The start: 0 to 100 km/h

Off the line, the 120i hits 100 km/h in 7.12 s versus 8.08 s for the A 200. At this point, the 120i leads by 0.96 s and sits roughly 20 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 120i is doing 122 km/h against 121 km/h for the A 200. The gap is 0.79 s. The challenger starts to claw back ground.

At 400 metres standing start, the 120i crosses the line in 15.22 s versus 16.05 s. The 0.83 s gap represents roughly 34 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 120i continues to build its lead. At 600 metres, it runs at 170 km/h versus 170 km/h. At 1,000 metres, the 120i finishes in 27.52 s versus 28.42 s, with a 0.90 s lead. Both vehicles have similar top speeds (225 vs 225 km/h), preventing any comeback.

What the numbers don’t tell you

Both rivals share the same electronic speed cap: the 120i and the A 200 are governed to 225 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 (7.47 kg/hp vs 8.44 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.11 seconds. The 0.96 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
