About the GranSport Spyder 4.2 GT V8 390

The 2006 Maserati GranSport Spyder 4.2 GT V8 390 is a rear-drive naturally aspirated roadster of 1,620 kg with 385 bhp, which works out at 238 bhp per tonne. Rear drive and 238 bhp per tonne make the launch the hard part of the run: 60 ft takes 2.12 s. Against the 14,946 cars in the set it is the 1,657th quickest to 60 mph, inside the fastest quarter, and the 34th quickest of the 79 Maseratis here. Its 111.3 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 Maserati GranSport Spyder 4.2 GT V8 390 0-60 time?
The Maserati GranSport Spyder 4.2 GT V8 390 reaches 60 mph in 4.50 s, simulated on dry asphalt at 20 °C with a 1 ft rollout. That makes it the 1,657th quickest of the 14,946 cars in the set.
What is the Maserati GranSport Spyder 4.2 GT V8 390 quarter mile time?
13.05 s at 111.3 mph. It reaches the eighth mile in 8.52 s and clears the first 60 ft in 2.12 s. These are theoretical times from a physics simulation, not measured runs.
How much power does the Maserati GranSport Spyder 4.2 GT V8 390 have?
385 bhp and 1,620 kg, which is 238 bhp per tonne. It is rear-drive, naturally aspirated, with 6 gears and a quoted top speed of 283 km/h. These are theoretical times from a physics simulation, not measured runs.
What cars are comparable to the Maserati GranSport Spyder 4.2 GT V8 390?
Closest here on pace: Ferrari F355 Spider (4.54 s), Chrysler Crossfire Roadster SRT6 3.2 V6 335 (4.47 s), Jaguar XKR convertible (4.64 s). Each one can be raced against the Maserati GranSport Spyder 4.2 GT V8 390 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 Maserati GranSport Spyder 4.2 GT V8 390 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.
