Buick GNX

The Buick GNX reaches 60 mph in 4.81 s (100 km/h in 5.05 s) and covers a standing quarter mile in 13.20 s, tripping the lights at 103.4 mph. It clears the first 60 ft in 1.92 s and the eighth mile in 8.46 s, reaching 100 mph in 11.80 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 GNX

The 1987 Buick GNX is a rear-drive turbocharged car of 1,611 kg with 300 bhp, which works out at 186 bhp per tonne. Rear drive and 186 bhp per tonne make the launch the hard part of the run: 60 ft takes 1.92 s. Against the 14,946 cars in the set it is the 1,968th quickest to 60 mph, inside the fastest quarter, and the quickest of the 21 Buicks here. Its 103.4 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 5 of 7 published acceleration figures for this car.

Picked for a fair race, not just a matching 0-60: pace, power-to-weight and body shape all count, and at most one is from the same maker.

Questions

What is the Buick GNX 0-60 time?
The Buick GNX reaches 60 mph in 4.81 s, simulated on dry asphalt at 20 °C with a 1 ft rollout. That makes it the 1,968th quickest of the 14,946 cars in the set.
What is the Buick GNX quarter mile time?
13.20 s at 103.4 mph. It reaches the eighth mile in 8.46 s and clears the first 60 ft in 1.92 s. These are theoretical times from a physics simulation, not measured runs.
How much power does the Buick GNX have?
300 bhp and 1,611 kg, which is 186 bhp per tonne. It is rear-drive, turbocharged, with 5 gears and a quoted top speed of 200 km/h. These are theoretical times from a physics simulation, not measured runs.
What cars are comparable to the Buick GNX?
Closest here on pace: Jaguar XF 35t Mk II (4.83 s), Mercedes-Benz C 400 4MATIC W205 Pre Facelift (4.65 s), Subaru Impreza WRX STi 2.5 Turbo 300 (4.69 s). Each one can be raced against the Buick GNX 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 Buick GNX is modelled from its published kerb mass, rated power, drivetrain and gearing, then trimmed until it reproduces 5 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.
