2004 Pontiac Grand Prix: A New Sedan-Only Generation and the Comp G

This record's own dek describes 2004 as a new sedan-only Grand Prix, with the supercharged GTP and its Comp G package. This record's own overview states that the compiled engine tables list a naturally aspirated 3.8-liter V6 at 200 hp and 230 lb-ft and a supercharged 3.8-liter V6 at 260 hp and 280 lb-ft for 2004, both SAE net as compiled with no rpm given; it also states that no 2004 production figure was found in an accessible published source, and that MotorWeek tested a 2004 GTP with the Comp G suspension package, the supercharged 3.8 V6 at 260 hp and 280 lb-ft, a four-speed automatic with TapShift, and a 0-60 mph time of 6.5 seconds, giving launch prices of $22,395 for the GT and $26,495 for the GTP, with the Comp G test car at $27,890.^1,2

This record's own keyFacts section states that the 2004 catalog, printed March 2003, names the Oshawa Assembly Plant #2 near Toronto, Ontario as the car's plant and lists three models, GT1, GT2 and GTP, all with a four-speed automatic, with the GTP's Competition Group Package adding specific suspension tuning, TAPshift steering-wheel paddles, the InfoTech Package, StabiliTrak Sport, Magnasteer II, P225/55R17 V-rated tires on 10-spoke wheels, red brake calipers and a 3.29 axle. This record's own identification section carries that same assembly plant as its single entry.

This record's own production section carries a single row, 131,551 Grand Prix US deliveries for calendar year 2004, explicitly noted as covering all Grand Prix trims and model years rather than model-year production; its own notes state plainly that no model-year production figure was found for 2004 in an accessible published source, and that the compiled Standard Catalog table stops at 2002. This record's own unpublishedLeads section carries a forum estimate that about 15,000 2004 Grand Prix GTPs were built with the Competition Group package, held back as approximate with no source named.³

This record's own prices section carries seven figures: MotorWeek's own launch prices of $22,395 for the GT and $26,495 for the GTP with a $27,890 as-tested Comp G sticker, plus four pontiac.com MSRPs from an April 30, 2004 capture, $22,835 for the GT1, $24,735 for the GT2 (with a $25,060 example shown), $26,935 for the GTP, and $28,330 for the GTP with the Competition Group Package. This record's own conflicts section flags that same price gap directly, MotorWeek's GT and GTP launch prices against pontiac.com's own GT1 and GTP figures, each pair differing by $440, with this record's own treatment note observing the gap probably reflects different dates or destination treatment that neither source states.²

This record's own engines section carries the two entries matching the overview, the naturally aspirated 3.8-liter standard on the GT1 and GT2 and the supercharged 3.8-liter standard on the GTP with or without the Competition Group Package. This record's own conflicts section carries a second dispute over the naturally aspirated engine's own torque, the brochure's 230 lb-ft against the spec sheet's own printed 225 lb-ft at 4,000 rpm, with this record's own treatment note stating two Pontiac documents of the same model year disagree and that the catalog, the compiled table and later sheets use 230. This record's own transmissions section lists the four-speed automatic as the sole transmission for the year.^1,4

This record's own options section itemizes the Comp G suspension package and Competition Group Package by their own full content, a Driver's Package, a Lifestyle Package, a Premium Lighting Package, an InfoTech Package, a Leather Trim Package, a Premium Audio Package, head-curtain side-impact air bags, a power spoiler-type sunroof, XM Satellite Radio, OnStar, an engine block heater, and four distinct wheel styles from a 16-inch steel wheel with bolt-on cover up to the 17-inch 10-spoke Competition Group wheel.

This record's own paint table lists eight colors, and this record's own interiors section carries four entries: Parchment cloth, Dark Pewter cloth, Parchment leather, and Dark Pewter leather, each with matching interior trim. This record's own specifications section gives a 110.5-inch wheelbase, 198.3-inch overall length, 55.9-inch overall height, front/rear track of 61.6/61.3 inches, curb weights of 3,477 pounds for the GT1, 3,484 for the GT2 and 3,583 for the GTP, axle ratios of 3.05 for the base 3800, 2.93 for the GTP and 3.29 for the GTP with Competition Group, cargo volumes of 16.0/45.7/57.0 cubic feet by seat configuration, an approximate 17.0-gallon fuel tank, full interior dimensions, and a 0.31 drag coefficient. This record's own performance section carries MotorWeek's own single figure, the 6.5-second 0-60 mph time for the Comp G GTP, matching the overview.^4,2
