The start: 0 to 100 km/h

Off the line, the 330d Touring hits 100 km/h in 5.53 s versus 7.44 s for the 420i. At this point, the 330d Touring leads by 1.91 s and sits roughly 14 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 330d Touring is doing 131 km/h against 117 km/h for the 420i. The gap is 0.97 s. The challenger starts to claw back ground.

At 400 metres standing start, the 330d Touring crosses the line in 13.83 s versus 15.38 s. The 1.55 s gap represents roughly 61 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 330d Touring continues to build its lead. At 600 metres, it runs at 182 km/h versus 163 km/h. At 1,000 metres, the 330d Touring finishes in 25.34 s versus 28.23 s, with a 2.89 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 238 km/h), preventing any comeback.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the 330d Touring is capped at 250 (i.e. 155 mph - industry threshold) km/h, the 420i at 240 km/h. This isn’t a physical engine limit - it’s a manufacturer choice, usually for tyre safety or homologation reasons. Neither car reaches its true aerodynamic top speed.

With two combustion powertrains, the difference comes down to power-to-weight ratio (6.47 kg/hp vs 8.29 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.15 seconds. The 1.91 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
