Alpina Z4 Roadster S

The Alpina Z4 Roadster S reaches 60 mph in 4.87 s (100 km/h in 5.11 s) and covers a standing quarter mile in 13.15 s, tripping the lights at 107.3 mph. It clears the first 60 ft in 2.05 s and the eighth mile in 8.52 s, reaching 100 mph in 11.31 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 Z4 Roadster S

The 2003 Alpina Z4 Roadster S is a rear-drive naturally aspirated roadster of 1,416 kg with 296 bhp, which works out at 209 bhp per tonne. Rear drive and 209 bhp per tonne make the launch the hard part of the run: 60 ft takes 2.05 s. Against the 14,946 cars in the set it is the 2,037th quickest to 60 mph, inside the fastest quarter, and the 39th quickest of the 55 Alpinas here. Its 107.3 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 10 published acceleration figures for this car.

Questions

What is the Alpina Z4 Roadster S 0-60 time?
The Alpina Z4 Roadster S reaches 60 mph in 4.87 s, simulated on dry asphalt at 20 °C with a 1 ft rollout. That makes it the 2,037th quickest of the 14,946 cars in the set.
What is the Alpina Z4 Roadster S quarter mile time?
13.15 s at 107.3 mph. It reaches the eighth mile in 8.52 s and clears the first 60 ft in 2.05 s. These are theoretical times from a physics simulation, not measured runs.
How much power does the Alpina Z4 Roadster S have?
296 bhp and 1,416 kg, which is 209 bhp per tonne. It is rear-drive, naturally aspirated, with 6 gears and a quoted top speed of 265 km/h. These are theoretical times from a physics simulation, not measured runs.
What cars are comparable to the Alpina Z4 Roadster S?
Closest here on pace: Jaguar F-Type V6 (4.75 s), Nissan 370Z (4.84 s), Lotus Elise S (4.87 s). Each one can be raced against the Alpina Z4 Roadster S 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 Alpina Z4 Roadster S 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.
