The start: 0 to 100 km/h

Off the line, the 330d hits 100 km/h in 5.40 s versus 5.49 s for the 640i Gran Turismo. The 0.09 s gap is negligible: both vehicles are neck and neck.

From 100 km/h to 400 metres

At 200 metres, the 330d is doing 134 km/h against 137 km/h for the 640i Gran Turismo. The gap is 0.08 s. The gap remains stable from the start.

At 400 metres standing start, the 640i Gran Turismo crosses the line in 13.66 s versus 13.68 s. The 0.02 s gap represents roughly 1 m of track

Beyond 400 metres: top speed comes into play

Past 400 metres, the 640i Gran Turismo continues to build its lead. At 600 metres, it runs at 192 km/h versus 187 km/h. At 1,000 metres, the 640i Gran Turismo finishes in 24.62 s versus 24.90 s, with a 0.28 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 640i Gran Turismo and the 330d 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 (5.21 kg/hp vs 6.00 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.44 seconds. The 0.09 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
