Off the line, the 911 Targa 4 hits 100 km/h in 4.38 s versus 5.16 s for the 911 Targa 4. At this point, the 911 Targa 4 leads by 0.78 s and sits roughly 7 m ahead.
At 200 metres, the 911 Targa 4 is doing 152 km/h against 141 km/h for the 911 Targa 4. The gap is 0.53 s. The challenger starts to claw back ground.
At 400 metres standing start, the 911 Targa 4 crosses the line in 12.44 s versus 13.20 s. The 0.76 s gap represents roughly 37 m of track - a gap visible to the naked eye.
Past 400 metres, the 911 Targa 4 continues to build its lead. At 600 metres, it runs at 211 km/h versus 201 km/h. At 1,000 metres, the 911 Targa 4 finishes in 22.44 s versus 23.67 s, with a 1.23 s lead. Both vehicles have similar top speeds (283 vs 281 km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the 911 Targa 4 is capped at 288 km/h, the 911 Targa 4 at 282 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 (4.19 kg/hp vs 4.34 kg/hp) and transmission (Automatic vs Manual).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.68 seconds. The 0.78 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 5,16 s).
911 Targa 4 991.2 goes from 0 to 100 km/h in 4,38 seconds (calibrated simulation).
