About the Islero 3.9 V12 S 351

The 1968 Lamborghini Islero 3.9 V12 S 351 is a rear-drive naturally aspirated coupe of 1,375 kg with 346 bhp, which works out at 252 bhp per tonne. Rear drive and 252 bhp per tonne make the launch the hard part of the run: 60 ft takes 2.43 s. Against the 14,946 cars in the set it is the 2,837th quickest to 60 mph, inside the fastest quarter, and the 72nd quickest of the 83 Lamborghinis here. Its 102.5 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 Lamborghini Islero 3.9 V12 S 351 0-60 time?
The Lamborghini Islero 3.9 V12 S 351 reaches 60 mph in 5.64 s, simulated on dry asphalt at 20 °C with a 1 ft rollout. That makes it the 2,837th quickest of the 14,946 cars in the set.
What is the Lamborghini Islero 3.9 V12 S 351 quarter mile time?
14.05 s at 102.5 mph. It reaches the eighth mile in 9.24 s and clears the first 60 ft in 2.43 s. These are theoretical times from a physics simulation, not measured runs.
How much power does the Lamborghini Islero 3.9 V12 S 351 have?
346 bhp and 1,375 kg, which is 252 bhp per tonne. It is rear-drive, naturally aspirated, with 5 gears and a quoted top speed of 261 km/h. These are theoretical times from a physics simulation, not measured runs.
What cars are comparable to the Lamborghini Islero 3.9 V12 S 351?
Closest here on pace: Ferrari 275 GTB 3.3 V12 280 (5.65 s), Ferrari 275 GTB 3.3 V12 290 (5.55 s), Ferrari 250 GT 3.0 V12 280 (5.50 s). Each one can be raced against the Lamborghini Islero 3.9 V12 S 351 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 Lamborghini Islero 3.9 V12 S 351 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.
