The start: 0 to 100 km/h

Off the line, the M2 hits 100 km/h in 4.12 s versus 4.17 s for the 718 Cayman S. The 0.05 s gap is negligible: both vehicles are neck and neck.

From 100 km/h to 400 metres

At 200 metres, the M2 is doing 155 km/h against 156 km/h for the 718 Cayman S. The gap is 0.05 s. The gap remains stable from the start.

At 400 metres standing start, the M2 crosses the line in 12.08 s versus 12.12 s. The 0.04 s gap represents roughly 2 m of track - barely a car length.

Beyond 400 metres: top speed comes into play

Past 400 metres, nothing changes. Same ceiling, same acceleration, same trajectory - both rivals run in formation to the line. The 0.09 s gap at 1,000 metres confirms what the specs already suggested: on track, they’re interchangeable. The real contest happens elsewhere - range, comfort, charging network reliability.

What the numbers don’t tell you

Both rivals share the same electronic speed cap: the M2 and the 718 Cayman S are governed to 285 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 (3.76 kg/hp vs 3.87 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.01 seconds. The 0.05 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
