The start: 0 to 100 km/h

Off the line, the i7 M70 xDrive hits 100 km/h in 3.65 s versus 5.91 s for the 330e. At this point, the i7 M70 xDrive leads by 2.27 s and sits roughly 20 m ahead.

From 100 km/h to 400 metres

At 200 metres, the i7 M70 xDrive is doing 155 km/h against 134 km/h for the 330e. The gap is 1.66 s. The challenger starts to claw back ground.

At 400 metres standing start, the i7 M70 xDrive crosses the line in 11.83 s versus 14.09 s. The 2.26 s gap represents roughly 101 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the i7 M70 xDrive continues to build its lead. At 600 metres, it runs at 214 km/h versus 188 km/h. At 1,000 metres, the i7 M70 xDrive finishes in 21.61 s versus 25.24 s, with a 3.63 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the i7 M70 xDrive is capped at 250 (i.e. 155 mph - industry threshold) km/h, the 330e at 230 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 (4.24 kg/hp vs 6.06 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.90 seconds. The 2.27 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
