Off the line, the Z4 M40i hits 100 km/h in 4.55 s versus 5.16 s for the 911 Targa 4. At this point, the Z4 M40i leads by 0.62 s and sits roughly 6 m ahead.
At 200 metres, the Z4 M40i is doing 147 km/h against 141 km/h for the 911 Targa 4. The gap is 0.39 s. The challenger starts to claw back ground.
At 400 metres standing start, the Z4 M40i crosses the line in 12.71 s versus 13.20 s. The 0.49 s gap represents roughly 24 m of track - two to three car lengths.
Past 400 metres, the Z4 M40i continues to build its lead. At 600 metres, it runs at 204 km/h versus 201 km/h. At 1,000 metres, the Z4 M40i finishes in 23.00 s versus 23.67 s, with a 0.68 s lead. Despite a higher top speed (281 km/h), the 911 Targa 4 never recovers its launch deficit.
Both rivals are electronically governed, but not at the same level: the 911 Targa 4 is capped at 282 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 (4.34 kg/hp vs 4.57 kg/hp) and transmission (Manual vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.68 seconds. The 0.62 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.
Over 0–100 km/h, Z4 M40i G29 wins (4,54 s vs 5,16 s).
