The start: 0 to 100 km/h

Off the line, the S 450 4MATIC Saloon, long version hits 100 km/h in 4.86 s versus 7.00 s for the A6 Avant. At this point, the S 450 4MATIC Saloon, long version leads by 2.14 s and sits roughly 10 m ahead.

From 100 km/h to 400 metres

At 200 metres, the S 450 4MATIC Saloon, long version is doing 138 km/h against 117 km/h for the A6 Avant. The gap is 1.07 s. The challenger starts to claw back ground.

At 400 metres standing start, the S 450 4MATIC Saloon, long version crosses the line in 13.08 s versus 15.02 s. The 1.94 s gap represents roughly 75 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the S 450 4MATIC Saloon, long version continues to build its lead. At 600 metres, it runs at 196 km/h versus 161 km/h. At 1,000 metres, the S 450 4MATIC Saloon, long version finishes in 23.76 s versus 27.98 s, with a 4.22 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 238 km/h), preventing any comeback.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the S 450 4MATIC Saloon, long version is capped at 250 (i.e. 155 mph - industry threshold) km/h, the A6 Avant 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.

With two combustion powertrains, the difference comes down to power-to-weight ratio (5.73 kg/hp vs 9.80 kg/hp) and transmission (Unknown vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.76 seconds. The 2.14 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
