Bmw 750Ld xDrive vs 911 Targa 4: chronicle of a drag race at 281 km/h
The launch: 0 to 100 km/h
Off the line, the Bmw 750Ld xDrive hits 100 km/h in 4.63 s versus 5.16 s for the 911 Targa 4. At this point, the Bmw 750Ld xDrive leads by 0.53 s and sits roughly 6 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Bmw 750Ld xDrive is doing 145 km/h against 141 km/h for the 911 Targa 4. The gap is 0.33 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw 750Ld xDrive crosses the line in 12.84 s versus 13.20 s. The 0.37 s gap represents roughly 18 m of track — two to three car lengths.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Bmw 750Ld xDrive continues to build its lead. At 600 metres, it runs at 203 km/h versus 201 km/h. At 1,000 metres, the Bmw 750Ld xDrive finishes in 23.18 s versus 23.67 s, with a 0.50 s lead. Despite a higher top speed (281 km/h), the 911 Targa 4 never recovers its launch deficit.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the Bmw 750Ld xDrive is capped at 250 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 (4.95 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 0.53 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Bmw 750Ld xDrive is slightly faster than the Porsche 911 Targa 4 to 100 km/h. The edge holds on standing starts but may narrow at higher speeds depending on aerodynamic load.
