The start: 0 to 100 km/h

Off the line, the S4 TDI hits 100 km/h in 4.84 s versus 6.53 s for the 630i Gran Turismo. At this point, the S4 TDI leads by 1.70 s and sits roughly 15 m ahead.

From 100 km/h to 400 metres

At 200 metres, the S4 TDI is doing 140 km/h against 125 km/h for the 630i Gran Turismo. The gap is 1.06 s. The challenger starts to claw back ground.

At 400 metres standing start, the S4 TDI crosses the line in 13.12 s versus 14.71 s. The 1.59 s gap represents roughly 67 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 175 km/h. At 1,000 metres, the S4 TDI finishes in 23.86 s versus 26.68 s, with a 2.83 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 250 (i.e. 155 mph - industry threshold) km/h), preventing any comeback.

What the numbers don’t tell you

Both rivals share the same electronic speed cap: the S4 TDI and the 630i Gran Turismo are governed to 250 (i.e. 155 mph - industry threshold) km/h. At that speed, standard-fit tyres approach their safety threshold - an industrial ceiling common to most electric vehicles in this segment. Neither car shows its true aerodynamic potential in this duel.

With two combustion powertrains, the difference comes down to power-to-weight ratio (5.10 kg/hp vs 6.92 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 10.28 seconds. The 1.70 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
