The start: 0 to 100 km/h

Off the line, the 330d Touring hits 100 km/h in 5.53 s versus 5.65 s for the C 300 d. The 0.12 s gap is negligible: both vehicles are neck and neck.

From 100 km/h to 400 metres

At 200 metres, the 330d Touring is doing 131 km/h against 131 km/h for the C 300 d. The gap is 0.05 s. The gap remains stable from the start.

At 400 metres standing start, the 330d Touring crosses the line in 13.83 s versus 13.88 s. The 0.05 s gap represents roughly 2 m of track - barely a car length.

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 250 (i.e. 155 mph - industry threshold) km/h. Neither can claw back ground through top speed - the outcome hinges on the acceleration curve between 100 and 250 (i.e. 155 mph - industry threshold) km/h.

At 1,000 metres, the C 300 d finishes in 25.26 s versus 25.34 s. The 0.08 s delta shows an extremely tight race.

What the numbers don’t tell you

Both rivals share the same electronic speed cap: the 330d Touring and the C 300 d 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 (6.47 kg/hp vs 6.28 kg/hp) and transmission (Automatic vs Unknown).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.87 seconds. The 0.12 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
