The start: 0 to 100 km/h

Off the line, the 218d xDrive hits 100 km/h in 8.92 s versus 9.12 s for the 218d Convertible. Despite the faster sprint time, the 218d Convertible is 8 m further along the track at this moment: stronger low-speed acceleration offsets a slower run beyond 100 km/h.

From 100 km/h to 400 metres

At 200 metres, the 218d Convertible is doing 109 km/h against 113 km/h for the 218d xDrive. The gap is 0.22 s. The gap remains stable from the start.

At 400 metres standing start, the 218d Convertible crosses the line in 16.65 s versus 16.67 s. The 0.02 s gap represents roughly 1 m of track

Beyond 400 metres: top speed comes into play

Past 400 metres, the situation changes. Past 400 metres, both rivals hit the same electronic ceiling at 208 km/h. Neither can claw back ground through top speed - the outcome hinges on the acceleration curve between 100 and 208 km/h.

At 1,000 metres, the 218d xDrive finishes in 30.09 s versus 30.48 s. The 0.39 s delta shows an extremely tight race.

What the numbers don’t tell you

Both rivals share the same electronic speed cap: the 218d Convertible and the 218d xDrive are governed to 208 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 (10.43 kg/hp vs 10.13 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 15.20 seconds. The 0.20 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
