The start: 0 to 100 km/h

Off the line, the RS 5 Avant hits 100 km/h in 3.66 s versus 7.74 s for the 420i xDrive. The instant torque of 825 Nm from the electric motor makes the difference. At this point, the RS 5 Avant leads by 4.09 s and sits roughly 19 m ahead.

From 100 km/h to 400 metres

At 200 metres, the RS 5 Avant is doing 156 km/h against 115 km/h for the 420i xDrive. The gap is 2.41 s. The challenger starts to claw back ground.

At 400 metres standing start, the RS 5 Avant crosses the line in 11.72 s versus 15.61 s. The 3.89 s gap represents roughly 144 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the RS 5 Avant continues to build its lead. At 600 metres, it runs at 218 km/h versus 160 km/h. At 1,000 metres, the RS 5 Avant finishes in 21.35 s versus 28.71 s, with a 7.36 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the RS 5 Avant is capped at 250 (i.e. 155 mph - industry threshold) km/h, the 420i xDrive at 238 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 12.85 seconds. The 4.09 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
