About the SS Roadster (304 PS) Series 1
The 1965 Excalibur SS Roadster (304 PS) Series 1 is a rear-drive naturally aspirated roadster of 1,066 kg with 300 bhp, which works out at 282 bhp per tonne. Rear drive and 282 bhp per tonne make the launch the hard part of the run: 60 ft takes 2.50 s. Against the 14,946 cars in the set it is the 3,429th quickest to 60 mph, inside the fastest quarter. It traps higher than its 0-60 suggests — 106.0 mph, the 1,813th highest here — so it is a car that keeps going rather than one that simply leaves well. The simulation is trimmed to 7 of 7 published acceleration figures for this car.

Questions
What is the Excalibur SS Roadster (304 PS) Series 1 0-60 time?
The Excalibur SS Roadster (304 PS) Series 1 reaches 60 mph in 6.16 s, simulated on dry asphalt at 20 °C with a 1 ft rollout. That makes it the 3,429th quickest of the 14,946 cars in the set.
What is the Excalibur SS Roadster (304 PS) Series 1 quarter mile time?
14.43 s at 106.0 mph. It reaches the eighth mile in 9.65 s and clears the first 60 ft in 2.50 s. These are theoretical times from a physics simulation, not measured runs.
How much power does the Excalibur SS Roadster (304 PS) Series 1 have?
300 bhp and 1,066 kg, which is 282 bhp per tonne. It is rear-drive, naturally aspirated, with 5 gears and a quoted top speed of 209 km/h. These are theoretical times from a physics simulation, not measured runs.
What cars are comparable to the Excalibur SS Roadster (304 PS) Series 1?
Closest here on pace: Morgan Plus 8 3.5 Mk II (6.09 s), Lamborghini 350GT (5.92 s), Lamborghini Miura P400SV (6.14 s). Each one can be raced against the Excalibur SS Roadster (304 PS) Series 1 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 Excalibur SS Roadster (304 PS) Series 1 is modelled from its published kerb mass, rated power, drivetrain and gearing, then trimmed until it reproduces 7 of its 7 published acceleration figures. Conditions are the same for every car in the set: dry asphalt, 20 °C, sea level, 1 ft rollout.
