Infiniti M56 Mk IV

The Infiniti M56 Mk IV reaches 60 mph in 4.92 s and covers a standing quarter mile in 13.28 s, tripping the lights at 104.9 mph. It clears the first 60 ft in 2.05 s and the eighth mile in 8.60 s, reaching 100 mph in 11.52 s.

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

About the M56 Mk IV

The 2011 Infiniti M56 Mk IV is a rear-drive naturally aspirated saloon of 1,932 kg with 420 bhp, which works out at 217 bhp per tonne. Rear drive and 217 bhp per tonne make the launch the hard part of the run: 60 ft takes 2.05 s. Against the 2,929 cars in the set it is the 1,343rd quickest to 60 mph, and the 2nd quickest of the 18 Infinitis here. Its 104.9 mph trap speed sits about where its 0-60 puts it, so it launches and pulls in roughly equal measure. The simulation is trimmed to 9 of 10 published acceleration figures for this car.

Are these real measured times?
No. Every figure on this page is produced by a physics simulation, not by a stopwatch at a drag strip. The Infiniti M56 Mk IV is modelled from its published kerb mass, rated power, drivetrain and gearing, then trimmed until it reproduces 9 of its 10 published acceleration figures. Conditions are the same for every car in the set: dry asphalt, 20 °C, sea level, 1 ft rollout.

Figures regenerated 2026-09-01. Every number on this page is computed by the simulator at build time, so the page and the app can never disagree.
