The start: 0 to 100 km/h

Off the line, the 225d hits 100 km/h in 6.40 s versus 7.28 s for the A4 40 TFSI. The 0.88 s gap is negligible: both vehicles are neck and neck.

From 100 km/h to 400 metres

At 200 metres, the 225d is doing 130 km/h against 119 km/h for the A4 40 TFSI. The gap is 0.31 s. The challenger starts to claw back ground.

At 400 metres standing start, the 225d crosses the line in 14.61 s versus 15.36 s. The 0.75 s gap represents roughly 30 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 225d continues to build its lead. At 600 metres, it runs at 180 km/h versus 165 km/h. At 1,000 metres, the 225d finishes in 26.28 s versus 28.08 s, with a 1.80 s lead. Both vehicles have similar top speeds (243 vs 232 km/h), preventing any comeback.

What the numbers don’t tell you

Electronically capped at 243 km/h, the 225d 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 (6.58 kg/hp vs 7.97 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.78 seconds. The 0.88 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
