Off the line, the 911 Targa 4S hits 100 km/h in 4.05 s versus 7.75 s for the Bmw 420d Convertible. At this point, the 911 Targa 4S leads by 3.71 s and sits roughly 16 m ahead.
At 200 metres, the 911 Targa 4S is doing 158 km/h against 116 km/h for the Bmw 420d Convertible. The gap is 2.16 s. The challenger starts to claw back ground.
At 400 metres standing start, the 911 Targa 4S crosses the line in 11.99 s versus 15.64 s. The 3.65 s gap represents roughly 136 m of track - a gap visible to the naked eye.
Past 400 metres, the 911 Targa 4S continues to build its lead. At 600 metres, it runs at 219 km/h versus 161 km/h. At 1,000 metres, the 911 Targa 4S finishes in 21.58 s versus 28.69 s, with a 7.11 s lead.
Both rivals are electronically governed, but not at the same level: the 911 Targa 4S is capped at 303 km/h, the Bmw 420d Convertible at 236 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 (3.71 kg/hp vs 9.34 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.82 seconds. The 3.71 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 911 Targa 4S 991.2 wins (4,04 s vs 7,75 s).
