MG MGA Twin-Cam Roadster Mk I

The MG MGA Twin-Cam Roadster Mk I reaches 60 mph in 11.99 s (100 km/h in 12.72 s) and covers a standing quarter mile in 18.83 s, tripping the lights at 74.8 mph. It clears the first 60 ft in 3.26 s and the eighth mile in 12.30 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 MGA Twin-Cam Roadster Mk I

The 1960 MG MGA Twin-Cam Roadster Mk I is a rear-drive naturally aspirated roadster of 991 kg with 109 bhp, which works out at 110 bhp per tonne. Rear drive and 110 bhp per tonne make the launch the hard part of the run: 60 ft takes 3.26 s. Against the 14,946 cars in the set it is the 12,827th quickest to 60 mph, and the 60th quickest of the 61 MGs here. Its 74.8 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.

Questions

What is the MG MGA Twin-Cam Roadster Mk I 0-60 time?
The MG MGA Twin-Cam Roadster Mk I reaches 60 mph in 11.99 s, simulated on dry asphalt at 20 °C with a 1 ft rollout. That makes it the 12,827th quickest of the 14,946 cars in the set.
What is the MG MGA Twin-Cam Roadster Mk I quarter mile time?
18.83 s at 74.8 mph. It reaches the eighth mile in 12.30 s and clears the first 60 ft in 3.26 s. These are theoretical times from a physics simulation, not measured runs.
How much power does the MG MGA Twin-Cam Roadster Mk I have?
109 bhp and 991 kg, which is 110 bhp per tonne. It is rear-drive, naturally aspirated, with 5 gears and a quoted top speed of 185 km/h. These are theoretical times from a physics simulation, not measured runs.
What cars are comparable to the MG MGA Twin-Cam Roadster Mk I?
Closest here on pace: Saab 9-3 Convertible 2.0 130 (11.96 s), Suzuki Swift Cabrio 1.3 68 (11.82 s), Holden Astra TwinTop 1.6 115 (12.06 s). Each one can be raced against the MG MGA Twin-Cam Roadster Mk I 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 MG MGA Twin-Cam Roadster 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.
