There was a similar thread on here before the CRASH. And I don't think this car was brought up due to the fact it was ruled out of the Competition because it had only 2 doors.

"Fastest Production Sedan Ever" ?

Circa 1987, the Buick GNX was GM'* fastest production sedan ever and remains among Detroit'* quickest and most collectible vehicles of all time.

There has been some discussion about the GNX claim. The first issue: "is it a sedan?", and finally- "is the boast true?".

Sedan - 1. an enclosed automobile body having two or four doors and seating four or more persons on two full-width seats.

So let'* suppose the GNX is a production sedan- is it still the fastest? In over 10 years of Car & Driver, The author couldn't find anything to the contrary. There have been some very fast sedans- BMW M5 & Jaguar XJR and it seems lately the M5 may be in contention for the title. It'* 0-60 and quarter mile times are very similar to the C&D 1987 article, but with faster mph through the quarter.

What'* your thoughts?

i thought we were talking American sedans... in that case i'll take a brand spankin new AMG E55, please

i always thought a sedan meant 4 doors. hmmmmmmm gnx was very fast puppy. my buddy has a gn and it rocks........up to 125 when the speed limiter kicks in.

Buick Grand National'* and GNX'* aren't sedans,they're sport coupes,.....if you're talking American sedans,it would have to be the 400HP,Z06 engined Caddy CTS-V,[info from Car& Driver,9/03]..0-60 times of 4.7secs,1/4 mile in the low 13'*,and top speed in the low 160'*,....faster than both the BMW M-3 or M-5.John Heinricy,Director of GM'* high-performance-vehicle operations and a successful racer for more than 20 years,say'* he'* lapped the German Nordschleife((Northern loop of Germany'* legendary Nurburgring racetrack)in 8 minutes and 19 secs,....a better time than either M-car can turn.

yeah, i'm with him

I believe we mentioned the CTS-V in the other post, but it doesn't count because IT HASN'T BEEN RELEASED YET. It helps when the cars actually exist first. They can't be fast unless they are actually there.

If I had the money, E55 for the weekends and that purdy 01 M5 please.

400HP V8 in that M5, I believe it held the crown for the faster production "saloon" on the planet. That CTS-V is being built to fight the M5

Coupe - Usually a 2-door car with a fixed roof (as opposed to a convertible). However, 2-door cars sometimes are called sedans; these vehicles usually have a pillar, or post, between the driver'* (and passenger'*) side window and the quarter window. Vehicles without the pillar sometimes are referred to as hardtops.


Sedan - A term often used to describe any 4-door car. It also can be used to describe a 2- or 4-door car with a pillar, or post, between the driver'* (or passenger'*) side window and the quarter window. In this case, the pillar would differentiate a sedan from a hardtop.

thats why that my dream car
the fastest production car in 1987 ran low 13'* its was way ahead of it'* time and the caddy is running 13'* in 04 that pittiful they should be runnig 8'*

for all you tryin to prove some wrong!!!! I MEAN AMERICAN PRODUCTION AUTOMOBLIE IN "1987"
