911 Targa 4 GTS vs Bmw 745Le: chronicle of a drag race at 307 km/h
The launch: 0 to 100 km/h
Off the line, the 911 Targa 4 GTS hits 100 km/h in 3.66 s versus 5.36 s for the Bmw 745Le. At this point, the 911 Targa 4 GTS leads by 1.71 s and sits roughly 17 m ahead.
From 100 km/h to 400 metres
At 200 metres, the 911 Targa 4 GTS is doing 162 km/h against 141 km/h for the Bmw 745Le. The gap is 1.36 s. The challenger starts to claw back ground.
At 400 metres standing start, the 911 Targa 4 GTS crosses the line in 11.57 s versus 13.47 s. The 1.90 s gap represents roughly 90 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the 911 Targa 4 GTS continues to build its lead. At 600 metres, it runs at 224 km/h versus 200 km/h. At 1,000 metres, the 911 Targa 4 GTS finishes in 20.93 s versus 23.97 s, with a 3.03 s lead.
What the numbers don’t tell you
The 911 Targa 4 GTS features all-wheel drive (AWD) against the Bmw 745Le’s RWD. At low speeds (0-30, 0-50, 0-80 km/h), AWD doubles the driven contact area: all four wheels transmit torque to the road, virtually eliminating wheelspin at launch. This traction advantage is decisive in the range where the motor delivers peak torque, before power and aerodynamics take over.
Both rivals are electronically governed, but not at the same level: the 911 Targa 4 GTS is capped at 307 km/h, the Bmw 745Le at 250 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 (3.48 kg/hp vs 5.19 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.84 seconds. The 1.71 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche 911 Targa 4 GTS has a clear edge over the Bmw 745Le to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
