The start: 0 to 100 km/h

Off the line, the 740i hits 100 km/h in 5.31 s versus 7.79 s for the A4 40 TDI. At this point, the 740i leads by 2.49 s and sits roughly 28 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 740i is doing 137 km/h against 122 km/h for the A4 40 TDI. The gap is 1.68 s. The challenger starts to claw back ground.

At 400 metres standing start, the 740i crosses the line in 13.53 s versus 15.77 s. The 2.24 s gap represents roughly 91 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 740i continues to build its lead. At 600 metres, it runs at 192 km/h versus 171 km/h. At 1,000 metres, the 740i finishes in 24.47 s versus 28.08 s, with a 3.62 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 242 km/h), preventing any comeback.

What the numbers don’t tell you

Electronically capped at 250 (i.e. 155 mph - industry threshold) km/h, the 740i never reaches its natural aerodynamic ceiling in this duel. That’s not a physical limit of the motor - it’s a deliberate manufacturer decision, typically tied to standard-fit tyre ratings or model-range positioning.

With two combustion powertrains, the difference comes down to power-to-weight ratio (5.49 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 11.76 seconds. The 2.49 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
