About the XPower 5.0 V8 405

The 2004 MG XPower 5.0 V8 405 is a rear-drive naturally aspirated saloon of 1,495 kg with 400 bhp, which works out at 267 bhp per tonne. Rear drive and 267 bhp per tonne make the launch the hard part of the run: 60 ft takes 2.22 s. Against the 14,946 cars in the set it is the 1,752nd quickest to 60 mph, inside the fastest quarter, and the 4th quickest of the 61 MGs here. Its 112.7 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 2 of 2 published acceleration figures for this car.

Questions

What is the MG XPower 5.0 V8 405 0-60 time?
The MG XPower 5.0 V8 405 reaches 60 mph in 4.61 s, simulated on dry asphalt at 20 °C with a 1 ft rollout. That makes it the 1,752nd quickest of the 14,946 cars in the set.
What is the MG XPower 5.0 V8 405 quarter mile time?
12.78 s at 112.7 mph. It reaches the eighth mile in 8.42 s and clears the first 60 ft in 2.22 s. These are theoretical times from a physics simulation, not measured runs.
How much power does the MG XPower 5.0 V8 405 have?
400 bhp and 1,495 kg, which is 267 bhp per tonne. It is rear-drive, naturally aspirated, with 5 gears and a quoted top speed of 282 km/h. These are theoretical times from a physics simulation, not measured runs.
What cars are comparable to the MG XPower 5.0 V8 405?
Closest here on pace: Rolls-Royce Wraith (4.56 s), Jaguar XJR (2010) (4.55 s), Vauxhall VXR8 Supercharged (4.59 s). Each one can be raced against the MG XPower 5.0 V8 405 in the panel at the top of this page. These are theoretical times from a physics simulation, not measured runs.
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 MG XPower 5.0 V8 405 is modelled from its published kerb mass, rated power, drivetrain and gearing, then trimmed until it reproduces 2 of its 2 published acceleration figures. Conditions are the same for every car in the set: dry asphalt, 20 °C, sea level, 1 ft rollout.
