The start: 0 to 100 km/h

Off the line, the S4 TDI hits 100 km/h in 4.84 s versus 8.32 s for the V 300 d 4MATIC (long). At this point, the S4 TDI leads by 3.49 s and sits roughly 19 m ahead.

From 100 km/h to 400 metres

At 200 metres, the S4 TDI is doing 140 km/h against 114 km/h for the V 300 d 4MATIC (long). The gap is 1.77 s. The challenger starts to claw back ground.

At 400 metres standing start, the S4 TDI crosses the line in 13.12 s versus 16.03 s. The 2.91 s gap represents roughly 107 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the S4 TDI continues to build its lead. At 600 metres, it runs at 195 km/h versus 156 km/h. At 1,000 metres, the S4 TDI finishes in 23.86 s versus 29.55 s, with a 5.70 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the S4 TDI is capped at 250 (i.e. 155 mph - industry threshold) km/h, the V 300 d 4MATIC (long) at 217 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 (5.10 kg/hp vs 9.44 kg/hp) and transmission (Automatic vs Unknown).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 14.08 seconds. The 3.49 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
