Under the bonnet

Manufacturer technical specifications. The power-to-weight ratio is the key physical factor in a drag race.

The start: 0 to 100 km/h

Off the line, the M2 hits 100 km/h in 4.12 s versus 4.47 s for the 718 Cayman GTS. At this point, the M2 leads by 0.35 s and sits roughly 4 m ahead.

From 100 km/h to 400 metres

At 200 metres, the M2 is doing 155 km/h against 155 km/h for the 718 Cayman GTS. The gap is 0.23 s. The challenger starts to claw back ground.

At 400 metres standing start, the M2 crosses the line in 12.08 s versus 12.32 s. The 0.24 s gap represents roughly 13 m of track — two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the gap narrows. The M2 maxes out at 285 km/h while the 718 Cayman GTS keeps accelerating towards 290 km/h. At 600 metres, the gap has dropped to 0.20 s.

At 1,000 metres, the M2 finishes in 21.80 s versus 21.96 s, with just 0.16 s to spare. The 718 Cayman GTS fails to fully close the launch gap.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the M2 is capped at 285 km/h, the 718 Cayman GTS at 290 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.

With two combustion powertrains, the difference comes down to power-to-weight ratio (3.76 kg/hp vs 3.77 kg/hp) and transmission (Automatic vs Manual).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.41 seconds. The 0.35 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
