The start: 0 to 100 km/h

Off the line, the 220i Gran Coupe hits 100 km/h in 7.04 s versus 7.48 s for the 420d xDrive. Despite the faster sprint time, the 420d xDrive is 1 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 220i Gran Coupe is doing 122 km/h against 117 km/h for the 420d xDrive. The gap is 0.08 s. The challenger starts to claw back ground.

At 400 metres standing start, the 220i Gran Coupe crosses the line in 15.11 s versus 15.43 s. The 0.32 s gap represents roughly 13 m of track - two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 220i Gran Coupe continues to build its lead. At 600 metres, it runs at 171 km/h versus 162 km/h. At 1,000 metres, the 220i Gran Coupe finishes in 27.42 s versus 28.37 s, with a 0.95 s lead. Both vehicles have similar top speeds (237 vs 238 km/h), preventing any comeback.

What the numbers don’t tell you

Both rivals share the same electronic speed cap: the 420d xDrive and the 220i Gran Coupe are governed to 238 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 (8.79 kg/hp vs 8.03 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.38 seconds. The 0.44 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
