Off the line, the Z4 sDrive30i hits 100 km/h in 5.45 s versus 6.58 s for the P7. Despite lacking instant torque, 258 hp of power compensates. At this point, the Z4 sDrive30i leads by 1.13 s and sits roughly 13 m ahead.
At 200 metres, the Z4 sDrive30i is doing 136 km/h against 127 km/h for the P7. The gap is 0.74 s. The challenger starts to claw back ground.
At 400 metres standing start, the Z4 sDrive30i crosses the line in 13.70 s versus 14.81 s. The 1.11 s gap represents roughly 47 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 170 km/h. At 1,000 metres, the Z4 sDrive30i finishes in 24.81 s versus 27.64 s, with a 2.83 s lead.
Both rivals are electronically governed, but not at the same level: the P7 is capped at 170 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 10.18 seconds. The 1.13 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 6,58 s).
P7 goes from 0 to 100 km/h in 6,58 seconds (calibrated simulation).
