Could be limited by gearing.

Not gearing, apparently there was a fuel cutoff chip at 124 mph coz the engineers were worried about front end lift and tyres rated to 125 mph. Anyway max power was at 4500 rpm and with the 0.67 overdrive minus the chip it could do about 140 mph...

Back in the eighties was a lot of new government-mandated pollution controls the engineers were just starting to deal with them.

Had a GN for 12 years. Stock hp# are about right. Here's the thing, turbo buicks are very easy to "turn up". Plus look at the torque the 3.8 sfi turbo makes. Let the engine breath better, a chip and traction, and it's a real heartbreaker.

The only bad thing is it was only available with an automatic transmission and only in one color, but at least that one color is black, the most awesome color for a car.

This was the last cool Buick. After 1988, Buick started building grannymobiles.

This car having more power than claimed is possibly the worst kept secret in automobile history.

The true GNX was designed for the FBI as a discreet chase vehicle for sting operations. The whisper-quiet TURBO 3.8 v6 was under-rated, the GNX version made about 380hp/450 lb/ft tq....there is your answer to the motivation of a 3600 lb BUICK.

have read on a US page over 300hp.. looking at the 0-100mph time that would fit in the range of similar heavy and powerfull BMW 335i or Audi RS2 or e36 M3

stock the car had more power than manufatur claimed... happens all around the world for different reasons. In the early 70´s normal in the USA to underrate the muscle cars for insurance reasons, sometimes manufactures underrate cars to go around new crash tests with stronger engine versions. Porsche did that once with the 968 Turbo S..they did not want to do a new series of crash tests for a 15 cars limited special edition... so they rated the power at 305hp... not a single car left the factory with less than 350hp.
Japan has the 280hp limit and it is well known that many JDM models in the passed had up to 340hp and more..
