Off the line, the X7 xDrive50i hits 100 km/h in 5.33 s versus 6.80 s for the 225xe iPerformance. Despite lacking instant torque, 462 hp of power compensates. At this point, the X7 xDrive50i leads by 1.47 s and sits roughly 18 m ahead.
At 200 metres, the X7 xDrive50i is doing 137 km/h against 126 km/h for the 225xe iPerformance. The gap is 1.01 s. The challenger starts to claw back ground.
At 400 metres standing start, the X7 xDrive50i crosses the line in 13.57 s versus 14.96 s. The 1.39 s gap represents roughly 59 m of track - a gap visible to the naked eye.
Past 400 metres, the X7 xDrive50i continues to build its lead. At 600 metres, it runs at 190 km/h versus 176 km/h. At 1,000 metres, the X7 xDrive50i finishes in 24.64 s versus 26.93 s, with a 2.29 s lead.
Both rivals are electronically governed, but not at the same level: the X7 xDrive50i is capped at 250 (i.e. 155 mph - industry threshold) km/h, the 225xe iPerformance at 202 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 10.41 seconds. The 1.47 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, X7 xDrive50i G07 wins (5,33 s vs 6,80 s).
X7 xDrive50i G07 goes from 0 to 100 km/h in 5,33 seconds (calibrated simulation).
