BMW 520d (G30) vs BMW 5 Series 520i 184

Over a standing quarter mile on dry asphalt the BMW 520d (G30) is the quicker car, covering it in 15.15 s at 92.3 mph against the BMW 5 Series 520i 184’s 15.45 s — a margin of 0.30 s. To 60 mph the BMW 520d (G30) takes 6.77 s and the BMW 5 Series 520i 184 7.12 s.

Simulated, not measured — computed from each car’s published kerb mass, rated power and drivetrain, then fitted to its own published acceleration figures. Dry asphalt, 20 °C, sea level, 1 ft rollout.

Questions

Is the BMW 520d (G30) or the BMW 5 Series 520i 184 faster?
The BMW 520d (G30). Over a standing quarter mile it runs 15.15 s to the BMW 5 Series 520i 184's 15.45 s, a margin of 0.30 s, and it reaches 60 mph in 6.77 s against 7.12 s. These are theoretical times from a physics simulation, not measured runs.
What is the BMW 520d (G30) 0-60 time?
The BMW 520d (G30) reaches 60 mph in 6.77 s, simulated on dry asphalt at 20 °C with a 1 ft rollout. It covers the standing quarter mile in 15.15 s at 92.3 mph.
What is the BMW 5 Series 520i 184 0-60 time?
The BMW 5 Series 520i 184 reaches 60 mph in 7.12 s, simulated on dry asphalt at 20 °C with a 1 ft rollout. It covers the standing quarter mile in 15.45 s at 90.3 mph.
What trap speed does each car run?
The BMW 520d (G30) trips the lights at 92.3 mph and the BMW 5 Series 520i 184 at 90.3 mph at the end of the quarter mile. These are theoretical times from a physics simulation, not measured runs.
Are these real measured times?
No. Every time on this page is produced by a physics simulation, not by a stopwatch at a drag strip. Each car is modelled from its published kerb mass, rated power, drivetrain and gearing, then trimmed until it matches its own published acceleration figures — 2 of 2 for the BMW 520d (G30) and 2 of 2 for the BMW 5 Series 520i 184. Conditions are identical for both cars: dry asphalt, 20 °C, sea level, 1 ft rollout.
