Off the line, the 420i Steptronic Gran Coupe hits 100 km/h in 7.62 s versus 8.36 s for the 9 E-Tense 250. Despite lacking instant torque, 184 hp of power compensates. At this point, the 420i Steptronic Gran Coupe leads by 0.74 s and sits roughly 24 m ahead.
At 200 metres, the 420i Steptronic Gran Coupe is doing 118 km/h against 121 km/h for the 9 E-Tense 250. The gap is 0.85 s. The gap remains stable from the start.
At 400 metres standing start, the 420i Steptronic Gran Coupe crosses the line in 15.55 s versus 16.22 s. The 0.67 s gap represents roughly 28 m of track - two to three car lengths.
Past 400 metres, the gap narrows.
At 1,000 metres, the 420i Steptronic Gran Coupe finishes in 28.34 s versus 28.57 s, with just 0.23 s to spare. The 9 E-Tense 250 fails to fully close the launch gap.
Electronically capped at 236 km/h, the 420i Steptronic Gran Coupe never reaches its natural aerodynamic ceiling in this duel. That’s not a physical limit of the motor - it’s a deliberate manufacturer decision, typically tied to standard-fit tyre ratings or model-range positioning.
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 12.32 seconds. The 0.74 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 420i Steptronic Gran Coupe G22 wins (7,62 s vs 8,36 s).
