Off the line, the 640i Gran Turismo hits 100 km/h in 5.49 s versus 7.46 s for the 320e. Despite lacking instant torque, 340 hp of power compensates. At this point, the 640i Gran Turismo leads by 1.97 s and sits roughly 6 m ahead.
At 200 metres, the 640i Gran Turismo is doing 137 km/h against 115 km/h for the 320e. The gap is 0.86 s. The challenger starts to claw back ground.
At 400 metres standing start, the 640i Gran Turismo crosses the line in 13.66 s versus 15.43 s. The 1.78 s gap represents roughly 68 m of track - a gap visible to the naked eye.
Past 400 metres, the 640i Gran Turismo continues to build its lead. At 600 metres, it runs at 192 km/h versus 158 km/h. At 1,000 metres, the 640i Gran Turismo finishes in 24.62 s versus 28.77 s, with a 4.15 s lead.
Both rivals are electronically governed, but not at the same level: the 640i Gran Turismo is capped at 250 (i.e. 155 mph - industry threshold) km/h, the 320e at 220 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 12.74 seconds. The 1.97 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 640i Gran Turismo G32 wins (5,49 s vs 7,46 s).
640i Gran Turismo G32 goes from 0 to 100 km/h in 5,49 seconds (calibrated simulation).
