Audi S5 Avant vs Bmw X2 M35i F39 : which one is faster?

The launch: 0 to 100 km/h

Off the line, the S5 Avant hits 100 km/h in 4.53 s versus 4.99 s for the Bmw X2 M35i. At this point, the S5 Avant leads by 0.46 s and sits roughly 6 m ahead.

From 100 km/h to 400 metres

At 200 metres, the S5 Avant is doing 142 km/h against 138 km/h for the Bmw X2 M35i. The gap is 0.33 s. The challenger starts to claw back ground.

At 400 metres standing start, the S5 Avant crosses the line in 12.83 s versus 13.30 s. The 0.47 s gap represents roughly 22 m of track — two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the S5 Avant continues to build its lead. At 600 metres, it runs at 197 km/h versus 190 km/h. At 1,000 metres, the S5 Avant finishes in 23.49 s versus 24.37 s, with a 0.89 s lead. Both vehicles have similar top speeds (250 vs 250 km/h), preventing any comeback.

What the numbers don’t tell you

Both rivals share the same electronic speed cap: the S5 Avant and the Bmw X2 M35i are governed to 250 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 (5.35 kg/hp vs 5.28 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.77 seconds. The 0.46 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
