K1 Roadster

The K1 Roadster reaches 60 mph in 4.64 s and covers a standing quarter mile in 13.24 s, tripping the lights at 103.8 mph. It clears the first 60 ft in 2.05 s and the eighth mile in 8.50 s, reaching 100 mph in 12.18 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 Roadster

The 2008 K1 Roadster is a rear-drive naturally aspirated roadster of 1,128 kg with 237 bhp, which works out at 210 bhp per tonne. Rear drive and 210 bhp per tonne make the launch the hard part of the run: 60 ft takes 2.05 s. Against the 2,929 cars in the set it is the 1,187th quickest to 60 mph. It leaves better than it pulls: 103.8 mph at the lights is only the 1,421st highest here, so its 0-60 flatters what it does further out. The simulation is trimmed to 9 of 10 published acceleration figures for this car.

Questions

What is the K1 Roadster 0-60 time?
The K1 Roadster reaches 60 mph in 4.64 s, simulated on dry asphalt at 20 °C with a 1 ft rollout. That makes it the 1,187th quickest of the 2,929 cars in the set.
What is the K1 Roadster quarter mile time?
13.24 s at 103.8 mph. It reaches the eighth mile in 8.50 s and clears the first 60 ft in 2.05 s.
How much power does the K1 Roadster have?
237 bhp and 1,128 kg, which is 210 bhp per tonne. It is rear-drive, naturally aspirated, with 6 gears and a quoted top speed of 245 km/h.
What cars are comparable to the K1 Roadster?
Closest here on pace: Chrysler Crossfire SRT-6 Roadster (4.66 s), Opel Speedster Turbo (4.69 s), BMW M3 E46 (4.66 s). Each one can be raced against the K1 Roadster 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 K1 Roadster is modelled from its published kerb mass, rated power, drivetrain and gearing, then trimmed until it reproduces 9 of its 10 published acceleration figures. Conditions are the same for every car in the set: dry asphalt, 20 °C, sea level, 1 ft rollout.
