Monteverdi Hai 450 SS

The Monteverdi Hai 450 SS reaches 60 mph in 5.61 s (100 km/h in 5.84 s) and covers a standing quarter mile in 13.78 s, tripping the lights at 108.1 mph. It clears the first 60 ft in 2.45 s and the eighth mile in 9.14 s, reaching 100 mph in 12.01 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 Hai 450 SS

The 1970 Monteverdi Hai 450 SS is a rear-drive naturally aspirated supercar of 1,247 kg with 425 bhp, which works out at 341 bhp per tonne. Rear drive and 341 bhp per tonne make the launch the hard part of the run: 60 ft takes 2.45 s. Against the 14,946 cars in the set it is the 2,796th quickest to 60 mph, inside the fastest quarter. It traps higher than its 0-60 suggests — 108.1 mph, the 1,567th highest here — so it is a car that keeps going rather than one that simply leaves well. The simulation is trimmed to 8 of 10 published acceleration figures for this car.

Picked for a fair race, not just a matching 0-60: pace, power-to-weight and body shape all count, and at most one is from the same maker.

Questions

What is the Monteverdi Hai 450 SS 0-60 time?
The Monteverdi Hai 450 SS reaches 60 mph in 5.61 s, simulated on dry asphalt at 20 °C with a 1 ft rollout. That makes it the 2,796th quickest of the 14,946 cars in the set.
What is the Monteverdi Hai 450 SS quarter mile time?
13.78 s at 108.1 mph. It reaches the eighth mile in 9.14 s and clears the first 60 ft in 2.45 s. These are theoretical times from a physics simulation, not measured runs.
How much power does the Monteverdi Hai 450 SS have?
425 bhp and 1,247 kg, which is 341 bhp per tonne. It is rear-drive, naturally aspirated, with 5 gears and a quoted top speed of 290 km/h. These are theoretical times from a physics simulation, not measured runs.
What cars are comparable to the Monteverdi Hai 450 SS?
Closest here on pace: Lamborghini Miura P400 (5.70 s), Ferrari 328 GTB (5.50 s), Ferrari 250 GTO (5.57 s). Each one can be raced against the Monteverdi Hai 450 SS 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 Monteverdi Hai 450 SS is modelled from its published kerb mass, rated power, drivetrain and gearing, then trimmed until it reproduces 8 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.
