Under the bonnet

Manufacturer technical specifications. The power-to-weight ratio is the key physical factor in a drag race.

The start: 0 to 100 km/h

Off the line, the i5 eDrive40 hits 100 km/h in 6.12 s versus 7.46 s for the 320e. Despite the faster sprint time, the 320e is 6 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 i5 eDrive40 is doing 135 km/h against 115 km/h for the 320e. The gap is 0.32 s. The challenger starts to claw back ground.

At 400 metres standing start, the i5 eDrive40 crosses the line in 14.29 s versus 15.43 s. The 1.14 s gap represents roughly 44 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the i5 eDrive40 continues to build its lead. At 600 metres, it runs at 186 km/h versus 158 km/h. At 1,000 metres, the i5 eDrive40 finishes in 25.87 s versus 28.77 s, with a 2.90 s lead. Despite a higher top speed (215 km/h), the 320e never recovers its launch deficit.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the i5 eDrive40 is capped at 193 km/h, the 320e at 220 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 plug-in hybrid powertrains, the difference comes down to power-to-weight ratio (6.81 kg/hp vs 8.65 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.74 seconds. The 1.34 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
