Off the line, the Z4 sDrive30i hits 100 km/h in 5.45 s versus 6.31 s for the P7i. Despite lacking instant torque, 258 hp of power compensates. At this point, the Z4 sDrive30i leads by 0.86 s and sits roughly 9 m ahead.
At 200 metres, the Z4 sDrive30i is doing 136 km/h against 129 km/h for the P7i. The gap is 0.56 s. The challenger starts to claw back ground.
At 400 metres standing start, the Z4 sDrive30i crosses the line in 13.70 s versus 14.56 s. The 0.86 s gap represents roughly 37 m of track - a gap visible to the naked eye.
Past 400 metres, the Z4 sDrive30i continues to build its lead. At 600 metres, it runs at 189 km/h versus 178 km/h. At 1,000 metres, the Z4 sDrive30i finishes in 24.81 s versus 26.38 s, with a 1.56 s lead.
Both rivals are electronically governed, but not at the same level: the P7i is capped at 200 km/h, the Z4 sDrive30i 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.
Instant electric torque gives an advantage off the line. The higher top speed of the combustion engine gives an advantage over longer distances. The distance at which one catches the other depends on the top speed differential.
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.78 seconds. The 0.86 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, Z4 sDrive30i G29 wins (5,45 s vs 6,31 s).
P7i goes from 0 to 100 km/h in 6,31 seconds (calibrated simulation).
