Off the line, the Bmw 740Le iPerformance hits 100 km/h in 5.58 s versus 8.14 s for the Bmw 420i Convertible. The instant torque of 400 Nm from the electric motor makes the difference. At this point, the Bmw 740Le iPerformance leads by 2.56 s and sits roughly 23 m ahead.
At 200 metres, the Bmw 740Le iPerformance is doing 132 km/h against 115 km/h for the Bmw 420i Convertible. The gap is 1.46 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw 740Le iPerformance crosses the line in 13.77 s versus 15.96 s. The 2.19 s gap represents roughly 84 m of track - a gap visible to the naked eye.
Past 400 metres, the Bmw 740Le iPerformance continues to build its lead. At 600 metres, it runs at 186 km/h versus 161 km/h. At 1,000 metres, the Bmw 740Le iPerformance finishes in 25.05 s versus 28.97 s, with a 3.92 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 236 km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the Bmw 740Le iPerformance is capped at 250 (i.e. 155 mph - industry threshold) km/h, the Bmw 420i Convertible at 236 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 13.10 seconds. The 2.56 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 740Le iPerformance G11 wins (5,58 s vs 8,14 s).
740Le iPerformance G11 goes from 0 to 100 km/h in 5,58 seconds (calibrated simulation).
