The start: 0 to 100 km/h

Off the line, the M2 hits 100 km/h in 4.12 s versus 4.53 s for the 911 Targa 4S. At this point, the M2 leads by 0.42 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 150 km/h for the 911 Targa 4S. The gap is 0.31 s. The challenger starts to claw back ground.

At 400 metres standing start, the M2 crosses the line in 12.08 s versus 12.49 s. The 0.41 s gap represents roughly 21 m of track - two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the M2 continues to build its lead. At 600 metres, it runs at 215 km/h versus 213 km/h. At 1,000 metres, the M2 finishes in 21.80 s versus 22.38 s, with a 0.58 s lead. Both vehicles have similar top speeds (285 vs 295 km/h), preventing any comeback.

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 911 Targa 4S at 295 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 3.83 kg/hp) and transmission (Automatic vs Manual).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.68 seconds. The 0.42 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
