As far as top speed, the 201mph Ferrari F40 was the fastest. However, the 1987 GNX was a muscle car and was designed for acceleration. In this area, it was by far the fastest.

The most popular were manufactured between 1985 to 1987 but there was a 1983 Grand National that was manufactured as well. Buick started this whole deal with the Turbo Buick back in 1976 with the 1976 Century Indy Pace Car which was a 231 V6 Indy Pace Car that out accelerated the Buick 455 from 90 to 110 mph! 8-) shortly thereafter the Turbo V6 ended up in Buick production as "Hotair" turbos (no intercooler) and culminated in 1986 and 1987 as the "BadBoy" intercooled Buick Grand Nationals with the 1987 being the fastest US production car for 1987. Then Pontiac used the Buick Turbo V6 in the 1989 Trans Am. And let's not forget the awesome 1987 GNX...LOL. See the following website for all the good information on this outstanding vehicle ;-) : http://home.flash.net/~rjgeorge To see a "Real" Grand National go to www.tufenuf.net and click on "Grocery Getter" That's not my Buick GN.........Mines faster 8-) TommyTrouble I would also like to add that the same turbo V6 was also offered in the 1981 Chevy Monte Carlo. Buick Regal Turbos before the famed GN were called T Types.
The 1997 Camaro had a 3.8 V6 producing 200 H.P.=The first Grand National in 1982 had a 4.1 V6 producing 125 H.P. No Grand Nation was produced in 1983. The 1984 was the first year of the 3.8 V6. The 1986 Buick Grand National had a 3.8 V6 that was Turbocharged and produced 235 H.P. The 1987 Produced 245 H.P. The 1987 GNX turbocharged V6 of the Grand National was completely reworked by McLaren Engines. The turbo and intercooler were both upgraded and the engine's computer was reprogrammed. The four speed automatic gearbox received its own oil cooler. It produced 276 H.P. ==Production:==Grand Nationals: 20,193==GNX: 547=

This would depend on what engine they have; El Camino could possibly have up to a stock 425hp 454ci (not necessarily from the factory). If it were a SS (Super Sport) and had the towing package, depending again on the year, it would have a posi-traction rear end. Also it would depend on the year of the GN. The last year (1987) they were made they were underrated at 276hp.
