Jensen Healey MK I

The Jensen Healey MK I reaches 60 mph in 8.40 s and covers a standing quarter mile in 16.47 s, tripping the lights at 85.4 mph. It clears the first 60 ft in 2.74 s and the eighth mile in 10.71 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 Healey MK I

The 1972 Jensen Healey MK I is a rear-drive naturally aspirated car of 950 kg with 139 bhp, which works out at 147 bhp per tonne. Rear drive and 147 bhp per tonne make the launch the hard part of the run: 60 ft takes 2.74 s. Against the 2,929 cars in the set it is the 2,714th quickest to 60 mph, and the 4th quickest of the 4 Jensens here. Its 85.4 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 9 of 9 published acceleration figures for this car.

139 bhp and 950 kg, which is 147 bhp per tonne. It is rear-drive, naturally aspirated, with 5 gears and a quoted top speed of 193 km/h.
What cars are comparable to the Jensen Healey MK I?
Closest here on pace: De Lorean DMC-12 European spec (8.40 s), Rover 827i Fastback (8.24 s), Rover Metro GTI (8.43 s). Each one can be raced against the Jensen Healey MK 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 Jensen Healey MK I is modelled from its published kerb mass, rated power, drivetrain and gearing, then trimmed until it reproduces 9 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.
