2006 Pontiac Grand Prix: The GXP and GT, the GTP Name Dropped

This record's own dek states that the GXP LS4 V8 and the supercharged V6 both continue for 2006. This record's own overview states that the compiled engine tables list a 3.8-liter V6 at 200 hp and 230 lb-ft, a supercharged 3.8-liter V6 at 260 hp and 280 lb-ft, and the 5.3-liter LS4 V8 at 303 hp and 323 lb-ft, all SAE net as compiled with no rpm given; it also states that no model-year production figure was found, and that US calendar-year 2006 sales of all Grand Prix were 108,634, per GoodCarBadCar's aggregator table.^1,2

This record's own keyFacts section states that for 2006 the line was the Grand Prix with the 200-hp 3800 V6, the Grand Prix GT with the supercharged 260-hp V6, and the GXP with the 303-hp LS4 V8, all with a four-speed automatic, that a Special Edition Appearance Package with fascia extensions, body-color grilles, side aero channels and 17-inch Midnight Silver wheels arrived in November 2005, and that the catalog names the Oshawa #2, Ontario plant. This record's own identification section carries that same assembly plant as its single entry.³

This record's own production section carries a single row, 108,634 US sales for calendar year 2006, credited to automakers and the Automotive News Data Center and explicitly noted as calendar-year sales of all Grand Prix trims mixing model years rather than model-year production; its own notes state plainly that no model-year production figure was found. This record's own unpublishedLeads and conflicts sections are both empty for the year.²

This record's own prices section carries four MSRPs from pontiac.com, with destination not stated: $23,095 for the Grand Prix sedan from an October 1, 2005 capture and a later $22,990 figure from an October 26, 2005 capture, $26,745 for the GT, and $29,395 for the GXP, the last two figures stable across both captures. This record's own engines section carries the three entries matching the overview, the 3.8-liter standard on the base Grand Prix sedan, the supercharged 3.8-liter standard on the GT with this record's own availability note stating the GTP name was dropped for 2006, and the LS4 5.3-liter V8 standard on the GXP. This record's own transmissions section lists a single entry, the four-speed electronically controlled overdrive automatic, the only transmission for the year, with TAPshift paddles on the GXP.^1,4

This record's own options section itemizes the Special Edition Package by its own full content, a Sport Package, a Preferred Package, a Premium Package, a Security Package, a Sun and Sound Package, and five distinct wheel styles from a 16-inch painted aluminum wheel standard on the Grand Prix up to the 18-inch forged polished aluminum wheel standard on the GXP.³

This record's own paint table lists eight colors, and this record's own interiors section carries six entries: Ebony cloth, Sand cloth, Ebony leather-appointed seating with Mini-perf inserts on Grand Prix and GT, Sand leather-appointed seating with the same inserts, and Ebony and Sand leather-appointed seating with UltraLux Suede inserts specific to the GXP, all drawn from the same 2006 brochure's own Interior Colors listings for the Grand Prix, GT and GXP.

This record's own specifications section gives a shared 110.5-inch wheelbase, 198.3-inch length, 71.6-inch width and 55.9-inch height, front/rear track of 61.6/61.3 inches generally and 63.5/61.7 for the GXP, curb weights of 3,477 pounds for the Grand Prix, 3,484 for the GT and 3,600 for the GXP, the GXP's own vented cross-drilled brake rotors at 12.7 inches front and 12.0 inches rear with PBR calipers, an approximate 17-gallon fuel tank, 16.0 cubic feet of trunk space and a 1,000-pound maximum trailer weight across all models.
