The start: 0 to 100 km/h

Off the line, the 320d Steptronic hits 100 km/h in 6.97 s versus 7.79 s for the A5 Sedan. At this point, the 320d Steptronic leads by 0.82 s and sits roughly 11 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 320d Steptronic is doing 120 km/h against 117 km/h for the A5 Sedan. The gap is 0.51 s. The challenger starts to claw back ground.

At 400 metres standing start, the 320d Steptronic crosses the line in 15.10 s versus 15.74 s. The 0.63 s gap represents roughly 25 m of track - two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 320d Steptronic continues to build its lead. At 600 metres, it runs at 167 km/h versus 162 km/h. At 1,000 metres, the 320d Steptronic finishes in 27.70 s versus 28.62 s, with a 0.92 s lead. Both vehicles have similar top speeds (242 vs 237 km/h), preventing any comeback.

What the numbers don’t tell you

Both rivals share the same electronic speed cap: the A5 Sedan and the 320d Steptronic are governed to 242 km/h. At that speed, standard-fit tyres approach their safety threshold - an industrial ceiling common to most electric vehicles in this segment. Neither car shows its true aerodynamic potential in this duel.

With two combustion powertrains, the difference comes down to power-to-weight ratio (8.92 kg/hp vs 7.66 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.41 seconds. The 0.82 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
