Manufacturer technical specifications. The power-to-weight ratio is the key physical factor in a drag race.

The start: 0 to 100 km/h

Off the line, the RS 3 Sportback hits 100 km/h in 3.88 s versus 3.92 s for the Bmw i4 M50 xDrive. Despite lacking instant torque, 400 hp of power compensates. The 0.04 s gap is negligible: both vehicles are neck and neck.

From 100 km/h to 400 metres

At 200 metres, the RS 3 Sportback is doing 150 km/h against 155 km/h for the Bmw i4 M50 xDrive. The gap is 0.03 s. The gap remains stable from the start.

At 400 metres standing start, the Bmw i4 M50 xDrive crosses the line in 12.01 s versus 12.08 s. The 0.07 s gap represents roughly 4 m of track — barely a car length.

Beyond 400 metres: top speed comes into play

Past 400 metres, the Bmw i4 M50 xDrive continues to build its lead. At 600 metres, it runs at 216 km/h versus 211 km/h. At 1,000 metres, the Bmw i4 M50 xDrive finishes in 21.97 s versus 22.04 s, with a 0.08 s lead. Despite a higher top speed (250 (i.e. 155 mph — industry threshold) km/h), the RS 3 Sportback never recovers its launch deficit.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the Bmw i4 M50 xDrive is capped at 225 km/h, the RS 3 Sportback at 250 (i.e. 155 mph — industry threshold) 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 5.79 seconds. The 0.04 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
