The start: 0 to 100 km/h

Off the line, the i5 eDrive40 hits 100 km/h in 6.12 s versus 6.77 s for the Q4 45 e-tron 210 kW. At this point, the i5 eDrive40 leads by 0.65 s and sits roughly 2 m ahead.

From 100 km/h to 400 metres

At 200 metres, the i5 eDrive40 is doing 135 km/h against 125 km/h for the Q4 45 e-tron 210 kW. The gap is 0.33 s. The challenger starts to claw back ground.

At 400 metres standing start, the i5 eDrive40 crosses the line in 14.29 s versus 14.98 s. The 0.69 s gap represents roughly 29 m of track - two to three car lengths.

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 172 km/h. At 1,000 metres, the i5 eDrive40 finishes in 25.87 s versus 27.43 s, with a 1.57 s lead. Both vehicles have similar top speeds (193 vs 180 km/h), preventing any comeback.

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 Q4 45 e-tron 210 kW at 180 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 electric powertrains, the difference comes down to power-to-weight ratio (6.81 kg/hp vs 7.50 kg/hp) and transmission (Automatic vs Unknown).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 10.55 seconds. The 0.65 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
