The start: 0 to 100 km/h

Off the line, the RS 3 Sedan hits 100 km/h in 3.85 s versus 7.04 s for the 420d. At this point, the RS 3 Sedan leads by 3.19 s and sits roughly 16 m ahead.

From 100 km/h to 400 metres

At 200 metres, the RS 3 Sedan is doing 151 km/h against 119 km/h for the 420d. The gap is 1.91 s. The challenger starts to claw back ground.

At 400 metres standing start, the RS 3 Sedan crosses the line in 12.04 s versus 15.10 s. The 3.06 s gap represents roughly 119 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the RS 3 Sedan continues to build its lead. At 600 metres, it runs at 212 km/h versus 166 km/h. At 1,000 metres, the RS 3 Sedan finishes in 21.96 s versus 27.77 s, with a 5.82 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 240 km/h), preventing any comeback.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the RS 3 Sedan is capped at 250 (i.e. 155 mph - industry threshold) km/h, the 420d at 240 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.

With two combustion powertrains, the difference comes down to power-to-weight ratio (3.91 kg/hp vs 8.45 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.60 seconds. The 3.19 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
