Off the line, the Bmw Z4 sDrive30i hits 100 km/h in 5.45 s versus 8.35 s for the Bmw 118d. At this point, the Bmw Z4 sDrive30i leads by 2.90 s and sits roughly 21 m ahead.
At 200 metres, the Bmw Z4 sDrive30i is doing 136 km/h against 115 km/h for the Bmw 118d. The gap is 1.61 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw Z4 sDrive30i crosses the line in 13.70 s versus 16.20 s. The 2.49 s gap represents roughly 95 m of track - a gap visible to the naked eye.
Past 400 metres, the Bmw Z4 sDrive30i continues to build its lead. At 600 metres, it runs at 189 km/h versus 159 km/h. At 1,000 metres, the Bmw Z4 sDrive30i finishes in 24.81 s versus 29.44 s, with a 4.63 s lead.
Both rivals are electronically governed, but not at the same level: the Bmw Z4 sDrive30i is capped at 250 (i.e. 155 mph - industry threshold) km/h, the Bmw 118d at 218 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 (5.54 kg/hp vs 9.33 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 13.49 seconds. The 2.90 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 8,35 s).
Z4 sDrive30i G29 goes from 0 to 100 km/h in 5,45 seconds (calibrated simulation).
