Bmw ActiveHybrid X6 vs 911 Targa 4S: chronicle of a drag race at 295 km/h
The launch: 0 to 100 km/h
Off the line, the 911 Targa 4S hits 100 km/h in 4.53 s versus 5.60 s for the Bmw ActiveHybrid X6. At this point, the 911 Targa 4S leads by 1.06 s and sits roughly 15 m ahead.
From 100 km/h to 400 metres
At 200 metres, the 911 Targa 4S is doing 150 km/h against 141 km/h for the Bmw ActiveHybrid X6. The gap is 0.87 s. The challenger starts to claw back ground.
At 400 metres standing start, the 911 Targa 4S crosses the line in 12.49 s versus 13.66 s. The 1.17 s gap represents roughly 56 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the 911 Targa 4S continues to build its lead. At 600 metres, it runs at 213 km/h versus 198 km/h. At 1,000 metres, the 911 Targa 4S finishes in 22.38 s versus 24.29 s, with a 1.91 s lead.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the Bmw ActiveHybrid X6 is capped at 236 km/h, the 911 Targa 4S at 295 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 (5.05 kg/hp vs 3.83 kg/hp) and transmission (Automatic vs Manual).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.07 seconds. The 1.06 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche 911 Targa 4S has a clear edge over the Bmw ActiveHybrid X6 to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
