Iso Rivolta Grifo L GL350 Series I

The Iso Rivolta Grifo L GL350 Series I reaches 60 mph in 6.21 s and covers a standing quarter mile in 14.59 s, tripping the lights at 99.1 mph. It clears the first 60 ft in 2.56 s and the eighth mile in 9.64 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 Grifo L GL350 Series I

The 1967 Iso Rivolta Grifo L GL350 Series I is a rear-drive naturally aspirated car of 1,594 kg with 350 bhp, which works out at 220 bhp per tonne. Rear drive and 220 bhp per tonne make the launch the hard part of the run: 60 ft takes 2.56 s. Against the 2,929 cars in the set it is the 2,044th quickest to 60 mph, and the quickest of the 3 Iso Rivoltas here. It traps higher than its 0-60 suggests — 99.1 mph, the 1,804th highest here — so it is a car that keeps going rather than one that simply leaves well. The simulation is trimmed to 7 of 9 published acceleration figures for this car.

What cars are comparable to the Iso Rivolta Grifo L GL350 Series I?
Closest here on pace: Morgan Plus 8 3.5 Mk II (6.09 s), Gordon Keeble G.K.1 (5.92 s), Amc AMX (5.92 s). Each one can be raced against the Iso Rivolta Grifo L GL350 Series I in the panel at the top of this page.
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 Iso Rivolta Grifo L GL350 Series I is modelled from its published kerb mass, rated power, drivetrain and gearing, then trimmed until it reproduces 7 of its 9 published acceleration figures. Conditions are the same for every car in the set: dry asphalt, 20 °C, sea level, 1 ft rollout.
