: 0 to 100 km/h

Off the line, the 911 Turbo hits 100 km/h in 3.35 s versus 3.53 s for the 911 Turbo. At this point, the 911 Turbo leads by 0.18 s and sits roughly 3 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 911 Turbo is doing 168 km/h against 168 km/h for the 911 Turbo. The gap is 0.13 s. The gap remains stable from the start.

At 400 metres standing start, the 911 Turbo crosses the line in 11.13 s versus 11.25 s. The 0.12 s gap represents roughly 7 m of track - barely a car length.

Beyond 400 metres: top speed comes into play

Past 400 metres, the gap narrows.

At 1,000 metres, the 911 Turbo finishes in 20.22 s versus 20.27 s, with just 0.06 s to spare. The 911 Turbo fails to fully close the launch gap.

What the numbers don’t tell you

Both rivals share the same electronic speed cap: the 911 Turbo and the 911 Turbo are governed to 312 km/h. At that speed, standard-fit tyres approach their safety threshold - an industrial ceiling common to most electric vehicles in this segment. Neither car shows its true aerodynamic potential in this duel.

With two combustion powertrains, the difference comes down to power-to-weight ratio (3.10 kg/hp vs 3.10 kg/hp) and transmission (Unknown vs Unknown).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 4.99 seconds. The 0.18 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
