The start: 0 to 100 km/h

Off the line, the 330i hits 100 km/h in 5.88 s versus 6.03 s for the C 300. The 0.15 s gap is negligible: both vehicles are neck and neck.

From 100 km/h to 400 metres

At 200 metres, the 330i is doing 135 km/h against 132 km/h for the C 300. The gap is 0.10 s. The gap remains stable from the start.

At 400 metres standing start, the 330i crosses the line in 14.04 s versus 14.22 s. The 0.18 s gap represents roughly 8 m of track - barely a car length.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 330i continues to build its lead. At 600 metres, it runs at 190 km/h versus 186 km/h. At 1,000 metres, the 330i finishes in 25.09 s versus 25.46 s, with a 0.38 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 250 (i.e. 155 mph - industry threshold) km/h), preventing any comeback.

What the numbers don’t tell you

Both rivals share the same electronic speed cap: the 330i and the C 300 are governed to 250 (i.e. 155 mph - industry threshold) 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 (5.70 kg/hp vs 6.36 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.14 seconds. The 0.15 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
