Off the line, the 420i Convertible hits 100 km/h in 8.14 s versus 8.28 s for the A 200 d. At this point, the 420i Convertible leads by 0.14 s and sits roughly 5 m ahead.
At 200 metres, the 420i Convertible is doing 115 km/h against 117 km/h for the A 200 d. The gap is 0.17 s. The gap remains stable from the start.
At 400 metres standing start, the 420i Convertible crosses the line in 15.96 s versus 16.10 s. The 0.13 s gap represents roughly 5 m of track - barely a car length.
Past 400 metres, the gap narrows. The A 200 d maxes out at 220 km/h while the 420i Convertible keeps accelerating towards 236 km/h. At 600 metres, the gap has dropped to 0.09 s.
At 1,000 metres, the 420i Convertible finishes in 28.97 s versus 29.00 s, with just 0.04 s to spare. The A 200 d fails to fully close the launch gap.
Both rivals are electronically governed, but not at the same level: the 420i Convertible is capped at 236 km/h, the A 200 d at 220 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 (9.18 kg/hp vs 9.53 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 13.11 seconds. The 0.14 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Swap one of the two models to explore an equivalent duel in the same segment.
