Off the line, the 911 Turbo hits 100 km/h in 3.04 s versus 4.54 s for the Z4 M40i. At this point, the 911 Turbo leads by 1.50 s and sits roughly 14 m ahead.
At 200 metres, the 911 Turbo is doing 171 km/h against 147 km/h for the Z4 M40i. The gap is 1.30 s. The challenger starts to claw back ground.
At 400 metres standing start, the 911 Turbo crosses the line in 10.79 s versus 12.70 s. The 1.91 s gap represents roughly 93 m of track - a gap visible to the naked eye.
Past 400 metres, the 911 Turbo continues to build its lead. At 600 metres, it runs at 238 km/h versus 205 km/h. At 1,000 metres, the 911 Turbo finishes in 19.64 s versus 22.95 s, with a 3.30 s lead.
Both rivals are electronically governed, but not at the same level: the 911 Turbo is capped at 319 km/h, the Z4 M40i at 250 (i.e. 155 mph - industry threshold) 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 (2.92 kg/hp vs 4.51 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.76 seconds. The 1.50 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Swap one of the two models to explore an equivalent duel in the same segment.
