Off the line, the 911 Targa 4 hits 100 km/h in 4.38 s versus 4.53 s for the 911 Targa 4S. The 0.15 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the 911 Targa 4 is doing 152 km/h against 150 km/h for the 911 Targa 4S. The gap is 0.06 s. The gap remains stable from the start.
At 400 metres standing start, the 911 Targa 4 crosses the line in 12.44 s versus 12.49 s. The 0.04 s gap represents roughly 2 m of track - barely a car length.
Past 400 metres, the situation changes. The 911 Targa 4 maxes out at 283 km/h while the 911 Targa 4S keeps accelerating towards 295 km/h. At 600 metres, the gap has dropped to 0.02 s.
Around 764 metres, both vehicles are level. This is the inversion point: the 911 Targa 4S overcomes its launch deficit thanks to a 12 km/h higher top speed.
At 1,000 metres, the 911 Targa 4S finishes in 22.38 s versus 22.44 s. The 0.06 s delta shows an extremely tight race.
Both rivals are electronically governed, but not at the same level: the 911 Targa 4S is capped at 295 km/h, the 911 Targa 4 at 288 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 (3.83 kg/hp vs 4.19 kg/hp) and transmission (Manual vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.68 seconds. The 0.15 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 911 Targa 4 991.2 wins (4,38 s vs 4,53 s).
911 Targa 4S 991.1 goes from 0 to 100 km/h in 4,53 seconds (calibrated simulation).
